Oceanographic profile ALKALINITY, AMMONIA, CHLOROPHYLL A, other measurements collected using bottle and XBT in the North Sea from 1992 to 1995 (NCEI Accession 0000707)

Land-Ocean Interaction Study (LOIS) investigated sediments, nutrients and contaminants from the watershed to the edge of the coastal shelf. The programme quantified and modelled fluxes of these materials and investigated how they are transformed as they move through river catchments, estuaries and coastal seas.

This highly interdisciplinary study considered riverine, atmospheric, estuarine, coastal and shelf processes. The work included a major geological study of the sedimentary record across the coastal zone to determine how fluxes of material have influenced sea level, climate and land use.
