Abstract

A towed boundary layer instrument package (BLIP) has been developed to study the dynamics of near-bottom flows. The package consists of a downward-looking 150 kHz acoustic Doppler current profiler (ADCP) and a Neil Brown MkIV conductivity-temperature-depth (CTD) instrument mounted on a modified General Oceanics 12-place Rosette frame. BLIP is operated in towed yo-yo mode--cyclicly raised and lowered from near the bottom to several hundred meters off the bottom while a forward speed of approximately one knot is maintained. The ADCP allows the velocity and tracer fields to be sampled simultaneously. The design and operational considerations made during development of the package, and an initial assessment of package performance based on data obtained during a recent field expedition are discussed.
