Scientific objectives
The main goal has been to investigate and
quantify the present and the past 800 years
of climate by means of shallow and medium
depth ice core records from Svalbard
20th century
The last 600 years
Main conclusions up to now
 With careful site selection and with
detailed sampling Svalbard ice cores
can provide important information on
both local and regional climate
variability in the Arctic

The main objectives
 to obtain a reliable estimate of the total ice volume
stored in Svalbard;
 to estimate the recent past climate changes and
mass balance rates of Svalbard;
 to improve the process understanding related to
mass balance and ice dynamics;
 to model the expected response in surface mass
balance and calving flux rate under different
scenarios of climate change.
 The overriding goal is the knowledge and the
quantitative depiction of the Svalbard glacier
evolution model under the climate change condition.
