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 1997-07-11 to 1997-08-11 (NODC Accessio

NODC Accession 0112236 includes chemical, discrete sample, physical and profile data collected from Hokusei Maru in the North Pacific Ocean from 1997-07-11 to 1997-08-11 and retrieved during cruise HO97-3 and PACIFICA_49HO19970711. These data include ALKALINITY, AMMONIUM, DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, 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_49HO19970711 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0112236（NODC Accession 0112236）包含1997年7月11日至1997年8月11日期间，在北太平洋由北斗丸号（Hokusei Maru）收集，并通过航次HO97-3与PACIFICA_49HO19970711获取的化学、离散样本、物理及剖面数据。该数据集涵盖碱度(ALKALINITY)、铵盐(AMMONIUM)、溶解无机碳(DISSOLVED INORGANIC CARBON)、溶解氧(DISSOLVED OXYGEN)、静水压(HYDROSTATIC PRESSURE)、硝酸盐(NITRATE)、亚硝酸盐(NITRITE)、磷酸盐(PHOSPHATE)、盐度(SALINITY)、硅酸盐(SILICATE)、水温(WATER TEMPERATURE)以及pH值。采集这些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)。上述数据由北海道大学的渡边修一（Shuichi Watanabe）收集，作为PACIFICA_49HO19970711数据集的一部分。

PACIFICA（太平洋内部碳项目，全称PACIFic ocean Interior CArbon）是一项针对太平洋海域海洋内部碳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）下属碳与气候分会（S-CC）为该项目提供了支持。
