Notes on Vent Field Description:
numerous chimneys emitting buoyant white smoker fluids, as well as irregular shaped mounds with flange structures; approx. 5 km from Troll Wall; southernmost Mohns Ridge, 60 km west of Jan Mayen Island; Schander et al. (2010): "located at a rifted volcanic ridge at 700-750 m depth, where venting takes place at two fields, each 100-200 m across. At both fields white smoker fluids with temperatures up to 260-270 C discharge from numerous chimneys"
Notes Relevant to Biology:
white bacterial mats, shrimp, anemones, crinoids; see Schander et al. (2010): "the Jan Mayen fields do not support a high biomass of vent-endemic fauna"
Year and How Discovered (if active, visual confirmation is listed first):
2005 ROV BIODEEP-05 cruise
