Ice Tank Investigations of the Microstructure of Artificial
Sea Ice Grown under different Boundary Conditions during INTERICE II A
short overview about the EU-LSF INTERICE II project conducted in the Arctic
Environmental Test Basin of the Hamburg Ship Model Basin (HSVA) in Hamburg,
Germany, is given. The project team investigated physical, bio-geochemical,
and sedimentological aspects of sea ice growth processes. Some features
from the microstructure studies are presented. These include crystal and
pore space data from a freeze-melt-refreeze cycle and from ice grown at
different under-ice currents, and temperature measurements at the progressing
ice water interface. The feasibility of large ice tank studies is discussed.
