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.

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 Broadcast Spawn!Tweet#call_to_action h4{padding:0px 5px;}This is a time . . . → Read More: Okeanos Explorer in the Gulf of Mexico
James Cameron’s descent to the Challenger Deep – we have adventure, intrigue, and a great story for the media. But we also have an amazing opportunity for SCIENCE! Despite a faulty hydraulics hampering sample collections, the Deepsea Challenger managed to grab half a sediment core – a cupful of muddy, watery ooze from the deepest . . . → Read More: Challenger Deep: What we can learn from a single, half core of mud
