Mawson Temperature and Salinity Data

This dataset contains temperature and salinity data from CTD observations at Mawson, Antarctica. Profiles to 370m were attempted on an approximately monthly basis between October 1980 and October 1982. A representative value for each month of the year has been obtained during this 2 year period.The fields in this dataset are:observation_date (the date of observation, in ISO8601 format yyyy-mm-ddTHH:MM:SSZ. This information is also separated into the year, month, day, etc components) observation_date_year (the year of the observation date) observation_date_month (the month of the observation date) observation_date_day (the day of the observation date) depth (the depth at which measurements were made in m) temperature (the measured water temperature in degrees C) salinity (the measured salinity in ppt) sigma_t (kgm^-3)

本数据集收录了南极洲莫森站（Mawson）的温盐深仪（CTD，Conductivity-Temperature-Depth）观测所得的水温与盐度数据。1980年10月至1982年10月期间，以近似月度为间隔尝试采集深度可达370米的水体剖面数据；在此两年的观测周期内，已获取该年度各月的代表性观测数值。本数据集包含以下字段：
1. observation_date：观测日期，采用ISO8601格式，格式为yyyy-mm-ddTHH:MM:SSZ，该日期信息同时拆分为年、月、日等独立组分
2. observation_date_year：观测日期对应的年份
3. observation_date_month：观测日期对应的月份
4. observation_date_day：观测日期对应的日期
5. depth：测量时的水深，单位为米（m）
6. temperature：实测水体温度，单位为摄氏度（℃）
7. salinity：实测水体盐度，单位为ppt
8. sigma_t：单位为千克每立方米（kg·m⁻³）
