Consider CTD profiles shown below from the Arctic Ocean. Station 18 and 21 was occupied 7 days later than station 18. How can you tell what time of year these profiles were gathered? What is a likely explanation for the changes of temperature and salinity that are observed? Describe the physical processes in detail and how these changes come about.
