We have sampled monthly since July 2008 in Adolfbukta in Billefjorden, a threshold fjord located in Isfjorden. Our station is named BAB (Billefjorden AdolfBukta) and is located at 78º 39.72' N and 16º 44.34' E map. The bottom depth at this location is 190 m. Deepest part of Adolfbukta is ca. 200 m and here we have placed a well equipped mooring which measure continuously several parameters (see mooring for more information).
