Ship name (ship code)

RRS Challenger (74CH)

Cruise identifier

CH55

Cruise period

1989-06-24 — 1989-07-07

Status

Completed

Port of departure

Great Yarmouth, United Kingdom

Port of return

Great Yarmouth, United Kingdom

Purpose

Research

Objectives

To determine the seasonal cycle of all the major oceanographic variables in the North Sea.
This info will form a unique data set on seasonal changes in an archetypal shelf sea which will be used as a basis for initialising and testing models of vertical exchange, horizontal transport and the seasonal cycle of production and nutrient regeneration. These models represent essential intermediate goals in the long term development of skillful models describing the fate of pollutants which are released into the North Sea.
