Hyperspectral underwater light field measured during the cruise SO245 with RV SONNE

Data presented here were collected during the cruise SO245 with RV SONNE from Antofagasta, Chile to Wellington, New Zealand (December 17th, 2015 - January 28, 2016). In total, 15 underwater light profiles were collected at 15 stations, using a free-falling hyperspectral light profiler. The system used was a SEABIRD HyperPro II (SN 099, former Satlantic), equipped with a irradiance sensor to measure downwelling irradiance (Ed, SN 262) and a radiance sensor for upwelling radiance (Lu, SN 227). A reference unit was attached to the ship to measure the above water irradiance (Es, SN 223). The sensors were pre-calibrated by the manufacturer and validated prior to the cruise with a reference lamp. Data were recorded with the SatView software (V 2.9.5_7) and processed from raw to Level1, 1b, 2, 2s to Level 3a using the ProSoft Processing software (V 7.7.19_2). Measured data were binned in 1 m depth intervals. […]

本数据集所呈现之资料，系于SO245航次期间，由智利安托法加斯塔至新西兰惠灵顿的RV SONNE航行过程中采集（2015年12月17日至2016年1月28日）。总计在15个站点收集了15个水下光强分布剖面，采用自由落体式高光谱光强剖面仪完成。所使用之系统为SEABIRD HyperPro II型（序列号099，前属Satlantic公司），配备有辐照度传感器以测量下行辐照度（Ed，序列号262）及辐射传感器以测量上行辐射（Lu，序列号227）。同时，一参考单元被安装在船上，用以测量水面以上辐照度（Es，序列号223）。传感器由制造商预先校准，并在航次前使用参考灯进行验证。数据记录于SatView软件（版本2.9.5_7）中，并利用ProSoft Processing软件（版本7.7.19_2）从原始数据处理至Level 1、1b、2、2s直至Level 3a。测量数据以1米深度间隔进行分组。
