BACKGROUND
The current distribution of spp. seagrass meadows along the Bulgarian Black Sea coast was studied. We used a combination of historical and recent observations of the habitat along the studied coastline. Remote sensing data (satellite images, sonar side-scans) was groundtruthed with georeferenced drop camera observations, scuba diving sampling and georeferenced scuba diving photo and video transects.
NEW INFORMATION
Тhe total area of the habitat type 'MB548 - Black Sea seagrass meadows on lower infralittoral sands' (EUNIS habitat type list 2019) in the study area is 916.9 ha, of which only 17.9 ha are in man-made sheltered environments (harbours). All seagrass meadows identified in 1978-79 were also located during the current survey, despite the increased eutrophication pressure and overall degradation of benthic habitats in the western Black Sea during the 1980s and early 1990s.
背景
对保加利亚黑海沿岸海草草甸的当前分布情况进行了研究。我们结合了对研究海岸线沿线栖息地的历史观测和近期观测。利用地理参考的投落式相机观测、水肺潜水采样以及地理参考的水肺潜水照片和视频样带对遥感数据（卫星图像、声呐侧扫）进行了实地验证。
新信息
研究区域内“MB548 - 低亚潮带沙地的黑海海草草甸”（2019年欧洲环境信息与观测网络栖息地类型列表）这一栖息地类型的总面积为916.9公顷，其中仅有17.9公顷位于人工遮蔽环境（港口）中。尽管在20世纪80年代和90年代初黑海西部富营养化压力增加且底栖生境总体退化，但在1978 - 1979年确定的所有海草草甸在本次调查中也都被找到了。
