Oceanographic vessels from Greece, Italy, Spain, France, Romania, Russia, Turkey, Bulgaria and Israel will simultaneously sample the Mediterranean and the Black Sea this summer, in order to collect data for the SESAME database.
This set of cruises will trace the same sea routes as the Ünlüata cruises of March-April 2008, in order to study and compare the two seas at different times of the year and thus assess the seasonal variability of the ecosystems.
The main objective of the SESAME Autumn Cruises is to sample the two environments at the same time, and thus prepare high quality datasets of new hydrographical, chemical and biological data collected. Some of the parameters to be measured include temperature, salinity, dissolved oxygen, nutrients and chlorophyll-a. Additionally, samples for inorganic and organic dissolved carbon measurements, total alkalinity, as well as bacterial, phytoplankton and zooplankton biomass and production will also be taken. Finally samples of the CO2 concentrations in the sea water and the air will be measured to identify the role of the sea in terms of carbon sequestration. All these will be incorporated into the SESAME database and will be used for the implementation, tuning and evaluation of the ecological models.
The innovation of the project is that for the first time in March-April 2008 the two seas were sampled simultaneously; these new cruises will add more data to the project’s database especially for the summer season and thus help produce a clear and accurate snapshot of the state of the two ecosystems to help reproduce the model outputs as accurate as possible. All sampling activities fall under the project’s work frame, and this newly collected data will be compared to historical data sets from 50 years ago. The results will, in turn, feed the models which will produce scenarios to predict possible changes in these ecosystems in the next 50 years to come.
Scientists, journalists, the general public, and schools in particular are invited to ‘follow’ the cruises online, as a special map with all stations, a cruise diary, and photos from aboard the research vessels will be uploaded daily on the website. A special area to host the cruises online has been created, where each vessel is shown with clear location coordinates, and also includes photos, as well as the daily diary both in the respective language and in English, thus making it accessible to a wide audience. Additionally, some schools will be able to connect to the researchers via a telephone connection, thus further strengthening the education initiatives and public outreach that underpin the project.
These cruises will not only collect crucial data for these ecosystems, but they add a societal and educational perspective to science, which will encourage the involvement of school children, and the society at large, in research activities, with the hope of raising awareness about the sea and climate change in general.

Species Richness – a false friend? Scientists want to improve biodiversity assessments

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
