Name Alias(es):
COMRA Discovery Expedition
CDE
CELSC Plume 12
plume 21, C-ELSC
Tahi Moana
Notes on Vent Field Description:
this location is ~10 km (~4 miles) north of ABE (R2K ISS Bulls Eye) on northern segment of Eastern Lau Spreading Center (ELSC); chimney structures range from <1m to ~5m tall; note: Zhou and Yang 2008 "A hydrothermal field named as "CDE"(COMRA Discovery Expedition) at 176°11'W, 20°40'S, about 4 miles south of known ABE hydrothermal field, was discovered by R/V DaYang YiHao in May, 2007"; however, that position is actually ~4 miles north of ABE;
Notes Relevant to Biology:
microbial mats, anemones, crabs, fish
Year and How Discovered (if active, visual confirmation is listed first):
2008 commercial ROV; 2004 plume only
