Ziel der Reise / Objectives of Cruise:
Objectives and brief narrative of cruise: As part of the Coastal Ocean Processes (CoOP) project Coastal Ocean Advances in Shelf Transport (COAST), this was the second of two cruises in 2001 to study cross-shelf transport processes in a wind-driven coastal ocean. The project includes field experiments off the Oregon coast and coordinated ocean circulation / ecosystem and atmospheric modeling. We made intensive observations in two regions: one north of Newport (Oregon), in a region of relatively simple topography and one south of Newport centered on Heceta Bank. A variety of instruments were used: a towed, undlating vehicle (SeaSoar) to measure temperature, salinity, microstructure and phytoplankton fluorescence; a shipboard Acoustic Doppler Current Profiler (ADCP) to measure water velocity; a towed, four-frequency acoustics unit (HTI) to detect large ooplankton and larval fish; a multiple net system (MOCNESS) to obtain clean seawater for determination of its iron content. We worked in close coordination with teh R/V Thomas G. Thompson, aboard which other coast scientists conducted vertical profiling.
