Underway surface water data during the Tara Oceans expedition in 2013@en
收藏资源简介：
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. During the entire expedition (2009-2013), underway measurements were obtained from a meteorological station (BATOS), a thermosalinograph (TSG, SBE 45), a Fast Repetition Rate Flurometer (FRRF, LIFT-FRR01), and a spectrophotometer (WETLabs AC-S). In 2013 underway measurements were enhanced by adding a Photosynthetically Available Radiation (PAR) sensor (QCP2350, Biospherical Instruments, Inc.), a laser spectrofluorometer (WETLabs ALFA, Chekalyuk et al., 2012) that replaced the FRRF, a spectral backscattering sensor (WETLabs Eco-bb3), a pCO2 sensor (ProOceanus CO2-Pro), a pH sensor (Satlantic, SeaFET) and a particle imaging system triggered by chlorophyll-a fluorescence (a prototype of McLane Research Laboratories' Imaging FlowCytobot, Sosik Lab, WHOI). Discrete measurements of CDOM absorption measurements were made using an Ultrapath (WPI Inc.) to calibrate the in-line AC-S. Hence the AC-S was also used to provide CDOM absorption in addition to particulate matter properties. […]
塔拉海洋科考航次（Tara Oceans Expedition，2009-2013）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生物的各类生物体样本与环境数据，后续将通过现代测序技术与前沿成像技术开展相关分析。塔拉海洋数据集尤其适用于研究浮游生物的遗传、形态与功能多样性。在整个航次周期（2009-2013）内，科考船搭载的气象站（BATOS）、温盐计（TSG，SBE 45）、快速重复速率荧光计（Fast Repetition Rate Flurometer，FRRF，LIFT-FRR01）以及分光光度计（WETLabs AC-S）完成了全流程走航测量。2013年，走航测量系统得到升级：新增光合有效辐射（Photosynthetically Available Radiation，PAR）传感器（QCP2350，碧陆科学仪器公司（Biospherical Instruments, Inc.））、激光荧光光谱仪（WETLabs ALFA，Chekalyuk等，2012）以替代原FRRF设备、光谱后向散射传感器（WETLabs Eco-bb3）、pCO₂传感器（ProOceanus CO2-Pro）、pH传感器（Satlantic SeaFET），以及一套基于叶绿素-a荧光触发的粒子成像系统——该系统为麦克莱恩研究实验室（McLane Research Laboratories）成像流式细胞仪（Imaging FlowCytobot）的原型机，由伍兹霍尔海洋研究所（WHOI）索西克实验室（Sosik Lab）研发。研究人员采用Ultrapath（WPI公司）开展有色溶解有机物（Colored Dissolved Organic Matter，CDOM）吸收的离散测量，以校准在线AC-S设备。因此，AC-S设备除可获取颗粒物特性数据外，还可用于提供有色溶解有机物的吸收光谱数据。[…]
