BOTTNISKAVIKENS EKOLOGI: NÄRINGSVÄVSSTRUKTUR, MATERIALFLÖDEN OCH TRENDER / Food Web Structure, Carbon Flow and Trends in the Gulf of Bothnia, Baltic Sea
The reason(s) to the marked ecological differences berween the Bothnian Bay and Bothnian Sea, and the potential coupling to their different biogeochemistry, is unclear. Lack of simultaneous estimates of ecological parameters with sufficient spatiotemporal sampling frequency in the off-shore environment hampers the understanding of the marine food web in the Gulf of Bothnia. To improve this paucity of information a multi-disciplinary joint study between Swedish and Finnish marine scientist was conducted in the Gulf of Bothnial991. A total of 18 cruises were performed during the year of investigation encompassing 25 hydrographical, chemical and biological parameters in both water column and bottom sediments. A set of four intensive stations were visited and sampled over a depth of 100 m or more at the ott-snore stations.
