Reading, writing, and ‘Oh Canada’ – Week 5

Monday 17th September to Wednesday 19th September

Well its mid week of Week 5 back on land, and it’s been hectic to say the least. When I say hectic I mean we have had reports to do, papers to read, and final proposals to write. Monday morning we went to Lacrover Farm again and did some manual labour, pulling up of pea plants to be exact, but we got to feed the four pigs they have which had grown quite substantially since a fortnight ago, so that was cool. I really do plan on posting pics up on the Beam Reach gallery of my trip so far, but have just been too busy to sit down and wait for them to upload, but I promise I will get on that. So I had hoped to go out with Giles on Mon arvo but no whales were reported. Same thing happened on Tuesday and today (Wednesday), no whales. I felt bad for the other group as they have now had 3 days with an orca sighting, and therefore no data collection. Thankfully though that is an advantage of my project where I’m not relying completely on the presence of whales, all I need is boats, and there are plenty of those around. So I’m writing this as a break from my proposal that is due tomorrow. We have had a few little exercises/reports so far this week, as well as readings for journal club so as I said it’s been a little bit hectic. Had another Whale Museum lecture this week, Giles (Debbie) spoke about her PhD work, but as I had already been out with her I kinda already knew what she was working on. Still, it’s fascinating work and very thorough. So my proposal is due tomorrow so I better get back to the finishing touches. Off to Victoria Canada tomorrow arvo as well! We get 2 days off every fortnight so Ash and I decided we would go to Victoria as she had never been, and I really like it, plus I want to utilise the opportunity to speak to some whale watch operators about doing some drive-bys for me next week when I’m at sea. Well better get back to my proposal.

Thursday 20th September to Sunday 23rd September

I’m writing this on the boat on Sunday night after spending 2 days in
Victoria, Canada. So here’s how the last few days went down…

Thursday arvo I handed my proposal into Val after having a chat with him about it. I’m pretty happy with it because I know it’s feasible, and I know what I have to do. It definitely needs some fine tuning but it’s well within the scope of the program, and somewhat original. I mean it changes now anyway as it no longer becomes a proposal, but an actual report. Anyway, it’s in now so will get feedback on it early next week no doubt. So Thurs arvo Ash and I caught the Washington State Ferry across to
Sidney, British Columbia, for a total of $6. Bargain! We met a couple on board that we chatted to and they had just been on a whale watching tour earlier that day with a local San Juan operator, Jim Maya, who we have met, and Jim said he would be more than happy to do some drive-bys for me to get some recordings. The couple were asking us about our research and about the killer whales in general, and it was really good to be able to spread our knowledge to members of the general public. So we got into Sidney just after 5pm, then caught a public bus to
Victoria. I had done this trip a few times before when I stayed in Victoria and was going to
Sidney to speak to the whale watch operators, so knew where we had to get off and how long it would take. Ash and I grabbed dinner and a few drinks and headed out to check out the Victorian night life. We went to a pub called Darcy’s and ended up meeting this guy who was a restaurant manager in town, he had a few connections and after Darcy’s we got into a club for free. It all closes pretty early on Thurs night in
Victoria but it was a great night and we had organised on the Fri to go grab lunch at the restaurant this guy manages. So Friday Ash and I grabbed lunch at the restaurant, with a discount from our newly made manager mate, then went down to Prince of Whales whale watching company to speak to them about possibly doing drive-bys for me next week when I’m out on the Gato Verde. Well, it went exceptionally well, much better than I had anticipated. I seriously thought I would have to go to several operators but Laila at Prince of Whales was awesome. I chose Prince of Whales because I had spoken to them 7 weeks ago when I was in
Victoria sussing out possible job opportunities for next year (I have a 12 month Canadian working visa) and they said get in touch with them when I finish this program. The woman I spoke to 7 weeks ago that works there also does acoustic research on porpoises but when I contacted her again a few days ago I was unable to get in touch with her. However, that didn’t really hinder me in anyway as Laila (head of land operations) was extremely positive and also a conservationist, so when I explained what I ultimately planned to do in my research she was more than happy to help out. So we teed up next week, Ash and I got chatting to her about all things marine mammals, and she asked if we wanted to go out on the last tour of the day, we didn’t have any plans, so agreed. Oh yeah, should also mention, it was for free! I guess when you think about it it’s pretty funny, we study whales for 10 weeks, then on our days off we go to
Canada, and go whale watching! Still, we saved $70 each which is bloody awesome, and what was even more awesome was that it was the best killer whale experience of my life! Yep, it topped the one we had on our second day out on the water. It truly was phenomenal. Here’s what happened:

We jumped into our ‘Mustang’ suits (full-bodied orange suits designed to keep u warm and act as a flotation device should we fall into the drink) and hopped aboard the Zodiac (steel hulled open inflatable boat). The driver, aka ‘Radar’, announced he had some acoustic researchers on board, and Ash and I signalled him with much professionalism as we jumped into the seats up front. Laila said these seats are the best as they are the ones where you get the real ‘Zodiac experience’. We have been travelling a maximum of 6-7 knots out on the water while aboard the ‘Gato Verde’ so we certainly felt the need for speed, and the zodiacs (very common whale watch operator vessel in these parts) certainly zip along (~25-30 knots). The ride out was awesome to say the least. It was spitting with rain so the droplets felt like little pin pricks on your face but it was all worth it with the 2ft swells and the air-time we were getting of the waves. It took about 40 min to get to where J pod and some of the L’s were, but waters were really calm and we were only one of three vessels out there (west side of San Juan Island around Eagle Pt). The ‘Gato Verde’ was out there also so I called them up on the radio and we had a chat then went over to say G’Day. It was just after 5pm by this stage so the GV had to leave to get to an anchorage before dark, and the other whale watch boat left, so we were the only one’s out there with the whales. We positioned ourselves in front of the whales and 100m from their general direction if travel and watched spyhops, breaches, lots of tail slaps, and just general playful behaviour. Next thing we knew a group of about 10 individuals somewhat spread out started heading toward our boat and before we could get out of the way they were right next to us. It was un-bloody-believable! We had a whale swim just under the surface the entire length of the boat (it was as long as the boat) just looking at us, then we had whales surface about 2m from where we were standing, their breaths seeming soo loud and their dorsal fins coming up to my eye level. It was truly spectacular. The water was like glass which just made the experience that much more beautiful. Now when whales decide to come and check you out (it rarely happens but as we were the only boat out there I guess they were curious) the best thing you can do is just let them pass and when you think it is safe, engage the ignition and slowly motor away to a safe distance. In this instance the whales were actually curious and so came right up to us as they swam past. The last thing you should do is try and get out of their way as the ignition of the engine and then the engagement of the gears actually makes quite a large “clunk” underwater, and so may startle the whales. I know this because I felt like I was deafened when I had the headphones on right where a boat engaged its gears. Furthermore, engaging propellers runs the risk of bumping into whales when they are underwater and out of driver sight. So we just floated there silently while killer whales milled around our boat and swam off. Radar (the driver) had a basic hydrophone that he deployed and the vocalisations we got were just unbelievable! Ash and I were amazed and really wish we had a recorder at that time. We were meant to be the “researchers” but we couldn’t contain our excitement and kept telling the others on board that what you are witnessing is absolutely amazing and a one in a lifetime experience. We have been out on the water for 2 weeks and pretty much all of the time the whales are little black dots in the water, so this experience is one I will forever treasure. The passengers on board (7 in total incl. us) were asking us questions all about the orcas and between us, Ash and I could answer them all. The driver kept pretty quiet, whether or not because we were on board I don’t know, but he had been doing it for 12 years so knew his stuff. Anyway, it was great practice for me as the driver could be me this same time next year. I got some great video clips but it was often hard to properly focus as it was cloudy and drizzly for parts of it. One of the highlights I think was when J42 calf and it’s mum (sex of calf unknown) came less than 5m from the boat and the calf was spyhopping and jumping around just playing like a typical child would, and mum was just hanging there in the water keeping a close eye on her playful child. J42 in it’s playful behaviour all of a sudden vocalised as it came up out of the water, and Ash and I just looked at each other in amazement then looked at Radar and he was just as surprised. It was absolutely amazing! We eventually had to leave the orcas and head back to Victoria but it was definitely a memory that will stick with me and one that I’m very appreciative to have witnessed. Some days you just get lucky.

So Ash and I headed out that night to check out more of the Victorian nightlife. It was good to get across to Victoria and head out in the evenings, as you don’t really get the opportunity inFriday
Harbor, so let’s just say we enjoyed our two nights away from the labs. Saturday we walked around Victoria, Ash did some shopping, then it was a bus back to Sidney and a ferry back to

Friday
Harbor in the evening. One would think that the troubles I had the first time I went back in to the
US in August would be well behind me and I could expect to go straight through customs and onto the ferry, but ahh, no. I’ve said it before, US Customs is a bloody joke! For some stupid reason the old bloke that stamped my student visa back in mid August when I entered the US from
Canada stamped mid September on it, I have no idea why. The woman at the customs desk in
Sidney looked at it weirdly and asked me all about it and why it was stamped for September when the program ends at the end of October. Of course I had no idea, but I told her that the old guy at the border that processed my student visa didn’t appear to know what he was doing. She couldn’t work out what was going on as Ash’s documentation was all fine so I had to step aside while she processed everyone else. While that was happening I felt a sense of deja vu, as this is what happened last time in August and I was holding people up on the bus, and now I had scenarios of what the hell I would do if they wouldn’t let me back in to the US. Fortunately enough the woman issued me with a new visa card and I was allowed through. When on the ferry a lot of the people in the line were saying how lucky I was as most US Customs officials aren’t as nice as this woman was. Guess I got lucky, but still, I had all the documentation necessary and it ended up being an error on their behalf… bloody US Customs! Anyway, Ash and I got back to

Friday
Harbor and pretty much crashed out.

Today, Sunday, we had the changeover from the JaMi group atRoche
Harbor. Marla Holt gave us a talk (who had spoken at the

Whale
Museum a few weeks back) and then she hopped aboard and will be spending the next three days with us. Marla is a post-doc with a great deal of hydro-acoustics knowledge and experience so she will be a great asset to us all these next three days I’m sure. I was hauled up the mast this afternoon, 63 feet above the water, it was awesome! Got a great view of
Mitchell
Bay (

Snug
Harbor) and the sunset where we are anchored tonight. If you have seen the film ’28 Days’ with Sandra Bullock and can recall the scene where they must climb a wooden structure all harnessed up, and the gay blonde guy with glasses is climbing… well if you’ve seen it I don’t need to go on. Let’s just say I’m a bit tender at the moment, but it was worth it to be that high up above the water.

So just before I head to bed I have to make sure that I have a towel above and below my mattress as yesterday the JaMi group had some high seas and water splashed into the vents of the forward births and so the mattresses got quite wet. Todd and I spent an hour this afternoon soaking up water in our respective births. Fun times. I plan on getting boat recordings this week so hopefully all goes well.

Transportation contemplation

It’s a silent night in Roche Harbor — a stark contrast to the tempest last night. Team JaMi is settled down to rest up for a big day on the water tomorrow. Team VaTo is clean and polished back at the labs, surely reveling in the broadband access at the Labs.

The highlight for me today was the afternoon class discussion of sustainability and the transportation sector. After I gave a brief motivational introduction, asking “How should sustainability scientists BE?,” Jason gave some statistics on the relative environmental impacts of different vehicles.

Here are some of the numbers Jason noted:

Mode of transport of freight within the U.S.:  trucks 32%, rail 28%, water 16% — (that’s 76% diesel!)

gCO2 produced per ton-km for different vehicles: boat 15, rail 22, bus 30, heavy truck 90, motorcycle 120, car 275, light duty vehicle 400.

The teams this year have done a much better job of tracking the resources we use and the waste we generate while aboard the Gato Verde.  I’m excited to read what sustainability improvements the students recommend  and to finally quantify with metrics like g CO2/ton-km how Gato Verde compares to other human transportation technologies.  With biodiesel emissions and production properly accounted for, will Gato Verde be close to the boat emmission rate or way below it?

Traveling with transients

Monday, October 1, 2007

Worked our way south through Mosquito Pass after a quiet night in Roche Harbor. Headed southwards with the flood tide, intending to return on the ebb if we didn’t encounter the whales down south. As we passed Lime Kiln mid-Haro, we started hearing VHF conversations about killer whales. We nearly circumnavigated Discovery Island E of Victoria before joining a group of about 7 transients. They proceeded northward in Haro Strait on the western side and we monitored them and the surrounding whale watch fleet with the array. We didn’t hear any calls or clicks (but weren’t listening carefully all the time). The session was recorded, however, to the tune of about 1.2 Gb of data. Just north of Kelp Reef we turned and headed towards the south end of San Juan Island. We knew the southern residents were exiting the Sound around 130pm and our calculations indicated we might meet them near Salmon Bank. It was nearly dark when we finally pulled into Mackaye Harbor. Little did we know that the orcas were likely just a few miles to the south of us at that point!

Week 3 on the boat and evaluations: official, off the record, of the program and personal

9/29/07
I’m writing this blog entry on my laptop at 6:45 PM, planning to post it when I get back to land tomorrow, which I have to admit is an event I have been looking forward to almost ever since getting onto the boat last Sunday. This was a pretty terrible week for me. The weather has become much colder and the seas have been a lot rougher. We did a good deal of sailing, which got me feeling pretty sick a couple of times. Today was the wildest day but I was not as bad as I was yesterday, maybe because it wasn’t necessary to be outside as much. Yesterday I felt so terrible, both physically sick as well as emotionally shattered that I took Ash up on her advice and went to lie down for half an hour, something that I am usually very nervous and reluctant about doing. Today I took my turn at the helm for a while, during which time I peaked at about 8.4 knots and Todd announced that I had broken the record for electricity generation, at 10.1 amps, which made me feel somewhat better about my general ineptitude this week. I think I regressed in pretty much every way that I had started to improve during my second week, and the fourth week is looming in a very threatening way; Val, Scott and Todd keep warning us that these sorts of conditions will be typical, which scares me because I just cannot function well when the weather is like this, and as much as I try I feel so powerless and inadequate.
And we (especially I) really NEED the fourth boat week because in terms of data collection we’ve not done very well this week at all. I’d say that yesterday was really our one data-day of any real substance, when we were chasing whales literally from morning till night, with some great vocalization recordings and photographs to show for it. But for me personally this was almost a lost week; I got no boat noise recordings at all. I had been hoping to switch my focus from individual boats to cumulative vessel noise at this point but there were so few boats on the days that we deployed that it was pointless to do so. There were a couple of instances at which we had really loud tankers thousands of meters away, I’m not sure if I’ll be able to use those, but that wasn’t even what I was looking for. From another angle, let’s face it, as far as policy, it’s a pretty long shot that we could try to get tankers to install quieter engine technologies; I think they’re even exempt from some regulations. Of course the huge shipping industry and the industries that use them (like petroleum) gets off easy, money talks! But anyway, venting about environmental injustice aside, as I was saying, this was a lost data week for me. We did some sound propagation tests on Tuesday, but when I tried to use the files from the orange box, and then from the blue box, to come up with a transmission loss rate, the numbers were a mess. Val helped me see that if I looked at the second number and the last number, the rate was almost perfect, -19.2 (with the theoretical ideal of -20). But I quickly pointed out, those are just two points! That’s not reliable! And Val jokingly called me a pill and said I should be excited about it, but then later admitted that I was right, that if the points between caused problems the test would have to be redone. I mean, that’s something that CAN theoretically be left to the last week because it’s just one number and I can calculate the source level with a stand-in for now, but I’d just really like to know what the REAL source levels are! (Also, what if my retest still stinks? Then what?) My lack of patience and non-stop worrying clearly make me better-suited for policy rather than scientific research. On the bright side (a very small one) Sam has been able to localize some calls, and the calls from yesterday really seem like they’ll be localizable (not a word, I know), so I can at least start working on orca source power density levels this week. Val teased me with the glass half-empty, glass half-full cliché. I’m not usually such a pessimist, but in science I definitely am, and have been every other time that I’ve worked in science research. Another reason science is not the right field for me.
In other interesting news, we had Scott on the boat with us starting Wednesday, we skipped the whale museum talk on Wednesday in favor of dinner at FHL (which was really nice because we got 6 full hours on land and showers to boot), and this was our week of program/peer evaluations as well as our preliminary sailing assessments. Val had to leave yesterday for a personal engagement and Scott has been filling in for him. He brought the program evaluations aboard, and it was supposed to be anonymous but I handed mine in first, so my identity was hardly a secret. I just hope that my comments will be considered helpful and that nothing was taken offensively. My peer evaluations, as it turned out, I had to redo when I learned that my actual comments would be read by the people they were written for. I didn’t write anything awful, but there are different ways of conveying opinions, and my initial form of expression was not what I would have wanted read. I think that you just instinctively try to use more tact when you speak directly to a person, and let’s face it, anonymous? We all have unique ways of speaking so I’ll be able to guess pretty well who says what about me, as others could guess which comments were mine. I really don’t like the fact that we’re seeing what we wrote about each other, I feel like the self-censorship for tact is not the most effective way of getting honest assessments across.
Earlier this week we had Dr. Marla Holt with us. She was very helpful to some of us, including me, she gave me some good feedback on the Erbe paper I’ve been reading a lot and she helped point me in the direction of key concepts. More generally she was also very good to talk to about graduate school admissions, taking time off beforehand, etc. I also talked to Shannon a lot this week about related questions, and particularly about her evaluation of the Beam Reach program itself and how it’s been run. The truth is that after 6 weeks here, I can honestly say that I probably wouldn’t have applied if I knew beforehand everything how everything would actually turn out. Now that I’m here I’m focused on doing as well as I can, but I’m not sure if this was an appropriate decision for me because I’m not planning to go into marine science, or even specifically marine policy, and I never had any interest in sailing, and for everyone else at least one if not both of these elements was a major point. There are other strong positives about this program that I can appreciate. I just wonder if I might not have been able to better use my time these 10 weeks otherwise. Then again, I’ve done a lot of thinking and living and the experiences I’ve had already have really helped me focus my future plans. At the end of the day, I came here planning to make the best of the opportunity that I could, and that is something that I am still able to do and am striving towards. Whether positive or negative, the program has really highlighted a lot of my weaknesses, my strengths don’t seem to help me much here. On the one hand this can help to focus me further, on the other…some of my limitations make me feel kind of helpless and almost dysfunctional. They are certainly hurting my overall performance in Beam Reach.
This has been a long and rather chaotic entry (more reflective of my thought process than of any attempt at organization). I apologize if this has caused any frustration or confusion for anyone who may have read it.

Rainy Roche changeover

Sunday, September 30, 2007

 

We woke up at Garrison Bay to a drizzly, windy, grey morning.  After breakfast, we lifted anchor and headed over to Roche for the changeover, while we completed our chores.  At Roche, we cleaned the boat, finalized data entry onto the boat’s hard drive, and packed up.  We had a quick, early lunch before the other group arrived.  While the instructors met, the students discussed data collection and potential overlap in projects.  Then, Scott and Jason led a discussion on transportation and sustainability.  Afterwards, Val’s group headed back to the labs while Jason’s group got dinner ready.  We pulled away from the docks at Roche before 1800 and anchored out in the harbor.  Shannon and Jason read proposals, while Kenna, Elise and Liz read the chosen article for this weeks journal club.  Wes continued to localize calls and analyze data, and Heather caught up on some rest.

Oil and swell don't go well

Saturday, September 29, 2007

We woke up at Snug Harbor to oatmeal for breakfast and a full holding tank to pump out.  After chores and cooling the fridge, we headed to Roche where we emptied the holding tank, topped off the water tank, stocked up on a few essential items (i.e. cocoa), got our espresso fixes, and posted postcards to lucky, lucky recipients.  We had our voyage planning in the cockpit as we left Roche.  Anne informed us that we were under a gale warning for the weekend, with winds predicted up to 30 knots.  A superpod was reported southwest of Victoria heading west, so the group decided to motor sail south for a few hours and see what the weather and whales were doing after lunch.  Alex and Anne prepared quesadillas for lunch and heated up leftover stew from last night.  Before 1400, the wind had picked up and the pager informed us that they weren’t going to be sending out anymore messages.  After a few unsuccessful phone calls to try to find out more about whale whereabouts, the group decided that whales weren’t happening today and the seas weren’t suited for studying.  We turned around and headed back to Garrison Bay to take shelter from the storm.  Anne and Tim did some dinghy driving training, Alex plotted a graph of VATO’s water usage, and Ash caught up with the pager data.  Todd passed out the sail assessment test, Scott planned our Sunday turnover, and Shannon wrote this.  As the students tried to catch up on entering data, Scott and Shannon prepared chili and cornbread with cheese and sour cream on the side, because as Tim declared earlier today, “oil and swell don’t go well.”

Wild wind & water work

It’s a rare and exhilarating experience to lie at anchor with steady 35 knot winds howling through the rigging. Gato Verde is galloping on her anchor bridle tonight. Each gust makes the whole boat shudder. Last night the aerial soundscape was geese honking, great blue herons squawking, and tiny fish leaping. Tonight it is all elemental: moaning and whistling of wind over wire, lapping waves, rattling ports, and the creaking of a thousand stowed items jostled by the boats vibrations.

Today was a windy day, with the orcas lingering in the Strait of Juan de Fuca — just beyond our listening range. We made an effort to be at the right place at the right time, but didn’t get lucky like yesterday. Instead, we had a lot of good sailing and even managed to generate some electricity by using the props to slow ourselves down as we ran with the wind.

Alex holds the record for generating a peak current of 10.6 amps at 52 volts on a single motor! That’s a peak power generation of about 500 watts. I was thinking about how to put that in perspective this evening at anchor. Normally, I say use incandescent light bulbs (100W say) or toasters (1kW) and hair dryers (2kW) as references.

But I want to make an intuitive, tangible connection between food (which powers us) and green power on the Gato Verde, like wind/water power. Luckily, as Anne prepared ocean algae pudding (wonderfully accurate texture), Ash mentioned that sugar has an energy density of 16.5 kJ/g. My Treo informs me that chocolate packs 18.5 MJ/kg, while biodiesel offers 41.2 MJ/kg.

Since a watt is just a rate of energy flow equivalent to joules/second, Alex was generating 500 J/s. To get an equivalent supply rate of energy, you could eat 2.7 g of chocolate in 100 seconds, or burn 1.2 g of biodiesel in 100 seconds.

I also like to mention Greg Lemond on a hill climb in the Tour du France as one of the few humans who can generate 700W for extended periods. At rest, humans need about 100W to keep warm and happy. That range is confirmed by the NOLS Cookery book on board that says easy going sailors in warm climates should eat 2500 kcal per day and active, cold weather sailors should eat more like 5000 kcal (5000 “food” Calories). Averaged over 24 hours (86,400 seconds) and knowing there are 3.8 J/calorie, the NOLS rations are meant to supply 110 – 220 watts. This implies that it would take 2-4 of us well-fed humans pulling pretty hard to match the power of the wind.

Whale soup

Orcas resting at sunset

Friday, September 28, 2007

We woke up at Snug harbor and Leslie rang to tell us that she could hear the whales off Lime Kiln, so we lifted anchor right after breakfast and put off our morning chores until later. We spent most of the morning chasing the whales—writing down pager information, listening to the radio, and making phone calls to try to figure out which way they were headed.

Shannon and Ash heated up left over lasagna and bread pudding for lunch, as we made our way to Hein Bank, where there were reports of J, K, and L pods. We deployed the hydrophone array and the high frequency hydrophone and began our recording attempts for the day. We switched direction a number of times, alternating between pure sailing and motor sailing, as we tried to record calls, clicks, and whistles of individuals. A rope got momentarily wrapped around the starboard prop, as Scott and Tim were trying to deploy the high frequency. We sailed back to the west coast of San Juan Island and were going to head back to Snug Harbor early, when we saw J1 and a couple of other whales. Shelmar, a research vessel collecting the breath of killer whales with petri dishes suction cupped to a 24 ft pole in order to analyze bacteria, was also there. Tim took advantage of the opportunity to deploy a buoy and record drive-by’s, but the clicks and calls of nearby whales drowned out their jet engines. So, Anne once again attempted to deploy the hydrophone array vertically. A tanker was passing by, so we aren’t sure what the sound files will look like. Just as we were getting ready to call it a day, a large number of whales resting and slowly traveling in a line through the sunset approached us, followed afterwards by a lone minke whale. We finally pulled back into Snug about 8 pm after traveling over 37 miles today.

Wandering whales

What a classic field day. Leslie relayed news that she was hearing calls early in the day. But as we caught up with them, muliple factors conspired to deny us high-quality data (in the way they often do in field research). First we would be near a whale, but it wouldn’t be vocalizing. Then a noisy ship would approach as the orcas started to call. When the ship would pass and the calls would be frequent, the wind would rise, blow us down wind, and cause the cables to “thrum.” We’d trouble shoot the flow noise and be ready to record, when the waves would build extremely. Suddenly, enforcement agents (Washington Department of Fish and Wildlife) would swing over to ask us some questions — distracting us from our quarry.

It was a very long day, but in the end we all gained some new insights. We were lucky the killer whales turned back when it seemed they were headed out to the big ocean! And then we were treated to the near-silent underwater noise from Bob McLaughlin’s jet-drive powered boat, quite a few nice calls and clicks, and stunning silhouettes of a resting (quiet) pod traveling up Haro Strait on the flood tide.

Mid-program reflections

Today I began my second week with the fall 2007 Beam Reach class. It feels like a real privilege for this dad to again have a chance to go to sea, particularly with this group, these technologies, and the winds building for good sailing as October looms. The killer whales have been doing some exciting things this week — superpods and ceremonies — and with luck we’ll have another chance to listen to them and the boats in their environment.

My main goal this week is to give everyone a few opportunities to reflect on the program, teachers, and students and provide some feedback. With some guidance, we can improve the next 4-5 weeks, as well as future programs. I’ll also try help everyone acquire, manage, and process their data.

The highlights today were marveling at the challenge of planning a day of field work and the calming beauty of a sunset seascape. Ash, Alex, Anne, Tim and Sam did a valiant job of deciding what to do when J+K pod headed up toward the Fraser and L pod evanesced along the southwest side of San Juan Island. With a foreboding forecast (30 knots out of the west), substantial tides changing direction at mid-day, and the lure of novel anchorages, it was tough call. But we ultimately headed south and nearly overlapped with L pod.

The reprieves were some fun sailing, the sunset, lasagna, and the prospect of an evening spent sifting through the GREAT data we have already acquired. The pace is always blistering up here, but the challenges are refreshing and the insights come fast.

It was a treat today to read in Fred Felleman’s thesis that the southern residents “change their direction of travel within an hour of slack current 7 times more frequently than would be expected by chance,” and to then observe L-pod head north against the ebb in the morning (max ~8am), north as the flow reversed ~2pm, and then (within an hour!) south as the flood current strengthened. There is clearly more work to be done on what guides their behavior and how the fish in Haro Strait react to the local oceanography. In fact, looking at the pager record, it seems that there are data for examining at least the relationship between orca travel direction and the local currents.
