First characterization of Easter Island inland watersusing remote sensing techniques

摘要

Easter Island is the farthest human-inhabited site from a continent, and due to this condition stud- ies on it are very scarce and restricted to basic field descriptions of its coastal marine and terrestrial ecosystems. The aim of the present study is to complete a first description of Easter Island’s inland waters using remote sensing techniques, specifically the GVMI index. The results revealed monthly fluctuations in water body and wet soil surface that are due mainly to rainy seasons. These results provide an interesting first step for other limnological studies in Easter Island and other sites with access problems.
