CSIRO Atlas of Regional Seas (CARS) 2006 Bottom Water Salinity Data Standard Deviation

CARS2006 spans the southern 2/3 of the worlds oceans, from 70S to 26N, except in the Atlantic where is reaches only to10N. The six water properties mapped in are temperature (deg C), salinity (PSU), oxygen (ml/litre), nitrate (micromole/litre), silicate (micromole/litre), phosphate (micromole/litre). It comprises historic mean fields and average seasonal cycles, derived from all available historical subsurface ocean property measurements (primarily research vessel instrument casts and autonomous profiling buoys). The standard deviation for the salinity data is used to show the spatial and temporal variation of salinity in the bottom water utilising all of the historical data for each day of the year. This dataset is a contribution to the CERF Marine Biodiversity Hub.CARS2006 覆盖全球海洋南部三分之二的区域，纬度范围为南纬70°至北纬26°，仅大西洋海域除外，其北向延伸仅达北纬10°。该数据集共测绘六项海水要素：温度（单位：摄氏度，℃）、盐度（实用盐度单位，PSU）、溶解氧（单位：毫升/升）、硝酸盐（单位：微摩尔/升）、硅酸盐（单位：微摩尔/升）与磷酸盐（单位：微摩尔/升）。其数据源自所有可获取的历史海洋次表层要素观测资料，主要包括科研船舶仪器剖面测量数据与自主剖面浮标观测数据，涵盖历史平均场与平均季节循环序列。研究团队利用全年每日的全部历史观测数据，通过盐度数据的标准差来表征底层水体盐度的时空变化特征。本数据集为CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）的贡献成果之一。
