The Sea Ice Prediction Network (SIPN) announces an open webinar entitled
"Challenges and Best Practices: Sea Ice Thickness Distribution as a
Rosetta Stone for Cross-Scale Communication." This event is scheduled
for Tuesday, 22 March 2016 from 9:00 a.m. to 10:00 a.m. AKDT.
This webinar is designed for the sea ice research community and others
interested in learning about issues related to estimating sea ice
thickness across many scales. While this is an open event, attendees
should be aware that the discussions will largely be of a technical
nature. The speaker will be Cathleen Geiger, University of Delaware.
Sea ice is a unique geophysical material capable of spanning a large
range of horizontal length scales while at the same time only varying by
meters in vertical extent. As example, a sea ice crack can be less than
a meter-wide in one horizontal direction and stretch across the Arctic
basin (thousands of kilometers) in the other direction.
This presentation will include discussion on the consistency of sea ice
thickness distributions across different horizontal length scales,
specifically the issue of measurement accuracy and some of the
challenges related to estimating sea ice thickness across many length
scales; offer insight into the general phenomenon of "up-scaling" by
considering scaling relationships as a form of communication,
specifically the communication of information between scales; and some
new best practices illustrated with a simple heuristic model and some
small case studies.
The webinar is scheduled for 9:00 a.m. to 10:00 a.m. AKDT (10:00 a.m.to
11:00 a.m. PDT, 11:00 a.m. to 12:00 p.m. MDT, 12:00-1:00 p.m. CDT, and
1:00-2:00 p.m. EDT) on Tuesday, 22 March 2016.
More details including registration instructions, will be announced
closer to the event. The webinar will be archived and available online
after the event.
