WP2 - Evolution and Dynamics of the glacial cap and outlet glaciers in Greenland

WP2 - Evolution and Dynamics of the glacial cap and outlet glaciers in Greenland

Specific activities
Greenland outlet glaciers monitoring observed by the analysis of seismic data collected through the regional seismic network Greenland Ice Sheet Monitoring Network (GLISN) trying also to find out correspondence in the glacier tongue evolution derived by the observation of satellite images. By studying the long period seismic signals at stations located at the mouth of large fjords (e.g. ILULI, NUUG, KULLO), we identify major calving events through the detection of the ground flexure in response to seiche waves generated by iceberg detachments. For the time spanning the period between 2010-2014, we fill out calving-events catalogue that can be useful for the estimation of spatial and temporal variations in volume of ice loss at major active fronts in Greenland. Seismic data were inverted using Radio Echo Sounding (RES) reliable 3D models of the glacier outlet areas trying to discriminate the physical condition of the ice-bedrock interfaces.

Institution: INGV - OGS

Expected results
    - Maps of wet/dry bedrock-ice interface in some areas of Greenland.
    - Catalogue of the most significant calving events for some of major glaciers.
    - Theoretical model of the seismic signal produced by the iceberg-fjord interaction.

ARctic: present Climatic change and pAst extreme events (ARCA)

Download publications ARctic: present Climatic change and pAst extreme events in PDF format

ARCA aims to develop a conceptual model on the mechanism(s) behind the release of large volumes of cold and fresh water from melting of ice caps, investigating this complex system from both paleoclimatic and modern air-sea-ice interaction process point of view. ARCA fits well within the Italian Strategy for Arctic (Read more).

Activities of ARCA project include:

  • support to an international scientific drilling campaign (CORIBAR) and analyses of resulting data,
  • intensive campaigns aimed to study the energy balance at the surface interaction processes and air-sea-ice (along the edge of the tidewater glaciers that overlook the Kongsfjorden),
  • the acquisition / data sharing for monitoring the dynamics of large outlet glaciers of Greenland.


Qualifying elements of the proposed activity will be:

  • the development and testing of new technologies aimed at improving process investigation at the interfaces of the different system components, in particular hydrosphere-atmosphere and hydrosphere-cryosphere,
  • the implementation of an ICT distributed structure, based on thematic and multidisciplinary nodes and brokering approach concepts, for managing, use and dissemination of data to the scientific community and beyond,
  • the upgrade of existing observational platforms, with the aim to (1) exploit efforts made by the groups partecipating to ARCA in the same areas and measuements sites since the International Polar Year (IPY) operational period (2007-2009), and (2) leave a significant legacy for future activities.
