Description

Methods & Sampling

Dataset acquisition description

Measurements were taken over varying time intervals in order to conserve battery for longer ACM missions. The data are time/date stamped accordingly. ACM's are manufactured by Falmouth Scientific, Inc. and are 2-Dimensional ACMs. The models are identical, and the firmware is the same except for one of the Gulf of Mexico deployment ACMs, which featured newer Firmware.

Data Processing Description

Dataset Processing Description

The data has been minimally processed.

Instruments

Deep-Sea Current Meter and Larval Trap Mooring

Supplied Name: ACM

Supplied Description:

Instrument Type

Generic Name: Deep-Sea Current Meter and Larval Trap Mooring

Acronym: SEEPC mooring

Community Identifier: http://vocab.nerc.ac.uk/collection/L06/current/48/

Generic Description:

The Deep-Sea Current Meter and Larval Trap Mooring is a seafloor anchored mooring equipped to collect sediment/invertebrate larva, and record deep-sea ocean current and acoustical data.

Instruments on the mooring have included sediment traps and a Falmouth Scientific Inc. Acoustic Current Meter with vector-averaged current speed and direction.
