Data Tips

When the site loads, you are able to see the full dataset of salinity data from the Inshore and Offshore sites of the Coastal Endurance. You can interact with the data by:

Questions for Thought

Orientation Questions
  • For each regional comparison, across what time periods are you able to observe salinity data in this graph?
  • What is the first month and year there are data?
  • What is the last month and year there are data?
Interpretation Questions
  • What similarities and differences did you find in patterns of salinity over time:
    • Between inshore and offshore locations on shelf in temperate North Pacific Ocean locations?
    • Between the Atlantic vs. Pacific Ocean in temperate northern hemisphere locations?
    • Between Northern near-polar vs. Southern temperate in the Atlantic Ocean locations?
  • What other questions do you have about variations in patterns of salinity over time across different parts of the ocean from these data?

The above datasets were downloaded from the OOI data portal, and then down-sampled to hourly intervals. The data presented are from the raw record, that is, they are instantaneous measurements that have not been averaged because that would smooth out the variability in the dataset.
