The coastal zone is a unique geologic, ecological and biological domain of vital importance to a vast array of terrestrial and aquatic life forms-including humankind. Managing the plethora of rights, restrictions and responsibilities of resources within the marine environment and at the littoral zone has created one of the world’s most complex areas of management. Evidently effective administra...

The micro-scale and meso-scale ocean dynamic processes which are nonlinear and have large variability, have a significant impact on the fisheries, natural resources, and marine climatology. A rapid, refined and sophisticated observation system is therefore needed in marine scientific research. The maneuverability and controllability of mobile sensor platforms make them a preferred choice to est...

Launch of the Integrated Maritime Policy for the European Union in 2007 served as important factor that stimulates consolidation of coastal and marine information to support policy implementation. Policy’s action plan provides approaches for maritime governance, research and planning relevant to information. In particular, roadmap for maritime spatial planning stimulates development of coastal ...

Marine pseudoalteromonads represent a very promising source of biologically important natural product molecules. To access and exploit the full chemical capacity of these cosmopolitan Gram-(-) bacteria, we sought to apply universal synthetic biology tools to capture, refactor, and express biosynthetic gene clusters for the production of complex organic compounds in reliable host organisms. Here...

Ships at sea are affected by factors such as waves which will produce a swing phenomenon. By constantly measuring the attitude of the platform and the change in position, a control system is developed to eliminate all interferences and insulate disturbances to stabilize objects on the carrier and maintain dynamic attitude reference accurately. This paper explores controllers of marine platforms...

To aid legislators, resource managers, and the general public, this paper summarizes and clarifies some of the issues and options that the federal government and the state of California face in decommissioning offshore oil and gas production platforms, particularly as these relate to platform ecology. Both local marine ecology and political climate play a role in decommissioning offshore oil pr...

The corrosion fracture life of marine riser is investigated. Riser will be modeled as a long beam and the wave and current forces is estimated by short wave theory and modified Morison’s equation. Dynamic equilibrium equations of riser will be obtained on based of Euler theory. After bending stress calculation along the riser that includes effect of riser weight and platform motion, loading his...
