This article introduces some modern navigation system,such as ECDIS,AIS,GPS/GIS/RS,GMDSS,etc. and elaborates the applications of information technique in the field of navigation as well as the components and advantage of future navigation system. Also it displays the tendency of advanced science and technique applied in modern navigation.
Electronic chart display and information system (ECDIS) are a part of modern navigation style ,ECDIS is not only capable of display the navigation-related information in real-time but also supporting other advanced functions such as route planning, route monitoring and automatic alarm, The integration of maritime safety information into ECDIS has become a major issue common to International Maritime Organization (IMO), International Hydrographic Organization (IHO) and World Meteorological Organization (WMO).
It's a pity that the colliding accidents between vessels increased year by year in spite of the continuous development of the modern navigation technology, orientation and navigation system as well as the seafarers quality.
Though the level of modern navigation equipment and technology is much better than before, human factor is still the main reason to cause accidents. The complementation of STCW Convention 1995 revision and the ISM code have reduced the occurrence of the accidents resulting from human factor to a certain degree, nevertheless, human factor will still be the significant point in research.
Meanwhile, the Maritime English has been becoming the barrier of Chinese seafarers tending forwards the world and restricting the development of our higher navigation education and training. The existing mode of Maritime English teaching has not adapted to the requirements of modern shipping.
The p aper,analyzing the functions of AIS and ECDIS,provides the idea of using the equipments of AIS and ECDIS to solve t he problem of information collectio n,which is expected to do good to research and development of automatic collision -avoiding system.
Understanding the dynamics of organic matter in modern marine water columns greatly favors the geobiological evaluation of hydrocarbon source rocks.
Through the contrast of the occurrence of the highly mature OM in the black shales with that of the immature ones in modern marine continental margin sediments, some scientific problems are proposed, which are worth to study further in detail.
14C and13C Isotope concentration in modern marine mussels from sedimentary habitats
They account for about 11% of the total input of terrestrial carbon into the ocean and 15% of the total carbon accumulating in modern marine sediments.
Most authors assume that cyanobacteria-associated microbialitic structures described from Shark Bay, Western Australia, and Exuma Sound, Bahamas, represent modern marine analogues for Precambrian stromatolites.
In order to reduce the random errors involved in celestial observations and to increase the accuracy of the celestial fix, so as to meet the requirements of modern navigation, this paper proposes the design of a new-type sextent, which can give readingsof the mean values of both the altitudes of tho celestial body and the times of observations.
