There are scientists floating in the middle of the North Atlantic who are holding the dinosaur extinction in their hands. Really. Here it is: This may look like an alien landscape, but it’s actually a section of deep sea mud from the drilling ship Joides Resolution. When the lighter-toned sediment on the left was deposited, . . . → Read More: Drilling for dinosaur death: the Joides Resolution finds extinction in deep sea mud
Bathyscaphe Trieste I asked, “What were the events that lead to you to dive the Marianas Trench?” Don Walsh one of two men to first visit the deepest point of the world’s ocean and one of only three to succeed at this responded quickly. “I found myself there for all the wrong reasons.” Don Walsh . . . → Read More: I Am Science with the First Man to Dive Challenger Deep
This week the NOAA ship Okeanos Explorer has been dropping its ROV Little Hercules onto various features in the northern Gulf of Mexico, including an old wood/iron wreck, salt domes and man-made seismic trenches. Okeanos has an interesting remote arrangement where folks back on the continent can direct the ROV pilots in real time by . . . → Read More: TGIF – Pretty pictures from Okeanos Explorer
Act 1: Wood Falling on Water At two miles below the ocean’s surface, I see wooden carcasses, once buoyant, lying listlessly on the abyssal seafloor. They range from small fragments to 2000+ pound behemoths. Ligneous cadavers litter the seafloor, a last resting place for visitors from a faraway and drier place, becoming rare as . . . → Read More: A Lonely Tree Far From Home Brings New Life to the Ocean Deep: A Narrative in Five Acts
This is an invited contribution. A marine biologist, who posts here under the pseudonym, Dour Marine Biologist, offers a counter to the media and even DSN hype on Cameron’s dive. I find these points below worth consideration and dialogue. I want to hear your comments below. Since James Cameron’s record-breaking dive on March 26th the . . . → Read More: Shouldn’t We Be More Skeptical of the DeepChallenger Dive?
This is a time sensitive post. By the time some find it, there may be nothing showing, but right now at 1155hrs EDSL, there’s a great feed from the Little Hercules ROV at the bottom of the Gulf of Mexico, looking at some deep corals See more here . . . → Read More: Okeanos Explorer in the Gulf of Mexico
Edit – In the original article I said that the sphere of the Deep Challenger was made of titanium. In fact, it’s made of steel. My bad! In trying to explain to friends, colleagues and Twitter followers during recent days what James Cameron may have seen out that softball-sized window of the Deep Challenger submersible . . . → Read More: Cool as a sea cucumber: life (and death) at extraordinary deep sea pressures

This post is co-authored by Al Dove and Craig McClain In the 1989 James Cameron sci-fi movie The Abyss, there’s a scene when Ed Harris’ character dons a special environmental suit that allows him to breathe an oxygen-laden liquid. Thus protected from the risks of crushing deep-sea pressures (no air = no voids to collapse), . . . → Read More: James Cameron’s Deep Sea Challenge: a scientific milestone or rich guy’s junket?
