Ship name (ship code)

RRS Challenger (74CH)

Cruise identifier

CH28

Cruise period

1988-04-29 — 1988-05-14

Status

Completed

Port of departure

Great Yarmouth, United Kingdom

Port of return

Great Yarmouth, United Kingdom

Purpose

Research

Objectives

1. To test the proposed cruise track.
2. Along the track to make continuous measurements of:
(a) Sea surface temperature, conductivitiy, transmittance, fluorescence , dissolved oxygen and up- and down-welling irradiance.
(b) To obtain water samples with a rosette sampler for calibration of the CTD sensors and for nutrient and trace metals analysis.
3. To obtain sufficient cores to enable the benthic fluxes experiment to select six representative sites where measurements will be made during the survey cruises.
4. To deploy and recover four moorings at 52 30N 2 25E.
5. To test the instrumentation, techniques and methods to be used during the survey cruises, including the shipborne computer.
6. To train people to operate the equipment; a mid-cruise port call at Tynemouth will enable the exchange of personnel.
7. To extend the survey data set (August 1988 - October 1989) by obtaining data in May 1988.
