Seaweed in the Schleswig-Holstein Wadden Sea 1999-08-16
收藏资源简介:
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 nana and Z. marina are not differentiated. 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.
自1991年起,作为三边监测计划(Trilateral Monitoring Programme, TMAP)的组成部分,开展了海草床航空测绘工作。本次数据集记录了两类封闭海草种群的密度等级。采用运动类航空器开展的海草分布区域识别,仅在覆盖度约25%的情况下才可实现,且未区分矮大叶藻(Zostera nana)和大叶藻(Z. marina)。研究结果依据观测情况标注于地图中,且偏远海草种群的位置误差更大。1989年与1990年开展的类似但存在差异的测绘工作,可在石勒苏益格-荷尔斯泰因州瓦登海的生态系统研究相关项目中获取数据。
