©2020 Biological and Chemical Oceanography Data Management Office.The cruise goals were to collect samples to explore the following objectives:
1) Link geochemical and microbial dynamics along the ELSC
2) Use of metagenomic and transcriptomic data to explore biogeochemical cycles that are regulating the functional roles of the microbial communities in vent fields along the ELSC.
3) Use the metagenomic information to enrich for targeted novel Thermoprotei and acidophiles.
Cruise RR1507 departed from Auckland, 21 April 2015, and arrived on site April, 24. Unfortunately, due to mainly weather related issues, almost 9 of the 15 planned sampling days with the Remotely Operated Vehicle (ROV), Jason, were lost. During the cruise, about 54 different vent deposits and about 27 (duplicate) hydrothermal fluid samples were collected for microbiological and geochemical investigations.
