Purpose

Research

Objectives

1. To make underway measurements of air-sea fluxes, surface-sampled variables (temperature, salinity, transmittance, fluoresence, irradiances) and Acoustic Doppler Current Profiles, around the set "survey" track covering the southern North Sea.
2. To make CTD stations (recording temperature, conductivity for salinity, transmittance, fluoresence, dissolved oxygen, up- and down-welling, irradiance as functions of depth) at 120 sites along the track, also taking water samples for calibration measurements and nutrients.
3. To deploy a current meter mooring at site G and an ADCP and thermistor chain mooring at H.
4. To take multiple cores from sites 1 to 6 and carry out benthic flux and DMS analyses thereon.
5. To deploy current-meter/transmissometer/fluorometer moorings at positions A, B, C and D north of the Rhine outflow, and met. buoy, waverider and "eta" (near-surface current) moorings at position E between A-D.
6. To recover and deploy ADCP and P/T/C/transmissometer moorings in the Dover Strait.
