Vertical profiles of environmental parameters measured from physical, optical and imaging sensors during station TARA_041 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 set includes properties of seawater, particulate matter and dissolved matter from physical, optical and imaging sensors mounted on a vertical sampling system (Rosette) used during the 2009-2013 tara Oceans Expedition. It comprised 2 pairs of conductivity and temperature sensors (SEABIRD components), and a complete set of WEtLabs optical sensors, including chrorophyll and CDOM fluorometers, a 25 cm transmissiometer, and a one-wavelength backscatter meter. In addition, a SATLANTIC ISUS nitrate sensor and a Hydroptic Underwater Vision Profiler (UVP) were mounted on the rosette. In the Arctic Ocean and Arctic Seas (2013), a second oxygen sensor (SBE43) and a four frequency Aquascat acoustic profiler were added. The system was powered on specific Li-Ion batteries and data were self-recorded at 24HZ. Sensors have all been factory calibrated before, during and after the four year program. Oxygen was validated using climatologies (WOA09). Nitrate and Fluorescence data were adjusted with discrete measurements from Niskin bottles mounted on the Rosette, and optical darks were performed monthly on board. A total of 839 quality checked vertical profiles were made during the tara Oceans expedition 2009-2013.

塔拉海洋科考航次（2009-2013）依托一艘36米长的纵帆船开展全球海洋采样，收集了环境数据与从病毒到浮游后生动物在内的各类生物样本，以供后续借助现代测序技术与前沿成像技术开展分析。塔拉海洋数据集尤其适合研究浮游生物的遗传、形态与功能多样性。本数据集包含2009-2013年塔拉海洋科考航次中，搭载于垂直采样系统（Rosette）的物理、光学与成像传感器采集的海水、颗粒物与溶解物相关参数。该系统配备两对电导-温度传感器（SEABIRD组件），以及一套完整的WETLabs光学传感器组，涵盖叶绿素与有色溶解有机物（CDOM）荧光计、25厘米透射仪与单波长后散射仪。此外，该采样系统上还搭载了SATLANTIC ISUS硝酸盐传感器与Hydroptic水下视觉剖面仪（UVP）。2013年在北冰洋及北极海域，额外加装了第二台氧气传感器（SBE43）与四频Aquascat声学剖面仪。整套系统由专用锂离子电池供电，数据以24赫兹的频率自主记录。所有传感器均在为期四年的科考项目开展前、中、后期完成原厂校准。氧气浓度数据通过气候学数据集（WOA09）进行了验证。硝酸盐与荧光数据通过搭载于该采样系统的尼斯金采水器（Niskin bottle）采集的离散样本完成校正，且每月在船上开展光学暗场校准。整个2009-2013年塔拉海洋科考航次期间，共计完成839份经过质量校验的垂直剖面采样。
