Groupama et ses cinq concurrents se bagarrent avec un Indien compliqué : un creux barométrique leur barre le chemin. « Les routages s'affolent, » écrit ce matin Yann RIOU, l'équipier média.

Le sixième concurrent de la Volvo Ocean Race a annoncé hier qu'il allait boucler à la voile la première partie de l'étape 2. Team Sanya avait cassé un hauban dans l'océan Indien et est en escale technique à Madagascar.

Et les concurrents peuvent respirer. Ils ont chargé leurs bateaux hier, juste après la ligne d'arrivée du port secrEt, sur le cargo qui transportera la flotte jusqu'au nord des Émirats. Récit d'une opération tendue.

(Après 10 jours de course, Groupama sailing team a pris la tête de cette deuxième étape. Une progression dûe à une stratégie éclairée au sud du front, et à un décalage avantageux à l'est de la flotte.

Les jours se ressemblent peut-être à bord de Groupama 4, mais les Français continuent de mener la course et « les classements apportent leur lot de sourires à chaque fois, » nous écrit ce matin Yann RIOU.

Pas de jour férié pour les cinq Volvo Open 70 qui progressent vers l'arrivée de la première partie de l'étape entre Le Cap et Abu Dhabi. La flotte est menée par CAMPER, mais le bateau rouge gardera-t-il la tête jusqu'au bout ?

In recent years, enormous socioeconomic damage has been wreaked by recurrent abnormal weather events around the world. The seedbed for this abnormal weather is climate variability events on a massive spatiotemporal scale - those that cover thousands of kilometers and continue over months and years. Here we will review an article featured on the cover of the November 28, 2013 issue of Nature Geoscience on research predicting how a climate variability event in the tropical Indian Ocean, known as the Indian Ocean Dipole (IOD), will change with global warming in the future.

Le Représentant permanent de la République de Maurice aux Nations Unies, Milan Jaya NYAMRAJSINGH, a affirmé mardi à la tribune de l'Assemblée générale que le programme de développement pour l'après-2015 doit établir comme priorités le respect des droits de l'homme, l'égalité et le développement durable.

Decadal climate variability in the southern Indian Ocean could be predicted up to 10 years ahead, according to a study led by Dr. MORIOKA at Application Laboratory, the Japan Agency for Marine-Earth Science and Technology (JAMSTEC: ASAHIKO Taira, President) and his colleagues. To investigate the predictability, the scientists have used sea surface temperature (SST) observation data during 1982 to 2015 to initialize a state-of-the-art coupled general circulation model, the Scale Interaction Experiment Frontier Research Center 2 for Global Change (SINTEX-F2*) with a simple SST-nudging scheme. Their decadal reforecast experiments demonstrated moderately high prediction skills of yearly mean SST in the southwest Indian Ocean at 10-year lead time.

The extreme Western Australia 2011 marine heatwave had a lasting effect on the marine ecosystem and after 7 years, only parts of the ecosystem have showed good signs of recovery. After the heatwave, scallop fisheries in the Abrolhos Is. and Shark Bay were closed for 3-5 years, while the Shark Bay crab fishery was closed for 18 months; these fisheries at the center of the heatwave have shown some improvement due to better protection of spawning stock and improved environmental conditions. Also at the center of the heatwave, Roe's abalone suffered a catastrophic mortality and has not recovered as spawning stock remains very low. The Perth abalone stock which was outside the peak heatwave area had a major stock reduction but remained opened with reduced catches. The heatwave had a marked indirect effect on brown tiger prawns in Exmouth Gulf due to loss of seagrass habitat. The heatwave also resulted in a decline in western king prawn recruitment in Exmouth Gulf, to the north of heatwave center, but an improved recruitment in the cooler waters of Shark Bay. Western rock lobsters near the heatwave peak also appear to have been indirectly affected and have not recovered. Factors influencing the recovery rate from the heatwave appeared to be: species near their upper temperature range and/or sensitive to warming temperatures; spatial overlap between the warming event and species distribution; whether spawning stock was affected to the point of recruitment impairment; life-cycle duration of invertebrate (or habitat) species affected; and management intervention. This study provides a framework for managing the consequences of heatwaves on fisheries by highlighting the value of early identification of the event and its effect on fisheries and having flexible harvest strategies for early management intervention. This is particularly important as long-term increases in water temperatures will increase the frequency of marine heatwave events and the fisheries stocks would hav

According to the latest report on the state of World Food and Agriculture Organization fisheries and aquaculture (SOFIA, 2022), skipjack (Katsuwonus pelamis) and yellowfin tuna (Thunnus albacares) are among the five most caught finfish species of the world, with 2,827 and 1,569 thousand tons in 2020, respectively. The tropical purse seiners deploy large nets around tuna schools in the tropical waters of the world. This method targets three main tuna species, skipjack, yellowfin and bigeye (Thunnus obesus) tunas, which are mainly used for canning or frozen markets. This important fishery provides employment opportunities for many people in developing countries. Landings for the European long-distance fishery targeting tuna and tuna-like fishes from Indian Ocean, amounted to 303,638 tons valued at EUR 423.7 million (Prellezo et al., 2022), where the Spanish fleet of purse seiners targeting tropical tuna is the most important. The Spanish tropical purse seine fleet fishing in the Indian Ocean accounts for 26% of the skipjack and yellowfin tunas caught from Indian Ocean, which represent approximately 3% of worldwide catch for both species.
