Cruise summary report

Cruise Info. 
Ship name (ship code)RRS Challenger (74CH)
Cruise identifierCH16_2
Cruise period1987-06-23 — 1987-07-03
Port of departureTórshavn, Faroe Islands
Port of returnTroon, United Kingdom
Objectives1. To investigate the distributions of phytoplankton, especially coccolithophorids, and relevant hydrographic properties (temperature, salinity, oxygen, inorganic nutrients, light penetration etc.) in the NE Atlantic Ocean (55-65° N, 01-21° W).
2. To make further measurements of biogenic sulphur compounds in surface oceanic waters and the marine atmosphere.
3. To make a preliminary investigation of the production of particulate organic and inorganic carbon in relation to the CO2 chemistry of surface waters.
4. To collect samples of glacial and post-glacial sediments for studies on sedimentation and geochemical processes.
These were successfully achieved, with only minor losses of operational time due to poor weather and equipment failures.
