The depth capabilities of offshore oil technologies have increased substantially over the last four decades. Recently exploratory drilling operations have been conducted in water as deep as 2119 m and oil and gas production facilities have been installed in 311 m of water. The maximum potential impact of the technology is computed yearly using annual depth records which are converted into area of seafloor. In one region, the Western Gulf of Mexico, deep water production capability had exceeded the bathymetric limits and hence area of the geologic shelf by 1975. On a global scale if depth is the sole constraining factor, up to 53 million km2 or 15% of ocean-area is now open to exploratory drilling. This is equivalent to 37% of all land area above sealevel. Using the same bathymetric constraint up to 23 million km2 worldide became available for production by 1978. These subsea areas will influence global supply during times of high demand for oil and gas.

This paper reviews the dredging of aggregates in the North Atlantic, North Sea and Baltic Sea area in the period 1979–1985. It is estimated that the following average amounts are extracted per year: sand for building purposes 40 million m3; gravel 9 million m3; calcareous material 1 million m3; maintenance dredging (sand) 400 million m3. Sand for building purposes is mainly extracted in the southern North Sea, gravel along the English east coast and Channel, shell in the Wadden Sea (North Sea) area of the Netherlands, West Germany and Denmark. Intensive maintenance dredging is carried out along the American east coast and in the southern North Sea (estuaries of the rivers Rhine, Scheldt and Meuse). At present, the short term environmental impact of aggregate extraction activities is small. However, the dumping of polluted harbour dredgings from the ports of Rotterdam and New York is already causing problems. Conflicts might arise with fisheries interest from gravel extraction in the North Sea, where in heavily dredged areas there may be a permanent shift in the species composition of the benthic fauna
