Shallow Waters

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!
Standing on Two Legs

High Waves, Deep Methane

August 19, 2014

The Golden Spike

August 09, 2014

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.
The Best Laid Plans

August 08, 2014

Even 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.
HPIES and Cake and profilers

August 07, 2014
