Cruise Inventory Information
| Long name | RRS Discovery (74E3) cruise D120 |
|---|---|
| Short name | D120 |
| Objectives and Narrative |
The cruise was designed to make further physical and biological investigations of a larger meander in the frontal system separating east Atlantic from West Atlantic water in the vicinity of 32N, 32W. On Cruise 119 batfish and XBT data had suggested that his meander was in the process of forming a detached eddy and on Cruise 120 it was hoped to obtain further batfish profiles of this area.
The biological investigations were mainly centred on an investigation of the effect of the front on primary production, nutrient distribution and the fine-scale vertical distribution of zooplankton. Subsidiary experiments to be carried out were investigations on the zoogeographic distribution of Calanus helgolandicus in the area SW of the Azores, physiological studies of plankton luminescence and, if time permitted, a survey of the effect of a shallow sea-mount on chlorophyll production. |
