Field Activity 2022-005-FA

Identifier 2022-005-FA
Alternate names Ocean Infinity Proj Num: 104313
Purpose High resolution mapping and photographic imaging of past nodule extraction activities
Location Blake Plateau
Summary Data were collected using a Hugin 6000 AUV launched from the M/V Deep Helder during 7 dives between Aug 5th and 11th. Data were collected along 758 linear kilometers of survey lines covering approximately 29 square kilometers.
Info derived Seafloor morphology, sub-bottom structure, benthic environmental characterization
Comments This survey was originally planned for the NOAA Ship Nancy Foster, but is now using the M/V Deep Helder owned and operated by MMT/Ocean Infinity https://www.mmt.se/fleet/deep-helder/
