Oceanographic Measurements in river 'Gota Alv', the entrance to Gothenburg (2001)

In January 2001 the Swedish Meteorological and Hydrological Institute realized that the high water flow in the river Gota Alv, the entrance to Gothenburg, during autumn year 2000 and expected high flow in spring year 2001 may exert an influence on the sea, i.e. the Kattegat and the Skagerrak. SMHI, The Swedish Environmental Protection Agency (Naturvardsverket) and the Water Quality Association of the Bohus Coast (Bohuskustens Vattenvardsforbund) co-funded an investigation of possible effects in the area relatively close to the river mouth. The investigation started in February and ended in the beginning of June. The analysis comprises nutrients, chlorophyll a, quantitative phytoplankton, solar radiation and primary productivity. Data on nutrient concentrations in rivers was made available from the Swedish University of Agricultural Sciences (Sveriges lantbruksuniversitet).

2001年1月，瑞典气象与水文研究所意识到，2000年秋季河流哥塔阿尔夫（Gota Alv）的高水位以及预计2001年春季的高水位可能对海洋产生影响，即对卡特加特海峡和斯卡格拉克海峡。瑞典气象与水文研究所（SMHI）、瑞典环境保护局（Naturvardsverket）及博胡斯海岸水质协会（Bohuskustens Vattenvardsforbund）共同资助了对河流入海口附近区域可能影响的调查。该调查于2月开始，并于6月初结束。分析内容涵盖营养素、叶绿素a、定量浮游植物、太阳辐射及初级生产力。河流中营养素浓度数据由瑞典农业大学（Sveriges lantbruksuniversitet）提供。
