In this study an optimal weather routing model (OWR) considers the meteorological and oceanographic information, ship’s characteristics combined with adaptive Bacterial Foraging Optimization Algorithm will be proposed and applied for ship’ navigation. The simulation results will be presented to show the effectiveness as well as the reliability of this model. The OWR will make it possible for safe navigation, effective operation, energy efficiency and reduce emission from vessel.

Ebook "Essentials of oceanography (Fifth edition)" was written to provide an interesting, clear, current, and reasonably comprehensive overview of the marine sciences. It was designed for students who are curious about Earth’s largest feature, but who may have little formal background in science. Oceanography is broadly interdisciplinary; students are invited to see the connections between astronomy, economics, physics, chemistry, history, meteorology, geology, and ecology—areas of study they once considered separate.

The system is designed with two servers connected in a cluster, so it has high stability. Alerts are delivered to users quickly using push notification technology, suitable for personal computers and iOS and Android mobile devices. The system is in line with the trend of Vietnamese people using mobile devices to monitor weather information today. Therefore, this will be an effective source of extreme weather warnings that VNMHA can use.
