Fraction of spectral solar irradiance transmitted through snow and sea ice as measured in different depths under sea ice (transmittance) from ROV survey ARTofMELT2023/1_20-3 on 2023-05-20, survey 2@en

Transmitted solar irradiance was measured using an ACC (Advanced-Cosine-Collector) RAMSES hyper-spectral radiometer (TriOS) mounted on the ROV during the ARTofMELT2023 expedition in May and June 2023 and normalized by the incident solar irradiance as measured using an ACC RAMSES hyper-spectral radiometer (TriOS) installed on-board the ship. All times are given in Universal Coordinated Time (UTC).2023年5月至6月的ARTofMELT2023科考航次中，研究人员借助安装于遥控无人潜水器（Remotely Operated Vehicle，ROV）上的先进余弦收集器（Advanced-Cosine-Collector，ACC）型RAMSES高光谱辐射计（TriOS公司），完成了透射太阳辐照度的测量工作；并以安装于科考船甲板的同款ACC RAMSES高光谱辐射计（TriOS公司）所测得的入射太阳辐照度作为参考基准，对上述测量数据进行了归一化处理。所有时间均采用协调世界时（Universal Coordinated Time，UTC）进行标注。
