| Abstract |
Seaward of the Inner Bristol Channel, inputs are much less significant in controlling the concentrations of solutes which, in many cases, are distributed in a manner which indicates conservative or near-conservative behavior during mixing between Celtic Sea water and water characteristic of the Outer Severn Estuary. Biogeochemical processing of elements, which is insignificant within the Severn Estuary, becomes increaseingly significant seawards, and is evidenced by seasonal changes in nutrient concentrations and in suspended particulate composition. These chemical variations are primarily attributable to primary production within the Bristol Channel which thrives on the rich nutrient supply emanating from the highly turbid, and correspondingly unproductive, Severn Estuary. |
