KM2112 SCOPE-PARAGON-1 cruise, Wirewalker

This dataset was collected during the 2021 SCOPE-PARAGON-1 cruise. This cruise was directed towards understanding the processes and rates of biological particulate matter transformations (e.g., production, decomposition, sinking) as well as the ecological interactions that occur in association with suspended and sinking particles. These targeted studies of particle dynamics at Station ALOHA leveraged ongoing ecological and biogeochemical modeling efforts in SCOPE. The Wirewalker is a wave-powered drifting profiler designed to collect autonomous, vertically-resolved oceanographic observations. The profiler moves along a wire that is suspended between a float at the sea surface and a weight placed at a depth of tens or hundreds of meters. The system horizontal displacement follows the ocean currents. Wirewalker measurements include temperature, salinity, depth, beam attenuation, backscattering, chlorophyll fluorescence, CDOM fluorescence, downwelling irradiance in four spectral bands, and dissolved oxygen concentration.本数据集采集于2021年SCOPE-PARAGON-1航次。本次航次旨在解析生物颗粒物转化（如产生、分解、沉降）的过程与速率，以及与悬浮颗粒物和沉降颗粒物相关的生态相互作用。本次针对ALOHA站（Station ALOHA）颗粒物动力学的靶向研究，依托了SCOPE项目中已开展的生态与生物地球化学建模工作。波浪驱动漂移剖面仪（Wirewalker）是一款专为采集自主式垂直分层海洋观测数据而设计的设备。该剖面仪沿一根绳索移动，绳索一端悬挂于海面浮标，另一端悬挂于数十至数百米深度的重物处。该系统的水平位移随海流而动。Wirewalker的观测参数包括温度、盐度、深度、光束衰减系数、后向散射强度、叶绿素荧光、有色溶解有机物（CDOM）荧光、四个光谱波段的下行辐照度以及溶解氧浓度。
