Description: LOIS was a 6 year project (1992 - 1998) of the UK's Natural Environment Research Council involving over 360 scientists from 11 institutes and 27 universities. This project was the United Kingdom's contribution to LOICZ. It aims were to quantify and simulate the fluxes and transformations of materials (sediments, nutrients, contaminants) into and out of the coastal zone, extending from the catchment to the edge of the continental shelf. The main study area, embracing river catchments, estuaries and coastal seas, was the UK East Coast from Berwick upon Tweed to Great Yarmouth, concentrating on the Humber and its catchment, and to a lesser extent the River Tweed. The shelf edge study was focused on an area to the west of Scotland.
