Summary of measurements |
- -High-resolution bathymetry using pole-mounted EM3002 echosounder on starboard (leg 1).
-Current measured using 75-kHz shipboard ADCP, current measured by 600k-kHz pole-mounted ADCP (leg 1). -300 kHz ADCP + multi-parameter EXO probe deployed on seafloor at depth of 30 metres (leg 1), then searching for the mooring after it was lost (leg 1), EK60 4-frequency (38, 70, 120, 220 kHz) echosounders (leg 2). -Turbidity sensor (YSI), in situ laser granulometer (LISST) (leg 1), TSG (temperature and salinity) (legs 1 and 2). -Rosette stations with sampling bottles, CTD 911+ probe (temperature, salinity, oxygen, fluorimeter) + TAPS plankton profiler + AQUASCAT sub-bottom profiler (legs 1 and 2). -Granulometry data (LISST 100) + sound velocity profiler (SVP 15) + water samples for filtration (measuring turbidity) (leg 1). -Batos weather station: acquisition of meteorological data (sea temperature, air temperature, humidity, barometric pressure, wind speed and direction) (legs 1 and 2). -Laser granulometer, TAPS acoustic profiler, multinet for zooplankton (leg 2), Van Veen grab for sediment samples (legs 1 and 2). -Bottom trawl, pelagic trawl, bottom dredger (leg 2).
