Small algae with great potential

Unique laboratory experiment shows rapid evolutionary adaptation to ocean acidification and warming


The single most important calcifying algae of the world’s oceans is able to simultaneously adapt to rising water temperatures and ocean acidification through evolution. A unique long-term experiment with the species Emiliania huxleyi at GEOMAR Helmholtz Centre for Ocean Research Kiel shows that the evolutionary potential of the algae is much greater than previously thought. In their laboratory evolution experiment, the scientists have shown for the first time that evolutionary adaptations to multiple stress factors do not necessarily interfere with each other. Further work will reveal how evolution in ocean microbes may affect the function of the ocean in removing carbon dioxide to the deep sea and whether or not laboratory findings can be translated into the natural ocean environment.

New atlas of Southern Ocean marine life

A new atlas, providing the most thorough audit of marine life in the Southern Ocean, is published this week by the Scientific Committee on Antarctic Research (SCAR). Leading marine biologists and oceanographers from all over the world spent the last four years compiling everything they know about ocean species from microbes to whales.
It’s the first time that such an effort has been undertaken since 1969 when the American Society of Geography published its Antarctic Map Folio Series.

Royal honour for SAMS president

The president of SAMS, the Scottish Association for Marine Science, has been awarded a royal medal for his lifetime’s work developing and promoting glaciology.

 

Glaciologist Professor Geoffrey Boulton received The Royal Geographical Society’s prestigious Founder’s Gold Medal at this year’s recent annual presentation. Approved by the queen, the Society’s royal medals are among the highest awards of their kind in the world, and are presented annually in recognition of excellence and outstanding achievements in geographical research and fieldwork, teaching and public engagement.

International Ocean Sampling Day in Kiel

Researchers at GEOMAR and Kiel University participate in a global measurement campaign

 

Saturday, 21 June, is "Ocean Sampling Day." Marine scientists will take water samples at over 170 locations worldwide to investigate the distribution and genetic diversity of microorganisms in the water. Also scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel, Kiel University and the joint Cluster of Excellence "The Future Ocean" will participate in this measurement campaign, the largest of its kind. The activities can be followed live on the internet.

New Sensor Array to Monitor Impacts of Changing Gulf of Maine Conditions on New England Red Tide

Scientists from the Woods Hole Oceanographic Institution (WHOI) are kicking off an innovative NOAA-funded pilot program using robotic instruments and computer modeling analysis to shed light on changing ocean conditions in the Gulf of Maine as they relate to the harmful algal bloom (HAB) phenomenon commonly known as the New England red tide.
