Análise comparativa dos dados geoambientais da Ilha do Farol, no Atol das Rocas

Abstract

The Brazilian Exclusive Economic Zone (ZEE) area has a diversity of geomorphological features which differs according to the formation processes and elements that constitute them. As one of these elements, the Rocks Atoll, is the only atoll in the South Atlantic, located at 267 km from Natal/RN and 148 km from the island of Fernando de Noronha/PE was the object of study of this research. Considering its geographic isolation, vulnerability and its great biodiversity, the Biological Reserve –ReBio at Rocas Atoll is the first Conservation Unit – UC Marine in Brazil and since then it has been monitored and inspected for full protection against predatory fishing. Using the geoenvironmental analysis, we seek to understand the dynamics of the elements that constitute the landscape in two points at Farol’s Island. Throughout November 2020, we collected meteorological, hydrodynamics (at high tide) and morphological data (at low tide) to understand how this dynamic occurs. Through this, we realize that sedimentary remobilization occurs intensely, mainly through meteorological and oceanographic agents, which transfigure the local landscape, requiring long-term research to consolidate knowledge and thus have a database about the sedimentary dynamics of Farol’s Island.
