1. DISCO - Drivers and Impacts of Coastal Ocean Acidification
Abstract : Ocean acidification, mainly attributed to the increasing anthropogenic CO2 in the atmosphere, is characterised by a lowering pH together with a shift in the sea water carbonate chemistry toward lower concentration of carbonate ions. On the coasts, where the environmental variability is high due to natural and human impacts, ocean acidification mainly affects the frequency, magnitude, and duration of lower pH and lower calcium carbonate saturation events.

2. Digital technologies as support for learning about the marine environment: Steps toward ocean literacy : Digital technologies and ocean literacy
Abstract : Over the last century the ocean has been negatively impacted by human activities. In order to continue benefitting from marine services and goods, and the qualities afforded to human life through the ocean, citizens need to be informed about their relationship to the ocean and their own impact on it, that is they need to be ocean literate.

3. Climate change effects on marine species across trophic levels
Abstract : Climate change and anthropogenic activities are producing a range of new selection pressures, both abiotic and biotic, on marine organisms. While there are numerous studies that have investigated the response of individual marine organisms to climate change, few studies have focused on differences in organismal responses across trophic levels.

4. Arctic Ocean benthic foraminifera preservation and Mg/Ca ratios : Implications for bottom water palaeothermometry
Abstract : Reconstructions of Arctic Ocean palaeotemperatures are needed to disentangle natural variability from anthropogenic changes and understand the role of ocean heat transport in forcing or providing feedbacks on Arctic climate change. Despite known complications with calcareous microfossil preservation in Arctic Ocean sediments, calcareous benthic foraminifera can be common in interglacial sequences. READ MORE

5. Exploring gene expression responses of marine bacteria to environmental factors
Abstract : Bacterioplankton are abundant in marine ecosystems, where they as “masters of transformation” of dissolved organic matter (DOM) are important for energy fluxes and biogeochemical cycles. However, the performance of bacteria in a changing marine environment influenced by anthropogenic activities is poorly understood. READ MORE
