| 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. | ||||||||
