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 0112288 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 2005-07-08 to 2005-07-28 and retrieved during cruise PACIFICA_49RY20050708 and RF05-06 Leg.2. 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_49RY20050708 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.

国家海洋数据中心（National Oceanographic Data Center, NODC）收录号0112288包含2005年7月8日至2005年7月28日期间，由“龙翔丸II号”（Ryofu Maru II）科考船执行，于北太平洋、菲律宾海及南太平洋海域，依托航次PACIFICA_49RY20050708与RF05-06第二航段所采集的生物、化学、离散样品、物理及剖面数据。
该数据集涵盖碱度、铵、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、溶解有机碳、溶解氧、静压力、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-theta密度（σθ）、硅酸盐、总磷、水温及pH值。
采集上述数据所用的仪器包括温盐深仪（CTD）、溶解无机碳测量专用库仑计及采水器。本次数据由日本气象厅的Sukeyoshi Takatani与气象研究所地球化学研究部的Masao Ishii共同采集，作为PACIFICA_49RY20050708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）是一项聚焦太平洋海域内部碳循环及其相关参数开展数据整合研究的国际合作项目。北太平洋海洋科学组织（North Pacific Marine Science Organization, PICES）下属碳与气候工作组（Section of Carbon and Climate, S-CC）为该项目提供了资助。
