Seaweed in the Schleswig-Holstein Wadden Sea 2015-07-23

Aircraft mapping of seagrass meadows since 1991 as part of the Trilateral Monitoring Programme (TMAP). 2 density classes of closed stocks are recorded. The identification of the surfaces from the sports aircraft is only possible from about 25% coverage, Zostera noltii and Z. marina are not distinguished. The results are entered in maps according to the observations, and the positional inaccuracies are greater for remote stocks. Similar, but differing, mappings from 1989 and 1990 are available in the context of ecosystem research in Schleswig-Holstein's Wadden Sea.本数据集为1991年起作为三边监测计划（Trilateral Monitoring Programme, TMAP）组成部分开展的海草床航空测绘成果。本次测绘共记录两类密度等级的封闭海草种群；受观测条件限制，使用运动航空器开展的海草床表面识别仅可在覆盖度约25%及以上的区域实现，且未区分矮大叶藻（Zostera noltii）与大叶藻（Zostera marina）。测绘结果依据原始观测记录绘制为专题地图，偏远海草床的位置定位偏差相对更大。此外，1989年与1990年的同类（存在差异）测绘成果可在石勒苏益格-荷尔斯泰因州瓦登海的生态系统研究项目中获取。
