Resource Management

Resource Management
On a daily basis the average American wakes up, brushes their teeth, showers, flushes the toilet, and drives to work. During their lunch break they usually drive somewhere to get a meal, and drive back to work. After work they drive home, make dinner, maybe watch some television or read a book, and then go to bed.
While living on the Gato Verde for about three weeks, we learned a lot about the resources we use on a daily basis and some of the thing we take for granted, like water. Every day we measured how much water was used and calculated the amount of water we used per person per day. On average we had 6 people living on a 42 foot catamaran using 18 gallons per day, or approximately 3gallons/person/day. I assumed this was a significant amount of water to be using, considering it was only used to wash dishes by hand, brush teeth, flush the toilet in the head, and occasionally wash hair. After doing a bit of research I was surprised to learn that the average American per day uses 80-100 gallons of water. Most of this water is used for bathing/showering and flushing a toilet. With such a large amount of water being used every day, by each person, it is astonishing that many of us never think about the amount of water we are using, and where it is coming from. Because water is so accessible to most Americans, it seems that we often forget not only the amount of water that we are using daily, but also the other resources being used so that we can have water at the turn of a faucet.
While it is nice to have the convenience of water at our finger tips, it is important to remember that clean, useable water is not easy to acquire in many parts of the world, and there are many costs associated with using such a large amount of water. Next time you flush your toilet, think about how much water was just use, and how many chemicals will be needed to treat the waste water before it is sent back out into the environment.

Ignorance is Misery

Foraging Behavior?

While there is a lot of information that we do know about the southern resident killer whales, there is so much information that still remains a mystery about these great predators. It has been established that the southern resident killer whales mainly eat Chinook salmon, which makes up 65% of their diet. Research has also shown that Chinook salmon within the home range of the southern resident killer whales are also endangered (Hanson, 2007). In addition to knowing their diet; their family structure, life span, age of sexual maturity, and vocalizations used by these predators are known as well. With all of the knowledge we do have about the southern resident killer whales, there are a lot of things that we can only speculate about. One thing that remains unclear is what the vocalizations of these whales mean.
While on the Gato Verde I focused on one specific question, which was – can killer whale click rates tell us anything about foraging behavior? Researchers have found in several species of toothed whales that there is a relationship between acoustics and foraging behaviors (Simon, 2007). Because so much of a killer whales activities take place under water where visability s limited, this question was particularly hard to answer.
I was unable to find a direct correlation between foraging and click rates from the data I collected, however I am still interested in further exploring this question. Further research on this topic would perhaps give me a more definitive answer, and it would be useful in determining what activities are taking place in their underwater habitat. While the answers I found through my own project were not entirely satisfactory, this project did heighten my curiosities about what the clicks produced by killer whales could be telling us. I would recommend that others explore this topic as well, so that one day we will have a definite answer to what their vocalizations mean.

One fish, two fish. . . No more fish?

Concerns about overfishing are a pressing issue. Technological advances, have made fishing industries much more efficient. Fish are caught at greater depths, and in much larger numbers. Some scientists have estimated that as much as 90% of large predatory fish including sharks, swordfish, and cod have been removed from the oceans of the world . With so many large predatory fish having been removed from the ocean it may seem that there are plenty of other fish in the sea, however this is untrue for a growing number of fish populations. Other factors, including pollution, fishing methods, and habitat destruction contribute to the decline of many fish populations, including Chinook salmon.

As we have learned, Chinook are the preferred prey of the endangered southern resident killer whales. These salmon are also listed as endangered. Habitat degredation, genetic and ecological impacts from hatchery production, and impacts from hydropower are factors that put these fish at risk. While Chinook salmon make up 65 % of the southern resident killer whales diet, and are of upmost importance to this population of killer whales, they are also consumed by many other marine animals. As specific fish populations become threatened or endangered, so do the predators that depend on them as a food source.

Understanding relationships between predators and their prey is crucial to maintaining, and sustaining the environment in which all living creatures share. Establishing the importance of all members contributing to an ecosystem further emphasizes the importance of practicing sustainability. It is important to remember that the environment in which we live is delicate and can be manipulated easily. It is up to all members of society to establish methods for fishing that will not devastate the environment in which they live, and share.

A Beam Reach First

As all the 112 Beam Reach students (Sharon, Laura, Hayley, and Charla) can recall the phrase we heard the most was “this never happens” or “this is a first”.  After hearing it a few times we decided to keep track of all the so called “firsts” for Beam Reach.

  1. Seeing a fire truck and an ambulance zooming through campus – “This never happens at Friday Harbor Labs!”
  2. First year observing at Lime Kiln – “You are the first Beam Reach class to be able to use the Lime Kiln as a research base… so now you get to clean the acoustic shed, YEAH!”
  3. Residing in T2 (with carpet) compared to S1 – “This is a first, we have only had S1 in the past…and there is carpet!”
  4. Most organized and clean group of students – “Your dishes are so organized all the time; this is a first for Beam Reach.”
  5. Most whale days – “You guys are so lucky this never happens.”

    Breaching Southern Resident

  6. Most Dall’s porpoise off the bow – “It’s rare to NOT see Dall’s but never this much.”
  7. First Canadian – “Charla is the first Canadian to be a part of Beam Reach – CONGRATS!”
  8. First conference (Salish Sea Ecosystem Conference) – “This is the first time Beam Reach is going to a conference and presenting posters”
  9. Lunch with John Ford – “I bet this is a first for Beam Reach, lunch with a science celebrity… John Ford!”
  10. Most rainbows (single and double) – “Want another Beam Reach first… the most rainbows!”

Students collecting data at Lime Kiln








After an eventful quarter at sea collecting data we finally had the opportunity to analyze it and see our results.  We presented posters at the Salish Sea Ecosystem Conference in Vancouver, Canada.  We, the students, presented posters, talked with many scientists, and sat in on 3 days of presentations.  We were all extremely blessed to have received this opportunity as it has helped in networking and giving us a glimpse in the scientific world.  We will now all go our separate ways, but we will never forget the Beam Reach experience!

Beam Reach at Sea: Research on the Gato Verde

All the times we missed the orcas passing the Lime Kiln during our land-based research were about to be made up for…

Once we were aboard our catamaran home, our lives could basically revolve around the movement of the orcas, and it didn’t take long for that to begin. Since we started taking data on the whales right from day one, we had to take what we had learnt at the Lime Kiln and adapt quickly to data recording at sea.

“Permission to Deploy the Array”:

Once the whales were around us, we would deploy a four hydrophone array from the back of the boat and start recording. Laura listened to the calls and clicks being recorded in one minute time segments and recorded what she could hear on a phonation sheet so we could go back and listen to the best recordings afterwards. We also played the hydrophones through the speakers throughout the catamaran, so even those of us not working on the acoustics could have the full effect while we were with the whales.

“Two whales, 12 o’clock, 200 meters, traveling North!”:

Sharon and I were on behaviour lookout. The idea was to call out every whale we saw with a clock bearing, a distance, and what activity they were doing, while Hayley wrote all this information down on a behaviour sheet. We were also specifically recording surface active behaviours (such as tail slaps and breaches) and foraging behaviour for our own projects. Sounds simple enough, but when you have anywhere from 5 to 50 whales in sight, 360 degrees around the boat, things got pretty crazy (but crazy in the best way possible, this is what we were here for!).









An orca breaching (left) and J26 – “Mike” swimming past the Gato Verde (right) during our data collection.


Since Beam Reach 112 had some of the most orca encounters while out on the water, this routine was continuously practiced and fine tuned, but every so often there were days without orcas where we could experiences some other aspects of life at sea.


While the orcas are away:

One of our other main focuses while living at sea was learning about sailing. We had lessons beginning with all the basic parts of a sail boat, and progressing through raising the sails, choosing an appropriate sailing course, steering, tacking and jibing, and learning the right of way rules. It was great experience going through all the steps required in order to sail, and to help eachother learn along the way. We even had the opportunity to sail with some near gale-force gusts making it all the more exciting.

Preparing to raise the main sail

We also quite often had some other playful cetaceans visit us while the orcas were out at sea. Dall’s porpoises would bow-ride infront of us, most often near the Lime Kiln. We would lie on the front on the boat and watch them swimming just a couple feet below us. Some would even turn on their sides to get a better look at us and then come up to give us a splash, seemingly on purpose. We even thought we could hear them clicking on our “listening hydrophone” we had deployed one day as they approached our stationary boat.

Other research we conducted while the orcas were away included CTD casts, which took the whole team to lower the CTD (an instrument used to obtain a depth profile of temperature, salinity, and various other water measurements) 60 meters into the water, and then use a winch to crank it back onto the boat. I also fished for salmon and analyzed fish finder data from the boat for my project while the orcas we away, and had great success doing so!

Killer whale sessions at the Salish Sea Ecosystem Conference

Lime Kiln noise budget

Ships dominate Lime Kiln noise budget

The whole Beam Reach crew was represented today in two killer whale sessions at the Salish Sea Ecosystem Conference. The sessions were convened by Scott and involved a great line-up of experts(see list of presenters below) talking about recent results from from non/invasive studies of southern resident killer whales (SRKWs).

Val gave a talk on underwater noise in the SRKW critical habitat and estimated that ships dominate the noise budget 83% of time (see plot at right).  This works out to a long-term average of nearly a ship per hour!

Charla Basran with her poster

Jason gave a talk on compensation in ship noise.  Andrea Buckman — one of our visiting experts this fall and last spring — spoke about the variable condition of chinook salmon.  Robin, Laura, Sharon, Charla, and Hayley attended the sessions, and then continued to share and display their posters — now available on-line as PDFs — listed below.

Student posters:

108 – Sharon Bannick – Movement and Surface Active Behavior of SRKWs in Response to Current Velocity and Salinity

109 – Charla Basran: Correlating SRKW Sightings with Pacific Salmon Densities

110 – Hayley Dorrance: Can clicks tell us anything about the foraging behavior of SRKWs?

112 – Laura Moe: Variations in S6, S10, and S19 calls in SRKWs

Session descriptions and speaker lists:

The killer whales of the Salish Sea are listed as threatened or endangered in both the U.S. and Canada. As the scientific and stewardship communities continue to weigh the costs and benefits of invasive methods like satellite tagging, there is a pressing need to exchange all available information from non-invasive research techniques. There are also renewed efforts on both sides of the border to integrate the management of killer whales and the listed species, like Chinook salmon, upon which they prey. 2011 has also brought Federal regulation of orca-boat interactions in the U.S. This session will survey recent scientific results, with an emphasis on less-invasive techniques and new implications for transboundary killer whale management.

Beam Reach on Land: Research at the Lime Kiln

Learning about the ecosystem an organism belongs to is often just as important as learning about the organism itself, so that’s what Beam Reach 112 set out to do for the first few weeks on land. We were fortunate enough to be able to set up our land based research at the Lime Kiln lighthouse where the orcas are seen frequently (usually!). Though the orcas managed to elude us the majority of the time we were at the lighthouse, we had no shortage of research we could do.

Marine Mammal and Bird Observing:

Each day at the lighthouse, one person was on observation. For 45 minutes at a time, every bird and mammal spotted was recorded. Seagulls, Cormorants, Murres, Dall’s porpoises, Harbour porpoises, and playful seals were regulars at the lighthouse on pretty much a daily basis.








Harbour porpoise and a peeking seal observed from the platform infront of the Lime Kiln lighthouse.


Underwater Camera Monitoring:

An underwater splashcam was installed directly infront of the lighthouse with the first hydrophone and the, also newly installed, CPODs (for detecting dolphin and porpoise clicks) in view. One person’s duty was to record everything that swam infront of the splashcam on paper and as 10 minute video recordings. We often had kelp greenlings and rockfish hanging around in view, taking the occasional nap ontop of the CPODs, or swimming up to give the camera a big kiss. We also got footage of the occasional large lingcod, seals swimming past, and schools of salmon swimming north (headed for the Fraser River?).

Water Analysis:

Using a YSI monitor, two people recorded water temperature, salinity, and dissolved oxygen daily. Then they also took a plankton tow and attempted to identify as many species as possible. The average water temperature was 10.85°C, average salinity was 28.95ppt, and average dissolved oxygen was 6.25mg/L. Some of the most commonly identified plankton species were Chaetoceros, Cylindrotheca, and Skeletonema.

When we finally caught the orcas swimming past the lighthouse, we were ready to spring into action. One person started recording and monitoring the hydrophones. Audible calls and clicks were recorded on a phonation sheet so that we could go back and listen to the best times of the audio recordings. The other three of us headed down to the “iron post” infront of the
lighthouse, armed with a behaviour sheet, binoculars, and the camera. The goal was to record clock orientation (to the iron post), travel direction, distance, and any surface active behaviours, and attempt to get as many identification pictures as possible. This information goes into the Beam Reach archives to help with future projects, and can be used to help us confirm localizions of calls from the hydrophone recordings.








Orcas passing by the Lime Kiln lighthouse on September 15, 2011


Our time at the Lime Kiln helped us learn about the “big picture” of all the pieces of the orcas’ environment. Though it was kind of hectic (yet extremely exciting) when we did get to record orca data, it gave us a good introduction to what life on the Gato Verde would be like…

Volunteering for SoundWatch

Through Beam Reach’s Sustainability portion of the program, we (the students) get to choose projects to either educate the public or volunteer our time. One of the projects we all agreed on and decided we must do is volunteer for SoundWatch. SoundWatch is the boat that follows the orcas around and educates the public about the laws pertaining to them.

David scoping for whales

All four of us got our own day to volunteer for SoundWatch. I was the third one to go, and I was ecstatic because I had never experienced the orcas from a boat yet! A man named David Howitt picked me up, and we drove to the other side of the Island to Snug Harbor to meet Tyler, another volunteer. After getting my paperwork all squared away, I hopped in the boat with my mustang suite on (these huge orange suites that are very warm PFDs) and we went down to Eagle Point (south of the lighthouse) and found the orcas right away! It was incredibly calm. I was amazed at the amount of fishing boats that were out; I counted 60 from where we were at, and the orcas were right in the middle of them. It was insane! Right away it would’ve already been crazy to try to coax the boaters away from the pod’s path, so we just made sure everyone was stopped so that the orcas could go through. Thankfully they made it out of that mob of vessels safely. Wow, just hearing them breath all around you is breathtaking. It was incredible being out there.

Every half hour it was my job to record where we were (latitude and longitude), how many boats (and types of boats) were present, what the whale’s behavior was, and which pods we were following. Weather was also noted. I was also in charge of giving people a copy of the regulations with this long stick with a little clip. We were lucky, everyone was grateful that we were out there, and treated us well. I guess that doesn’t always happen.

Near the end of the day the whales moved further west, the crowd of boats surrounding them died down. I saw some bull kelp in the water and I thought “I want to try playing one of those…” I’d heard of people being able to play bull kelp, and some even do it to summon the orcas. I’m a music minor, so the idea was hard to pass up! David let me stop for some bull kelp and he cut the end off and made it into a horn! Bull kelp is a long hollow tube that slowly narrows as it gets longer, and it was surprisingly slimy! First David had a go, and being a past horn player himself, I would believe that he could summon the orcas with that sound. Then he let me try, and now I can honestly say I played kelp! Like any brass instrument, I could get a few notes out of the one piece of kelp, and we’d cut it to different sizes to get different sounds.








Not long after that there were only about 3 boats left out there. We did our count, and said goodbye to our black and white friends and called it a day.

Sailing Around Cape Kellett Bluff

Ahoy...Captain Todd

Beam Reach is a program that provides extensive learning opportunities and self discovery for every participating individual.  Each person has their own personal experience, however different from another, and helps to broaden minds and mold a more rounded individual.  Among the many educational opportunities students were educated in sailing around Haro Strait was one of the most enjoyable.  The captain of the beautiful Gato Verde, Todd Shuster taught us the in’s and out’s of sailing.  To understand how “easy” Beam Reachers had it with only 3 sails (screecher, jib, and main sail) we watched an educational video on sailing “Around Cape Horn” made and narrated by Irving Johnson, which inspired the following video.  Once the basics were taught we put our knowledge to the test…

42' catamaran - Gato Verde

On October 10, 2011 each student had a round at being the helmsperson at the Gato Verde.  The helmsperson practiced calling jibes and crashing through the stormy waters off the coast of Kellett Bluff.  Students not driving the catamaran had to focus their concentration on helping the boat jibe.  One student on port and another on starboard when the helmsperson yelled “READY TO JIBE?” they respond “READY”.  The helmsperson, knowing the students were ready yelled “JIBING” and one student would release the jib sheet while the other would pull in the slack on the opposite side of the catamaran.  After jibing the Gato the working crew got to relax and enjoy the experience of sailing around “Cape Kellett Bluff”.  It was safe to say the 30 knot wind gusts made for an eventful and wet sailing experience.  Although the crew was chilled and soaked to the bone, the cargo did arrive safe and dry into Garrison Bay!

First Cruise on the Gato Verde

My first reaction to the Gato Verde was, “Wow. It’s roomy!” We have it really nice on this French vessel. It was built in 1998 and Captain Todd said the model type hadn’t changed much since it was built, and it felt clean and new. I first looked around the boat, and there are 4 double cabins, and 2 single cabins up in front. The four of us have two double cabins on one of the catamaran’s hulls. The doors are made out of a type of red wood, and the accommodations feel almost hotel-like compared to what I was expecting! My roommate and I share a bed, and again I was amazed at the amount of space we had. I initially imagined being smashed together in a twin size cot. I guess my imagination goes a bit far when they said we’d have tight accommodations! In the middle of the two hulls is the actual cabin, where the kitchen/living room is which consists of a round table with booth-like chairs that also act as storage for our food (that we got the luxury of picking out ourselves instead of going through NOLS). This was our spot during the evenings of entering data that we had gotten throughout the day, or paying catch-up from previous days! After hauling stuff onto the boat, we were off! As we were going to our port, we just explored the boat, and went outside on the “trampoline” which was a mesh that you could sit on and really feel like you were as close to the ocean as you could possibly be without jumping in!


The very first full day on the boat we got to encounter the whales by salmon bank! So we headed out straight away to go catch them We learned on the fly as we set in the hydrophones and scrambled for data sheets that we’d printed off for our specific projects. It was so amazing: I heard their calls as I heard them come up breathing all around us. Sound travels so brilliantly across the water, you can hear them breathe from pretty far away and still feel like they’re so close. My job was to sit with headphones on until they made calls or clicked and note when it happened, and what type of call it was. The sun was WARM on my back; another luxury I hadn’t planned on having while I was on the boat. We collected data for over three hours! And it felt like 30 minutes. We turned in to Snug Harbor and started looking at the photos at the end of the day. Both Charla and I made the same conclusion: we saw J16 (Slick) and J27 (Blackberry)!


We saw whales every day for the first three days of our trip, still learning how to do things on the go. Our first non-whale day was Charla’s birthday, the 23rd, and as close as the trampoline gets you to the water, we decided it wasn’t enough. After a CTD cast, Charla announced, “Okay, we’re jumpin in!” What peer pressure! I can’t say no to such a simple birthday wish, despite my horror to the cold rush that was about to come. But it was such a beautiful warm day! We threw our suits on and it was actually really comfortable out in the sun. And we jumped in! Into 700 feet of water. I felt so small. We swam underneath the Gato, and it was actually quite refreshing after not showering for 5 days.

We were locked into Snug Harbor for the majority of the next day due to fog, but when we finally got out, the most incredible thing happened: for the first time of the trip, we got to experience dall’s porpoises riding our bow! We all laid on our bellies at the end of the trampoline and looked over the bow; if I wanted to, I felt like I could reach down and run my hand across one. You could tell that they were just as curious about us as we were about them, because every so often they’d lean far over on their sides and take a look at us. It was a pleasant end to a relatively uneventful day.

The next couple of days, instead of being trapped by fog, we were trapped by 40 knot winds. We had sailing lessons during this time from Captain Todd (just white-board stuff of course). In the afternoon, we heard the whales were right outside the harbor, and we declared that the wind died down well enough for us to go out and take a peak! For the first time of the trip, all of my rain gear went on and we got to enjoy the whales for about a half hour. I couldn’t deploy the hydrophones unfortunately, because the waves were too high. We went to Garrison Bay for a while because it’s more sheltered than Snug for the winds that weren’t predicted to let up any time soon.

The next day, as predicted, we had 40-knot winds again, and we experienced it right in the harbor! Whales were right in Haro Straight next to us, but we were stuck. By the evening we all went to land and walked for a while at English Camp for some much needed exercise! We also watched Robin’s favorite movie in the world: Life Aquatic.

The next couple of days were data days! We ended up being able to catch the whales right away in the morning! It was great getting back into the groove after a few storm days of storm. I guess we’re really lucky, EVERY day that we’ve had good weather we’ve been able to be with the whales for a while! I think I got some amazing recordings from L pod today, and we’ve been seeing mostly J’s and K’s throughout the week, so this was really exciting for me! I felt like it was like a one-time deal, and the adrenaline kicked in. Such precious data! It was a perfect closing to our first cruise. The final day I went on Soundwatch with Sharon before going back to the labs. Seven Days out of the eleven we got to be with our black and white friends, and I never felt so lucky.
