Emissions of climatically-relevant biogenic volatile organic compounds and greenhouse gases from the central Great Barrier Reef, Australia

This dataset regroups part of the data collected during the first comprehensive baseline survey for the Cooling and Shading subprogram of the Reef Restoration and Adaptation Program (RRAP) that was conducted in the Central Great Barrier Reef, 100km off the coast of Townsville, during the early (December) and late (February) austral summer of 2021-2022. This dataset comprises the sampling time, wind direction, relative humidity, air temperature, dewpoint, light intensity, latitude and longitude measured by a Maximet Gill weather station; sea-surface temperature (SST) and sea-surface salinity (SSS) measured by a vanEssen mini-CTD-Diver , the vertical wind velocity outputted from a Campbell Scientific sonic anemometer as well as the atmospheric and dissolved concentrations of all biogenic volatile organic compounds (BVOCs) and greenhouse gases (GHGs) that were measured using a proton-transfer-reaction quadrupole mass spectrometer (Ionicon) coupled with a cavity ring-down spectrometer (Picarro). The resulting flux estimates of all BVOCs and GHGs, which were determined using a bulk flux approach following the numerical scheme proposed by Johnson et al. (2010), are also provided.

本数据集汇集了大堡礁珊瑚礁修复与适应计划（Reef Restoration and Adaptation Program, RRAP）冷却与遮阳子项目的首次全面基线调查所采集的部分数据，该调查于2021-2022年南半球夏季早期（2021年12月）与晚期（2022年2月），在距汤斯维尔海岸100公里的大堡礁中部海域开展。本数据集包含由Maximet Gill气象站测得的采样时刻、风向、相对湿度、气温、露点、光照强度及经纬度；由vanEssen mini-CTD-Diver测得的海水表面温度（sea-surface temperature, SST）与海水表面盐度（sea-surface salinity, SSS）；Campbell Scientific超声风速仪输出的垂直风速；以及采用质子转移反应四极杆质谱仪（Ionicon）结合腔衰荡光谱仪（Picarro）测得的所有生物源挥发性有机化合物（biogenic volatile organic compounds, BVOCs）与温室气体（greenhouse gases, GHGs）的大气浓度与溶解态浓度。本数据集同时提供了采用Johnson等人（2010）提出的数值方案的整体通量法计算得到的全部BVOCs与GHGs的通量估算结果。
