Effects of soot deposition on particle dynamics and microbial processes in marine surface waters

Large amounts of soot are continuously deposited on the global ocean. Even though significant concentrations of soot particles are found in marine waters, the effects of these aerosols on ocean ecosystems are currently unknown. Using a combination of...

Spatial mismatch between marine protected areas and dugongs in New Caledonia

Marine protected areas (MPAs) are a powerful tool for conserving marine biodiversity when designed using ecological information and conservation goals and targets. Dugongs (Dugong dugon) were not an explicit target in the design of the network of MPA...

Colonization and release processes of viruses and prokaryotes on artificial marine macroaggregates

Marine organic aggregates are sites of high of viral accumulation; however, still little is known about their colonization processes and interactions with their local bacterial hosts. By taking advantage of a novel approach (paramagnetic functionaliz...

Decadal increase in the number of recreational users is concentrated in no-take marine reserves

In coastal areas, demographic increase is likely to result in greater numbers of recreational users, with potential consequences on marine biodiversity. These effects may also occur within Marine Protected Areas (MPAs), which are popular with recreat...

Structure and Plate Tectonic Evolution of the Marine Arctic as Revealed by Aeromagnetics

Over 400,000 km of low level aeromagnetic data were collected by US Navy research organization over the Arctic Basin and Greenland-Norwegian Sea during the years 1972 to 1978. These data provide new constraints on the crustal structure and tectonic e...

Marine birds of d'Entrecasteaux Reefs (New Caledonia, southwestern Pacific) - Diversity, abundance, trends and threats

We present the first information on waterbirds, especially breeding marine birds, from three islands of d'Entrecasteaux Reefs (Surprise, Fabre and Huon), northern New Caledonia, south western Pacific. Using different sampling and counting techniques...
