Bruno Lemoine, who runs the cellars of Chateau Larrivet Haut-Brion in the southwest Bordeaux region, asked his barrel-maker chum Pierre-Guillaume Chiberry to build him two small 56-litre wooden barrels in which to age his red wine by an extra six months.

One was to be kept in the chateau cellars, the other sunk underwater among the prized oyster beds of the Bay of Arcachon, north of Bordeaux on the Atlantic coast.

The barrel kept at the chateau was dubbed "Tellus", after the Roman goddess of the land, and the other "Neptune" after the sea god.

Scientists identified two distinct populations of white shark at the east and west of Bass Strait in Australian waters, prompting researchers to suggest the huge fish may need a regional conservation plan.

The study examined tissue samples from 97 sharks collected around Australia since 1989 which were caught in beach safety programs, as fishery bycatch and during Commonwealth Scientific and Industrial Research Organisation (CSIRO) field research. Its findings are broadly consistent with satellite and acoustic tracking research led by CSIRO’s Barry Bruce.

The study also predict, based on projections from multiple models, that egg and hatchling survival will drop by half in the next 100 years as a result of global climate change.

When leatherback turtle hatchlings dig out of their nests buried in the sandy Playa Grande beach in northwest Costa Rica, they enter a world filled with dangers. This critically endangered species faces threats that include egg poaching and human fishing practices.

Scientists at the Max Planck Institute for Marine Microbiology from Bremen together with their colleagues from Australia, Sultanate of Oman and Italy have investigated how and why the corals die when exposed to sedimentation. According to their findings, oxygen depletion, together with an acidification of the environment, creates a chain reaction that leads to coral death.

A few bottles of beer were found in an old shipwreck in the archipelago of Åland in Finland during the summer of 2010. Researchers have now managed to isolate four different species of live lactic acid bacteria from the beer.

The 2010 discovery of the ship, believed to have sunk in the 1840s, also included the world's oldest champagne considered drinkable which has since been auctioned off.

Beaked whale species are thought to be sensitive to noise arising from certain human activities; in 2000, beaked whale strandings were observed coinciding with naval sonar exercises in the Bahamas.

Understanding the distribution and behavior of these species is important to minimize harmful impacts from human uses of the ocean.

A research team from Duke University, Woods Hole, and the Naval Undersea Warfare Center listened for foraging beaked whales and measured ocean features and distributions of prey off the eastern coast of Andross Island in the Bahamas.

Pelvicachromis taeniatus is a dwarf cichlid from West Africa that is occasionally kept as an aquarium fish In this species, females seek to impress potential mates as well by fanning out their large, violet pelvic fin.

 

The results, published this month in BMC Evolutionary Biology, also suggest male choice can drive females to evolve exaggerated traits, a finding that disputes the traditional belief that sexual selection is a one-way road, allowing only females to affect male appearance.

 

In a study published in BMC Public Health, an open access journal, tilapia was introduced into abandoned fish ponds at an altitude of 1,880m and the effect measured over six months on the numbers of mosquito immatures.
