background: considering their specific adaption to marine milieus, marine actinomycetes constitute an excellent source for producing unique bioactive substances. they are also important sources of antibiotics and extracellular enzymes, geosmin, and enzymes with potent antibacterial and anticarcinogenic properties and low toxicity. the objective of this study is to isolate actinomycetes producin...

in this study marine sponges of inter tidal zone from hengam island persian gulf were collected by wading at low tides in eskeleh station at  locations 55˚ 53ʹ 40ʺ e & 26˚ 40ʹ 53ʺ n.for identifying identification of sponge samples, acid digestion method as a method of early detection and microtome section to identify the skeletal structure were used.all the identified sponges were from class de...

halophilic bacteria grow over a wide range of salt concentrations. in this study we aimed to isolate and screen out the halophilic bacteria and to determine their activity for production of the bioactive compounds. a total of 50 water, sediments and soil samples were collected from maharlu salt lake in southern region of fars-iran and subjected for isolation of the bioactive compound producing ...

this study reports the concentrations of important tracers of the marine environment, 210po and210pb, in different matrices from field samples collected at central adriatic sea (italy), a non-contaminatedmarine ecosystem. 210po concentration appears to decrease with increasing distance from the coast and asignificant difference in 210po concentrations in seawater samples at two different depths...

The characters of marine data, such as multi-source, polymorphism, diversity and large amount, determine it’s different from other data. How to store and manage marine data rationally and effectively to provide powerful data support for marine management information system and “Digital Ocean” prototype system construction is an urgent problem to solve. System planning different types of data, s...

iran has 1260 km of coastline that borders the persian gulf and the oman sea in the northwest indian ocean. marine algae are one of the natural resources in the marine ecosystem which produce a wide range of new secondary metabolites with various biological activities that play an important role in the pharmaceutical care. in this study the cytotoxic activity of 28 marine algae of chabahar coas...

this paper assesses the design guidelines of different classification codes for the liquefied natural gas carriers considering the effect of liquid sloshing. with regard the increasing importance of lng carriers in today’s marine transportation, and also considering that the marine accidents involve significant loss, classification societies by regulating national and international standards ai...

The Benguela Current Large Marine Ecosystem (BCLME) is situated off the west coast of Africa between 5-37oS, 0-26oE, and spans the three countries of Angola, Namibia and South Africa. It is one of the four major eastern boundary current upwelling systems of the world oceans (Hill et al. 1998), and although it has some similar characteristics to the other eastern boundary upwelling areas, a uniq...

We estimated the total marine and brackish-water fisheries catches from the Baltic Sea Large Marine Ecosystem, from 1950-2007, taken by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia and Sweden. Using the ICES electronic catch database as the ̳reported data‘ baseline, we added several IUU (Illegal, Unreported and Unregulated) catch components: ̳adjustments‘ (data source a...

Palytoxin (PTX) is a potent marine toxin that was originally found in soft corals from tropical areas of the Pacific Ocean. Soon after, its occurrence was observed in numerous other marine organisms from the same ecological region. More recently, several analogs of PTX were discovered, remarkably all from species of the dinoflagellate genus Ostreopsis. Since these dinoflagellates are also found...
