Abstract

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.

Larry Mayer is a Professor and the Director of the Center for Coastal and Ocean Mapping at the University of New Hampshire. He graduated magna cum laude with an Honors degree in Geology from the University of Rhode Island in 1973 and received a Ph.D. from the Scripps Institution of Oceanography in Marine Geophysics in 1979. At Scripps, he worked with the Marine Physical Laboratory's Deep-Tow Geophysical package, applying this sophisticated acoustic sensor to problems of deep-sea mapping and the history of climate. After being selected as an astronaut candidate finalist for NASA's first class of mission specialists, Larry went on to a Post-Doc at the School of Oceanography at the University of Rhode Island where he worked on the early development of the Chirp Sonar and problems of deep-sea sediment transport and paleoceanography. In 1982, he became an Assistant Professor in the Dept. of Oceanography at Dalhousie University and in 1991 moved to the University of New Brunswick to take up the NSERC Industrial Research Chair in Ocean Mapping. In 2000 Larry became the founding director of the Center for Coastal and Ocean Mapping at the University of New Hampshire and the co-director of the NOAA/UNH Joint Hydrographic Center.

Elizabeth Weidner is a jointly appointed PhD Student in Oceanography at the University of New Hampshire and Stockholm University. She graduated from the University of Washington in 2012 with a B.S. in Oceanography. Before coming to CCOM/JHC, she worked as a geophysicist for C&C Technologies. In May of 2018, she received her Master's in Earth Science: Ocean Mapping from the University of New Hampshire with a thesis titled: "A wideband acoustic method for direct assessment of bubble-mediated methane flux." Her current research is focused on the broadband acoustic discrimination and characterization of mixing phenomenon in the water column.
