CTD profile data from 30-ODF/SIOR (Ocean Data Facility 12 bottle, 30 liter Niskin rosette) 1m Downcasts
CTD/Hydrographic Measurements Program Two types of rosette/SBE9plus CTD casts (65 SIOR/30L-Niskin and 40 GT-C/15L-GoFlo) were made at 22 station locations during GEOTRACES 2011. 13 shallow and 13 deep McLane pump profiles were done at all Full and Super Stations, with an SBE19plus CTD attached to the end of the wire.
Refer to KN204-01 A/B Cruise Report for detailed descriptions of acquisition and processing methodologies
Processing Notes: 14 Feb 2013: BCO-DMO corrected the event number of CTD cast 6 at station 18. The correct event number was verified in the original cast sheets.

Altimeter - Tritech LPRA-200 or Simrad 807
SIOR/30L-Niskin Rosette/CTD casts were performed with a package consisting of a 12-bottle rosette frame (SIO/STS), a 24-place carousel (SBE32) and 12 30L General Oceanics bottles with an absolute volume of 30L each. Underwater electronic components consisted of a Sea-Bird Electronics SBE9plus CTD with dual pumps (SBE5), dual temperature (SBE3plus), reference temperature (SBE35RT) dual conductivity (SBE4C), dissolved oxygen (SBE43), transmissometer (WET Labs C-Star), fluorometer (Seapoint SCF) and altimeter (Tritech LPRA-200 or Simrad 807). A second dissolved oxygen plus oxygen temperature sensor (JFE Advantech RINKO-III) was incorporated into the data stream for future sensor evaluation; it was not processed for this cruise.
An instrument that measures height above a fixed surface. The data can be used to map ocean-surface topography and generate gridded surface height fields.

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
Fluorometer - Seapoint SCF
A fluorometer or fluorimeter is a device used to measure parameters of fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light. The instrument is designed to measure the amount of stimulated electromagnetic radiation produced by pulses of electromagnetic radiation emitted into a water sample or in situ.
Dissolved Oxygen Sensor - A second dissolved oxygen plus oxygen temperature sensor (JFE Advantech RINKO-III)
An electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed
SBE 43 Dissolved Oxygen Sensor
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
Transmissometer - WET Labs C-Star
A transmissometer measures the beam attenuation coefficient of the lightsource over the instrument's path-length. This instrument designation is used when specific manufacturer, make and model are not known.
