A new way of measuring microstructure
By Matthew Alford This whole project is called the Boundary Layer Turbulence experiment, a name which might provoke the question, “How do we actually measure turbulence in the ocean?” Generally, the tried-and-true way is to use tiny sensing elements called piezoelectric beams. These output a voltage when they are deflected, just like the needle on…
OTIS
Injecting tracer into the bottom of the ocean appears to be a rather straightforward operation. However, the procedures were more complex than one might imagine. The sled is an Ocean Tracer Injection System (aptly named OTIS) that is run by Marie-Jose Messias from the University of Exeter tracer release team on board RRS Discovery. It…
There’s Mooore to Moorings than you think!
Moorings are diverse and robust structures that are specifically tailored for each oceanographic experiment. In the previous blog post you learned a bit about our moored profiler and the feats that it can accomplish all on its own down near the bottom of the ocean. For our Boundary Layer Turbulence experiment we designed and deployed…
