“…South of the Flamborough-Helgoland front (see hatched area, Fig. 2), the shallower waters tend to remain well mixed and warmer throughout the year apart from occasional and temporary salinity stratification (Simpson et al 1977;Vested et al 1996;Ducrotoy et al 2000). The region of the Oyster Grounds ( Fig.…”

“…The region of the Oyster Grounds ( Fig. 1) exhibits thermal stratification, albeit for a shorter period than the north (Greenwood et al 2010), while the shallow region of the Dogger Bank shows greatly reduced stratification compared to the north (Vested et al 1996;Ducrotoy et al 2000). Sharples et al (2006) showed that the main factor regulating the onset and strength of the stratification was local meteorology, particularly spring air temperatures, and that input of north-east Atlantic water played a reduced role.…”

Spatial extent and historical context of North Sea oxygen depletion in August 2010

et al. 2012

Prompted by recent observations of seasonal low dissolved oxygen from two moorings in the North Sea, a hydrographic survey in August 2010 mapped the spatial extent of summer oxygen depletion. Typical near-bed dissolved oxygen saturations in the stratified regions of the North Sea were 75-80 % while the well-mixed regions of the southern North Sea reached 90 %. Two regions of strong thermal stratification, the area between the Dooley and Central North Sea Currents and the area known as the Oyster Grounds, had oxygen saturations as low as 65 and 70 % (200 and 180 lmol dm -3 ) respectively. Low dissolved oxygen was apparent in regions characterised by low advection, high stratification, elevated organic matter production from the spring bloom and a deep chlorophyll maximum. Historical data over the last century from the International Council for the Exploration of the Sea oceanographic database highlight an increase in seasonal oxygen depletion and a warming over the past 20 years. The 2010 survey is consistent with, and reinforces, the signal of recent depleted oxygen at key locations seen in the (albeit sparse) historical data.

Southern Iberian Peninsula coastal waters have a high ecologic and economic value. e objective of this work has consisted of describing numerical models which simulate the dispersion of particle-reactive tracers in these waters and reproducing measured concentration levels in water and bed sediment samples. Additionally, information on suspended matter concentration distributions and sedimentation rates is obtained. In the Alboran Sea, the model has been applied to simulate the transport of radionuclides introduced from atmospheric fallout. Transport pathways of heavy metals discharged from three rivers draining a large mining area have been obtained for the Gulf of Cadiz. It has been found that these rivers constitute a source of trace elements to the Mediterranean through the Strait of Gibraltar. Some characteristic times have been calculated, as well as �uxes of isotopes through the Strait of Gibraltar, as additional results of environmental interest.

“…This time, there were ecosystems models, e.g. Vested et al (1996), that included hydrodynamics too, and detailed numerical methods on modelling fronts, James (1996), and further work on plumes by de Kok (1996). The real innovation was a paper by Luyten (1996) that gave an extension to the Blumberg-Mellor (Blumberg and Mellor 1987) turbulence closure scheme, raising the level of sophistication of shallow sea modelling.…”
