| Heinrich events (HEs) are dramatic episodes of marine-terminating ice discharge and sediment rafting during periods of cold North Atlantic climate. However, the causal chain of events leading to their occurrence is unresolved. Here, we demonstrate that enhanced surface melting of land-terminating margins of the southern Fennoscandian Ice Sheet (FIS) is a recurring feature of Heinrich stadials (HSs), the cold periods during which HEs occur. We use neodymium isotopes to show that the Channel River transported detrital sediments from the interior of eastern Europe to the Bay of Biscay in the northeast Atlantic Ocean at ca. 158–154 ka. Based on similar evidence from the last glacial period, we infer that this interval corresponds to the melting and retreat of... |

| Within the Sea of Marmara, the highly active North Anatolian Fault (NAF) is responsible for major earthquakes (Mw>=7), and acts as a pathway for fluid migration from deep sources to the seafloor. This work reports on pore water geochemistry from three sediment cores collected in the Gulfs of Izmit and Gemlik, along the Northern and the Middle strands of the NAF, respectively. The resulting data set shows that anaerobic oxidation of methane (AOM) is the major process responsible for sulfate depletion in the shallow sediment. In the Gulf of Gemlik, depth concentration profiles of both sulfate and alkalinity exhibit a kink-type profile. The Sulfate Methane Transition Zone (SMTZ) is located at moderate depth in the area. In the Gulf of Izmit, the low... |

| The structure and nature of the crust underlying the Camamu-Almada-Jequitinhonha-Sergipe-Alagoas basins System, in the NE Brazilian margin, were investigated based on the interpretation of 12 wide-angle seismic profiles acquired during the SALSA (Sergipe ALagoas Seismic Acquisition) experiment in 2014. In this work, we present two 220-km-long NW-SE combined wide-angle and reflection seismic profiles, SL 01 and SL 02, that have been acquired using 15 ocean-bottom-seismometers along each profile, offshore the southern part of the Sergipe Alagoas Basin (SAB), north of the Vaza-Barris Transfer zone. The SL 02 has a 150-km long inland continuation with 20 land-seismic-stations until the Sergipano Fold Belt (SFB). Wide-angle seismic forward modeling allows us to... |

| The authors regret a mistake on the value of δ13C of methane for one of the investigated gas samples. This concerns sample MRS-DV3-PE03, taken as end member and for which the correct methane δ13C value is -41.9‰ and not -34‰. The sample was collected at in situ pressure (~100 bars) from a CO2-rich seep, in a liquid state. The mistake likely results from a partial extraction (i.e. done by expansion of the sampler volume to allow vaporization) of the pressurized sample for subsampling. Additional analyses have been carried out from fully vaporized samples. This error has resulted in updating the geochemical diagrams used for the discussion, and revising both the gas origin for sample MRS-DV3-PE03 and the section entitled “Delineation of sources, reservoirs... |

| Le statut de département français fait de l’île de la Martinique une des régions ultra périphériques (RUP) de l’Union européenne. L’activité des navires de pêche qui exploitent sa ZEE s’inscrit dans le cadre de la politique commune des pêches de l’Union européenne, et la gestion des ressources partagées avec d’autres pays s’exerce dans le cadre des organisations internationales de pêche afférentes. Avec 1098 navires de pêche dont 1074 de moins de 10 mètres, la flotte de la Martinique représentait en 2009 16% de la flotte française. L’absence de données halieutiques depuis les évaluations de Gobert en 1989 a été identifiée à de nombreuses reprises comme un élément critique pour le suivi de l’évolution des activités de pêche et des ressources exploitées,... |

| Les résultats de ce travail concernent la France métropolitaine (façades Manche / Mer du Nord / Atlantique.) Ils sont établis à partir de l’activité de l’ensemble des navires de pêche professionnels inscrits au fichier Flotte de Pêche Communautaire (FPC) entre 2000 et 2011. Ce rapport donne une description des flottilles et des zones de pêche qui repose sur les résultats de deux analyses : l'une porte sur les données issues de la base SACROIS (présence d'au moins 1 kg de l'espèce considérée dans les captures annuelles de chacun des navires), l'autre fait intervenir la notion de ciblage de l’espèce (que l’on retrouve via les métiers pratiqués dans la base des calendriers d’activité du SIH). Enfin, dans le cadre de la proposition de la Commission d’une mise... |
