August 26, 2014Leg 4 of the VISIONS'14 Expedition departed Newport Oregon after a two-day packed mobilization period. The R/V Thompson is once again "loaded to the gills" with cables, junction boxes, instruments and mooring packages to be install
August 24, 2014The 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!
August 21, 2014We 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.
August 19, 2014Over 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.
August 16, 2014The last couple of days have been a whirlwind of ROV dive and deck activity at the Endurance Oregon Offshore site (600 meters depth). As of this evening, we have deployed the Benthic Experiment Package (BEP), Digital Still Camera, and Deep Profi
August 14, 2014Today was an especially exciting day for the Oregon State portion of the Ocean Observatories Initiative, the Endurance Array. Today we delivered the Benthic Experiment Package to the seafloor.
August 13, 2014After the last two legs of the VISIONS '14 cruise, which took place at Slope Base and Axial Seamount, thousands of meters deep in the ocean, Leg 3 is going to take place in relatively shallow water. The Endurance Oregon Offshore site is 600
August 09, 2014When 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.
August 08, 2014Even on successful cruises, there are always unexpected events. In this case, the seafloor cable and profiler mooring sockets wouldn't cooperate, so we began to recover the mooring to diagnose and repair the problem. Work continues, and optimism endures.
August 07, 2014The day was dominated by an epic ROPOS dive to relocate the platforms deployed during yesterday's deck operations, plug them in, and collect samples, finishing up the work at the Axial Base site.
