Squid Forest

Squid Forest (Akkarsgogen in Norwegian literature) is an extinct hydrothermal vent field on the Kolbeinsey Ridge, approximately 900 metres (3,000 ft) deep.[1] As with many active vent sites, Squid Forest is a massive sulfide deposit.[2]

Discovery and description

Squid forest was discovered in 1999 during a research cruise of the R/V Håkon Mosby.[2] It consists of two formerly-venting sites, estimated to have vented at 250–300 °C (482–572 °F) to form pyrrhotite, sphalerite, and barite minerals in the mounds.
