烟台市在1993年提前实现了“海上烟台”的奋斗目标之后,又提出了全面创建海洋经济强市的战略。他们以抓开发、高效、科技、管理为主攻主向,使海洋渔业、海洋旅游、海洋工程等均有了长足的发展。尤其是渔业经济,1995年上半年全市水产品总产量达到30.8万吨,虽然比1994年同期只增长6％,但总产值却增长了34.5％,达到了10.9亿元。 相似文献

The correlation between the azooxantellate scleractinian coral distribution and the abundance of the zooplankton in the Atlantic
Ocean is discussed. The analysis is based on a dataset of 943 specimens (82 species) sampled at 87 stations that were performed
during the scientific cruises of Russian research vessels in the Atlantic. The hypothesis concerning if the coral biodiversity
and population density correlate with the zooplankton abundance was tested. The relationships between these parameters are
contradictory. High coral biodiversity and population density were registered for the areas of low and average zooplankton
abundance in the surface waters. 相似文献

为研究黄河入海径流变化条件下河口附近海域盐度扩散特征,以更好地保护河口海域生物资源多样性,本文以黄河下游利津水文站的长序列实测径流数据资料为基础,利用近海水动力模型FVCOM,分析径流变化对黄河口海域盐度的影响规律。结果表明：黄河口与莱州湾之间存在顺时针的环流系统,在余流作用以及涨落潮方向的影响下,黄河冲淡水长期向莱州湾扩散;丰水期黄河冲淡水几乎影响了整个莱州湾,27盐度锋可以到达莱州湾中部,27等盐线的表层包络面积为2 665.61 km2,占莱州湾的1/4左右,枯水期低盐度水只有向南扩散的趋势,27以下的低盐度水集中分布在黄河口门附近,27等盐线的表层包络面积只有199.65 km2;5月份,随着入海径流量增加,27等盐线扩散的范围、距离、方向都会发生明显变化。在对近海生物资源有迫切保护需求的情景下,适当减少其他用水户供水量以增加入海生态径流量,可以有效改善黄河口海域附近的盐度情况,为生物资源的生长繁殖创造良好条件。 相似文献

Relationship between the path of the Kuroshio in the south of Japan and the path of the Kuroshio Extension in the east 总被引：2，自引：0，他引：2
A relationship between paths of the Kuroshio and Kuroshio Extension (KE) is investigated, using the satellite-derived altimetry
dataset of 1993–2008. When the Kuroshio takes the nearshore nonlarge meander path or typical large meander path and resultantly
goes through the deeper channel (about 2500 m) of the Izu-Ogasawara Ridge, the KE path adopts a relatively stable state with
the two quasi-stationary meanders. On the other hand, when the Kuroshio takes the offshore nonlarge meander path and then
passes over the shallower part of the Ridge (about 1000 m), the KE path tends to be convoluted, i.e., an unstable state. 相似文献

1982年第三次联合国海洋法会议产生了《联合国海洋法公约》,美国积极参与并主导了该《公约》的整个谈判过程,对《公约》大部分条款持支持态度,但最终却没有签署《公约》,其原因主要在于它反对《公约》第十一部分关于深海采矿的规定。1994年《执行(公约)第十一部分的协定》对《公约》中与深海采矿有关的部分进行了实质性修改,满足了美国的利益和要求,但美国国内对《公约》还存在其他一些反对意见。目前美国国内各界支持加入《公约》的呼声日益高涨,美国正在积极考虑加入《公约》。 相似文献

Analysis of the sections traversing the polar hydrological front on the shelf of the North-European basin has enabled us to reveal the areas limited by closed isotaches of the sound velocity existing in the interfrontal zone at depths of 50–150 m. These areas represent the closed waveguide which has the property of an underwater sound channel.Translated by Mikhail M. Trufanov. 相似文献

A study was made on the polyculture of the red algae Gracilaria tenuistipitata Chang et Xia f. Liui Zhang et Xia, f. nov. , the shrimp Penaeus penicillatus Alcock and the mud crab Scylla serrata (Forskal) . The photosynthesis of the algae produces the oxygen on which the shrimp and the crab breathe. The algae are the reproductive place of the organism for the food of the shrimp and the carb, also is the shelter of the shrimp and the crab. The shrimp and the crab regard the algae as the vegetable 相似文献

We analyze the components of the carbon system of the Sevastopol bay waters and the balance of main sediment-forming substances
using the data of field investigations in 1998–2008. The interannual variations of total inorganic carbon and the equilibrium
partial pressure of carbon dioxide in the bay water are noted. An increase in the flux of carbon dioxide into the bay and
in the content of organic carbon in bottom sediments is revealed, and an explanation of this phenomenon is given. The priority
accumulation of organic carbon in the sediments of the bay is established. We assess the interannual variation in the relative
abundances of organic and inorganic carbon as an index of the carbon cycle stability. 相似文献

The analysis of the structure of the cryolithozone, facies, and thicknesses of the Quaternary sediments and the results of the physicochemical mathematical modeling of the modern shelf of the western part of the Laptev Sea support the influence of the Late Pleistocene glaciations on the heat conditions and the distribution of the permafrost in the area. A ～200-m thick glacier formed under aerial conditions from atmospheric precipitation represented the metamorphosed snow cover. According to the modeling, the long-living (from 60?50 to 10?4 ky) glacier reduced the thickness of the permafrost rocks in the reviewed shelf area for 280–360 m. The Holocene marine transgression additionally decreased the thickness from 50–140 m on the inner shelf to 220–350 m on the outer shelf. The modern submarine cryolithozone 450-0 m thick is wide-spread in the studied region from the coast to the shelf boundary (isobaths of 130–140 m), where it pinches out at a distance of ～380 km from the coast at a depth of ～250 m above the sea level. 相似文献
