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 2007-10-23 to 2007-12-

NODC Accession 0112333 includes biological, chemical, discrete sample, physical and profile data collected from KEIFU MARU in the North Pacific Ocean and Philippine Sea from 2007-10-23 to 2007-12-08 and retrieved during cruise PACIFICA_49FA20071023. 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 Masao Ishii of Meteorological Research Institute; Geochemical Research Department and Tatsushi Shiga [affiliation unknown] as part of the PACIFICA_49FA20071023 data set.

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.

NODC编号0112333包含2007年10月23日至2007年12月8日期间，在北太平洋与菲律宾海由KEIFU MARU号科考船采集，并在PACIFICA_49FA20071023航次中获取的生物、化学、离散采样、物理及剖面数据。该数据集涵盖的参数包括：碱度、铵离子、氯氟烃-11（CFC-11）、氯氟烃-12（CFC-12）、叶绿素a、碳-13同位素比值（Δ¹³C）、溶解无机碳（DIC）、溶解有机碳、溶解氧、静水压、硝酸盐、硝酸盐+亚硝酸盐含量（浓度）、亚硝酸盐、脱镁叶绿素、磷酸盐、位温（θ）、盐度、西格玛θ（σθ，位势密度）、硅酸盐、总磷、水温以及pH值。采集上述数据所用的仪器包括温盐深仪（CTD）、用于测量溶解无机碳的库仑计以及采水器。本数据集由气象研究所地球化学研究部的石井正男（Masao Ishii）以及志贺达史（Tatsushi Shiga，所属机构不明）作为PACIFICA_49FA20071023数据集的一部分完成采集。
PACIFICA项目（全称为PACIFic ocean Interior CArbon，即太平洋内部碳循环项目）是一项针对太平洋洋内碳循环及其相关参数开展数据综合研究的国际合作项目。北太平洋海洋科学组织（PICES）碳与气候分部（S-CC）为该项目提供了支持。
