| Les conditions de milieu dans lesquelles s'effectue le développement de la mytiliculture en mer Noire étant très proches de celles existant dans le golfe du Lion, l'objectif principal de la mission était de pouvoir étudier et comparer: - la conception des filières mytilicoles et les solutions technologiques apportées aux problèmes de comportement par mauvais temps et de gestion de la flottabilité. - les moyens à la mer développés pour le travail des filières (bateaux et équipements spécifiques). - le traitement des coquillages après la récolte (stockage, lavage, contrôle sanitaire, commercialisation). La présence d'un industriel français de la mytiliculture dans la délégation, en la personne de Christian Malizard, avait également pour but de faire une... |

| The Romanian sector of the Black Sea deserves attention because the Danube deep-sea fan is one of the largest sediment depositional systems worldwide and is considered the world's most isolated sea, the largest anoxic water body on the planet and a unique energy-rich sea. Due to the high sediment accumulation rate, presence of organic matter and anoxic conditions, the Black sea sediments offshore the Danube delta is rich in gas and thus shows Bottom Simulating Reflectors (BSR). The cartography of the BSR over the last 20 years, exhibits its widespread occurrence, indicative of extensive development of hydrate accumulations and a huge gas hydrate potential. By combining old and new datasets acquired in 2015 during the GHASS expedition, we performed a... |

| A statistical evaluation of vertical current velocity profiles w(z) has been undertaken using data provided by current meter profilers. The calculation of profiles w(z) involves the estimation of the standard deviation of vertical current at each depth level, and the standard deviation of the statistical variability of that estimate. Profiles w(z) have been computed for the northwestern Black Sea, using current meter and CTD data from three surveys carried out during 1992-1994. The calculations show w(z) to have a two-layered structure, with zero values occurring in the main pycnocline. Such vertical current structures are consistent with a hydrodynamic model, whereby the current field is induced by buoyancy fluxes through the lateral basin boundaries.... |

| Holocene sediments taken from the south-eastern and western Black Sea have been investigated in relation to their geochemical, sedimentological and mineralogical characteristics. Their textures are characterized by their low amount of sand, upward-increasing silt and downward-increasing clay contents. While the terrigenous materials transported from Anatolian volcanic-based sources and European alluvial sediments form the shore deposits, the deep-sea sediments mainly consist of the marine biological production. The highest amount of organic carbon was deposited following the formation of anoxic conditions at the bottom until the beginning of the still continuing carbonate-rich coccolith (Emiliania huxleyi) deposition. The high metal concentrations are... |
