Introduction
My PhD project concerns the study of the ablation areas in Antarctica, relevant for surface mass balance (i.e. glazed snow and blue ice), by mapping them and analyzing their trends in time.

Megadunes are peculiar snow dune fields known to be present only on the East Antarctic plateau and other planets (Mars and Pluto). Antarctic megadunes are climatically important because their leeward flanks are characterized by glazed surfaces, a particular morphogenetic state of snow which makes these zones ablation areas, as their surface mass ba...
Dissemination and communication of landscape features have been for long time an important goal for explorers and travellers. The description of landforms and of the processes that determine them now assume a key role in geoeducation. From this point of view, outdoor experiences represent a great opportunity to improve the scientific knowledge of s...
The albedo is a fundamental component of the processes that govern the energy budget, and particularly important in the context of climate change. However, a satellite-based high-resolution (30 m) albedo product which can be used in the polar regions up to 82.5° latitude during the summer seasons is lacking. To cover this gap, in this study we calc...

Blue ice areas (BIAs) are relevant ablation surfaces present on the Antarctic continent, mainly located in proximity of the coast or mountainous zones, in sloping areas. Featuring negative values of surface mass balance, in a continent where this parameter is averagely positive, their study gains of importance, in particular regarding their evoluti...
The aim of the study is to analyse the surface albedo of the Ant-arctica and investigate eventual signals of variations in space and time between summer 2000/2001 and 2011/2012 by means of the GLASS albedo product. We followed a step-by-step procedure from micro- to macro-scale. At first, we analysed 95 glaciers around the continent, and we found l...

Project (1)
The project concerns the study of those areas in Antarctica that behave differently from the rest of the ice sheet (i.e. wind crust and blue ice zones) and therefore relevant for surface mass balance studies. Thus, the main objectives are the mapping of these areas and the analysis of their spatial and temporal trends by means of remote sensing observations (e.g. Landsat, MODIS, Sentinel-2 imagery).
