Description

Sample logs from HOV Alvin dives (AL4704-AL4716) on R/V Atlantis (AT26-14) between April - May 2014 in the Gulf of Mexico.

Methods & Sampling

Sample logs were acquired for each dive. UTM coordinates, lat/lons, depths, and sampling descriptions are included.

Data Processing Description

Data Management Office Processing Notes:
-Combined separate deployment files into one table.
-Re-formatted column names to comply with BCO-DMO naming standards.

Instruments

Alvin Slurp Sampler

Supplied Name: Pump

Supplied Description:

Pump used to collect samples from seafloor or water column

Instrument Type

Generic Name: Alvin Slurp Sampler

Generic Description:

Small and large capacity vacuum pump samplers. May have single or multiple chambers. See http://www.whoi.edu/main/alvin/subsystems/optional-scientific-samplers

Niskin bottle

Supplied Name: Niskin

Supplied Description:

Used to collect water samples

Instrument Type

Generic Name: Niskin bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0412/

Generic Description:

A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.

Parameters

Date and time formats are described in python strftime() syntax.
