Seasonal/Marginal Ice Zones Session at IGS Winnipeg, 18-23 August 2019.
Kia ora colleagues,
We would be delighted if you attend the IGS Symposium on Sea Ice at the Interface in Winnipeg, Canada, from August 18-23, 2019 (http://igswpg.com/),
and present in the session on Current and near future changes in seasonal/marginal ice zones. Details below. Presentations from either polar region are welcome.
Feel free to contact me if you have any questions.

Current and near future changes in seasonal/marginal ice zones
The seasonal ice zone (SIZ) is the area of ocean that extends from the permanent ice zone to the boundary where winter sea ice extent is at a maximum. At the outer margin of the SIZ is the marginal ice zone (MIZ), which is the highly dynamic,
narrow or very wide transition between the open ocean and sea ice. Depending on factors like wind direction and ocean currents, the MIZ may consist of anything from isolated, small and large ice floes drifting over a large area to a compact edge of small ice
floes pressed together in front of solid pack ice. Nowhere on Earth is climate change greater than in the highly dynamic and complex SIZ/MIZ. Ecological vulnerability in the SIZ/MIZ is also great because of high production in spring and summer, and the high
density of organisms (such as phyto- and zooplankton, fish, marine mammals and birds) in some parts of the year.
Despite its increasing size and physical, chemical and biological significance the SIZ/MIZ region is only investigated in a few Arctic and Antarctic regions, preventing adequate ecosystem understanding and sustainable management. This
session gathers polar sea-ice scientists and oceanographers that wish to contribute to an improved holistic understanding of the SIZ/MIZ region. With the practical disappearance of multiyear ice from the Arctic we in particular ask if
Antarctica can inform us about current and near future changes underway in the Arctic SIZ/MIZ?
