Dissolved inorganic carbon, pH, alkalinity, temperature, salinity and other variables collected from discrete sample and profile observations using CTD, Coulometer for DIC measurement and other instruments from the KEIFU MARU in the North Pacific Ocean and Philippine Sea from 2003-10-28 to 2003-11-17 (NCEI Accession 0112209)

This dataset includes biological, chemical, discrete sample, physical and profile data collected from KEIFU MARU in the North Pacific Ocean and Philippine Sea from 2003-10-28 to 2003-11-17 and retrieved during cruise PACIFICA_49FA20031028. These data include ALKALINITY, AMMONIUM, CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), Chlorophyll a, DELTA CARBON-13, DISSOLVED INORGANIC CARBON, DISSOLVED ORGANIC CARBON, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, NITRATE + NITRITE CONTENT (CONCENTRATION), NITRITE, PHAEOPHYTIN, PHOSPHATE, Potential temperature (theta), SALINITY, SIGMA-THETA, SILICATE, TOTAL PHOSPHORUS, WATER TEMPERATURE and pH. The instruments used to collect these data include CTD, Coulometer for DIC measurement and bottle. These data were collected by Keizo Shutta of Japan Meteorological Agency; Pollutants Chemical Analysis Center; Marine Division; Global Environment and Marine Department and Masao Ishii of Meteorological Research Institute as part of the PACIFICA_49FA20031028 dataset.

PACIFICA (PACIFic ocean Interior CArbon) was an international collaborative project for the data synthesis of ocean interior carbon and its related parameters in the Pacific Ocean. The North Pacific Marine Science Organization (PICES), Section of Carbon and Climate (S-CC) supported the project.

本数据集涵盖2003年10月28日至2003年11月17日，于北太平洋及菲律宾海的KEIFU MARU（开福丸）上采集，并在航次PACIFICA_49FA20031028期间获取的生物、化学、离散样本、物理及剖面数据。所包含的数据如下：碱度（ALKALINITY）、铵（AMMONIUM）、氯氟烃-11（CHLOROFLUOROCARBON-11, CFC-11）、氯氟烃-12（CHLOROFLUOROCARBON-12, CFC-12）、叶绿素a（Chlorophyll a）、碳-13同位素比值（DELTA CARBON-13）、溶解无机碳（DISSOLVED INORGANIC CARBON）、溶解有机碳（DISSOLVED ORGANIC CARBON）、溶解氧（DISSOLVED OXYGEN）、静水压力（HYDROSTATIC PRESSURE）、硝酸盐（NITRATE）、硝酸盐+亚硝酸盐含量（浓度）（NITRATE + NITRITE CONTENT (CONCENTRATION)）、亚硝酸盐（NITRITE）、脱镁叶绿素（PHAEOPHYTIN）、磷酸盐（PHOSPHATE）、位温（Potential temperature, theta）、盐度（SALINITY）、西格玛θ密度（SIGMA-THETA）、硅酸盐（SILICATE）、总磷（TOTAL PHOSPHORUS）、水温（WATER TEMPERATURE）以及pH值。采集上述数据所用的仪器包括温盐深仪（CTD）、溶解无机碳测量库仑计（Coulometer for DIC measurement）以及采水器（bottle）。本数据集的数据由日本气象厅Keizo Shutta、污染物化学分析中心、海洋部、全球环境与海洋部门，以及气象研究所的Masao Ishii共同采集，作为PACIFICA_49FA20031028数据集的组成部分。
PACIFICA（全称PACIFic ocean Interior CArbon，即太平洋内部碳循环项目）是一项针对太平洋内部碳及其相关参数开展数据合成的国际合作项目。北太平洋海洋科学组织（PICES）下属的碳与气候分会（S-CC）为该项目提供了支持。
