This dataset is U.S. State Department MSR U2011-006 as part of the World Data Service for Oceanography. These data include total alkalinity, (TA), pH on the total scale, water temperature, salinity, dissolved oxygen and nutrients. The instruments used to collect these data include Alkalinity titrator, CTD, Niskin bottles and spectrophotometer. These data were collected by Aída F. Ríos and Fiz F. Pérez of Institute of Marine Research Vigo (IIM) and Alonso Hernández-Guerra of Universidad de Las Palmas de Gran Canaria (ULPGC) as part of the CLIVAR_A05_29AH20110128 dataset. 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.
