abstract = {Global sea level has been persistently rising throughout
the 20th century and is expected to continue this
development in the future. Glaciers and ice caps outside the
large ice shields of Greenland and Antarctica have been
identified as important contributors to sea-level rise.
However, to yield any model-based quantification of this
development, the climate-related surface mass balance of
these ice masses is a crucial factor to be known. Two
particularly influencing regions regarding global sea-level
rise are Patagonia and the Arctic islands and archipelagos.
This thesis deals with modelling and observation of glacier
surface mass balances in these regions. Two ice caps form
the regional case-study sites: Gran Campo Nevado located in
southernmost Patagonia close to the Strait of Magellan and
Vestfonna located in the northern Svalbard archipelago on
the island Nordaustlandet. As it is the case for most remote
regions of the world, data availability regarding these ice
caps is insufficient for sophisticated, physically-based,
dynamic modelling of glacier mass balance. Hence, feasible
modelling methods of low complexity are employed to cope
with the limitations regarding input data quantity and
quality. The modelling approaches are based on the well
established temperature-index method and are enhanced and
further developed where ever necessary. First calculations
of the surface mass balance of Gran Campo Nevado and
Vestfonna are presented in individual studies. For Gran
Campo Nevado also long-term past and future glacier
evolution and climate sensitivity characteristics are
analysed. In doing so, this thesis contributes to improve
the knowledge about mass balance and potential contribution
to sea-level rise of Patagonian and Arctic glaciers.
Furthermore, it presents a set of enhancements and newly
introduced approaches regarding glacier mass-balance
modelling. These novelties are especially aimed at
contributing to fulfilling the need of development of simple
but nevertheless reliable glacier models that can be used to
estimate the evolution of glaciers and ice caps in difficult
to access, remote areas of the world. This finally serves to
facilitate a more complete estimate of glacier induced
sea-level rise.},
