Sea surface temperature (SST) measurements at different depths and auxiliary environmental data collected at 62 stations on AMT28 (JR18001) using the Simple Oceanographic floating Device (SOD) and Infrared SST Autonomous Radiometer.

This dataset consists of sea surface temperature (SST) measurements collected from a range of instruments, at slightly different depths, at 62 stations during the 28th Atlantic Meridional Transect (AMT28/JR18001) research cruise (September and October 2018) on the RRS James Clark Ross (JCR). The data includes sea surface temperature (SST) measurements collected from a Smartfin (internal and external sensors) at approximately 0.1 m, and SST data at 1 m collected from TidbiT v2 and iButton sensors, which were calibrated to an NPL-traceable Hart Scientific 1504 temperature bridge and Themometrics ES 225 temperature probe. These sensors were mounted to a Simple Oceanographic floating Device (SOD) and deployed for approximately 20 minutes at each station. Additionally, the dataset includes SST skin measurements from an Infrared Sea surface temperature Autonomous Radiometer (ISAR) and SST data at 5 m collected from the ship's underway system using a Seabird SBE38 sensor. Auxiliary environmental data (air temperature, photosynthetically available radiation (PAR), and wind speed) collected from the ship's underway system and from a Gill Windmaster mounted on the foremast of the ship are included. Median and robust standard deviations (SDV) of all variables are provided over the duration of the SOD deployments at each station. The European Space Agency is acknowledged for their funding and contributions to the collection of the ISAR data on AMT28.

本数据集收录了2018年9月至10月期间，在RRS詹姆斯·克拉克·罗斯号（RRS James Clark Ross, JCR）执行第28次大西洋经向断面（Atlantic Meridional Transect, AMT28/JR18001）科考航次中，于62个站位采用不同深度仪器采集的海面温度（sea surface temperature, SST）测量数据。本数据集包含约0.1米深度处由Smartfin（内置及外置传感器）采集的海面温度数据，以及1米深度处由TidbiT v2与iButton传感器采集的海面温度数据；上述传感器均经可溯源至英国国家物理实验室（National Physical Laboratory, NPL）的Hart Scientific 1504温度校准桥及Themometrics ES 225温度探头完成校准。这些传感器被安装于简易海洋学浮标装置（Simple Oceanographic floating Device, SOD），并在每个站位部署约20分钟。此外，本数据集还包含由红外海面温度自主辐射计（Infrared Sea surface temperature Autonomous Radiometer, ISAR）采集的海面表皮温度数据，以及采用Seabird SBE38传感器、通过船载走航系统采集的5米深度海面温度数据。本数据集同时收录了由船载走航系统及安装于船舶前桅的Gill Windmaster采集的辅助环境数据，包括气温、光合有效辐射（photosynthetically available radiation, PAR）及风速。本数据集提供了每个站位浮标装置部署期间所有变量的中位数及稳健标准差（robust standard deviations, SDV）。感谢欧洲空间局（European Space Agency）为本航次AMT28的ISAR数据采集工作提供资金支持与技术贡献。
