Dissolved inorganic carbon, total alkalinity, phosphate, silicate, and other variables collected from profile and discrete sample observations using CTD, Niskin bottle and other instruments in the northwest coast of the United States near the Cha Ba mooring off La Push, Washington from 2011-05-22 t

This data set represents validation samples for moored time-series observations of ocean acidification water chemistry. This data set includes temperature and salinity data from CTD sensors and dissolved inorganic carbon concentration, total alkalinity, and nutrient data from Niskin bottle samples collected at the same times and places. Samples were collected on eight cruises conducted between May 2011 and October 2014 on various vessels to service the Cha Ba ocean acidification mooring off La Push, Washington. This data set is a subset of a larger data set of observations collected from Washington coastal waters, in the Strait of Juan de Fuca, and within Puget Sound that will be submitted to NCEI in the future. The larger data set spans the time window of February 2008 to October 2014.

本数据集为海洋酸化水体化学锚定时间序列观测的验证样本集。本数据集包含温盐深传感器（CTD）测得的温度与盐度数据，以及同期同站位尼斯金采水器（Niskin bottle）样品获取的溶解无机碳浓度、总碱度与营养盐数据。样本采集工作依托多艘科考船，于2011年5月至2014年10月间完成8个航次的作业，用于维护华盛顿州拉普什（La Push）海域外的Cha Ba海洋酸化锚系观测系统。本数据集是一套更大规模观测数据集的子集，该数据集采集自华盛顿州近岸海域、胡安·德富卡海峡（Strait of Juan de Fuca）及普吉特海湾（Puget Sound），后续将提交至国家环境信息中心（National Centers for Environmental Information, NCEI）。该大规模数据集的时间覆盖范围为2008年2月至2014年10月。
