This new OOI Data Lab, Changes in Salinity, consists of three sets of activities developed to support students’ understanding of sea surface salinity and variables that affect salinity. Students are introduced to time-series data and are asked to interpret data trends, focusing on sea surface salinity at a single station in the North Pacific Ocean. Other activities examine changes in sea surface salinity and oceanic/atmospheric parameters over time, including data from other OOI arrays. The authors will review the activity and discuss implentation in their courses.
