Field Activity 2020-641-FA

Identifier 2020-641-FA
Also known as NA124
Purpose This cruise will generate baseline information for locations in the Southern California Borderland (SCB), describing community structure across poorly explored, mineral-rich ecosystems associated with phosphorites and ferromanganese crusts.
Location Southern California Borderland, California, United States, Pacific Ocean
Summary A total of 57 rocks were collected by ROV grab during 8 ROV dives with the following preliminary visual IDs: 14 phosphorite rocks, 7 ferromanganese crusts, 25 basalts, 10 sedimentary rocks, and 1 quartz rock.
Info derived ground truth of mineral distribution, and the mineralogy and chemistry of mineral samples we collect.
Comments This is a cruise funded by NOAA OER; the Chief Scientists are Dr. Lisa Levin, UCSD, Scripps and Dr. Paul Jensen, UCSD, Scripps; USGS participation is as a supporting/guest scientist.
