1979年12月29日笔者代表我国科学家首次正式赴南极考察,从此揭开了中国南极科学考察史上的第一页。当年还不到40岁的“小伙子”,而今不少人已经称我“董老儿”了。虽深知这是对我的尊称,但心里不是个滋味儿,人就这么老了?但我并不后悔,因为我这一生毕竟为我国蒸蒸日上的南极事业作出了贡献!仅仅25年,我国的南极事业从无到有,并已经成为国际南极大家庭中举足轻重的成员,我为之感到自豪!说句心里话,我内心里还真的从未觉得我已经到了“廉颇老矣”的时候,虽然没有“我真的还想活上500年”的雄心壮志,但在有生之年,我会继续把精力用到极地的科学研究上去! 相似文献

Species composition and biomass of plankton samples taken on transects across an upwelling plume off Farewell Spit in February 1981 are presented. Copepods were numerically dominant, particularly Oithona similis and Paracalanus indicus. Also abundant were large phytoplankters (Chaetoceros sp. and Trichodesmium sp.), crustacean faecal pellets, and euphausiid larvae. The distribution of zooplankton species suggests mixing of inshore waters and neritic populations with upwelled waters. These data are discussed with respect to an interpretation of the upwelling system as a northwards transport of zooplankton and its enhanced productivity into the South Taranaki Bight. 相似文献

Of major concern to the UK fishing industry at present is how UK-caught fish may be marketed more effectively. This depends principally upon the objective of the marketing exercise. With respect to export markets, the principal objective is to get the catch sold for a realistic price. Where the export market is the principal outlet for the catch, it is argued that the floor price set by the EEC needs to reflect the world market price. Where the catch is to be sold on the home market, the objective is to increase the consumption of fresh fish, with the UK fisherman attempting to become the preferred supplier. This is the current policy of the Sea Fish Industry Authority (SFIA). 相似文献

A preliminary scuba survey of oligotrophic Lake Rotoma in 1972 revealed a vegetation mainly composed of native hydrophytes in which exotics were at an early stage of colonisation. In 1973 the presence of species was recorded in 5708 quadrats (625 cm2) at 1 m intervals along a total of 50 line transects placed systematically around the lake. Water depth was measured, and quadrat cover and substrate type were subjectively estimated. Species frequency calculations showed that the dominant vegetation pattern was a characean meadow of Chara fibrosa f. acanthopitys (A.Br.) R.D.W., Nitella leptostachys var. leonhardii (R.D.W.) R.D.W., and N. pseudoflabellata var. mucosa (Nordst.) Bailey. The charophytes extended over a depth range of 1–17.5 m on a wide variety of substrates and gradients. Native vascular plants were absent from many transects, and had a depth range only from 0 to 4.5 m, with most occurring above 3.5 m. The Low Mixed Community, found in shallow water less than 1.25 m in depth at the northeast end of the lake, provided this area with a high species diversity. Exotic hydrophytes had established in many areas around the lake. The distribution of Lagarosiphon major (Ridley) Moss and Elodea canadensis Michx. appeared to coincide with boating access and fallen submerged trees over a depth range of 0–6.0 m, although much of the available habitat had not yet been exploited. Emergent species were most abundant within the southwest inlet and also in the lagoons surrounding the lake where sheltered conditions and shallow gradients prevail. 相似文献

It is a common observation that the mean length in a fish population progressively decreases as the biomass is reduced by fishing. However, this has not happened with the population of orange roughy (Hoplostethus atlanticus) on the Chatham Rise, New Zealand, even though the biomass is estimated to have declined by almost 80%. Because orange roughy are slow growing it might be expected that mean age (or its proxy, mean otolith weight) would be a more sensitive indicator of biomass decline than mean length. A simulation study shows that this is not true. With equal sample sizes, all three indicators are equally sensitive; on an equal cost basis, mean length is more sensitive than the others. A log transformation increases the sensitivity of age and otolith weight, but it is not clear whether this increase is sufficient to outweigh the much greater costs of measuring age and otolith weight, compared to length. Under the assumption of constant recruitment, it is more likely than not (P = 0.55–0.8) that a change in mean length would have been detected in the Chatham Rise population, given the estimated biomass decline. 相似文献
