"Palaeo-ice flow, retreat and meltwater behaviour in the Gulf of Bothnia."

Dear all,

We are happy to announce the first paleoseminar of this semester!

Time:  Friday 26th September at 11:15 - 12:00
Place: Palstrat Salen second floor at GEO

Dr. Sarah Greenwood, Stockholm University

"Palaeo-ice flow, retreat and meltwater behaviour in the Gulf of
Bothnia."

  The Gulf of Bothnia has variably played host to the main ice divide
of the Fennoscandian ice sheet, ice stream onset, trunk and retreat
zones, marine ice sheet decay into the large proglacial Baltic Ice
Lake, and the subsequent development of an inland marine basin. It is
likely to have acted as both source and depocentre for the delivery of
ice, water and sediment in both subglacial and ice-marginal domains.
These domains and dynamics have been largely inferred from
terrestrial, peripheral evidence. the submerged terrain and its
geological archives are virtually unknown. In recent years large
swaths of high resolution multibeam echo-sounding data from the Gulf
of Bothnia have been collected for the Swedish Maritime
Administration. These data reveal, with unprecedented clarity, glacial
landforms associated with the flow and retreat of ice and the
glaciohydrological regimes in this basin. In this talk I will present
and discuss evidence for varying ice flow patterns and behaviour, and
the roles of mass melting and iceberg calving in governing the
dynamics of ice retreat.

We hope to see many of you there!

Cheers,
Kristian
