The Gulf of Carpentaria and Torres Strait in north-eastern Australia support globally significant seagrass ecosystems that underpin fishing and cultural heritage of the region. Reliable data on seagrass distribution are critical to understanding how these ecosystems are changing, while managing for resilience. Spatial data on seagrass have been collected since the early 1980s, but the early data were poorly curated. Some was not publicly available, and some already lost. We validated and synthesized historical seagrass spatial data to create a publicly available database. We include a site layer of 48,612 geolocated data points including information on seagrass presence/absence, sediment, collection date, and data custodian. We include a polygon layer with 641 individual seagrass meadows. Thirteen seagrass species are identified in depths ranging from intertidal to 38 m below mean sea level. Our synthesis includes scientific survey data from 1983 to 2022 and provides an important evidence base for marine resource management.

1983 年至 2022 年澳大利亚东北部、托雷斯海峡和卡奔塔利亚湾海草空间数据合成

澳大利亚东北部的卡奔塔利亚湾和托雷斯海峡支持着全球重要的海草生态系统，支撑着该地区的渔业和文化遗产。有关海草分布的可靠数据对于了解这些生态系统如何变化以及管理恢复能力至关重要。自 20 世纪 80 年代初以来，人们一直在收集海草的空间数据，但早期数据的整理很差。有些尚未公开，有些已经丢失。我们验证并综合了历史海草空间数据，以创建一个公开可用的数据库。我们包括 48,612 个地理定位数据点的站点层，包括有关海草存在/不存在、沉积物、收集日期和数据保管人的信息。我们包括一个包含 641 个独立海草草地的多边形图层。在潮间带至平均海平面以下 38 m 的深度范围内发现了 13 种海草。我们的综合包括 1983 年至 2022 年的科学调查数据，为海洋资源管理提供了重要的证据基础。
