BODC Cruise Metadata Report for RRS Discovery (74E3) cruise D61

Introduction

This report collates information from the BODC cruise inventory and oceanographic databases. It presents

Cruise Inventory Information

Long name RRS Discovery (74E3) cruise D61
Short name D61
Objectives and Narrative To investigate the rates of change in a community structure and the growth and development rates of the mesopelagic fauna south of the Bay of Biscay. The cruise was timed to coincide with the time of the spring bloom when the greatest rates of change in community structure and in growth rates might be expected to occur.

Bottom sampling was carried out on Galicia Bank.

Experiments were carried out on the microstructure of the surface 100m of fluorescence, nutrients, temperature and salinity. Several very deep tows were made down to 4000m with the combination net. Samples were also collected for the SMBA, and material was deep frozen for dry weight and biochemical determination.
