Properties of seawater from a Sea-Bird TSG temperature and conductivity sensor mounted on the continuous surface water sampling system during campaign TARA_20091214Z 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.

塔拉海洋远征（Tara Oceans Expedition，2009-2013年）依托一艘36米长的纵帆船对全球海洋开展采样工作，收集了从病毒到浮游后生动物的各类生物样本与环境数据，以供后续利用现代测序技术与最先进成像手段开展分析。塔拉海洋数据尤其适用于研究浮游生物的遗传、形态与功能多样性。本次发布的数据集包含塔拉海洋远征某次科考航次中连续表层采样系统（Continuous Surface Sampling System，CSSS）获取的测量数据。研究人员在船体前部约2米水深处抽取海水，经脱气泡处理后输送至Sea-Bird TSG温盐传感器进行检测。系统维护（仪器清洁、冲洗）约每周开展一次，并在相邻航段间隙的港口停靠期间完成。所有数据均附带GPS时间戳。
