CSIRO Atlas of Regional Seas (CARS) 2006 Bottom Water Oxygen 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 oxygen data is used to show the spatial and temporal variation of oxygen 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，其北向延伸范围仅至北纬10°。该数据集绘制了六项海水参数的空间分布：水温（摄氏度，°C）、盐度（实用盐标，PSU）、溶解氧（毫升/升）、硝酸盐（微摩尔/升）、硅酸盐（微摩尔/升）与磷酸盐（微摩尔/升）。该数据集包含历史平均场与平均季节循环序列，其数据源自所有可获取的历史次表层海洋参数观测资料，主要包括研究船仪器剖面观测数据与自主剖面浮标观测结果。溶解氧数据的标准差被用于表征底层海水中溶解氧的时空变化特征，分析过程中采用了全年每日的全部历史观测数据。本数据集是CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）的贡献成果之一。
