Ryder 2019 was an international, multidisciplinary scientific expedition to Northern Greenland aboard the Swedish Icebreaker Oden. The expedition’s primary goal was investigating the development and dynamics of the marine cryosphere and ocean conditions of the region that connects the Ryder Glacier to the southern Lincoln Sea, specifically in the Sherard Osborn Fjord and the northern Nares Strait. Secondary objectives include terrestrial research focusing on paleoclimatology and ecosystems. The land-sea connection of Ryder Glacier to the Nares Strait, is particularly of particular interest, as it’s one of the few places in the northern hemisphere where floating ice tongues exist and, due to the challenges of accessing this northern, ice-infested region, it’s never previously been explored by modern scientific means. To address our objectives, we conducted multidisciplinary scientific research over a broad range of disciplines including atmospheric chemistry and physics, biology, climatology, ecology, genomics, glaciology, oceanography, marine geology, geophysics and geochemistry. Presenter Bio Brian Calder is the Center's Associate Director. He has a Ph.D. in Electrical and Electronic Engineering, completing his thesis on Bayesian methods in Sidescan Sonar processing in 1997. Since then he has worked on a number of signal processing problems, including real-time grain size analysis, seismic processing, and wave-field modeling for shallow seismic applications. His research interests include methods for error modeling, propagation and visualization, and adaptive sonar backscatter modeling. His work has focused on developing methods for textural analysis of seafloor sonar data, as well as exploring innovative approaches to target detection and seafloor property extraction. Dr. Calder is currently focusing on statistically robust automated data cleaning approaches and tracing uncertainty in hydrographic data.
