The Gulf of Bothnia

Ammonium and ammonia concentration parameters in water bodies; Air pressure; Air temperature; Cloud cover height and extent; Dissolved oxygen parameters in the water column; Wind strength and direction; Nitrate concentration parameters in the water column; Phosphate concentration parameters in the water column; Salinity of the water column; Dissolved total and organic nitrogen concentrations in the water column; Nitrite concentration parameters in the water column; Silicate concentration parameters in the water column; Dissolved total or organic phosphorus concentration in the water column; Temperature of the water column

The aim of the investigation is to follow the physical-chemical condition in the Swedish coastal zone of the Bothnian Bay. The investigation will also serve as reference for other investigations performed in contaminated areas. The programme shall also generate data that can be used to support interpretation of other effect studies. Three sampling locations in the Raane archipelago are visited 5 times a year. The data are quality inspected. Checks were made by manual control.
