CLIMATOLOGY |

Professional interests focus on the simple theme of “getting a better look at ice, especially sea ice.” At the human scale, sea ice looks like a vast frozen white desert punctuated by sharp ridges and open-water leads and polynyas. With the recent advances in remote sensing, computer technology, and telecommunications, it is now possible to “look” at the ice at spatial scales beyond the human vision. Furthermore, the speed of modern technology affords us the luxury of replaying events at temporal scales many times faster than they occur. This gives us the opportunity to assess and analyze events in the past in order to better understand the present and prepare ourselves for the future. Long-term goals include taking advantage use of the scales beyond the range of human perception to improve navigation in polar seas, better prepare humanity for survival in these regions, and assess the interaction and impact of sea ice on our world. Several ongoing research projects focus on research and development ideas that both support the discovery elements of science but also advance the development of operational tools necessary to facilitate scientific discovery. |

Brian Hanson - Graphics and posters related to research on Storglaciären, calving glaciers, vector correlation, snowcover modeling, glacier forelands in the Cascades.
Storglaciären flows out of two cirques on the flanks of Kebnekaise (visible peak in the upper row) at 68°N in Sweden. Its mass balance has been monitored since the 1940s. The area has been visited regularly for a much longer period, so a few old photographs are available to demonstrate long-term environmental change. This glacier is accessible from Tarfala Research Station, and has been the site of a number of field studies, including attempts to measure till deformation and studies of flow speed in relation to internal hydrology. Other Storglaciären pictures. |
Dan Leathers - The DEOS Mission
The Delaware Environmental Observing System (DEOS) is a tool for decision makers involved with emergency management, natural resource monitoring, transportation, and other activities throughout the State of Delaware. DEOS also provides both State agencies and the citizens of Delaware with immediate information as to environmental conditions in and around the State. |

Delphis Levia - Some ongoing research projects
Professor Levia is a forest hydrologist with research expertise in biosphere-climate interactions, canopy-snow interactions, and forest biogeochemistry. Current research projects include a NSF-funded study examining DOC and DON cycling in northeastern Maryland, a UDRF-funded hydrology study examining stemflow yield at high temporal resolutions, and an incipient NSF-funded research collaboration examining canopy-snowpack interactions in relation to the avalanche hazard in concert with colleagues at the Swiss Federal Snow and Avalanche Institute in Davos, Switzerland. |

Cort Willmott - Global Climate Analysis
Our main interest is in producing high-resolution climate fields over spatially extensive regions, primarily from historical (weather-station) records, to help us understand and document large-scale climate patterns and climatic change. Seasonal and interannual scales of temporal variability are of particular concern. Our gridded climate fields also have been used for initializing and verifying global climate models (GCMs), as well as for corroborating satellite-derived estimates of climate variables. In addition, we are working to improve our spatial interpolation algorithms, as well as statistical approaches to accuracy assessment. |
