Back to the barn // TTIDE ends in Hobart port

The R/V Revelle has headed “back to the barn” and has just docked in Hobart, Tasmania. All hands on deck are now in the usual post-cruise full-court-press to get all the remaining scientific gear packed, off the ship, and into containers for the return journey. It’s a morning of mixed emotions, we’re all happy to be back in port and … Read More

Good morning from the Tasman Sea

Good morning! The daytime watch awoke to a spectacular sunrise here aboard the R/V Revelle, stationed about 40 kms off southeastern Tasmania. All 14 moorings are aboard and we have been settling in for the final few days of ocean observations. We have 48 hours left on this final leg and the TTIDE team is making as many “yoyo” and … Read More

T-TIDE student profile: Madeleine Hamann

PhD student Madeleine Hamann from the Scripps Institution of Oceanography is aboard the R/V Revelle for the T-TIDE leg 3 cruise and here she talks about her work and how studying math, science, and engineering has opened up a world of opportunity for her.

The final countdown

The Final Countdown It’s the second weekend out here on the Tasman Sea for the TTIDE leg 3 crew aboard the R/V Revelle. Today we are pushing hard to finish recovering all four remaining moorings still in the water.  If the team can make all that happen before darkness falls tonight that will keep the TTIDE project ahead of schedule … Read More

A day at mooring site “A1”

Chief Scientist aboard T-TIDE leg 3, Matthew Alford, talks about the challenges and accomplishments of a day at mooring site “A1”

Revelle: The Pulse of the Ocean

      After several days of exploring nearby sites, we’ve turned attention to a small hill on the side of the continental slope where computer simulations have suggested that large internal waves and energetic turbulence would be found. Using the computer controlled guidance system in the ship, we’ve taken a number of repeated transects across the top of this … Read More

Revelle: Breaking undersea waves make you a fish sandwich

The giant subsurface waves the T-team are studying are triggered thousands of kilometers away. After beaming through the Southern Ocean, the waves break against the continental slope, mixing the deep ocean. But, like bath-time with a hyperactive toddler and an especially slippery rubber ducky, these waves occasionally slosh up and over the edge of the tub. In the relatively shallow waters … Read More

Revelle: Digging In

We shoved off from Macquarie Wharf in Hobart on Friday afternoon. Departure is always a bit spooky on the Revelle. There’s no roaring of diesels or shuddering of massive driveshafts. The Z-drive propellers are vectored, the electric propulsion motors are energized, and the dock silently recedes. We spent some time swinging the compass (swinging the ship to calibrate the compass), & … Read More
