Project: DeepCCZ

Acronym/Short Name:DeepCCZ

Project Duration:2016-11 - 2020-08

Geolocation:Western Clarion-Clipperton Zone of the North Pacific Subtropical Gyre (~5N 142 W to ~11N 154 W)

GBMF Grant Name: Closing Gaps in Knowledge About Biodiversity and Ecology of the Deep Sea to Better Assess the Impacts of Deep-Sea Mining

GBMF Grant Statement: To generate a better understanding of the biodiversity oand ecology of a large deep-sea ecosystem prior to mining

Expected Measurements:

Shipboard underway data: meteorological data, navigation data, and processed multibeam mapping data,
processed CTD water-column environmental data (e.g., water temperature, pH, salinity, light),
raw ROV video records and associated environmental sensor data
raw free vehicle baited video and still imagery
specimen capture records (ROV and trap - location, date, time, and all body measurements)
processed DNA sequence data for captured animal specimens
processed metagenomic DNA sequence data for microbial assemblages in sediment and water samples
sediment community respiration and nutrient regeneration data
isotopic data for sediment infaunal organisms

Anticipated Derived Data Products:

Biodiversity, abundance, and species composition of benthic megafauna, mobile scavengers, and sediment microbes at each study location
Sediment community function (respiration, nutrient regeneration, detrital processing) at each study location
Genetic connectivity at species and population levels for key megafaunal and mobile scavenger species between study locations.
