CSIRO Atlas of Regional Seas (CARS) 2006 Bottom Water Phosphate 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 phosphate data is used to show the spatial and temporal variation of phosphate 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数据集覆盖全球海洋南部三分之二区域，纬度范围为南纬70°至北纬26°，大西洋海域除外，其北向覆盖范围仅达北纬10°。该数据集涵盖6项海水参数的制图数据：水温（摄氏度，℃）、盐度（实用盐度单位，PSU）、溶解氧（毫升/升，ml/L）、硝酸盐（微摩尔/升，μmol/L）、硅酸盐（微摩尔/升，μmol/L）以及磷酸盐（微摩尔/升，μmol/L）。数据集所包含的历史平均场与平均季节循环序列，均源自所有可获取的历史海洋次表层参数实测资料，主要包括研究船仪器剖面测量数据与自主剖面浮标观测数据。研究团队利用全年每日的全部历史实测数据，以磷酸盐数据的标准差表征底层海水中磷酸盐的时空分布变化特征。本数据集系CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）的贡献数据集。
