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

Cruise Inventory Information

Long name RRS Discovery (74E3) cruise D21
Short name D21
Objectives and Narrative Objectives

1. Continue investigations into the vertical distribution of zooplankton by a programme of day and night sampling with depth monitored opening/closing nets at a position far enough south to examine a fauna quite distinct from that examined at the Fuerteventura position.
2. Make observations at the Fuerteventura position at a different season of the year.
3. Try to discover the 'whereabouts of the faunal boundary between the 'southern' fauna and that found at Fuerteventura.
4. Make a preliminary survey of the upwelling regions of the NW African continental shelf to compare the vertical distribution of plankton in upwelling and nonupwelling areas.
