Distinctive yellow marked tarsi.
Superficially, with the swollen frons it seems likely to be Thoracochaeta?
Also the habitat was shoreline, and on BugGuide I see this is another with the common name of "seaweed fly"...

Two options here in Iceland if so :
Thoracochaeta brachystoma
Thoracochaeta zosterae


On BugGuide it says
"T.brachystoma has only two pairs of bristles on the dorsal surface of the mid tibia and no erect bristles on the hind tibia"
Photo probably not good enough to be certain, but looks likely this is T.brachystoma?
