pH, alkalinity, temperature, salinity and other variables collected from discrete sample and profile observations using Alkalinity titrator, CTD and other instruments from the HESPERIDES in the South Atlantic Ocean from 2010-02-08 to 2010-03-10 (NODC Accession 0110255)

NODC Accession 0110255 includes chemical, discrete sample, physical and profile data collected from HESPERIDES in the South Atlantic Ocean from 2010-02-08 to 2010-03-10 and retrieved during cruise CLIVAR_A21_20HE20100208. These data include ALKALINITY, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, NITRITE, PHOSPHATE, SALINITY, SILICATE, WATER TEMPERATURE and pH. The instruments used to collect these data include Alkalinity titrator, CTD, Spectrophotometer for pH measrement and bottle. These data were collected by Fiz Perez and Aida F. Rios of Instituto de Investigaciones Marinas; Departamento de Oceanograffa as part of the CLIVAR_A21_20HE20100208 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.

NODC收录号0110255包含2010年2月8日至2010年3月10日期间，于南大西洋HESPERIDES海域通过航次CLIVAR_A21_20HE20100208获取的化学、离散采样、物理及剖面数据。本次采集的数据涵盖碱度、溶解氧、静水压、硝酸盐、亚硝酸盐、磷酸盐、盐度、硅酸盐、水温及pH值。用于采集这些数据的仪器包括碱度滴定仪、温盐深仪（CTD）、pH测量分光光度计以及采水器。该数据集由西班牙海洋研究所（Instituto de Investigaciones Marinas）海洋学系的Fiz Perez与Aida F. Rios完成采集，作为航次CLIVAR_A21_20HE20100208数据集的一部分。
国际气候变率与可预报性研究（CLIVAR）全球海洋碳与重复水文计划，会对选定的世界海洋环流实验（WOCE）/全球海洋通量联合研究（JGOFS）水文断面开展系统性、全球性的重测作业，以量化热、淡水、二氧化碳（CO₂）及相关参数的储存与输送变化。
