Dive R502 | |||||||
Dive Plan: Objectives of ASHES Dive: 1) Sample high temperature fluids at Hell, Inferno and Virgin. 2) Sample diffuse flow at 2 diffuse flow sites. 3) Suction sample FeOxide and it's fluid at west wall. | |||||||
4) Suction sample sulfide worms at base of Hell (Porkchop) and Hillock/Phoenix. 5) Sulfide worm behavioral observations at Phoenix. 6) Suction sample clams and other large animals, if encountered. | |||||||
7) Suction sample particulates for edifice tube worm grab site. 8) Suction sample oxides to south of vent field. 9) Recover High temp HOBO at Virgin. 10) Recover SOSUS sound source. | |||||||
Note: Nav fixes not edited in the logs. All fixes were logged, regardless of accuracy. Use the dive plots to determine actual positions. | |||||||
