CSIRO Atlas of Regional Seas (CARS) 2006 Bottom Water Nitrate 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 nitrate data is used to show the spatial and temporal variation of nitrate 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，其北界仅延伸至北纬10°。该数据集共展示六项海洋水文要素的空间分布：温度（摄氏度，℃）、盐度（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）与磷酸盐（微摩尔/升，μmol/L）。数据集包含历史平均场与平均季节循环序列，其数据来源于所有可获取的历史海洋次表层水文要素观测资料，主要包括科研船舶仪器观测剖面与自主式剖面浮标数据。本数据集以硝酸盐数据的标准差为指标，结合全年每日的全部历史观测资料，用以呈现底层水体中硝酸盐的时空变化特征。本数据集系CERF海洋生物多样性中心（CERF Marine Biodiversity Hub）的贡献成果。
