Glacier retreat is considered a clear sign of global climate change. Although glaciers are retreating globally, comparatively little research has assessed how vegetation changes in recently deglaciated areas. The research objectives were to: 1) quantify patterns of landcover change of five classes—ice, rock, tree, shrub, and herbaceous at two glacier forefronts in Glacier National Park, and 2) determine the environmental and terrain factors that affect vegetation change at the deglaciated areas. Landsat imagery of the study locations in 1991, 2003, and 2015 were classified and validated using ground truth points and visual interpretation for accuracy. To identify terrain and environmental factors that influence change, we modeled change from nonvegetated surfaces to vegetation (code=1) and the stable non-vegetation class (code=0). Results revealed elevation, slope, topographic moisture, geology, and aspect to be associated with increased vegetation over time at Jackson Glacier forefront. Elevation, slope, solar radiation, and geology were significant at Grinnell Glacier forefront, indicating some geographic differences in important factors. New case studies on vegetation change in recently deglaciated regions can deepen our knowledge about how glacier retreat at local scales results in recharged ecosystem dynamics. This study provides further insight on the future of alpine ecosystems as they respond to global climate change and a compelling new perspective on the future of the Park. Additionally, we demonstrate the benefits of using remote sensing applications to study land cover change as a proxy for vegetation colonization, especially in remote mountainous environments.

Повний текст джерелаAndean glaciers are amongst the fastest shrinking and the largest contributors to sea level rise in the world. They also represent crucial water resources in the vast semi-arid portions of this large Andes Cordillera (10°N-56°S), sustaining river runoff during dry periods and buffering the effects of droughts. Despite the widespread shrinkage of these glaciers, direct measurement of glacier fluctuations in the Andes are sparse, short-termed and in many cases incomplete, preventing the accurate quantification of recent ice loss for the entire mountain range. Comprehensively quantifying the magnitude of this loss at different special scales is crucial to better constrain future economical, ecological and social impacts. First, we evaluated the performance of a methodology to calculate glacier mass changes on Andean glaciers using time series of digital elevation models (DEMs) derived from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) stereo images. Over our validation zone, the Northern Patagonian Icefield, we found strongly negative icefield-wide mass balance rates of -1.06 ± 0.14 m w.e. yr-1 for the period 2000-2012, in good agreement with estimates from earlier studies and with a second independent estimate (-1.02 ± 0.21 m w.e. yr-1) obtained by differencing the better resolved Shuttle Radar Topography Mission (SRTM) DEM with a Satellite pour l'Observation de la Terre 5 (SPOT5) DEM. Importantly, this work permitted us to (i) validate "ASTER monitoring Ice towards eXtinction" (ASTERIX) method over the Andes; (ii) confirm the lack of penetration of the C-band SRTM radar signal into the NPI snow and firn except for a small high altitude region (above 2900 m a.s.l.) with negligible effects on NPI-wide mass balance; and (iii) provide the basis for an analysis of NPI mass balance changes during different sub-periods between 1975 and 2016 using additional DEMs. Then, we processed more than 30000 ASTER DEMs to calculate the integrated volume of ice lost by Andean glaciers during the past two decades. Andes-wide mass loss amounts to -22.9 ± 5.9 Gt yr-1 (-0.72 ± 0.22 m w.e. yr-1) for the entire period (or -26.0 ± 6.0 Gt yr-1 including subaqueous losses). All regions show consistent glacier wastage, with the most negative mass balance rates in the Patagonian Andes (-0.78 ± 0.25 m w.e. yr-1) and Tropical Andes (-0.42 ± 0.24 m w.e. yr-1). Relatively moderate loss (-0.28 ± 0.18 m w.e. yr-1) is measured in the intermediate regions of the Dry Andes. The inter-decadal patterns of glacier mass loss is an important contribution of this work, observed for the first time at an Andes-wide scale. We observe steady thinning rates in the Tropics and south of 45°S. Conversely, glaciers from the Dry Andes were stable during the 2000s, shifting to drastic thinning rates during the 2010s, coinciding with conditions of sustained drought since 2010. The evaluation of the imbalanced glacier contribution to river discharge during these two decades revealed that glaciers partially helped to mitigate the negative impacts of this sustained drought in the Dry Andes. The results obtained in this thesis contribute to the understanding of recent Andean glacier evolution at a local, regional and Andes-wide scale. We provide a high-quality, multi-decadal dataset that will be useful to constrain the diversity of present 21st century Andes-wide mass loss estimates, in the pursuit of the good calibration of glaciological and hydrological models intended to project future glacier changes and to improve water resource management in the Andes

Повний текст джерелаLa variabilidad del clima durante el último milenio (A.D 1000 - 2000), permitió que diversos glaciares de montaña a escala global hayan experimentado su máximo crecimiento en térmi- nos de su masa, respecto a actuales condiciones. Las causas climáticas de este crecimiento glaciar se relacionan con La Pequeña Edad de Hielo (PEH; A.D 1500 - 1850). Este periodo de interés paleoclimático global ha sido bien documentado en el hemisferio Norte, contrario al hemisferio Sur.. Más aún, existe un desconocimiento profundo acerca de cómo, mecanismos climáticos que actualmente afectan el clima de regiones como los Andes Mediterráneos de Chile y Argentina (AM; 30-37 S), como El Niño Oscilación del Sur, hayan afectado el balance de masa glaciar y las variaciones temporales de la línea de equilibrio altitudinal (ELA) duran- te dicho intervalo. La PEH es un antónimo a lo que acontece actualmente con los glaciares de montaña, donde en regiones como los AM diversos estudios han identificado un severo retroceso. El balance de masa glaciar (MB) y su ELA está influenciado por los cambios en la temperatura del aire, elevación de la Isoterma de 0C y las precipitaciones. La presente tesis doctoral consta de dos capítulos y un capítulo introductorio. Un primer capítulo exhibe las tendencias de las variables climáticas que actúan directamente sobre el MB, y mencionadas anteriormente. Un segundo capítulo, presenta una modelación de la ELA durante A.D 1500 - 1848 mediante un modelo forzado por tres modelos climáticos globales (GCMs). Se estudió las relaciones entre las variaciones temporales en la Temperatura Superficial del Mar (SST) del Océano Pacífico y la variabilidad temporal de la ELA. La temperatura media se ha in- crementado significativamente durante enero, febrero, marzo, y desde agosto a noviembre, considerando 1969 - 2016. La temperatura mínima, por su parte, se ha incrementado signifi- cativamente durante enero y mayo, mientras que la temperatura máxima, excepto en mayo, julio y septiembre, se ha incrementado significativamente durante 1969 - 2015. La isoterma de 0oC (ISO0) registró un incremento significativo en enero, marzo y anual durante 1858 - 2015. Tendencias en la ISO0 (años 2000 - 2015) exhiben un incremento significativo durante enero, mayo, junio y agosto. La precipitación (pp) de abril a septiembre registró una ne- gativa y significativa tendencia desde 1876, con reducciones significativas durante los meses de mayo, junio y julio. Entre 1981 - 2015, una significativa reducción ha sido registrada en la pp de abril a agosto. La ELA anual durante la PEH registró una elevación de 3775 m. Una menor elevación de la ELA fue identificada durante A.D 1640 - 1670 y 1800 - 1948. Contrariamente, una mayor elevación de la ELA fue identificada durante A.D 1550 - 1575. Propiedades espectrales de la ELA modelada indican significativas señales de entre 2 - 7 años de periodicidad, y también señales decadales a multi decadales. Significativas señales espec- trales fueron también obtenidas con el primer modo de variabilidad de la SST región Niño 3.4. Además, correlaciones significativas fueron obtenidas entre la ELA anual y la SST en la región Pacífico. Se propone que la variabilidad de la SST del océano Pacífico fue el principal modulador de los cambios temporales de la ELA en los AM durante A.D 1500 - 1848.
