Nice dive,

Sandy bottom with many Asterias rubens (Vanlig sjöstjärna) common seastar, some Halichondria cf. panicea, and name kinds of crabs: UNID hermit crab (many individuals of many sizes); one big ass Cancer pagurus;

The water on the top 2 m was 5° C brown and murky but deeper than that water was warm 7-8 °C and very clear blue. The top layer water must be runoff from rivers that with the wind west wend up inside of the "Fjord".

Air temperature = -1 °C
