Distribution of Weddell seals pupping at the Vestfold Hills.

The information in the dataset is the location of Weddell seals with pups at the Vestfold Hills. Resolution of locations is 0.63 sq. kilometres because the data are recorded as x-y coordinates of a grid-square map (see metadata record 'Weddell seal reporting grid of the Vestfold Hills, Antarctica', Data Set ID 'Wed-map'). The source of the data are the Australian Antarctic Division TAGS database, Report No. 11 (pups per annum/season - sorted by X and Y). The data consists of counts of tagged pups per grid square summed over 24 years, and also counts of years that each grid square was occupied by one or more pup. The data are expressed as number, percentage of total number, and ratio of number of pups to number of years occupied for each grid square. The total number of pups is 3 795 pups. The total number of years is 24 years. Temporal coverage is 1973-1999 excluding years 1975, 1976, and 1997 because seals were recorded in few grid squares in those years (2, 6, and 0 grid squares respectively). For the other 24 years, the average (+/- standard deviation) number of grid squares occupied per year is 21.5 +/- 6.5 grid squares per year. The average (+/- standard deviation) number of pups born and tagged per year is 158.1 +/- 31.0 pups per year. This and other spatial data for Weddell seals at the Vestfold Hills has been published in ANARE Research Notes 19 (Green et al. 1995) and also in Sam Lake's masters thesis (1995). The fields in this dataset are:GridsquareCountTotalCount/YearCount%Total%

本数据集包含南极洲韦斯特福尔丘陵（Vestfold Hills）地区携带幼崽的威德尔海豹（Weddell seals）的分布位置信息。位置分辨率为0.63平方公里，因数据以方格地图的X-Y坐标形式记录（详见元数据记录《南极洲韦斯特福尔丘陵威德尔海豹报告网格》，数据集ID：Wed-map）。

数据来源为澳大利亚南极局（Australian Antarctic Division）TAGS数据库第11号报告（按X-Y坐标排序的年度/季度幼崽数量）。

数据集内容包括：24年间各网格方格内带标记幼崽数量的累计值，以及各网格方格有1只及以上幼崽出现的年份数量。数据以各网格方格的幼崽数量、占总数的百分比，以及幼崽数量与被占用年份数量的比值三种形式呈现。

幼崽总数为3795只，涉及总年份为24年。时间覆盖范围为1973-1999年，但不包含1975年、1976年及1997年——因这些年份记录到海豹的网格方格数量极少（分别为2个、6个及0个）。其余24年间，每年被占用的网格方格数量平均值（±标准差）为21.5±6.5个/年；每年出生并带标记的幼崽数量平均值（±标准差）为158.1±31.0只/年。

本数据集及韦斯特福尔丘陵地区威德尔海豹的其他空间数据已发表于《ANARE研究通讯》第19期（Green等，1995）及Sam Lake的硕士论文（1995）。

本数据集包含以下字段：Gridsquare（网格方格）、Count（数量）、Total（总计）、Count/Year（年均数量）、Count%（数量占比）、Total%（总计占比）
