چکیده: حمل و نقل دریایی ار آنجا صاحب اهمیت شده است که بیشتر کره زمین را آب فراگرفته و تا پیشرفت علم تنها وسیله ارتباطی جوامع دریا و خشکی بوده است حمل و نقل دریایی ار اهمیت بسیاری برخوردار شده است به طوری که از راه دریا بیش از 80% از کل تجارت جهان صورت می پذیرد؛ اما این امر با مشکلات بسیاری به خصوص از لحاظ اجرایی روبرو بوده است ؛ به این دلیل و بسیاری از دلایل دیگر، مراکز مرتبط با حمل و نقل دریا...
A summary of knowledge and recommendations for the conservation of marine birds and their habitats throughout the California Current Large Marine Ecosystem.
The outfall system is a medium to discharge the liquid waste generated by desalination plants, refineries and power plants to the marine environment. Optimal design and operation of an outfall system reduces the concentration of pollutants returned to the marine environment. Numerous researches have been carried out to study the different elements of outfall systems and related design basics. T...
Coastal ecosystems of Bushehr are shallow environments subject to human impacts, including shrimp aquaculture and urban expansion activities. A spatial-temporal study was conducted in order to assess the actual ecological status of the creeks, estuary and marine sites on the basis of their taxonomic composition and density of mesozooplankton. Zooplankton species distribution and abundance data ...

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...
In recent years, unmanned vehicles have intensively been developed to reduce risk on human life for marine applications. Predicting the dynamics behavior of an autonomous underwater vehicle is important during the vehicle’s design phase. In other words to design an AUV, one must clarify its maneuverability and controllability based on a mathematical model. The mathematical model contains variou...
