Properties of seawater from a Sea-Bird TSG temperature and conductivity sensor mounted on the continuous surface water sampling system during campaign TARA_20091019Z of the Tara Oceans expedition 2009-2013

The Tara Oceans Expedition (2009-2013) sampled the world oceans on board a 36 m long schooner, collecting environmental data and organisms from viruses to planktonic metazoans for later analyses using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data publication contains measurements from the Continuous Surface Sampling System [CSSS] made during one campaign of the Tara Oceans Expedition. Water was pumped at the front of the vessel from ~2m depth, then de-bubbled and circulated to a Sea-Bird TSG temperature and conductivity sensor. System maintenance (instrument cleaning, flushing) was done approximately once a week and in port between successive legs. All data were stamped with a GPS.

塔拉海洋科考航次（Tara Oceans Expedition，2009-2013年）依托一艘长36米的纵帆船对全球海洋开展采样工作，采集了从病毒到浮游后生动物的各类生物样本与环境数据，以供后续借助现代测序技术与前沿成像技术开展分析研究。塔拉海洋（Tara Oceans）数据集尤其适用于探究浮游生物的遗传、形态与功能多样性。本次公开数据集包含塔拉海洋科考航次单次巡航期间由连续表层采样系统（Continuous Surface Sampling System, CSSS）获取的测量数据。研究人员在船体前部从约2米深度抽取海水，经除泡处理后将水流导入Sea-Bird TSG温度与电导率传感器。系统维护（含仪器清洁与冲洗）工作约每周开展一次，并会在相邻航次间隙的停靠港口进行。所有数据均标注有GPS定位时间戳。
