Weddell seals observed in the Bunger Hills during an ANARE expedition in 1986

Data derived from descriptions in a report: "ANARE, Bunger Hills, Preliminary Scientific And Field Operation Report, January - March 1986".The dataset contains one polygon where weddell seals were sighted in the Bunger Hills, covering the areas as described in the report 'ANARE, Bunger Hills, Preliminary Scientific And Field Operation Report, January - March 1986'. The areas described in the report is quite large, therefore the best method is the creation of one polygon covering a larger area, with the input from AAD scientist John van den Hoff.Page 36 of report, under a weddell seals heading: "Approximately 20 is estimated as the population of the area south of Charncokite peninsula and Thomas Island, the area most frequently covered by aircraft." Charncokite peninsula is officially called Booth peninsula.Page 103 of report: "On a flight to mobile 2 at Thomas Island I spotted at least 10 Weddell seals on the sea ice near the Thomas Island and Fishtail Bay areas." Rybij Khvost Gulf is unofficially known as Fishtail Bay.Page 105 of report: "Three weddell seals sighted Kachalot Island and two Weddells sighted south of Kachalot Island. Rod Ledingham flew to Dobrowolski in the afternoon with some equipment that had been left tied to the skids of the aircraft by party 3 and also flew along the coast of the east of the Bunger Hills looking for vehicular access across the sea ice from the plateau. An area was found to the east of Kachalot island. Approximately 10 Weddell seals were sighted on the sea ice during the course of this."Kashalot/Kachalot island is officially called Fuller island.

本数据集的数据源自报告《ANARE, 邦杰丘陵（Bunger Hills）1986年1-3月初步科学与野外作业报告》中的相关描述。该数据集包含一处多边形区域，对应威德尔海豹（Weddell seals）在邦杰丘陵的目击点位覆盖范围，其范围依据上述1986年报告中的记载划定。鉴于报告中描述的区域规模较大，结合澳大利亚南极分部（Australian Antarctic Division, AAD）科学家约翰·范·登·霍夫（John van den Hoff）的专业意见，最优方案为创建一处覆盖较大范围的单一多边形。报告第36页在"威德尔海豹"章节下记载："查诺克半岛与托马斯岛以南区域的威德尔海豹种群数量约为20头，该区域也是航空观测频次最高的区域。"查诺克半岛（Charncokite peninsula）的官方正式名称为布斯半岛（Booth peninsula）。报告第103页记载："在飞往托马斯岛（Thomas Island）的移动站点2的飞行途中，我在托马斯岛与鱼尾湾（Fishtail Bay）附近的海冰上观测到至少10头威德尔海豹。"雷布伊赫沃斯特湾（Rybij Khvost Gulf）的非官方称谓为鱼尾湾。报告第105页记载："在卡查洛特岛周边目击到3头威德尔海豹，在该岛以南区域目击到2头威德尔海豹。罗德·莱丁汉姆（Rod Ledingham）当日下午驾驶飞机飞往多布罗沃尔斯基（Dobrowolski），运送了第三科考队遗留并系在飞机滑橇上的设备，同时沿邦杰丘陵东海岸飞行，寻找从南极高原穿越海冰的车辆通行路线，最终在卡查洛特岛以东区域发现了可行路线。本次飞行期间，在海冰上共观测到约10头威德尔海豹。"卡查洛特岛（Kashalot/Kachalot Island）的官方正式名称为富勒岛（Fuller island）。
