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)
