Vent Sites:
Drachenschlund (= Dragon Throat)
Notes on Vent Field Description:
crater resembled Logatchev; extinct smokers nearby; plume Nibelungen detected in 2004 on cruise M62/5; Drachenschlund (black smoker) found in 2006 on cruise M68/1
Notes Relevant to Biology:
striking absence of fauna around the crater
