Temporal variability of the hydrographic changes on the Antarctic continental seas

This dataset contains anomalous timeseries of temperature and salinity profiles over 15 major shelf seas around Antarctica. The base data is generated by removing the spatially-varying climatology from the raw profile compilation used to generate the climatology field. Raw profiles are available at https://doi.org/10.17882/99787 and the climatology product is available at https://www.seanoe.org/data/00928/103946/. The anomaly profiles are binned into a regular spatial grid with 20km spacing, the searching range of each bin is determined by 200 by 200 km square at each grid point. Anomaly profiles are put in ascend time order in each bin. These binned profiles timeseries are subsequently used to construct anomaly profile time series over major continental shelf seas bounded by geographical polygons as illustrated in the displayed figure. This dataset provides a pan-Antarctic survey of observation based temporal variability of temperature and salinity field.

本数据集包含环绕南极洲的15个主要陆架海的温度与盐度廓线异常时间序列。基准数据通过从用于生成该气候态场的原始廓线汇编中移除空间变化的气候态得到。原始廓线可在https://doi.org/10.17882/99787获取，气候态产品可在https://www.seanoe.org/data/00928/103946/获取。异常廓线被分箱至间距为20km的规则空间网格中，每个网格点的分箱搜索范围由200km×200km的正方形区域确定。每个分箱内的异常廓线均按时间升序排列。这些经分箱处理的廓线时间序列随后被用于构建由展示图中地理多边形划定的主要大陆架海的异常廓线时间序列。本数据集提供了基于观测的全南极温度与盐度场时间变率调查。
