Nutrient concentrations in coastal waters are influenced not only by land runoff, point sources, and water exchange with the sea but are also modified by settlement to and release from sediments. This complicates evaluation of measures to reduce nutr

Highlights • Lab-test showed efficient entrainment of bottom water and moderate oxygenation • In salt-stratified basin ventilation oxidized and removed H2S and nutrients • Induced stratification erosion promoted inflow oxidation in salt-stratif

Internal phosphorus (P) loading from sediments, controlled by hypoxia, is often assumed to hamper the recovery of lakes and coastal areas from eutrophic conditions. We use a box-model to calculate seasonal and annual inputs, export, retention and int

At two stations in a Norwegian land-locked fjord, one more and one less influenced by freshwater run-off, studies were made of the primary production, chlorophyll a concentrations, and the quantity and composition of phytoplankton. Samples were taken

The study covers the period February to August 1978. The hydrography differed little from that of the coastal water in general, possibly with the exception of a more stable surface layer. Salinities at the surface ranged from 27.7‰ to 32.9‰ in th

Phosphate, silicate, nitrite/nitrate, and ammonia were studied in a Norwegian land-locked fjord during 1973. In the surface water the concentrations were similar to what has been found in the North Sea, with the exception of silicate, which occurred
