Operational ocean observing system (OOOS) can meet the needs of marine disaster prevention and reduction, safeguard socio-economic development in coastal zones, and promote marine resource exploitation. As a solid foundation for the establishment of the OOOS, operational ocean observing equipment (OOOE) is attached great significance across the world. Three kinds of OOOEs in China are introduced and...
Accompanied with the evolution of sea floor exploration technologies, marine samples and corresponding geochemical data increased dramatically. These distributed data interconnected together within complex and evolving relationship. Heterogeneity of format, syntax and semantic becomes obstacle to knowledge integration, transmission and sharing. In order to collect and integrate these fragmented piece...
Turbulence plays a crucial role in ocean dynamics and global biogeochemical cycles through redistributing heat, salt and nutrients across isodensity surfaces. Conventionally, most of microstructure measurements were conducted with vertical freefall profilers. In order to provide both a very high resolution vertical distribution of turbulent quantities and the long term series, a novel instrument MRVP...
The last decade can be considered an embryonic period for seafloor networks with the introduction of sizeable networks off the West Coast of Canada, off the West Coast of the United States and in the Mediterranean Sea, as well as smaller networks spread throughout the world's oceans. The amount of data currently available is expected to pale in comparison to future prospects as the infrastructure...
We performed numerical and physical experiment with a marine monostatic electromagnetic (EM) survey system, which is developed primarily for exploration of seafloor mineral deposits. The system is a multi-frequency EM system housed to endure high pressure in deep sea up to 2000 m. To keep stable altitude of the system from the seafloor in rough seafloor topography condition, the system is connected...
An oceanographic research vessel is a special vessel designed to conduct research at sea on relevant natural elements and characteristics of the ocean and acquire its basic parameters with professional researchers and specialized equipment on board. It features an integration of the ship platform, research equipment and professional researchers. It is estimated that our country owns at least 50 oceanographic...
Development of a new sensor is driven by the need for a new measurement which in turn is driven by the need for new understanding of some phenomenon. The process of bringing a new sensor on line, validating it, and gaining confidence in its behavior is one familiar to the authors but bears telling. The principal author offers the partly told story of SCIMP, RiNo, BASS, and MAVS to illustrate this...
Offshore oil and gas industry has been active in the North Sea for more than half a century, contributing to the economy and facilitating a low oil import rate in the producing countries. The peak production was reached in the early 2000s, and since then the oil production has been decreasing while the water cut has been increasing rapidly. The water dominates some of the wells and a water cut of...
