Abstract

Data collection and thus also possibilities to have direct information on the marine environment situation in the Latvian Baltic Proper which is covering the Eastern Gotland Basin was stopped in 1994. The real alterations of ecosystem were not estimated, as only indirect data were available. Thanks to the start of National research program KALME, three the most representative sampling locations were visited again in 2007, actually repeating the sampling program of 1994, including basic hydrological observations, nutrient concentrations, abundance and species composition of phyto- and zooplankton and macrozoobenthos. The obtained information on vertical profiles of physico-chemical parameters and the structure of biological variables allows to have a scenery what has happened during 14-15 years - in a period when the environment of the Baltic Sea has been changing under the large-scale climatic pressure and its local variations. This study is discussing the observed changes in the plankton and benthic communities of the Baltic Proper both in the light of numerical values and biological diversity. Taking into account the development of knowledge on the processes in the Baltic Sea and also the current needs for elaboration of the ecosystem-based management we have tried to estimate the adequacy of sampling approach and quality of the obtained data.

回到波罗的海:问题多于答案?
1994年停止了数据收集,从而也停止了获得关于包括东哥特兰盆地在内的拉脱维亚波罗的海地区海洋环境情况的直接资料的可能性。由于只有间接数据,没有对生态系统的真实变化进行估计。由于国家研究计划KALME的启动,2007年再次访问了三个最具代表性的采样地点,实际上重复了1994年的采样计划,包括基本的水文观测、营养浓度、植物和浮游动物以及大型底栖动物的丰度和物种组成。所获得的关于物理化学参数和生物变量结构的垂直剖面的信息使我们能够看到14-15年间发生的情况,在这一时期,波罗的海的环境在大范围的气候压力及其局部变化下一直在变化。本研究从数值和生物多样性两方面讨论了波罗的海地区浮游生物和底栖生物群落的观测变化。考虑到关于波罗的海进程的知识的发展,以及目前对制定基于生态系统的管理的需要,我们试图估计抽样方法的适当性和所获得数据的质量。
