Your Objective

Use salinity data from the surface to 100m from the North Atlantic Ocean to look if there are patterns over time.

Data Tips

When the site loads, you are able to see daily profiles of salinity data from all of May 2015 from the Coastal Pioneer Array. You can interact with the data by:

As a note, the color denotes the time of year the salinity data are from (light purple/pink are from May 2015 through blue/dark purple from February 2016).

Questions for Thought

Orientation Questions
  • Across what time periods are you able to observe salinity with depth data in this graph?
  • What is the first month and year there are data?
  • What is the last month and year there are data?
  • What is the overall range of salinity data you are able to observe in this graph?
Interpretation Questions
  • What changes or patterns did you observe in salinity with depth over this time period in the Northern Atlantic Ocean?
  • When did you see these changes or patterns?
  • What questions do you still have about changes in salinity from the surface to down in the water column over time?

Dataset Information

The data for this activity was obtained from the following profiling CTD instrument:

Download this Dataset

The above datasets were downloaded from the OOI data portal. Complete profiles of the instrument were identified and the profile closest to midnight (GMT) each day was saved. This reduced the overall temporal resolution (and size) of the final dataset but it preserved the raw variability exhibited in individual profiles and measurements.
