CSIRO Atlas of Regional Seas (CARS) 2006 Bottom Water Silicate Data Mean

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 mean refers to the long-term average of silicate in the bottom water at each location. This dataset is a contribution to the CERF Marine Biodiversity Hub.CARS2006数据集覆盖全球海洋南三分之二区域，纬度范围为南纬70°至北纬26°，大西洋海域除外——其在大西洋仅延伸至北纬10°。该数据集共涵盖6项被映射的海水物理化学参数：水温（摄氏度）、盐度（PSU，实用盐度单位）、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）。其包含历史平均场与平均季节循环序列，数据源自所有可获取的历史次表层海水参数实测资料，主要包括科研船舶仪器观测剖面与自主剖面浮标数据。此处的平均值特指各站位底层水中硅酸盐的长期平均值。本数据集为CERF海洋生物多样性枢纽（CERF Marine Biodiversity Hub）的贡献项目。
