Abstrakt: Eddies occur almost everywhere in the oceans and play an important role in ocean circulation. They represent a large part of the ocean's kinetic energy and may indicate their transport and mixing of temperature and salinity. This study investigates the relationship between eddies, sea surface height (SSH), and sea surface temperature (SST) in the Indian Ocean in April 2020. We carry out the analysis using monthly average data for currents, SSH, and SST from the data portal Copernicus Marine Environment Monitoring Service (CMEMS) together with wind data from the National Centers for Environmental Prediction (NCEP) / National Center for Atmospheric Research (NCAR) for April 2020. From the results of this study, we found that two eddies occurred in Aceh waters (coordinates (93°E,5°N) and (98°E,6°N)) in the northern hemisphere. The two Eddies occur with minimal SSH contours in the middle. The direction of the eddies appears in the form of a current counterclockwise movement. Because it occurs in the Northern Hemisphere, the current movement is deflected to the right, resulting in upwelling. The occurrence of a cold SST in the middle of the eddies confirms the appearance of the two eddies. [ABSTRACT FROM AUTHOR]
