River Atmosphere Coastal Study

Project Description
The River-Atmosphere-Coast Study (RACS) of the Natural Environment Research Council (NERC) of the United Kingdom studies land-sea interactions in the coastal zone and the major exchanges (physical, chemical & biological) between rivers and estuaries and the atmosphere.

The east coast of Britain between Berwick-on-Tweed and Great Yarmouth is the ... chosen site for RACS. The coastal marine study consists of several seasonal research cruises (using the NERC vessel 'RRS Challenger') along the east coast of the UK, probing the North Sea, its major estuaries (the Wash, the Humber, the Tyne and the Tees) and the English Channel. The data include RRS Challenger cruises 99 (December 1992), 108 (November/December 1993) and 115 (October/November 1994). The objectives of the cruises were to define the characteristics of the plume emanating from the Humber/Wash estuaries into the coastal zone, and to carry out surveys of the LOIS coastal study area, with particular attention given to sediment and suspended particulate matter (SPM) characteristics and water quality.

In addition, an intensive study of fluxes in the Humber Estuary is taking place aboard the NRA's vessel 'Sea Vigil', monitoring processes as far inland as the Aire-Ouse confluence.
