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 2002-10-31 to 2002-11-11 (NCEI Accession 0112205)

This dataset includes biological, chemical, discrete sample, physical and profile data collected from KEIFU MARU in the North Pacific Ocean and Philippine Sea from 2002-10-31 to 2002-11-11 and retrieved during cruise PACIFICA_49FA20021031. 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 Naoyuki Ishikawa 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_49FA20021031 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2002年10月31日至2002年11月11日期间，于北太平洋与菲律宾海的“启福丸”（KEIFU MARU）科考船上采集的生物、化学、离散样品、物理及剖面数据，相关数据随PACIFICA_49FA20021031航次回收。
数据集包含以下参数：碱度（ALKALINITY）、铵盐（AMMONIUM）、一氟三氯甲烷（CFC-11，CHLOROFLUOROCARBON-11）、二氟二氯甲烷（CFC-12，CHLOROFLUOROCARBON-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（HYDROSTATIC PRESSURE）、硝酸盐（NITRATE）、硝酸盐+亚硝酸盐浓度（NITRATE + NITRITE CONTENT (CONCENTRATION)）、亚硝酸盐（NITRITE）、褐藻素（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）及采水器（bottle）。本数据集由日本气象厅（Japan Meteorological Agency）的石川直幸（Naoyuki Ishikawa）、污染物化学分析中心海洋部全球环境与海洋部门，以及气象研究所的石井正男（Masao Ishii）作为PACIFICA_49FA20021031数据集的一部分完成采集。

PACIFICA（太平洋内部碳项目，PACIFic ocean Interior CArbon）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，由北太平洋海洋科学组织（PICES）碳与气候专题组（S-CC）提供支持。
