Abstract
Estas capacitaciones surgen a partir de un requerimiento que, en el año 2014, la Fundación Conociendo Nuestra Casa de Puerto Deseado (Provincia de Santa Cruz) le propuso al Grupo de Investigación Radar de Apertura Sintéticade la Universidad Tecnológica Nacional, Facultad Regional Haedo. Consistió en la preparación de unas charlas básicas sobre glaciología para ser dado a los alumnos de 4º Grado de las escuelas de Puerto Deseado y otras ciudades costeras con el objetivo de concientizar desde pequeños a los habitantes de dichas poblaciones. Esta capacitación se fue transformando en los años siguientes a partir del interés que mostraron algunos colegios secundarios de Buenos Aires, para impartirlos durante el ciclo lectivo. Es así, como desde el año 2017, los integrantes del grupo de investigación ofrecen de forma gratuita, clases sobre glaciología y su relación con el cambio climático para jóvenes estudiantes en escuelas secundarias. Primeramente, se buscó generar un contenido didáctico lo suficientemente sencillo como para ser comprendido por niños de 10 años de edad que incluyera tanto imágenes satelitales de la zona del campo de hielo como fotografías históricas y actuales de los diferentes glaciares. Esto fue posteriormente modificado y adaptado a oyentes adolescentes, quienes mostraron además especial interés por la temática del cambio climático. De esta forma, los alumnos pudieron adquirir conocimientos básicos tanto sobre las características principales de los glaciares, así como el retroceso de sus frentes debido a la modificación de las condiciones climáticas imperantes en la zona y en el mundo en general, además de conceptos sobre teledetección. Se usaron geotecnologías para visualizar los glaciares y complementar el texto que comprende su definición, estructura, morfología, evolución, ubicación y aspectos ambientales e históricos asociados de forma que los alumnos puedan tomar contacto con ellos. Se recurrió a imágenes ópticas de los satélites Landsat 3/5/7/8 y Sentinel-2A. Se obtuvieron composiciones en color natural y en falso color compuesto para el periodo 1981-2017 y se realizó un estudio multitemporal para resaltar el retroceso del Glaciar Upsala desde el año 1986 hasta la actualidad. Asimismo, se utilizaron mapas, fotografías históricas, esquemas explicativos e imágenes tomadas por los autores en diferentes estudios de campo realizados en el marco del grupo de investigación. Se fue agregando material específico de misiones satelitales argentinas como el lanzamiento del SAOCOM 1A, además de definiciones sobre el medio ambiente y los factores que lo modifican. La capacitación fue confeccionada de forma flexible pudiendo ser actualizada y dictada en escuelas de todo el país, debido a la enorme importancia que representan los glaciares como recurso hídrico de la Nación y como indicador de las alteraciones producidas en el ecosistema local debido al cambio climático global.
These training courses arise from a requirement that, in 2014, the Conociendo Nuestra CasaFoundation of Puerto Deseado (Province of Santa Cruz), proposed to the Research Group Synthetic Aperture Radarof the National Technological University, Haedo Regional Faculty. It consisted in a basic course on glaciology for 4th Grade students of Puerto Deseado schools and other coastal cities, in order to raise environmental awareness among the inhabitants of these populations. This course was modified in the following years due to the interest shown by some secondary schools in Buenos Aires, to be taught during the school year. This is how, since 2017, the members of the research group offer free classes on glaciology and its relationship with climate change, for young students in secondary schools. Initially, the objective was to generate teaching material simple enough to be understood by 10-year-old children, which included both satellite images of the ice field area and historical and current photographs of the different glaciers. This was subsequently modified and adapted to teenage students, who also showed special interest in climate change issues. Thus, students were able to acquire basic knowledge about not only the main characteristics of the glaciers, but also the retreat of their fronts due to variations of the prevailing climatic conditions in the area and in the world, besides remote sensing learning. Geo-technologies were used in order to track the glaciers and to complement the theory regarding to theirdefinition, structure, morphology, evolution, location and associated environmental and historical aspects, so that the pupils can acquaint themselves with remote sensing. Optical Landsat 3/5/7/8 and Sentinel-2A images were used. Compositions in true and false-colour were obtained for the period 1981-2017 and a multitemporal analysis was realized to highlight the Upsala Glacier’s retreat from the year 1986 up to the actuality. The course also includes maps, historical photos, explanatory schemes and imagestaken by the authors in fieldworks. Specific material from Argentine satellite missions such SAOCOM 1A launch was added to the teaching material, as well as definitions related to natural environment and the factors that modify it. The course was developed in a flexible way, so as to be updatable and dispensed to schools countrywide. Its main goal is to aware students about the enormous significance of glaciers as national water resources and as indicator of global climate change with the subsequent alteration of local ecosystems.
