This dataset includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, pH on sea water scale, temperature, salinity, dissolved oxygen, nutrients, chlorofluorocarbons (CFC-11, CFC-12, CFC113), carbon tetrachloride (CCL4), tritium, and helium obtained during the R/V Charles Darwin cruise CD139, CLIVAR_I05_2002 (EXPOCODE 74AB20020301) in the Indian Ocean from 2002-03-01 to 2002-04-15. These data were collected by M. Alvarez of Commonwealth Scientific and Industrial Research Organization, Aida F. Ríos of Instituto de Investigaciones Marinas; Departamento de Oceanograffa and H. Bryden [affiliation unknown] as part of the CLIVAR_I05_2002 data set. The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.
This dataset is available to the public for a wide variety of uses including scientific research and analysis.

spectrophotometer, optical spectrometer, spectrograph or spectroscope
An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials.
Butler, L. R. P.; Laqua, K. (1995). "Nomenclature, symbols, units and their usage in spectrochemical analysis-IX. Instrumentation for the spectral dispersion and isolation of optical radiation (IUPAC Recommendations 1995)". Pure Appl. Chem. IUPAC. 67 (10): 1725–1744. doi:10.1351/pac199567101725. A spectrometer is the general term for describing a combination of spectral apparatus with one or more detectors to measure the intensity of one or more spectral bands."

Updated information from ICES for the vessel CHARLES DARWIN from UNITED KINGDOM
Code : 74AB
Name : CHARLES DARWIN
Flag : UNITED KINGDOM - GB (ISO Country Code)
Call Sign : GDLS
Title : RRS
Platform Class : Research vessel
IMO : 8207941
Commissioned Date : 1985-02-13
Decommissioned Date : 2006-06-30
Current Length : 69.4
Built : 1984
Notes : NERC deep-sea research vessel until sold in July 2006 and renamed Ocean Researcher.
Same Vessels Info
74OA - OCEAN RESEARCHER
General Comments:
Wikipedia claims a build date of 1985, which is incorrect. I saw her in Falmouth fully fitted out and undergoing acceptance trials in September 1984. 1985-02-13 is date of first cruise.
In Jan. 2007, the name associated with the code 74AB was changed to OCEAN RESEARCHER. In Feb. 2007 an additional code was created for the OCEAN RESEARCHER. In 2009, the platform group agreed attribute change and code creation procedures. The name for 74AB was changed back to CHARLES DARWIN.
