Low power, two-channel marine mammal recorder
Abstract
A key goal of our past work, one that was realized, was tight integration between the marine mammal recording hardware and the glider. This tight integration facilitated, for example, the automatic upload of beaked whale detection statistics on a dive-by-dive basis via the glider s Iridium SATCOM link, and automatic blanking of the recorder during times the glider was known to be emitting significant self noise (e.g. when running pump motors). For this work, we propose to design, fabricate and test a third generation PAAM board (hereafter referred to as the PAAM Rev. C board) with the following attributes: based on modern, low power, hardware that is both supportable and sufficiently low power so as to enable multi-month duration, wide-band survey missions; supports streaming, synchronous sampling and storage of two hydrophone channels; supports sampling rates comparable to those used on the previous PAAM boards (order 200,000 Ksps, 16 bit samples) which is tightly integrated with the Seaglider telemetry stream, which can be used in stand-alone (e.g. buoy) systems.
