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.本数据集配套于题为《东南太平洋极向潜流涡旋内部生物地球化学特性演化》的学术论文，隶属于澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）项目。 澳大利亚联邦科学与工业研究组织区域海图集（CSIRO Atlas of Regional Seas, CARS）是一套数字化海洋气候图集，同时也是季节性海洋水特性专题图集。该图集包含现代海洋观测时段内的网格化海洋特性平均场，以及该时段内的平均季节循环特征。其数据源自经过质量控制的所有可用历史次表层海洋特性观测档案，主要包括科研船仪器剖面测量数据与自主式剖面浮标观测数据。由于近年来观测数据的可得性大幅提升，CARS的平均值不可避免地更偏向于近期的海洋状态。CARS2009覆盖全球完整海域，包含温度、盐度、溶解氧、硝酸盐、硅酸盐及磷酸盐要素场。 数据时间范围：1940年12月31日至2009年5月31日 本存储库包含论文所述研究区域内东南太平洋海域的温度、盐度、溶解氧及硝酸盐数据。
