Niskin bottle sample inventory from Alvin dives and shipboard CTD's on R/V Atlantis AT37-13 in the Pacific margin of Costa Rica from May to June 2017 (Costa Rica Seeps project)

Abstract:

This dataset is an inventory of Niskin bottle samples collected by HOV/Alvin and the shipboard CTD on the RV/Atlantis cruise AT/37-13 during May and June 2017 at the Costa Rica Margin (sites Mound 12, Quepos landslide, Jaco Scar).

Methods & Sampling

Niskin water from the CTD rosette or Alvin mounted bottles were filtered upon recovery onto 0.2 µm sterivex filters using a peristaltic pump. Water was stored at 4ºC prior to filtration. Sterivex filters were stored at -80ºC.

Data Processing Description

BCO-DMO Processing Notes:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions
- blank values were replaced with no data value 'nd'

Instruments

CTD - profiler

Supplied Name: SeaBird 911+ CTD with SBE3T/SBE4C sensor system

Supplied Description:

Instrument Type

Generic Name: CTD - profiler

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/130/

Generic Description:

The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. The instrument is lowered via cable through the water column. It permits scientists to observe the physical properties in real-time via a conducting cable, which is typically connected to a CTD to a deck unit and computer on a ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast.

This term applies to profiling CTDs. For fixed CTDs, see https://www.bco-dmo.org/instrument/869934.

Niskin bottle

Supplied Name:

Supplied Description:

24 each10-liter Niskin bottles

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.

Sea-Bird SBE 43 Dissolved Oxygen Sensor

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: Sea-Bird SBE 43 Dissolved Oxygen Sensor

Acronym: SBE-43 DO

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0036/

Generic Description:

The Sea-Bird SBE 43 dissolved oxygen sensor is a redesign of the Clark polarographic membrane type of dissolved oxygen sensors. more information from Sea-Bird Electronics
