Weddell seal locations in the Rauer Group recorded by the Frozen Sea Expedition of 1982-1984

This is a polygon dataset digitised from a 1982-1984 Frozen Sea Expedition grid map (attached) showing locations where Weddell seals were recorded in the Rauer Group region, Prydz Bay, Antarctica. Weddell seal distribution data were mapped by members of the Oceanic Research Foundation Ltd. in collaboration with Harry Burton and Rhys Puddicombe (ANARE). This work was undertaken during the Frozen Sea Expedition to Prydz Bay which occurred between 1982-1984 and during which the expedition schooner 'Dick Smith Explorer' wintered in the Rauer Group. Locations of seal occurrence were marked on a base map of the Rauer Group on which a grid had been drawn. Data were recorded as 'Late Autumn /early Winter most common seal locations (July to September)' and 'Known pupping locations (October to December)'. The locations as highlighted on the map were digitised by the AADC in 2025 and are attached to this record as polygon data in a GeoPackage.

本数据集为从1982-1984年冰冻海探险队网格地图（随附）数字化得到的多边形数据集，展示了南极洲普里兹湾劳尔群岛区域记录到威德尔海豹（Weddell seal）的点位。威德尔海豹分布数据由海洋研究基金会有限公司（Oceanic Research Foundation Ltd.）成员与哈里·伯顿（Harry Burton）、里斯·帕迪科姆贝（Rhys Puddicombe）（澳大利亚国家南极研究探险队，ANARE）协作绘制。此项工作依托1982-1984年的普里兹湾冰冻海探险队开展，期间探险队纵帆船"迪克·史密斯探索者号"（Dick Smith Explorer）在劳尔群岛越冬。海豹出现点位被标注在带有网格的劳尔群岛底图上，数据分为两类："晚秋/初冬最常见海豹点位（7月至9月）"与"已知产崽点位（10月至12月）"。上述地图中标注的点位由澳大利亚南极数据中心（AADC）于2025年完成数字化，并以GeoPackage格式的多边形数据附于本记录中。
