Decline in the extent and thickness of Arctic sea ice is an active area of scientific effort and one with significant implications for ecosystems and communities.. Forecasting for seasonal timescales (i.e., the summer and into fall) is of particular interest to many stakeholders.. Michael . Dutter. and Todd . Kluber. NOAA/National Weather Service Marquette, . MI. 2014 Great Lakes Operational Meteorology Workshop – Ann Arbor, MI. Despite Lake Superior being completely (or nearly completely) ice covered for much of Feb-April 2014, lake effect bands were still occasionally observed. Some of these proved to be relatively significant.. History of Sea Level Rise in Florida. 120,000 years ago 18,000 years ago Today. + 6 meters - 120 meters . Causes of Sea Level Rise.

Ice Hockey What is Ice Hockey Ice Hockey is a game played In the Olympics and for a weekend sport. Ice hockey is a very competitive because it is an Olympic sport so more people play ice hockey more often. Objective. The Los Alamos Sea Ice model has a number of input parameters for which accurate values are not always well established. . We conduct a variance-based sensitivity analysis . of hemispheric sea ice properties to 39 input parameters. The method accounts for non-linear and non-additive effects in the model.. Julia R.
