IOCCP and JAMSTEC are pleased to announce the 4th Intercalibration Exercise for Nutrients

IOCCP and Japan Agency for Marine-Earth Science and Technology (JAMSTEC) have invited more than 80 laboratories worldwide to participate in the 2014 inter-comparison study designed to test the global comparability of nutrient measurements and to promote the use of CRM of nutrients in seawater. 

 

The oceanographic community has continued to improve comparability of nutrient data from the world's oceans in many ways, including through 3 international inter-laboratory comparison studies since 2003 and the development of nutrient reference materials (RMs). However, adequate comparability and traceability of nutrient data have not yet been achieved.

Corals in Hot Water?

Racing time to predict the fate of corals in a warming ocean

 

A time bomb is ticking in the ocean, and faster than you might think. The oceans are warming, and in the next 20 to 30 years many coral reefs around the globe will reach their temperature threshold, a tipping point at which they will likely yield to weakened immune systems, bleaching disease, and in many cases, death.

 

This race against time fuels the work of Hannah Barkley, a graduate student in the MIT/Woods Hole Oceanographic Institution (WHOI) Joint Program in Oceanography.

The oceans’ sensitive skin - Ocean acidification affects climate-relevant functions at the sea-surface microlayer

Ocean acidification might alter climate-relevant functions of the oceans’ uppermost layer, according to a study by a group of marine scientists published in the “Journal of Geophysical Research: Oceans”. In an experiment led by GEOMAR Helmholtz Centre for Ocean Research Kiel, the researchers observed a close coupling between biological processes in the seawater and the chemistry of the sea surface microlayer. Also, they noted a growing number of specialised bacterial and algal cells in this microenvironment. These changes might influence interactions between the ocean and the atmosphere such as the air-sea gas exchange and the emission of sea-spray aerosols that can scatter solar radiation or contribute to the formation of clouds.

"FloatMonkey" sea trials - paving the way towards multi-disciplinary research

In continuing to develop SAEON’s capacity for offshore benthic research, the team at Egagasini have been working to expand the capabilities of the already successful SkiMonkey III camera system. Team members have added some equipment and done some alterations to make the camera system more versatile in terms of the types of data it can collect and the habitats it can access. Most significantly, the camera system now boasts an onboard MicroCAT CTD instrument (Conductivity, Temperature, Depth) made possible by funds from a National Research Foundation (NRF) Strategic Research Infrastructure Grant.

 

This additional component records physical measurements of near-bottom/seafloor water, while the camera records images of the living organisms. This will pave the way for increasingly multi-disciplinary research, with stronger links between offshore oceanography and benthic ecology.

Senior Research Scientist Ramunas Stepanauskas feted in two countries for scientific contributions

Bigelow Laboratory for Ocean Sciences Senior Research Scientist Ramunas Stepanauskas was in the enviable position of being asked to be in two different countries to accept two separate awards recognizing his significant contributions to science at the same time. Stepanauskas opted to travel to his native Lithuania to accept the Lithuanian Ministry of Science and Education award for achievements in science. The award was presented in Vilnius, Lithuania on November 4.
