1988-10-01 — 1988-10-14

Status

Completed

Port of departure

Great Yarmouth, United Kingdom

Port of return

Great Yarmouth, United Kingdom

Purpose

Research

Objectives

1. To make underway measurements of air/sea fluxes, surface-sampled variables (temperature, salinity, transmittance, fluorescence, irradiances) and Acoustic Doppler current profiles, around a set track covering the southern North Sea.
2. To make CTD stations (recording temperature, conductivity for salinity, transmittance, fluorescence, dissolved oxygen and up and down-welling irradiance as functions of depth) at 120 sites along the track, also taking water samples for calibration and productivity measurements.
3. To take zooplankton samples at about 60 of the CTD sites.
4. To recover and redeploy current meter moorings at sites A, B, C, D, E and F.
5. To recover and redeploy thermistor chain moorings at sites A, B, C and D (if temperature structure warrants redeployment at D).
6. To take multiple cores from sites 1 to 6 and carry out benthic flux analyses thereon.
