| The new genus and species, Dicrotrichura tricincta, is described from deep mud (1220 m) in the Ligurian Sea (western Mediterranean). It is the first tantulocaridan not found to be attached to a crustacean host but free living in the sediment. It is assigned to the Deoterthridae on the basis of the absence of a rostrum, the abdominal segmentation and the characteristic cephalic pore pattern. It can be distinguished from all known tantulocaridans in the presence of peculiar, bi-articulated caudal setae and the difference in thoracopodal setation between leg 2 and legs 3-5. Some new structures located on the attachment disc are described for the first time. D. tricincta is the second tantulocaridan to be recorded from the Mediterranean. |

| A new genus of parthenopid crab, Garthambrus gen. nov., characterised by a broad carapace with strongly raised branchial and gastric regions, distinctive rostrum, sub-cylindrical ambulatory meri and a long distal segment of the second male pleopod, is established for six deep water species from various parts of the Pacific. A new species, Garthambrus posidon spec, nov., is also described from depths of between 480 to 600 m off the Seychelles in the Indian Ocean. It differs from its closest congener, G. poupini (Garth, 1993), in having a proportionately broader carapace, less granulated carapace and chelipedal surfaces, and in the form of the carapace regions. |

| The blackspot sea bream (Pagellus bogaraveo) used to be a major species in the landings from the Bay of Biscay up to the early 1980s. Nowadays, it is only a minor bycatch. Up to the mid-70s, more than 15 000 tonnes of blackspot sea bream were landed annually in Spanish and French ports. Then, catches declined sharply from 1975 to 1985 and have stayed at low levels ever since. Here, the full history of the fishery collapse is described using time-series of landings since the 1900s. Fishing mortalities of the main demersal stocks (hake, anglerfish, sole) were in the range 0.2-0.5 during the last 30 years. It is likely that the blackspot sea bream stock was exploited at similar levels, which are shown here to be unsustainable. The blackspot sea bream is... |

| We present here a unique oceanographic and meteorological dataset focus on the deep convection processes. Our results are essentially based on in situ data (mooring, research vessel, glider, and profiling float) collected from a multi-platform and integrated monitoring system (MOOSE: Mediterranean Ocean Observing System on Environment), which monitored continuously the northwestern Mediterranean Sea since 2007, and in particular high-frequency potential temperature, salinity and current measurements from the mooring LION located within the convection region. From 2009 to 2013, the mixed layer depth reaches the seabed, at a depth of 2330m, in February. Then, the violent vertical mixing of the whole water column lasts between 9 and 12 days setting up the... |

| After the four years of development of the modern maximum depth submersible, JAMSTEC has successfully completed the training dives of "SHINKAI 6500", a new manned submersible whose maximum operating depth is 6,500 meters, from June to October in this year. "SHINKAI 6500" was constructed by Kobe Shipyard and Machinary Works of Mitsubishi Heavy Industries Ltd. (MHI) and marked 6,465m and 6,527m dives in the Japan Trench during the sea trials with the support "YOKOSUKA" (built by Kawasaki Heavy Industries Ltd.) in August 1989. This paper presents the results of the sea trials, training dives and the features of "SHINKAI 6500" with her supporting technologies. |

| Reconstructions of Mediterranean ocean temperature fields back to 1950 show a proxy relationship between heat content changes in the North Atlantic and the Western Mediterranean Deep Water ( WMDW) formed in the Gulf of Lions in winter, because of consistent air-sea heat fluxes over these areas, strongly correlated to the North Atlantic Oscillation ( NAO). |

| With the advent of deep submergence research vessels (DSRVs) biological and ecological studies of ocean deeps have made great strides. Especially these submersibles allowed to conduct physiological and biochemical experiments on benthic fauna directly on the bottom or on board with alive retrieved animals. A second great interest is the possibility to work in chaotic areas and on microenvironments. Without DSRVs most of measurements and observations obtained on hydrothermals vents would had been impossible. We will present the different equipment designed for the two French DSRVs used during the cruises conducted by the Departement "Environnement Profond" de l'IFREMER to study hydrothermal and "normal" deep-sea ecosystems. We will discuss the new devices... |

| The gelatinous macroplanktonic organisms living in the deep sea can only be studied with manned submersibles. There is presently in increasing interest in the study of the role of this part of the pelagic ecosystem, because they are strongly involved in the transformation of the particulate organic matter. Their transparency, small size and mobility present technical challenges, unanticipated by the designers of the first submersibles, aimed at the sea bottom observation. Despite these limitations, the use of conventional submersibles has brought very interesting results. It is hoped that engineers will take into account the requirements of pelagic observations in the design of future submersibles. |

| At the end of 1999 there were 233 offshore oil and gas fields in production in the West African region between Angola and the Ivory Coast. These fields currently produce some 3.1 million barrels of liquids per day. The region thus bears itself well in comparison with other shallow water areas of the world such as the North Sea and South East Asia. But it is the immense promise of the giant deepwater 'elephant' fields that is fuelling the current boom in exploration and development in the region and raising the levels of investment coming into it. |
