| The EGIM aims to set up a number of ocean locations where the same set of core variables, including temperature, conductivity, pressure, dissolved O2, turbidity, ocean currents, and passive acoustics, are measured homogeneously: using identical hardware, the same sensor references, the same qualification methods, the same calibration methods, the same data format and access, and the same maintenance procedures. The EGIM provides all the services required to ensure the best measurement quality and long-term reliability in line with the Best Practices Handbook by FIXO3 and ESONET-EMSO Label, these services being sensor power distribution, time stamping, data storage and backup, protection against the environment and against fouling and bi-directional... |

| The Arctic Ocean is a fundamental node in the global hydrological cycle and the ocean's thermohaline circulation. We here assess the system's key functions and processes: 1) the delivery of fresh and low salinity waters to the Arctic Ocean by river inflow, net precipitation, distillation during the freeze/thaw cycle and Pacific Ocean inflows; 2) the disposition (e.g. sources, pathways and storage) of freshwater components within the Arctic Ocean; and 3) the release and export of freshwater components into the bordering convective domains of the North Atlantic. We then examine physical, chemical or biological processes which are influenced or constrained by the local quantities and geochemical qualities of fresh water; these include: stratification and... |

| Oceans, coasts, and islands are essential to global sustainable development. The oceans, comprising 72% of the earth’s surface, play an essential life-support function without which life on earth would not be possible. 50% of the world’s population lives in coastal areas, and 44 of the world’s nations are small island developing States (SIDS) which are especially dependent on the oceans. Human populations everywhere depend on the oceans for food, energy, transportation, tourism, and other uses. Oceans, coasts, and islands thus do not represent a special or sectoral interest and concern—they are essential to global well-being. Achieving sustainable development in oceans, coasts, and islands thus would go a long way towards achieving global sustainable... |

| The seabed hosts a lot of mineral resources, sand and gravel, phosphorite, sulphur, coal oil and gas manganese nodules and sulphide nodules which had been exploited for a long time. However, much more had been known in the last twenty years when a reasonable but still incomplete inventory of these minerals and materials were made. These deep sea with vast potential resources are however in competition with the onshore supply. The future development of these minerals depends largely on international markets, need for strategic materials and cost of production compared to onshore deposits. This brief presentation is a summary of these resources and their current status. It must however be emphasized that with improved technology and the concern for the... |

| For most activities, a relatively low level of exertion is required. While the ship will sometimes dock for a dry landing, you will need to climb into and out of Zodiacs for certain excursions ashore and for some snorkeling and most diving activities. Staff and crew will be on hand to assist. On shore excursions, you must be able to walk moderate distances in villages, towns, forests, and on beaches, occasionally over rough terrain. Opportunities will be available for leisurely strolls, as well as optional hikes requiring more exertion. Birders may participate in ornithological excursions. Our expedition staff and renowned lecture team of naturalists and historians will accompany you throughout shore and afloat. Average daily temperatures will be in the... |

| The importance of the marine environment to human existence makes it imperative that information models represent the multidimensional nature of reality as closely as possible in order to facilitate good governance. Information for a jurisdiction, on the effects of its formal law and community interests on the marine environment (e.g. nature and spatial extents and the rights, responsibilities, and restrictions etc.) would be stored in a marine cadastre. Other information on the physical, biological, socio-cultural and economic nature of the environment may be linked to the cadastre to give it a multipurpose function. This paper has the following objectives: 1. To highlight new spatial information technologies that facilitate the retrieval of various... |

| This paper addresses the question of the eventual control of barium concentration in seawater by an equilibrium with barite. For this, we have used a new thermodynamic model to compute the barite saturation index of ocean waters, mainly from GEOSECS data. Our results show that equilibrium between barite and seawater is reached in a number of places: cold surface waters of the Southern Ocean, waters at intermediate depths (2000-3500 m) in the Pacific, deep waters (2000-3500 m) of the Gulf of Bengal. The only samples for which a slight barite supersaturation is found are the surface waters at GEOSECS station G89 in the Weddell Gyre. Besides these locations, the rest of the world's oceans is undersaturated, as was established by Church and Wolgemuth [Church,... |
