The marine environment is known as a rich source of chemical structures with numerous beneficial health effects. Among marine organisms, marine algae have been identified as an under-exploited plant resource, although they have long been recognized as valuable sources of structurally diverse bioactive compounds. Presently, several lines of studies have provided insight into biological activitie...

The Great Barrier Reef Marine Park was established to provide for conservation and ecologically sustainable multiple use of 344,400 km2 of a large marine ecosystem. Management is based on multiple use, with zoning as a fundamental component of marine spatial planning. The legislative framework, including a specific Act and Regulations, address the objectives of ecosystembased, integrated manage...

The ocean is tremendously diverse and species-rich. It is the home of countless organisms living in very different ecosystems. Fish are a key component of marine biotic communities. Fish is highly nutritious, tasty and easily digestive. It is much sought after by a broad cross-section of the world’s population particularly in developing countries. Monitoring the quality of fish is essential for...

Natural products have been regarded as important sources that could produce potential chemotherapeutic agents. In the search for new bioactive entities, investigations were expanded to marine habitats. Mankind has known for the last several thousand years that marine organisms contain substances capable of potent biological activity. However, the first serious investigation of marine organisms ...

in dynamic analysis of floating structures, the designer needs to know the wave forces due to incident and scattered waves on the structure. in this work, the flow field around the body is solved based on the potential theory with considering the free surface and sea bed effects. using this theory, the wave forces exerted on two typical sea buoys with spherical and disc-type bodies are determin...

Feeding habits of Caspian marine shad Alosa braschnikowii (Borodin, 1904), inhabiting in the western part of Caspian Sea such as prey spectrum and seasonal dynamics have been studied. As in other parts of Caspian Sea, throughout the year, the main hunt of Caspian marine shad constituted kilkas, gobies and shrimps while other groups of zoobenthos were represented in a lesser extent. Importance o...

Background and Aims: Marine Actinomycetes are gram-positive bacteria that sometimes are free, saprophytic or plant and animal-associated, including marine sponges. More than 75% of antibiotics and antimicrobial compounds are produced by actinomycetes. In recent years, due to the need for new drugs, marine microorganisms have been considered as new sources of potential production of significant ...

gravity acceleration data have grand pursuit for marine applications. due to environmental effects, marine gravity observations always hold a high noise level. in this paper, we propose an approach to produce marine gravity data using satellite altimetry, high-resolution geopotential models and harmonic splines. on the one hand, harmonic spline functions have great capability for local gravity ...
