Active Scattering in Sea Ice for Measuring Internal Properties

Sea ice is filled with small brine pockets because the salt is rejected by the crystal lattice during the freezing process. These brine pockets have a significant influence on several aspects of sea ice, including its bearing capacity, the remote sensing of it, as well as the amount of solar ener...

Glacier Surface Topography Mapping for Satellite Radar Altimetry

Radar altimeter satellite missions such as CryoSat-2, Sentinel-3, and the upcoming CRISTAL are widely used for monitoring key parameters of land ice such as glacier mass balance change. The uncertainties of the data from these satellites produced over more complex ice caps and glaciers are poorly...

Fjord Interaction Network in Svalbard

Arctic near-surface temperatures have warmed nearly four times faster than the rest of the globe since 1979 and Svalbard is located at a hotspot for this warming. Local impacts of this warming are strongly evident in the West Spitsbergen fjord systems, such as Isfjorden and Kongsfjorden, which ar...

Tracing warm Atlantic Water in Tempelfjorden, Svalbard - RiS ID 12116

This project uses a combination of high-resolution modelling and observations in Tempelfjorden, a side fjord of Isfjorden with 2 marine-terminating glaciers (MTGs), to investigate under which conditions Atlantic Water (AW) enters the fjord, how it affects MTGs and how it will change with an enhan...

Investigating the active layer ice content and resulting thaw dynamics in Adventdalen. RiS ID 12143.

This M.Sc. thesis project aims at quantifying how well remotely sensed ground deformation captures the ice/water content of the active layer in different landforms/ground conditions. It will further be investigated if assimilating the remotely sensed ground deformation into the permafrost model C...

Investigation of the spatio-temporal variability of winds in Isfjorden, RiS 11609

Vertical wind profiles will be collected utilizing a light detection and ranging (LIDAR) instrument. The LIDAR will be mounted onboard different research and commercial vessels sailing in Isfjorden. This will allow to investigate the temporal and spatial variability of winds within the marine bou...

Channelling in Adventdalen, RiS ID 11606

This study investigates the wind climate in Adventdalen and Adventfjorden by identifying connections between the above-valley (large-scale) wind and the within-valley wind, both on a climatological scale and for detailed case studies. For the climatological approach, the combined wind density dis...

Data collection for validating the AROME-Arctic Weather Model. RiS ID: 11430

In this project we will collect wind data with a light detection and ranging (LIDAR) instrument for validation of the AROME-Arctic numerical weather prediction (NWP). AROME-Arctic has been run operationally for a region covering the European Arctic, including Svalbard, since late 2015 by the Norw...

Validation and Application of Novel Wind Estimation Techniques with UAVs in the Arctic

This project aims to develop the novel application of rotary wing unmanned aerial vehicles (UAVs) for wind speed and direction estimation in the Arctic. The method relies on using the drone’s inertial measurements (pitch, roll, yaw angles & thrust) in a GPS-hold mode to estimate wind. The method ...

Kongsvegen Glacier Surge Dynamics RIS 10933

The aim of this project is to collect data to test a new theory of glacier surges - enthalpy cycling theory. The theory predicts that surges occur where frictional heating creates heat and meltwater (enthalpy) faster than it can be lost. This prediction will be tested for Kongsvegen, a glacier kn...

Flux seasonality, drivers and wind-speed parameterisation of the gas transfer velocity in an Arctic fjord: Sea-air CO2 exchange in Isfjorden

In this study we want to present the first direct (Eddy Covariance method) air-sea CO2 exchange time series from an arctic fjord in Svalbard. Direct continuous measurements of air-sea CO2 exchange are the key to understand how the flux varies in time and space. In addition to land-based flux me...

Seasonal variability in glacial meltwater and sea-air CO2 fluxes in Tempelfjorden, Svalbard (RiS ID 10662)

Observations of retreating glaciers point to the need of understanding how glaciers affect the physical and biogeochemical processes that influence the marine carbon cycle. Tempelfjorden is influenced by a tidewater glacier that has undergone dramatic changes recently. This is a unique opportunit...
