Ore estuary (Orefjarden), Umea Marine Sciences Centre (LTER)
rivers and lakes
Umeå Marine Sciences Centre produces long term marine time series in the coastal and off-shore environments of the Gulf of Bothnia. The Ore estuary is proposed as the primary study area for the LTER initiative. This is a particularly intensively studied brackish water body with records back to the 1980´s. The estuary is 71.2 km^2 with an average depth of 10 m and maximum depth of 32 m. Salinity is between 1-3 g/kg. The Ore river discharge into the estuary and long term ecological time series i available also from the river. The watershed is dominated by boreal forest and mires.
General Characteristics, Purpose, History
The main purpose of the time series is to assess the ecological and chemical status of the water body. This is funded by the Swedish Environmental Protections Agency and motivated by international agreements. In addition the time series are used to better understand controlling factors of pelagic and benthic productivity, as well as food web structure over large temporal and spatial scales.
