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 Ryofu Maru II in the North Pacific Ocean, Philippine Sea and South Pacific Ocean fro

NODC Accession 0112287 includes biological, chemical, discrete sample, physical and profile data collected from Ryofu Maru II in the North Pacific Ocean, Philippine Sea and South Pacific Ocean from 2005-01-14 to 2005-02-25 and retrieved during cruise PACIFICA_49RY20050114 and RF05-01. 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 Sukeyoshi Takatani of Japan Meteorological Agency and Masao Ishii of Meteorological Research Institute; Geochemical Research Department as part of the PACIFICA_49RY20050114 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登录号0112287收录了2005年1月14日至2005年2月25日期间，在北太平洋、菲律宾海及南太平洋海域由“Ryofu Maru II（龙翔丸II号）”采集的生物、化学、离散样本、物理及剖面数据，相关数据由PACIFICA_49RY20050114与RF05-01航次获取。
本数据集涵盖的参数包括：碱度（ALKALINITY）、铵（AMMONIUM）、氯氟烃-11（CFC-11）、氯氟烃-12（CFC-12）、叶绿素a（CHLOROPHYLL A）、碳同位素δ¹³C（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，θ）、盐度（SALINITY）、密度距平σ_θ（SIGMA-THETA）、硅酸盐（SILICATE）、总磷（TOTAL PHOSPHORUS）、水温（WATER TEMPERATURE）及酸碱度（pH）。
采集本数据集所用的仪器包括CTD（温盐深仪）、溶解无机碳测定库仑计及采水器。本数据集由日本气象厅的Sukeyoshi Takatani与气象研究所的Masao Ishii及地球化学研究部门作为PACIFICA_49RY20050114数据集的组成部分共同采集完成。

PACIFICA（全称Pacific Ocean Interior Carbon，即太平洋内部碳循环项目）是一项针对太平洋海域内部碳循环及其相关参数开展数据整合的国际合作项目。本项目得到北太平洋海洋科学组织（PICES）碳与气候分会（S-CC）的支持。
