Marine systems vary in their sensitivities to perturbation. Perturbation may be insidious - such as increasing eutrophication of coastal areas - or it may be dramatic - such as a response to an oil spill or some other accident. Climate change may occ

Biogeochemical processes and fluxes occurring across the sediment–water interface on continental margins impacted by oxygen minimum zones (OMZs) are important to bioelement cycles, ocean inventories, and productivity. The nature and magnitude of th

Benthic biogeochemical processes in the oceans’ oxygen minimum zones (OMZs) are of global significance, yet they remain poorly defined. Here, sedimentary manganese, iron, and sulphur cycling are studied at sites above, within and below the OMZ on t

The exploration and production of North Sea oil and gas reserves has resulted in the accumulation of large quantities of drill cuttings on the seabed surrounding drill sites. This complex mixture of man-made and natural substances contains higher con

A multidisciplinary cruise to the northern North Sea was undertaken during June 1999 to carry out a Lagrangian study of an Emiliania huxleyi bloom. During this experiment, the naturally occurring radionuclide, 234 Th, was measured in the water column

In taking this overview, it is clearly necessary to identify some major contributions that have helped us understand the complexity of the marine environment that embodies the Atlantic Margin to the west of Scotland. Here, I attempt to provide a poin

A biogeochemical study of recent (multicores) sediments of the northwest African slope was undertaken to understand how the sediment composition varies with respect to the location of core sites relative to the centers of coastal upwelling, and how t

A common feature in δ15N profiles downcore in continental margin sediments is that the heaviest δ15N values are frequently observed during the deglaciation (i.e., between 12,000 calendar years BP and the climatic optimum at 6000 yrs BP), not at the

We have studied the sediment geochemistry and benthic foraminiferal fauna in a piston core from the northwest Arabian Sea (covering the last 150,000 years), and compared the results with the stable isotopic record from both benthic (Uvigerina peregri
