HX250 CTD Data [Woodgate, R.]

This is calibrated Conductivity, Temperature, Depth (CTD) downcast data from the Alpha Helix Cruise HX250, a mooring recovery and redeployment cruise during August and September 2001. Data were post calibrated and adjusted to bottle samples by Seth Danielson of the University of Alaska Fairbanks (UAF). These data were collected with a Seabird 911 Plus CTD sampling at 24 frames/second with 2 conductivity and 2 temperature sensors. Temperature is reported as computed with the ITS90 scaling. Salinity offset was determined by applying comparing salinometer results to CTD data.

本数据集为2001年8月至9月开展的锚系回收与重新部署航次——Alpha Helix航次HX250的经校准电导率、温度、深度（Conductivity, Temperature, Depth, 简称CTD）下行剖面数据。数据经后期校准，并由阿拉斯加大学费尔班克斯分校（University of Alaska Fairbanks, 简称UAF）的Seth Danielson根据采水器水样完成校正。该批数据由搭载2个电导率传感器与2个温度传感器的Seabird 911 Plus型CTD系统以24帧/秒的采样率采集得到。温度数据采用ITS-90国际温标进行计算并报告。盐度偏差通过将盐度计测量结果与CTD数据进行比对确定。
