Feasibility of seawater heat extraction from sub-Arctic coastal water; a case study of Onundarfjordur, northwest Iceland
We studied the feasibility of seawater heat extraction in Onundarfjordur (Icelandic: Önundarfjörður), a fjord located in the north-western part of Iceland, with sub-Arctic Ocean temperatures. The in-situ seawater temperature in the fjord was measured at different depths and locations from April 2015...
