Interrelations between secular sea level variations and subsidence of coastal areas in the North sea
Summary The effect of secular sea level variations on coastal levelling nets was considered for some parts of the North West European Lowlands levelling. On neglecting local geological influences a simplified global model was used for treating the following problems: (1) Magnitude of secular tilt effects in NWELL due to possible sea level variations; (2) Levelling errors due to sea tide loadings. 相似文献

The Northern Adriatic is one of the most productive regions of the Mediterranean, primarily due to the eutrophicating influence of Italian rivers, in particular the Po. In June 1977 unusually high phytoplankton standing crops (13 μg Chl a l.?1) occurred, together with extremely low dissolved oxygen concentrations in bottom waters (to 13%) which persisted for 4–6 months. Such conditions were associated with unusual climatic conditions creating increased discharge from the Po.The data indicate long term meteorological changes which may alter the biological characteristics of the region to a degree equal to, or exceeding, those created by anthropomorphic eutrophication.The 1977 data are presented, discussed, and contrasted with a 10 year data series. 相似文献

The United Nations established an Environment Programme which was reported in an earlier issue of the Marine Pollution Bulletin. Its Director, Maurice Strong addressed the UN Law of the Sea Conference at Caracas on the need for conservation measures to go hand in hand with exploitation of marine resources, and he indicated the role of UNEP in this. His speech was not reported at the time. It is vital that it should not be forgotten when the Law of the Sea Conference resumes next year in Geneva. The main points of his speech are given here. 相似文献
