概要 |
The role of oceanography is very important for archipelagic countries, especially Indonesia. Indonesia's maritime activities, including shipping, fisheries, marine tourism, and coastal and marine envi...ronmental protection, greatly benefit from the comprehensive knowledge of ocean currents, water properties, and ocean ecosystems derived from oceanographic studies. Indonesia has quite a large water area and quite a lot of islands. This research aims to provide a better quantitative description of the spatial-temporal variability of sea surface height (SSH) in the Indonesian Sea. Stations in Batam waters, Riau Islands, Indonesia provided the data. The analysis was carried out using SSH satellite data with a spatial resolution of 0.25° × 0.25° at Copernicus Marine Service (CMEMS). We analyzed the variability of SSH values from 2021-2023, focusing on sample points in Batam. The results show a pattern of decreasing and increasing SSH values, with a significant influence on ocean currents and sea waves in the region. The distribution of SSH values varies each month, with some months showing high values. Local geographic factors, such as ocean current patterns and seabed topography, can influence the distribution of SSH values. RMSE analysis shows changes in the distribution pattern of SSH values from year to year. This study highlights the importance of geographic factors in analyzing the distribution of SSH values in certain water areas, as well as showing different trends in SSH values from 2021 to 2023 in Indonesian waters.
