Gradients4-TN397-Hyperpro-Profiles_2022-04-15_v1.0

Cruise Name: Gradients 4 , TN397 Vessel: R/V Thompson Funding: Simons Collaboration on Ocean Processes and Ecology (SCOPE) Dataset description: This dataset was collected on the R/V Thompson during the Gradients IV cruise which departed from San Diego, CA and ended in Honolulu, HI. A transect was performed on the 140 degree longitude line from roughly 19 degrees N to 2.5 degrees S before heading to Honolulu. The Satlantic (now Seabird) HyperPro is an in-situ free-fall profiling unit designed to measure the apparent optical properties of the ocean with concurrent measurements of temperature, salinity, chlorophyll and dissolved matter fluorescence, and optical backscattering (a proxy for total particle load). The unit is equipped with one up-looking and one down-looking hyperspectral (350-800nm) radiometer with 10 ± 0.3 nm resolution, a WET Labs ECO-Puck Triplet, and temperature, pressure, and conductivity sensors. It also incorporates a ship-mounted surface (air) hyperspectral radiometer. These data are collated from the vertical profiles. Note that lat/lon was pulled from the Station ID and may not exactly match the ship's cruise log.航次名称：Gradients 4，编号TN397；考察船：R/V汤普森号（R/V Thompson）；资助方：西蒙海洋过程与生态合作项目（Simons Collaboration on Ocean Processes and Ecology, SCOPE）。数据集描述：本数据集采集自R/V汤普森号执行的Gradients IV航次（航次编号TN397），该航次从美国加利福尼亚州圣迭戈出发，最终抵达夏威夷州火奴鲁鲁。科考团队先沿140°经线完成了从北纬19°至南纬2.5°的海洋断面观测，随后前往火奴鲁鲁。Satlantic（现Seabird）HyperPro是一款原位自由下落剖面测量装置，用于测量海洋表观光学特性，同时可同步采集温度、盐度、叶绿素与溶解物荧光数据，以及光学后向散射数据（可作为总颗粒负荷的替代指标）。该装置搭载1台朝上观测和1台朝下观测的高光谱（350-800nm）辐射计，分辨率为10±0.3nm；还配备了WET Labs ECO-Puck Triplet传感器，以及温度、压力和电导率传感器。此外，系统集成了船载地表（大气）高光谱辐射计。上述数据均由垂直剖面观测资料整合得到。请注意：经纬度（lat/lon）信息由站点ID提取所得，可能与船舶航行日志记录的实际位置不完全一致。
