Clownfish spend their entire lives nestling in the protective tentacles of host anemones, but new research shows that as babies they sometimes travel hundreds of kilometres across the open ocean. Although the process of long-distance dispersal by reef fish has been predicted, this is the first time that the high level exchange of offspring between distant populations has been observed.

Dr Steve Simpson, Senior Lecturer in Marine Biology and Global Change in Biosciences at the University of Exeter, and colleagues from the Australian Research Council Centre of Excellence for Coral Reef Studies (ARC COE CRS), Sultan Qaboos University (Oman) and the Centre National de la Recherche Scientifique (France) have published their findings on the dispersal of Omani clownfish larvae in the journal PLOS ONE.

Helfer für Schneeleoparden-Schutzprojekt gesucht

Verschneite Berggipfel, wilde und seltene Tiere, Eintauchen in eine ganz andere Kultur – so manch einen ergreift das Fernweh, wenn er an das nördliche Tian-Shan-Gebirge in Kirgistan denkt. Doch die Region benötigt vor allem Hilfe, um eine der am stärksten gefährdeten Großkatzen der Welt zu schützen: den Schneeleoparden. Daher hat der NABU Kirgistan eine Kooperation mit der Naturschutzorganisation Biosphere Expeditions gestartet.

„Biosphere Expeditions ermöglicht es Laien, an echten Naturschutz-Mitforscherreisen teilzunehmen.“, erklärt Dr. Matthias Hammer, Gründer und Chef von Biosphere Expeditions. „Das lokale Wissen des NABU Kirgistan und unser Know-how im Bereich des sanften Öko- und Wissenschaftstourismus bilden dabei die Grundlage für die Expedition.“ (more…)

„Die große Chance, die Arktis zu schützen, bevor sie zerstört wird“

Wie wirkt sich die Versauerung der Ozeane in 20, 40 oder gar 100 Jahren aus? Heute hat das GEOMAR Helmholtz-Zentrum für Ozeanforschung Kiel die Ergebnisse eines Experiments aus dem Jahr 2010 veröffentlicht – das Greenpeace mit einer Schiffstour in die Arktis unterstützt hat. Iris Menn, Meeresbiologin, erinnert sich im Interview an die Expedition.

Der zunehmende Ausstoß von Treibhausgasen macht nicht nur dem Klima zu schaffen. Unsere Meere nehmen CO2 aus der Atmosphäre auf, das sich im Wasser zu Kohlensäure wandelt. Steigender CO2-Ausstoß lässt auch die Aufnahme in das Meer steigen – das Wasser wird sauer. (more…)

NASA/WHOI Voyage Set to Explore Link Between Sea Saltiness and Climate

A NASA-sponsored expedition is set to sail to the North Atlantic’s saltiest spot to get a detailed, 3-D picture of how salt content fluctuates in the ocean’s upper layers and how these variations are related to shifts in rainfall patterns around the planet.

The research voyage is part of a multi-year mission, dubbed the Salinity Processes in the Upper Ocean Regional Study (SPURS), which will deploy multiple instruments in different regions of the ocean. The new data also will help calibrate the salinity measurements NASA’s Aquarius instrument has been collecting from space since August 2011. (more…)

A Prime Seat to a Once-in-a-Lifetime Spectacle

Hosted by world-renowned astrophotographer Adam Block at the UA’s Mount Lemmon SkyCenter, a group of sky and astronomy enthusiasts watched Venus cross the sun from the highest vantage point in Southern Arizona.

On Nov. 24, 1639, in the tiny village of Much Hoole not far from Liverpool, England, a poor farmer’s son and self-taught astronomer affixed a sheet of paper in front of a makeshift telescope pointed at the sun and waited.

Thirty-five minutes before sunset, a dark, round spot appeared right next to the bright disc that was the sun’s face projected on the paper, and made Jeremiah Horrocks, only 20 years old at the time, the first known human to predict, observe and record a transit – the passage of a planet across the sun as seen from Earth.

Almost 373 years later, a group of sky enthusiasts is gathered beneath the dome of one of the University of Arizona’s observatories on Mount Lemmon just north of Tucson, Ariz. (more…)

Scientists Look to Microbes to Unlock Earth’s Deep Secrets

*To find answers, oceanographers install observatories beneath remote seafloor*

Of all the habitable parts of our planet, one ecosystem still remains largely unexplored and unknown to science: the igneous ocean crust.

This rocky realm of hard volcanic lava exists beneath ocean sediments that lie at the bottom of much of the world’s oceans.

While scientists have estimated that microbes living in deep ocean sediments may represent as much as one-third of Earth’s total biomass, the habitable portion of the rocky ocean crust may be 10 times as great. (more…)

Dr. Livingstone’s Lost 1871 ‘Massacre’ Diary Recovered; Discovery Rewrites History

In Africa 140 years ago, David Livingstone, the Victorian explorer, met Henry M. Stanley of the New York Herald and gave him a harrowing account of a massacre he witnessed, in which slave traders slaughtered 400 innocent people. Stanley’s press reports prompted the British government to close the East African slave trade, secured Livingstone’s place in history and launched Stanley’s own career as an imperialist in Africa.

Today, an international team of scholars and scientists led by Dr. Adrian Wisnicki of Indiana University of Pennsylvania, publishes the results of an 18-month project to recover Livingstone’s original account of the massacre. The story, found in a diary that was illegible until it was restored with advanced digital imaging, offers a unique insight into Livingstone’s mind during the greatest crisis of his last expedition, on which he would die in 1873.

When a group of five high school students embarked on Project Shiphunt, an expedition in search of lost shipwrecks, in May in Lake Huron, the Woods Hole Oceanographic Institution’s Advanced Imaging and Visualization Lab (AIVL) was there, surveying and capturing 3D footage of the finds. The work was conducted as part of Project Shiphunt, an initiative developed by Sony and Intel Corp and led by National Oceanic and Atmospheric Association (NOAA).

“It was gratifying to be a part of a project that engages kids in the excitement of exploration and discovery,” said Bill Lange, director of AIVL. Lange led a crew of videographers, divers and pilots of two remotely operated vehicles (ROV) during the expedition. “Our Sony cameras gave the students the ability to have that experience in real time and in some cases to direct the cameras to investigate specific features of the wreck. The high-definition footage we collected will be invaluable to scientists and marine archaeologists working to learn from the wrecks.” (more…)
