Ebola and “the French Disease”

Jim Moore and I were both students in the PhD Program in Anthropology at Harvard a few years ago. He graduated about the time I entered the program. To give a rough historical touchstone, I remember the day he needed to get his thesis off to the Registrar, and there was a delay because it…

Ocean Roundup: Scientists Call for “Bold” Action on Overfishing, Shipping Company Pleads Guilty to 2013 Molasses Spill, and More

Early-morning trawlers leave port in the Mediterranean. (Photo: Oceana / Juan Cuetos) - In a new article, scientists called for “bold” action on overfishing and habitat destruction around the world for both industrial and small-scale fisheries. They call for more marine protected areas, and coordinated management and government activities. Phys. org read more

Tutorial 29: how to choose a title for your paper

Over on his (excellent) Better Posters blog, Zen Faulks has been critiquing a poster on affective feedback. The full title of the poster is “Studying the effects of affective feedback in embodied tutors”. Among other points, Zen makes this one: As a browser, I often want a take home message. This isn’t helped by the weak title, […]

Here’s that wallaby-skull multiview you ordered

Variability in the skeletal mineralogy of temperate bryozoans: the relative influence of environmental and biological factors

Bryozoans exhibit a highly variable geochemistry within their calcium carbonate skeletons. Previous studies have predominantly attributed this variability to differences in seawater temperature influencing the relative deposition of aragonite and calcite, and the extent of magnesium incorporation into the calcite lattice.

The effects of pH on acoustic transmission loss in an estuary

Increasing atmospheric CO2 will cause the ocean to become more acidic with pH values predicted to be more than 0.3 units lower over the next 100 years. These lower pH values have the potential to reduce the absorption component of transmission loss associated with dissolved boron. Transmission loss effects have been well studied for deep […]

Nesonektris aldridgei Shows Cambrian Vetulicolians Were Vertebrate Cousins

A new vetulicolian from Australia and its bearing on the chordate affinities of an enigmatic Cambrian groupAuthors: García-Bellido et alAbstract:BackgroundVetulicolians are one of the most problematic and controversial Cambrian fossil groups, having been considered as arthropods, chordates, kinorhynchs, or their own phylum.

Effects of ocean acidification on the biogenic composition of the sea-surface microlayer: Results from a mesocosm study

The sea-surface microlayer (SML) is the ocean’s uppermost boundary to the atmosphere and in control of climate relevant processes like gas exchange and emission of marine primary organic aerosols (POA). The SML represents a complex surface...Show More Summary

Science chief warns on acid oceans

The UK’s chief scientist says the oceans face a serious and growing risk from man-made carbon emissions. The oceans absorb about a third of the CO2 that’s being produced by industrial society, and this is changing the chemistry of seawater. Sir Mark Walport warns that the acidity of the oceans has increased by about 25% […]

Water flow modulates the response of coral reef communities to ocean acidification

By the end of the century coral reefs likely will be affected negatively by ocean acidification (OA), but both the effects of OA on coral communities and the crossed effects of OA with other physical environmental variables are lacking. One of the least considered physical parameters is water flow, which is surprising considering its strong […]

Escape performance of temperate king scallop, Pecten maximus under ocean warming and acidification

Among bivalves, scallops are exceptional due to their capacity to escape from predators by swimming which is provided by rapid and strong claps that are produced by the phasic muscle interspersed with tonic muscle contractions. Based on the concept of oxygen and capacity-limited thermal tolerance, the following hypothesis was tested: ocean warming and acidification (OWA) […]

Ocean acidification does not impact shell growth or repair of the Antarctic brachiopod Liothyrella uva (Broderip, 1833)

Marine calcifiers are amongst the most vulnerable organisms to ocean acidification due to reduction in the availability of carbonate ions for skeletal/shell deposition. However, there are limited long-term studies on the possible impacts of increased pCO2 on these taxa. Show More Summary

La biodiversité: Sous l’océan, les espèces en danger (audio, in French)

Dernier temps de notre semaine consacrée à la biodiversité. Ce matin: Cap sur l’océan Avec nous pour en parler: Jean-Pierre Gattuso, en duplex depuis Nice, qui est directeur de recherche CNRS au laboratoire d’océanographie de Villefranche. Il a reçu la médaille Blaise Pascal 2013 de l’European Academy of Sciences (EURASC). Il a par ailleurs été […]

Acidification effects in the behavioural responses of temperate reef fish larvae

Due to anthropogenic activity, atmospheric CO2 levels have been increasing since the last century. Consequently, the average levels of surface pH in the ocean is drastically dropping, affecting marine life, including changes in fish behaviour. In many coastal marine fish the selection of the adult habitat occurs in the pelagic larval phase, relying on hearing […]

Ocean Acidification Forum and Winter Networking Event, 16 December 2014, Portland

Tuesday, Dec. 16, 2014 4:30 p.m. to 7:30 p.m. Location: Gulf of Maine Research Institute, 350 Commercial St, Portland, Maine Ocean acidification is changing the chemistry of the ocean and is caused primarily by the buildup of carbon dioxide and reductions in pH and calcium carbonate in its waters. Runoff and river discharges, as well […]

The Biggest Loser: Shark Edition

Ocean acidification could be the ultimate weight-loss plan for fish. And that’s not a good thing. Are you an overweight shark having trouble saying no to second, third, and fourth helpings? Do you stay up late at night slamming squid juice after squid juice? Are you consumed by the constant desire to find, hunt, and […]

Les océans brûlés (text & audio, in French)

Tempêtes, sécheresses, fonte des glaciers, on pense à tort que les changements climatiques ont des effets essentiellement atmosphériques, mais une catastrophe plus discrète est en cours, préviennent les experts : l’acidification des océans. Show More Summary
