Cruise summary report

Cruise Info. 
Ship name (ship code)RRS Discovery (74E3)
Cruise identifierD158
Cruise period1986-04-12 — 1986-05-12
StatusCompleted
Port of departureFalmouth, United Kingdom
Port of returnFalmouth, United Kingdom
PurposeResearch
Objectives1. To monitor the development of the spring bloom and to study the processes of aggregation resulting in the fast-sinking phytodetritus.
2. To collect the sinking material during its passage through the water column and to study the changes taking place during this passage and to quantify the flux.
3. To investigate the significance of the material to the mid-water and benthic communities.
