Hydrophones
From Beam Reach Wiki
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)
- Uncalibrated
- ITCs (towed single and in Orcasound array)
- other CRTs
- salvaged Navy sonobuoy single elements
- miscellaneous single elements (donated by Mike Dougherty)
- etc...
- Calibrated (see response curves below)
- Interoceans (used courtesy Colorado College)
- C54XRS (from Cetacean Research Technologies)
- Reson TC4032 (deployed 2009 at Lime Kiln with The Whale Museum)
- Uncalibrated
Calibrated response curves (all by Joe Olson at Keyport facility):
(one of Marla Holt's, but same model as those used by Beam Reach) Spec sheet for Reson TC4032)
Wish list of other hydrophones
(Will review above as we try these out...)
- Hydrophone comparison matrix
- Naxys eHyd digital hydrophone (Expensive! APL paid ~$13k in ~2007/8)
