Testing of Trawl Resistant Bottom Frames, 1 August 2000
Trawl resistant bottom frames manufactured by
Flotation Technologies, each equipped with
an AM-200 and an AMTR-200 acoustic release from
EdgeTech, were tested
in upper Penobscot Bay on the R/V Argo Maine. Two small bottom frames (AL-200) and one
large bottom frame (AL-200RA) were deployed several times in depths of approximately 50-70
meters. The frames were released at the
surface and were allowed to settle before the acoustic releases were fired.
On three deployments, a
Seabird SBE-19 CTD data logger was clamped to the cage
to measure the descent rate (one on a small frame
and two on the larger frame).
