BODC Cruise Metadata Report for RRS Discovery (74E3) cruise D92

Introduction

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

Cruise Inventory Information

Long name RRS Discovery (74E3) cruise D92
Short name D92
Objectives and Narrative Primary aims:
1. To collect a comprehensive series of midwater samples throughout the total water column including samples from within 5-20m of the sea bed at two stations at depths of about 2000m and 4000m respectively in the Porcupine Sea Bight region.
2. To collect benthic samples using a variety of samplers at these same stations to complement the midwater sampling so an assessment of the total water column ecosystem could be attempted.
3. Initial midwater studies at 42N 17W for facilitate the designing of the joint biological and physical mesoscale experiment planned for 1980/1.
Secondary aims:
4. To collect a series of oblique samples along 13W and 17W to investigate the possible existence of a zoogeographical boundary between 42N and 50N.
5. To make observations on the physical structure of the water in the Porcupine Sea Bight area.
6. To make studies on the phytoplankton during the cruise by fluorometry, particle-counting and direct study of phytoplankton.
7. To develop the multiple RMT 1+8 system.
8. To use the in situ light meter mounted on the net monitor to study the relationship between light levels and the diurnal migration patters of zooplankton and nekton.
9. To collect a repeat series of hauls at 1000m to investigate a) the patchiness of organisms at such depth and b) whether these organisms undergo diurnal vertical migration.
10. To collect further benthic samples from as many depths as possible between the edge of the continental shelf and the abyssal plain in the Porcupine Sea Bight Area.
