Geosciences

This document summarizes the scientific projects that Uruguay is
currently developing in Antarctica. They are structured around four major
areas of work: Geosciences, Life Sciences, Physical Sciences, Humanities
and Social Sciences and Environmental Monitoring, constituting the first
four, areas of high priority study for the Scientific Committee on Antarctic
Research (SCAR).

GEOSCIENCES


SCAR-GIANT (Development of the Antarctic Geodetic
Infrastructure) and SCAR-KGIS (King George Island Geographic
Information System) projects.

The activities to be developed are framed in two international
cooperation projects promoted by SCAR: SCAR-GIANT (Antarctic Geodetic
Infrastructure) and SCAR-KGIS (King George Island Geographic
Information System). The main objective is to establish and maintain a
High Precision Geodetic Infrastructure, in order to be able to georeference
any geographical object located on the earth’s surface. With the
installation of semi-permanent and permanent Passive (boundary
markers) and Active (CORS) Stations, it is possible to study different
geodesic and geophysical components (tides, movements and cortical
deformations, marine currents, wind, temperature, atmospheric pressure,
humidity, others) as well as to carry out topographic, geodesic,
photogrammetric and geophysical surveys for different technical and
scientific purposes. At the same time, it is intended to implement a
Geographic Information System of King George Island (KGIS) with the
main purpose of maintaining an integrated and updated cartographic
and geospatial information base regarding King George Island. It is
expected to make a digital surface model, a digital terrain model, contour
lines every one meter (1m), an ortho-mosaic, and a 3D reconstruction of
the environment of the Artigas Antarctic Science Base.

Las actividades a desarrollar se enmarcan dentro de los Proyectos SCAR-GIANT y SCAR-KGIS. El objetivo principal es establecer y mantener una Infraestructura Geodésica de Alta Precisión, para poder georreferenciar cualquier objeto geográfico ubicado en la superficie terrestre. Con la instalación de Estaciones Pasivas (mojones) y Activas (CORS) semipermanentes y permanentes, es posible estudiar diferentes componentes geodésicas y geofísicas (mareas, movimientos y deformaciones corticales, corrientes marinas, viento, temperatura, presión atmosférica, humedad, otros) así como realizar relevamientos topográficos, geodésicos, fotogramétricos y geofísicos con diferentes fines técnicos y científicos. Se pretende, a su vez, implementar un Sistema de Información Geográfica de la Isla Rey Jorge (KGIS) con la finalidad principal de mantener integrada y actualizada una base cartográfica e información geoespacial referente a la Isla Rey Jorge. Se espera confeccionar un Modelo digital de superficie, un modelo digital de terreno, curvas de nivel cada un metro (1m), un ortomosaico, y una reconstrucción 3D del entorno de la Base Científica Antártica Artigas.

Este proyecto es desarrollado en coordinación entre el Instituto Geográfico Militar (IGM) y el Servicio de Oceanografía, Hidrografía y Meteorología de la Armada (SOHMA). Mediante la instalación de sensores, estaciones pasivas (mojones) y activas (CORS), se busca determinar con precisión la variabilidad a través del tiempo del Nivel Medio del Mar (NMM) en la Bahía Maxwell en proximidades de la Base Científica Antártica Artigas (BCAA), en primera instancia hasta completar un ciclo nodal (18,6 años). Por lo tanto el objetivo principal de este proyecto es investigar y aportar información fehaciente y concreta de la variabilidad del NMM en un contexto de Cambio Climático. Los datos obtenidos permitirán fortalecer el conocimiento del régimen mareal en la zona, ayudar en la predicción y publicación de la tabla de mareas para la BCAA, contribuir a la base de datos históricos de nivel medio del mar y apoyar actividades logísticas relacionadas con la línea de costa.

This project encompasses two sub-projects that are carried out by the Military Geographic Service (MGS) and the Navy Oceanographic, Hydrographic and Meteorological Service (SOHMA). Through the installation of sensors and passive (landmarks) and active (CORS) stations, the aim is to determine with precision the variability through time of the Mean Sea Level (NMM), in the first instance until completing a nodal cycle (18.6 years), mainly in Maxwell Bay near the Artigas Scientific Antarctic Base (BCAA). The data obtained will allow to know the tidal regime in the area, help in the prediction and publication of the tide table for the BCAA, contribute to the historical database of mean sea level, and support logistic activities related to the coastline.
