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 Hokusei Maru in the North Pacific Ocean from 2000-06-01 to 2000-06-15 (NODC Accessio

NODC Accession 0112243 includes chemical, discrete sample, physical and profile data collected from Hokusei Maru in the North Pacific Ocean from 2000-06-01 to 2000-06-15 and retrieved during cruise HO00-1 and PACIFICA_49HO20000601. These data include ALKALINITY, AMMONIUM, DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE + NITRITE CONTENT (CONCENTRATION), NITRITE, PHOSPHATE, SALINITY, SILICATE, WATER TEMPERATURE and pH. The instruments used to collect these data include CTD, Coulometer for DIC measurement and bottle. These data were collected by Shuichi Watanabe of Hokkaido University as part of the PACIFICA_49HO20000601 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0112243数据集涵盖了2000年6月1日至6月15日在北太平洋由“北星丸（Hokusei Maru）”号采集，并在HO00-1航次与PACIFICA_49HO20000601航次中回收的化学、离散样品、物理及剖面数据。该数据集包含碱度（ALKALINITY）、铵（AMMONIUM）、溶解无机碳（DISSOLVED INORGANIC CARBON）、溶解氧、静水压力、硝酸盐+亚硝酸盐含量（浓度）、亚硝酸盐、磷酸盐、盐度、硅酸盐、水温及pH值。采集上述数据所用的仪器包括温盐深剖面仪（CTD）、用于溶解无机碳测量的库仑计（Coulometer）以及采水器（bottle）。本数据集由北海道大学的渡边修一（Shuichi Watanabe）作为PACIFICA_49HO20000601数据集的组成部分完成采集。
PACIFICA（全称为PACIFic ocean Interior CArbon，即太平洋内部碳项目）是一项旨在开展太平洋海洋内部碳及其相关参数数据合成研究的国际合作项目。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。
