In this study, we combine remote sensing, in situ and model-derived datasets from 1966 to 2014 to calculate the mass-balance components of Kronebreen, a fast-flowing tidewater glacier in Svalbard. For the well-surveyed period 2009–2014, we are able

Parameterizing deep water percolation improves subsurface temperature simulations by a multilayer firn model

Autor: Marchenko, S., van Pelt, W.J.J., Claremar, B., Machguth, H., Reijmer, C.H., Pettersson, R., Pohjola, V.A., Sub Dynamics Meteorology, Marine and Atmospheric Research

Publikováno v: Frontiers in Earth Science, Cryosphere, 5, 1. Frontiers Media

Deep preferential percolation of melt water in snow and firn brings water lower along the vertical profile than a laterally homogeneous wetting front. This widely recognized process is an important source of uncertainty in simulations of subsurface t

An iterative inverse method to estimate basal topography and initialize ice flow models

Autor: van Pelt, W.J.J., Oerlemans, J., Reijmer, C.H., Pettersson, R., Pohjola, V.A., Isaksson, E., Divine, D., Marine and Atmospheric Research, Sub Dynamics Meteorology

We present and evaluate an inverse approach to reconstruct two-dimensional fields of bedrock topography and simultaneously initialize an ice flow model. The inverse method involves an iterative procedure in which an ice dynamical model (PISM) is run

Modelling the dynamics and boundary processes of Svalbard glaciers

Autor: van Pelt, W.J.J.

The focus of this thesis is on improving our understanding of surface and basal processes in the context of glaciers in Svalbard. At the surface, interactions with the atmosphere and underlying snow determine the surface mass balance. A coupled model

Numerical simulations of cyclic behaviour in the Parallel Ice Sheet Model (PISM)

Autor: van Pelt, W.J.J., Oerlemans, J.

Numerical experiments are conducted on a synthetic topography with a three-dimensional thermomechanically coupled ice-sheet model, the Parallel Ice Sheet Model (PISM). Within the model, combined stress balances are connected to evolving thermodynamic
