Description

Methods & Sampling

Dataset acquisition description

Sampling was performed by HOV Alvin in the Gulf of Mexico and Florida Escarpment area using the following methods:
- Grab - using the claw of either port or starboard manipulator to pick up the sample
- Push core - used to collect sediment core samples, or invertebrates residing in the sediment
- Slurp - use of a vacuum system to collect sample from the seafloor or water column

Data Processing Description

Dataset Processing Description

BCO-DMO Processing:

- added conventional header with dataset name, PI name, version date, reference information
- renamed parameters to BCO-DMO standard
- replaced blank cells with nd or 0 (flags)
- replaced commas with ; and removed / in sampling_method
- replaced blanks with underscores; removed trailing blanks
- replaced '?' with 'maybe'
- replaced '<' with lt_; replaced '>' with 'gt_'
- sorted by taxon, genus, species, dive_id, sample_id
