Field Activity 2015-005-FA

Identifier

2015-005-FA

Purpose

Upper slope gas hydrate dynamics on disparate part of the margin (with and without seeps; with and without long erosional history)

Location

Atlantic margin between Alvin Canyon and Cape Hatteras

Summary

Piston cores, multicores, real-time video on multicores, EK60 data, Chirp 424 data, CTDs

Info derived

heat flow data; water column CH4 concentrations; subbottom imaging; pore water organic & inorganic chemistry, gas composition and carbon isotopes

Comments

> PISTON CORING CRUISE (using PCMSC gear) > Heat flow instrumentation will be provided by NSF facility at UCSC > Edgetech 512 needed > CTD will be provided and staffed by U Delaware
