ABSTRAK Laut Andaman merupakan perairan laut dalam, dengan kedalaman ratarata 1100 m. Eddies ialah arus yang berbentuk lingkaran yang dapat terbentuk di lautan mana saja. Eddies juga dikenal sebagai salah satu sumber utama keberagaman dalam proses biologi dan biogeokimia di lautan lepas. Penelitian ini bertujuan untuk mendeteksi eddies selama bulan April (Intermonsoon) 2008. Berdasarkan informasi angin dari National Centers for Environmental Prediction (NCEP) / National Center for Atmospheric Research (NCAR), Sea Surface Height (SSH) dan arus geostropik yang diperoleh dari data altimeter yang kemudian divisualisasi untuk mengamati eddies. Hasil pengamatan menunjukkan bahwa kekuatan dan arah angin menentukan variasi SSH. SSH yang berbeda menyebabkan dinamika arus geostropik dan eddies. Pada April 2008, terdapat enam eddies yang tersebar di sekitar Laut Andaman, eddies Cyclone eddies dapat dilihat pada Teluk Benggala, di Teluk Martaban, selatan Pulau Andaman dan di utara pulau sumatera, sedangkan anticyclone eddies terbentuk di dekat Perairan Yangon (Myanmar) dan di barat Pulau Sumatera. Kata kunci : Angin, Arus permukaan laut, Eddies, SSH dan Laut Andaman ABSTRACT The Andaman Sea is deep sea waters, with an average depth of 1100 m. Eddies are circular currents that can form in any ocean. Eddies are also known as one of the main sources of diversity in biological and biogeochemical processes in the open ocean. This research aims to detect eddies during April (intermonsoon) 2008. By using wind information from the National Centers for Environmental Prediction (NCEP) / National Center for Atmospheric Research (NCAR), Sea Surface Height (SSH) and geostrophic currents obtained from data altimeter which is then visualized to observe eddies. The results of the observation show that the strength and direction of the wind determine the variation of SSH. Different SSHs cause the dynamics of geostrophic currents and eddies. In April 2008, there were six eddies in the Andaman Sea, Cyclone eddies can be seen in the Bay of Bengal, in the Martaban Bay, south of the Andaman Islands and the north of Sumatra Island. The anticyclone eddies are formed near the waters of Yangon (Myanmar) and west of Sumatra Island. Keywords: Andaman Sea, Wind, surface currents, SSH and eddies.
