Currently, over ten years of CTD data are presented. In a few months, moored current meter data will also be made available.

More about RaTS
The RaTS programme is funded by NERC. It involves the long-term monitoring of a nearshore marine environment in the Antarctic. Its aims are to
- aid interpretation of the local ecology
- test a series of hypotheses concerning interactions between surface and deep waters and the environmental forcing of the nearshore environment
Sampling began in January 1997, at a site (Site 1) approximately 4 km from the coast of the BAS station at Rothera. Weather and ice permitting, an upper open hydrographic cast and discrete water sample (at a depth of 15 m) are collected every fifth day during summer and every seventh day during winter.
If Site 1 is inaccessible then the secondary station, Site 2, is occupied; if neither are accessible then a water sample is collected near the wharf at Rothera (Site 3) but no hydrography cast is taken.
