A l'occasion d'une réunion du Conseil de sécurité sur la piraterie au large de la Somalie, le Secrétaire général adjoint aux affaires politiques, Jeffrey FELTMAN, a souligné mercredi les progrès réalisés contre ce fléau mais a jugé qu'il fallait aider la Somalie à développer ses institutions pour s'assurer que ces progrès perdurent.

La directrice scientifique adjointe de l'IFREMER, Clara Ulrich, a reçu mardi 8 septembre 2020 le prestigieux Outstanding Achievement Award du CIEM (Conseil international pour l'exploration de la mer). Un prix qui récompense son travail sur les pêcheries mixtes (capture de plusieurs espèces) dans le cadre de la Politique Commune de la Pêche.

Pirates shift tactics to target crews, not cargo.

Énergie renouvelable : Maurice veut construire des parcs éoliens en mer.

15th May - Earlier today, following the decision taken on 23 March 2012 by the Council of the European Union to allow the EU Naval Force to take disruption action against known pirate supplies on the shore, EU forces conducted an operation to destroy pirate equipment on the Somali coastline.

Opponents claim the plan to bait and kill sharks breaches state and federal laws, and international agreements

While noting the progress made to combat piracy off the coast of Somalia, the United Nations political chief today said that a sustained long-term solution must include the presence of effective Government and State institutions that provide basic services and alternative ways for people to make a living.

The western Indian continental shelf houses the world's largest naturally formed coastal low-oxygen zone that develops seasonally during the summer monsoon. We investigated multiple reductive nitrogen transformation pathways and quantified their rates in this system through anaerobic incubations with additions of 15N-labeled substrates during the anoxic period for three consecutive years (2008-2010). Addition of 15N labeled ammonium (15NH4+) resulted in low to moderate anaerobic ammonia oxidation (Anammox) rates in about half of our incubations from the oxygen depleted waters. In contrast, incubations with labeled nitrite (15NO2-) led to large production of 30N2 over 29N2 in all incubation experiments, indicating denitrification to be the dominant N-loss pathway. Rates of dissimilatory nitrate/nitrite reduction to ammonium (DNRA) were found to be highly variable and were lower by an order of magnitude than the denitrification rates. Extrapolation of average rates over the sampling periods and volume of anoxic waters showed large nitrogen removal (3.70-11.1 Tg year-1) which is about three times as high as the previously reported estimate (1.3-3.8 Tg year-1). Despite the small area it occupies, this shallow seasonal anoxic zone may account for as much as 20-60% the of the total annual fixed nitrogen loss in the perennial oxygen minimum zone of the Arabian Sea.

The deep sea is the largest environment on Earth, comprising important resources of commercial interest. It is composed of a wide variety of ecosystems, which is home to often unique organisms that are yet to be described. The deep-sea is one of the least studied environments, where research is strongly linked to technological access and advances. With the recent advances in the next-generation sequencing and bioinformatics tools, there is an enhanced understanding of microbial diversity and ecological functions in deep sea. Multidisciplinary programs are being undertaken to investigate into microbial communities in diverse marine environments. As compared to other Oceans, the deeper parts of Indian Ocean are still poorly sampled and studied for bacterial, and more so fungal diversity. The studies reporting usage of modern sequencing tools to describe uncultured microbial diversity have seen a rise in numbers in the last decade. In this review, we summarize the important findings of research works carried on bacterial and fungal diversity from the abyssal regions of the Indian Ocean and provide our views on possible future paths.

The genus Scomberomorus, with 18 nominal species, sustains a significant heterogeneous fishery throughout its range. The sole molecular systematic study of this genus concerned the species group S. regalis, which contains the new world taxa. The species diversity of Scomberomorus in the northern Indian Ocean has not been studied at the molecular level, often leading to misidentifications...
