Cruise plan

Cruise Info.
Ship name (ship code)	Unknown self-propelled small boat (ZZ99)
Cruise identifier	RATS/NUT26
Cruise period	1997-08-13 — 1997-08-13
Status	Completed
Port of departure	Rothera, Antarctica
Port of return	Rothera, Antarctica
Purpose	Research
Objectives	The RaTS programme (Rothera Oceanographic and Biological Time Series) involves the long term monitoring of a nearshore marine environment and is focussed around two broad aims, 1) Provide a suite of oceanographic data that would provide environmental background to aid interpretation of the nearshore marine ecology and 2) Test a series of broad hypotheses concerning the pelagic-benthic coupling and environmental forcing of the nearshore environment. On an approximate weekly basis, an upper water column CTD cast is deployed with a discrete water sample taken at 15m. The water sample is analysed for macronutrients, chlorophyll, dissolved organic carbon, oxygen isotopes and microbial community.
