Notes on Vent Field Description: 
note: Zhou R2K 2008 abstract says CDE is 4 miles S of ABE - however, this location is 10km north of ABE and is same as Tahi Moana 1 site of Nautilus Minerals; chimney structures range from <1m to ~5m tall; evidence of additional hydrothermal plumes to the north and south of CDE; 4 miles north of R2K ISS Bulls Eye at ABE; northern segment of Eastern Lau Spreading Center (ELSC)
Notes Relevant to Biology: 
microbial mats, anemones, crabs, fish
Year and How Discovered (if active, visual confirmation is listed first): 
2007 towed video camera; 2004 plume only; 2008 commercial ROV
