Description

Methods & Sampling

Dataset acquisition description

Sampling and analytical procedures:

Temperature, salinity, oxygen concentration, and PAR were measured using a Sea-Bird SBE-911+ CTD platform equipped on the rosette deployment system.

Chlorophyll a was measured using a WetLabs FLNTU combination fluorometer and turbidity sensor equipped on the CTD rosette.

For data processing information see https://www.rvdata.us/search/cruise/AE1319 for further details.

Data Processing Description

Dataset Processing Description

BCO-DMO Processing:
- data submitted in Excel file "AE1319_BCODMO.xlsx" sheet "SHEET1" extracted to csv
- added conventional header with dataset name, PI name, version date
- renamed columns to conform with BCO-DMO naming conventions (removed spaces)
- rounded yrday_utc to 2 decimal places

Instruments

CTD Sea-Bird SBE 911plus

Supplied Name: Sea-Bird SBE-911+

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird SBE 911plus

Acronym: CTD SBE 911plus

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/

Generic Description:

The Sea-Bird SBE 911 plus is a type of CTD instrument package for continuous measurement of conductivity, temperature and pressure. The SBE 911 plus includes the SBE 9plus Underwater Unit and the SBE 11plus Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 plus and SBE 11 plus is called a SBE 911 plus. The SBE 9 plus uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 plus and SBE 4). The SBE 9 plus CTD can be configured with up to eight auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). more information from Sea-Bird Electronics
