Chlorophyll-a Content in the Kattegat (1989-2001)

The project objectives are: - to follow the dynamics of chlorophyll - to detect phytoplankton blooms - to give early warning when phytoplankton blooms occur - to monitor long-term fluctuations in chlorophyll amounts - to evaluate fluctuations in chlorophyll amounts Chlorophyll is monitored at the sampling site Anholt E. The sampling station is included in the HELCOM Combine programme. Frequency of sampling is 20-25 times per year, with a lower intensity during the winter months. Samples for quantitative phytoplankton analysis, primary production, water chemistry and physics are obtained simultaneously. Between August 1989 and December 1996, with some interruptions, chlorophyll was monitored at the sampling station Hallands Vadero, located in the outer part of Laholm Bay. Data from simultaneous sampling for water physics/chemistry are stored at the Swedish Meteorological and Hydrological Institute, SMHI.

本项目的目标旨在：追踪叶绿素的变化动态；探测浮游植物的暴发；在浮游植物暴发时提供早期预警；监测叶绿素数量的长期波动；评估叶绿素数量的波动情况。叶绿素在采样点安霍特E进行监测。该采样站被纳入赫尔科姆综合计划之中。采样频率为每年20至25次，冬季月份的采样强度较低。同时获取用于定量浮游植物分析、初级生产、水质及物理特性的样品。自1989年8月至1996年12月，期间虽有间断，叶绿素在位于拉霍尔姆湾外部的采样站霍尔兰德瓦德罗进行了监测。同时进行的水文/化学采样数据存储于瑞典气象水文研究所（SMHI）。
