Airborne, satellite and ground imaging spectroscopy data for estimation of chlorophyll content, leaf density and relative vigour of Antarctic mosses at ASPA 135 and Robinson Ridge study sites

Research sites All remote sensing data sets were collected at two pilot research sites, Antarctic Specially Protected Area 135 (ASPA) and Robinson Ridge (Robbos), that host significant populations of Antarctic moss species, particularly: Schistidium antarctici (Cardot) L.I. Savicz and Smirnova, Bryum pseudotriquetrum (Hedw.) Gaertn., Meyer and Scherb., and Ceratodon purpureus (Hedw.) Brid. Verification of remote sensing products was performed with data from a long-term monitoring project of Windmill Islands' plant communities using observations of 13 permanent quadrats, which were established at ASPA and Robbos in 2003 (Wasley et al., 2012). Laboratory spectral and biochemical measurements for training of predictive machine leaning algorithms were performed on moss samples collected in the vicinity of the Casey polar station in 2013 and previously in 1999 (Lovelock and Robinson, 2002).

研究基地
所有遥感数据集均收集于两个试点研究基地，即南极特别保护区135号（ASPA）和罗宾逊脊（Robbos），这些基地栖息着大量的南极苔藓物种，尤其是：Schistidium antarctici (Cardot) L.I. Savicz 和 Smirnova，Bryum pseudotriquetrum (Hedw.) Gaertn., Meyer 和 Scherb.，以及 Ceratodon purpureus (Hedw.) Brid. 遥感产品的验证是通过长期监测项目中的数据进行的，该项目监测了风车岛植物群落，并使用13个永久样方在ASPA和Robbos进行观测，这些样方建立于2003年（Wasley等人，2012年）。预测机器学习算法的训练是在2013年在凯西极地站附近收集的苔藓样本以及之前在1999年的实验室光谱和生化测量数据上完成的（Lovelock 和 Robinson，2002年）。
