Today is a very busy day with a lot of deployments of different types of equipment. Before daybreak we deployed a wirewalker, an instrument that moves with the currents while profiling up and down to observe the upper water column. Its up and down motion is powered by the waves! It measures the flow velocity as well as the temperature, salinity, and biological variables. We hope that this will complement our many surveys by showing us how the properties of the flow evolve as we follow the front.
