Dr Jason Hall-Spencer at the Guardian

Dr Jason Hall-Spencer has written an excellent essay on the urgency of oceanic action, fueled by the recent findings of the International Programme on the State of the Ocean (IPSO).  Make sure to check it out.

The crux of the problem is that the rate of changes in ocean systems is accelerating and outstripping what was expected just a few years ago. Destructive fishing practices, pollution, biodiversity loss, spreading low-oxygen “dead zones” and ocean acidification are having synergistic effects across the board – from coastal areas to the open ocean, from the tropics to the poles.

On the precipice

Gorgonian and dive-Doug Anderson on Flickr-CCatttr-non$

Over the next few weeks, I am/will continue to be feverishly running analyses and writing up my Masters.  So Uncharted Atolls will be on a temporary hiatus.

In the meantime, be sure to check out some of my favorite recent-ish articles in the ‘Suggested Reading’ list over there on the right. Also, here’s a short list of some excellent (if I do say so myself) sciency reading suggestions that I occasionally still find time to enjoy:

Deep-Sea News

Not Exactly Rocket Science

I’m a Chordata!  Urochordata!

Southern Fried Science

Wired‘s network of science blogs

Sea Monster

Culturing Science

If you like podcasts, RadioLab is wonderful.  And don’t forget the links in the sidebar (again, to the right)!

On my bedside table, there’s Darwin’s Armada:  Four Voyages and the Battle for the Theory of Evolution by Iain McCalman, occasionally interspersed with Stephen Pinker’s The Stuff of Thought, generously gifted by the Southern Fried Science trio (hurray for filling out surveys!).

I can be found occasionally on Twitter.

Ove Hoegh-Guldberg speaks on climate change in the ocean

From the 2011 National Council for Science and the Environment conference in Washington, D.C.  You can find out more about Dr Hoegh-Guldberg at his laboratory site.

Debris patch from Japan’s tsunami en route to US

As if the tragic loss of life and ongoing nuclear woes weren’t enough, researchers Nikolai Maximenko and Jan Hafner at the International Pacific Research Center, University of Hawaii, predict that the massive deluge of debris that last month’s tsunami washed into the  sea is headed across the Pacific.  Using data from drifting oceanic buoys, the model predicts the debris will first spread out within the North Pacific Subtropical Gyre and start washing up in the Papahanaumokuakea Marine National Monument (NW Hawaiian islands) in a year.  In three years, the rest of the Hawaiian islands, the US West Coast, British Columbia, Alaska, and Baja California will see effects on their shorelines.  After the journey, the researchers predict that the debris will enter the North Pacific Garbage Patch and eventually get broken done into smaller particles.  In five years, Hawaii is expected to see another, more severe plume of oceanic trash.  Hopefully, these projections will help to inform clean-up responses.  The oceanic trash that does not either wash up on shorelines or sink, can end up in marine organisms.

Stomatopod SMASH!: biomechanics of an invertebrate’s weaponry

This is the mighty stomatopod, the last thing some unlucky sea creatures ever see.  The energy for the stomatopod’s strike comes from a spring-type mechanism, which helps to explain the incredible speed of the attack.  In the below video from the Dunn Lab’s CreatureCast, Nati Chen takes us through the motions of this swift invertebrate.

Be sure to also check out this TED talk from Sheila Patek, who studies animal speed, including stomatopods’.  Before being usurped by another arthopod, Dr Patek showed that a species of stomatopod held the title of fastest feeding strike of any animal.

The deep sea of the Coral Triangle

Last year, Dr. Tim Shank led an expedition into the deep sea of the Coral Triangle, finding dozens of new species. The diversity of species the team is describing may be evidence for a deep-sea Wallace line. Read more at the Economist.

Teaching sharks that lionfish are tasty?

Some gutsy local divers have been teaching sharks just how good lionfish are to eat in Roatan Marine Park off the coast of Honduras [The Seamonster].

Dr John Bruno, over at the excellent new ocean-science blog, Seamonster, points out some new efforts in the fight against a particularly troubling invasive species, the lionfish.  Lionfish are native to the Indo-Pacific but have invaded waters along the US eastern seaboard, all the way down to South America, and represent an enormous ecological change, as pretty much nothing is left to eat them.  But apparently there are efforts afoot to change that, by working with sharks, and by attempting to convince a largely land-based bunch of bipeds that they’re yummy as well.
