I was glued to my computer last night both to see how the future of country would take shape but see if the Blue Belt would emerge last night. Not sure what I am referring to?

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
The largest unit of defined geologic time is the supereon. Only one is defined, the Precambrian spanning from the formation of the Earth to right before life goes crazy in the Cambrian explosion (4.6 billion years ago to 542 million years ago). Oddly, there is no other supereon after the Precambrian, just the Phanerozoic eon . . . → Read More: On the Reasons Why We Need A New Supereon
I’m a contrarian. Majority consensus makes me shudder. I just like rooting for underdogs*. Those undersea ridges at the boundaries of tectonic plates, spewing molten magma to form new crust are o’ so popular these days. Spreading plate boundaries…meh. What I do like is new research basically stating, and I am paraphrasing here, that spreading . . . → Read More: I Like Sills But Not A Fan Of The Popular Or My Friend’s Ex
Map of the Altantis Massif showing the locations of the Integrated Ocean Drilling Program Expeditions 304 and 305, Hole 1309D (yellow circle) and the Lost City Hydrothermal Field (green circle). From Mason et al. 2010 A flurry of new research is redefining our views on where life resides on Earth. The biosphere is the zone . . . → Read More: Finding Life Where the Sun Don’t Shine
A mysterious plume, possibly a stream of ice-covered methane bubbles (inset arrow), rises about 1.4 kilometers from the seafloor off the coast of California. The plume originates in a previously unknown, amphitheater-shaped scar (main image, arrow) on the ocean bottom about 32 kilometers northwest of California’s Cape Mendocino. A recent oceanographic survey on the NOAA . . . → Read More: The Creation of a New Deep-Sea Feature
A new paper published recently in the journal Geology reports on peculiar conga party lines of our paleo-friend, the Trilobite. Gutierrez-Marco and colleagues discovered a quarry replete with marine invertebrate fossil, including potentially some of the largest trilobite specimens ever found. Curiously though, these capricious little critters were found exhibiting some rather gregarious behavior! They . . . → Read More: Trilobites Ride the Crazy Train
