Six Barny moorings containing acoustic Doppler current profilers (ADCPs) and wave/tide gauges are safely lashed to the deck of the Seward Johnson II. These moorings survived the wrath of Hurricane Ivan in the Gulf of Mexico. The moorings, which resemble barnacles and hence called Barnys, were deployed by the Naval Research Laboratory on the ocean bottom at depths ranging between 60 and 90 m. Their shape provided a trawl resistance in order to survive frequent trawling by fishermen in the Gulf. The moorings collected the most comprehensive set of current and wave measurements ever made beneath a category 4 storm. Currents in excess of 2 m/s were measured and a record wave of 91 ft was recorded. Credit: William J. Teague, Naval Research Laboratory
