Abstract

Geostatistical methods for the evaluation of anthropogenic impact in marine bottom J. Axis-Arroyo* & J. Mateu^ ^Centra de Investigation y Estudios Avanzados del IPN Unidad Merida, Merida, Yucatan, Mexico * Department of Mathematics, Universitat Jaume /, Castellon, Spain Abstract Most modern environmental impact studies are based on image analysis generated by remote sensing due to the capacity to analyze large areas with a high confidence. Though these techniques are good enough in terrestrial environments, the absorption effect of light in water limits their use in aquatic environments, particularly in marine bottom analysis. The biological coverage studies in marine bottom are based on the use of photographic and videotransect techniques which generate point process data and consequently require of spatial distribution models. The geoestatistical methods allow one to use these point pattern values to develop an analysis of the spatial behaviour and to estimate pointwise t
