                         sensors representing the period of 36 years (1972-2008) were used 
                         to quantify the area changes in the coastal islands at the 
                         Amap{\'a} State littoral. The mosaics were built from: RadarGems 
                         1000 images, band X, from RADAMBRASIL project; CIRCA data from 
                         1999 and 2000 from Global Land Cover Facility and a LANDSAT TM5 
                         mosaic elaborated by SIPAM. The mosaics were registered among each 
                         other based on the CIRCA data 2000. The coastline was extracted on 
                         hand using as a geoindicator of changes in the coastline marker, 
                         the boundary between the vegetation and the water (or intertidal 
                         zone). The results presented accretionary, erosional and migration 
                         patterns of the coastal islands, according its geographical 
                         positioning at the littoral, and, according the natural 
                         environmental constraints. The islands under marine influence as 
                         Maraca and Jipioca the erosional processes predominate with a 2.7 
                         km (± 0,0769 km) maximum linear erosion between 1972 and 2008 
                         northward Maraca Island. The coastal islands under 
                         fluvial-estuarine influence as the islands belonging to the 
                         Bailique Archipelago, Pedreiras, Santana, Periquitos and Cajari 
                         the accretionary processes dominate with a maximum 9,8 km (± 
                         0,0769 km) between 1972 and 2008. Natural hydrodynamic and 
                         oceanographic factors are considered as the main dynamic 
                         responsible by changes in the coastal islands.",
