The end of Leg 3 is approaching rapidly, and we successfully met every goal for this leg of the VISIONS14 expedition, including some originally scheduled for Leg 2. We’ll be back in Newport by morning. On to Leg 4!
We have another first to report: the first deployment of a two-legged shallow profiler mooring at the Endurance Oregon Offshore site! The mooring operations were smooth, safe, and ultimately a complete success, thanks to a remarkable run of calm weather.
Over the last few days, while waiting for the weather to improve, we spent nights doing water sampling and one extremely long sonar survey, and ROPOS Dive 1750 went to Hydrate Ridge, where methane gas naturally bubbles out of the sediment.
When construction of the Transcontinental Railroad was completed in the 1800s, a golden spike was hammered in to officially link the two coasts of the country. During dive R1741 last night we witnessed the ROV making a similarly historic connection.
