Description

Hydrographic data collected by CTD during RVIB Nathaniel B. Palmer cruise in the Ross Sea, Southern Ocean from 2017-2018.

Methods & Sampling

Dataset acquisition description

Hydrography data were collected using a Sea-Brid SBE 9 CTD with an SBE 11plus deck unit. The CTD was equipped with sensors to measure temperature, conductivity, pressure, dissolved oxygen, fluorescence, altimetry, beam transmission and irradiance.

Locations: Amundsen Sea, Ross Sea, Terra Nova Bay

Data Processing Description

Dataset Processing Description

Data collected from the CTD were processed using Seasave version 7.26.1.8. The data included are from the downcasts.

BCO-DMO Data Manager Processing Notes:
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions (spaces, +, and - changed to underscores). Units in parentheses removed and added to Parameter Description metadata section.
* Concatenated 79 .csv files into one tabular dataset.
* Added column "Station" with the station number from the originally submitted csv filename.
* Changed date format from m/d/Y to ISO 8601 formatted date Y-m-d
* Extracted time from "Julian Day" and "Date" to construct ISO_DateTime_UTC.
* Data sorted by ISO_DateTime_UTC,Station,Pressure,Depth

CTD Sea-Bird SBE 911plus

Supplied Name:

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
