Kumpulan Penyelidikan Inovasi Geomatik (GnG), Fakulti Alam Bina dan Ukur (FABU), Universiti Teknologi Malaysia (UTM) akan menganjurkan Program Bincang Geodesi Demi Malaysia bersama Bahagian Ukur Geodetik, Jabatan Ukur dan Pemetaan Malaysia (JUPEM). Sesi perbincangan ini merupakan satu platform jalinan kerjasama dan kolaborasi antara Program Geoinformasi, FABU, UTM dengan JUPEM bagi menyusun strategi untuk memantapkan bidang geodesi di Malaysia.
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tidal phenomena are not limited to the oceans, but can occur in other systems whenever a gravitational field that varies in time and space is present.
Tides vary on timescales ranging from hours to years due to a number of factors, which determine the lunitidal interval. To make accurate records, tide gauge at fixed stations measure water level over time. Gauges ignore variations caused by waves with periods shorter than minutes. These data are compared to the reference (or datum) level usually called mean sea level.
Precise determination of a “mean sea level” is difficult because of the many factors that affect sea level. Instantaneous sea level varies quite a lot on several scales of time and space. This is because the sea is in constant motion, affected by the tides, wind, atmospheric pressure, local gravitational differences, temperature, salinity, etc. The easiest way this may be calculated is by selecting a location and calculating the mean sea level at that point and using it as a datum. For example, a period of 19 years of hourly level observations may be averaged and used to determine the mean sea level at some measurement point.
UTM-GnG hosted a research colloquium on geomatics, geodesy and hydrography with Kangwon National University (강원대학) and Changwon National University (창원대학교) in UTM Skudai on 13 August 2023. This GnG-Korea Colloquium enables researchers and students to showcases not only their specialized research in their respective surveying fields but also allowing us to discuss and exchange knowledge as well as setting the future cooperation in between the universities in the international arena.
