To measure things like ocean surface salinity, or freshwater flux for a patch of ocean water, scientists need the right equipment. One way to collect lots of data from a single point in the ocean is to launch a surface mooring into the water, equipped with all of the necessary oceanographic technology. While at-sea, this mooring and its instrumentation will collect continuous data, allowing scientists to see how things like temperature and salinity from that point have changed over time. Dr. Farrar shows us what that instrumentation looks like and how much equipment can fit one one of these large surface moorings!

Hmm…it looks like things are taking a while to load. Try again?
