Beam Reach hydrophones

  • Arrays
    • 4-element linear array (Lab40 model from LabCore Systems, Lon Brockelhurst) Though these are not calibrated, they are the same model as the elements in a similar array that was calibrated by Marla Holt. (Add her calibration curves here?)
    • 8-element beamforming array from Mike Dougherty (not operational)
  • Single hydrophones (this should probably become or be supplemented by a Google spreadsheet)
    • Hydrophones for which we don't have calibration curves
      • ITCs (towed single and in Orcasound array)
      • other CRTs
      • salvaged Navy sonobuoy single elements
      • miscellaneous single elements (donated by Mike Dougherty)
      • etc...
    • Hydrophones for which we have calibration curves
      • Interoceans902e Interoceans (used courtesy Colorado College; calibrated by Joe Olson at Keyport facility)
      • ResonTC4032 Reson TC4032 (deployed 2009 at Lime Kiln with The Whale Museum, Spec sheet for Reson TC4032)
      • LabCore 40 Lab40 (one of Marla Holt's, but same model as those used by Beam Reach; by Joe Olson at Keyport facility)
      • C54XRS C54XRS (from Cetacean Research Technologies; calibrated by Joe Olson at Keyport facility)
      • HTI99HF HTI-99-HF (from High Tech, Inc; calibrated by U.S. Navy in Newport, RI facility; full report as a PDF)
      • HTI99HF SQ-26-08 (from Cetacean Research Technologies web site in 2019)
