On the Reasons Why We Need A New Supereon
by Dr. M in Deep Sea News
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 . . . → Read More: On the Reasons Why We Need A New Supereon... Read more »

A Blanket of Mucus
by Dr. M in Deep Sea News
You are fish. The guy above is your enemy, a Gnathiid isopod, a vicious parasitic relative of a roly-poly. Your defense? You cough up enough loogies to coat yourself in a protective layer of joyous mucus.
Of course you are not a fish and fish don’t need to cough 1,000′s of thick loogies. If you were a parrotfish . . . → Read More: A Blanket of Mucus... Read more »

Tide Pool: Cephalopods, Ash, and Sulphur Are to Blame
by Dr. M in Deep Sea News
An occasional series where we briefly report 3 new studies and tell you why they are cool!
Heightened biodiversity may make an ecosystem more stabile and robust. One of the reasons for this is that high biodiversity may create redundant species, i.e. species that serve a similar ecological role in the ecosystem.

Deep-Sea Creatures Play in the Same Band
by Dr. M in Deep Sea News
I am really loving the new paper by O’Hara et al. The gist is we typically think of the different oceans having unique sets of deep-sea organisms. A Pacific set of animals, an Atlantic set, an Indian set and so on. But O’Hara and colleagues show instead that brittle stars are differentiated along broad latitudinal bands. This is very similar to . . . → Read More: Deep-Sea Creatures Play in the Same Band... Read more »

Scientist In Residence: Danny Richter on Diatoms and X-ray Whosamagidgets

In a recent paper, de Jonge et al used x-ray fluorescence tomography to give us a new perspective on how diatoms put together those phenomenally intricate frustules of theirs. “X-ray whosamagidget” you say?

Can Sea Snakes Predict The Future? What About Hurricanes? Lottery Numbers?
by Dr. M in Deep Sea News
Undoubtedly you have heard that dogs can sense earthquakes before the tremors occur. While anecdotes are common, experimental evidence supporting these claims remains elusive. The USGS in the 1970′s even examined the ability of animal prediction “but nothing concrete came out of [these experiments]“.

Ocean acidification is evil: a not-so-great poem
by Dr. M in Deep Sea News
Ocean acidification is evil.
Ocean species expect great upheaval.
Horrific for survival, expect no survival
Second worst for calcification, what an abomination!
Dire but better for growing with all signs of slowing.
Photosynthesis and reproduction fair the best, but unpleasant like all the rest.
If you’re a calcifying organism, kiss you sweet hardened ass goodbye.
Because it’s marked with a giant bull’s eye.
