The impact of CO2 emissions on ‘nuisance’ marine species (video & text)

Anthropogenic CO2 emissions are being taken up from the atmosphere by the oceans, increasing the availability of dissolved inorganic carbon but reducing both the carbonate saturation and pH of seawater. This ocean acidification affects biological processes in a wide range of marine taxa. Here, we assess the likely responses of ‘nuisance’ species to ocean acidification, […]

Natural variability in the surface ocean carbonate ion concentration (update)

We investigate variability in the surface ocean carbonate ion concentration ([CO32?]) on the basis of a~long control simulation with an Earth System Model. The simulation is run with a prescribed, pre-industrial atmospheric CO2 concentration...Show More Summary

First Tide Table Publication

  In December 1866, the U.S. Coast Survey (NOAA’s predecessor agency) began printing tide tables as an independent, annual publication. The first edition, for the year 1867, separated the predictions for the Atlantic coast and Pacific coast of the United States into two publications and gave only the daily high tides. Low tides were added […]

Baby Giant Squids

We know almost nothing about Giant Squids with mantles lengths less than 1000 mm  (~40 inches).  Very young squids are even more enigmatic than adults.  A recent study reports the collection of three very young Giant Squids off the Japanese coast.  The three young measured 140.8, 332, and 332 mm (5.5 and 13 inches). The heaviest of […]

A weird but wonderful fish

A Monkeyface-eel in our Rocky Shore gallery. Fans of unconventional beauty will appreciate the Monkeyface-eel (Cebidichthys violaceus). Aside from its unusual appearance, this fish (yep, it’s a fish) is completely normal. Just kidding! This guy can breathe air and survive out of the water. Show More Summary

Climate change is having a big impact on the health of the ocean and ocean wildlife. We can all make a difference! Let your representatives know that this important issue requires urgent action. This is about all of us. ?#?EarthToPa...

4th International Symposium on the Ocean in a High-CO2 World: new deadline for abstract submission – 11 November 2015

Abstracts for the 4th International Symposium on the Ocean in a High-CO2 World were due to be submitted by 4 November. We have received a number of requests for extensions. As such, we will accept abstracts until midnight on Wednesday 11 November (Australian Eastern Daylight Time, AEDT). Submission can be made via the online presentation […]

2016 Mares Conference: Abstract submission reopened for researchers from developing countries working on ocean acidification

New deadline for abstract submission: 19 November 2015! The MARES Consortium, EuroMarine Network and International Atomic Energy Agency Ocean Acidification International Coordination Centre (IAEA OA-ICC) are pleased to announce that the abstract submissions have reopened for researchers from developing countries working on ocean acidification.

Quantifying preferences and responsiveness of marine zooplankton to changing environmental conditions using microfluidics

Global environmental change significantly affects marine species composition. However, analyzing the impact of these changes on marine zooplankton communities was so far mostly limited to assessing lethal doses through mortality assays and hence did not allow a direct assessment of the preferred conditions, or preferendum.

Making plans for Veterans Day? We’re celebrating the bravery and sacrifice of U.S. military personnel by offering free admission on Veterans Day for veterans, active-duty military, reservists and retirees, with valid military ID.  Discount tickets for family members can be purchased in advance at many California and Nevada bases.

Variability in carbon availability and eelgrass (Zostera marina) biometrics along an estuarine gradient in Willapa Bay, WA, USA

Because photosynthesis requires CO2, carbon limitation in aquatic environments could restrict primary production and provide signals in tissue chemistry. We took advantage of spatial variability of aqueous [CO2] in estuaries to examine within-estuary variation in biometrics of intertidal eelgrass (Zostera marina) during peak summer production.

How long would it take to drain the ocean?

We are honored to have a guest post from David Aldridge (@D_Aldridge on Twitter) a marine biologist and Pd.D. survivor. He is founder of @Words_in_mOcean.  Please check out his new book Do Fish Sleep? What if somebody removed a bathroom plug from the bottom of the ocean… how long would it take all the water in the […]

Abrupt changes in food chains predicted as Southern Ocean acidifies fast: study (text & video)

  The Southern Ocean is acidifying at such a rate because of rising carbon dioxide emissions that large regions may be inhospitable for key organisms in the food chain to survive as soon as 2030, new US research has found. Tiny pteropods, snail-like creatures that play an important role in the food web, will lose their […]

IDDRI Policy Brief “Intertwined ocean and climate: implications for international climate negotiations” now available in French, Spanish and Chinese

  This policy brief is the result of the “Oceans 2015 Initiative”, an expert group supported by the Prince Albert II of Monaco Foundation, the Ocean Acidification International Coordination Centre of the International Atomic Energy Agency, the BNP Paribas Foundation and the Monégasque Association for Ocean Acidification. It has been produced under the leadership of […]

I Pity the Species That Doesn’t Decorate

Mr. T made mohawks and fool pitying a life goal for many.   Another life goal for many, thanks to first name Mr, middle name period, last name T, was decorating themselves with enough gold chains to crash a third-world economy.   Although humans are the only species where decoration functions strongly in social interactions (see Beyonce), […]

Plunging pelicans

Pouch pounce A pelican’s bill can hold three times more than its stomach can—nearly three gallons of fish and water! At the end of a successful dive, the pelican drains the water from its pouch and swallows the whole fish head first—turning it if necessary. Show More Summary

How Urban Renewal Gets You Giant Sea Hares

Why masses of giant ocean mollusks invading your city’s rest & relaxation zone is actually a good thing   At the heart of downtown Oakland, San Francisco’s stereotypically grittier and unpolished sister city across the San Francisco Bay, lies an urban lake that is experiencing a remarkable rebirth. Lake Merritt isn’t so much a lake […]

Abrupt onset and prolongation of aragonite undersaturation events in the Southern Ocean

Ocean acidification may lead to seasonal aragonite undersaturation in surface waters of the Southern Ocean as early as 2030 (ref. 1). These conditions are harmful to key organisms such as pteropods2, which contribute significantly to the pelagic foodweb and carbon export fluxes in this region3. Although the severity of ocean acidification impacts is mainly determined […]
