CARS climatology dataset of oceanographic variables in the Southeastern Pacific Ocean

This dataset accompanies the publication titled "Evolution of biogeochemical properties inside poleward undercurrent eddies in the southeast Pacific Ocean". The dataset belongs to the CSIRO project. The CSIRO Atlas of Regional Seas (CARS) is a digital climatology, or atlas of seasonal ocean water properties. It comprises gridded fields of mean ocean properties over the period of modern ocean measurement, and average seasonal cycles for that period. It is derived from a quality-controlled archive of all available historical subsurface ocean property measurements - primarily research vessel instrument casts and autonomous profiling buoys. As data availability has enormously increased in recent years, the CARS mean values are inevitably biased towards the recent ocean state. CARS2009 covers the full global oceans, and includes temperature, salinity, oxygen, nitrate, silicate and phosphate fields. Data time period: 31 12 1940 to 31 05 2009 This repository contains temperature, salinity, oxygen, and nitrate data for the southeastern Pacific Ocean, within the area described in the publication.
