The Deepwater Horizon (DWH) well blowout released more petroleum hydrocarbons into the marine environment than any previous U.S. oil spill (4.9 million barrels), fouling marine life, damaging deep sea and shoreline habitats and causing closures of economically valuable fisheries in the Gulf of Mexico. A suite of pollutants—liquid and gaseous petroleum compounds plus chemical dispersants—poured into ecosystems that had already been stressed by overfishing, development and global climate change. Beyond the direct effects that were captured in dramatic photographs of oiled birds in the media, it is likely that there are subtle, delayed, indirect and potentially synergistic impacts of these …
A Hybrid Background Error Covariance Model For Assimilating Glider Data Into A Coastal Ocean Model, Max Yaremchuk, Dmitri A. Nechaev, Chudong Pan
A Hybrid Background Error Covariance Model For Assimilating Glider Data Into A Coastal Ocean Model, Max Yaremchuk, Dmitri A. Nechaev, Chudong Pan
Faculty Publications
A hybrid background error covariance (BEC) model for three-dimensional variational data assimilation of glider data into the Navy Coastal Ocean Model (NCOM) is introduced. Similar to existing atmospheric hybrid BEC models, the proposed model combines low-rank ensemble covariances B(m) with the heuristic Gaussian-shaped covariances B(0) to estimate forecast error statistics. The distinctive features of the proposed BEC model are the following: (i) formulation in terms of inverse error covariances, (ii) adaptive determination of the rank m of B(m) with information criterion based on the innovation error statistics, (iii) restriction of the heuristic covariance operator B(0) to the null space of …
Soil Carbon And Material Fluxes Across The Eroding Alaska Beaufort Sea Coastline, Chien-Lu Ping, Gary J. Michaelson, Laodong Guo, M. Torre Jorgensen, Mikhail Z. Kanevskiy, Yuri L. Shur, Fugen Dou, Jingjing Liang
Soil Carbon And Material Fluxes Across The Eroding Alaska Beaufort Sea Coastline, Chien-Lu Ping, Gary J. Michaelson, Laodong Guo, M. Torre Jorgensen, Mikhail Z. Kanevskiy, Yuri L. Shur, Fugen Dou, Jingjing Liang

Carbon, nitrogen, and material fluxes were quantified at 48 sampling locations along the 1957 km coastline of the Beaufort Sea, Alaska. Landform characteristics, soil stratigraphy, cryogenic features, and ice contents were determined for each site. Erosion rates for the sites were quantified using satellite images and aerial photos, and the rates averaged across the coastline increased from 0.6 m yr-1 during circa 1950-1980 to 1.2 m yr-1 during circa 1980-2000. Soils were highly cryoturbated, and organic carbon (OC) stores ranged from 13 to 162 kg OC m-2 in banks above sea level and averaged 63 kg OC …
Circulation In The Philippine Archipelago Simulated By 1/12° And 1/25° Global Hycom And Eas Ncom, Harley E. Hurlbert, E. Joe Metzger, Janet Sprintall, Shelley Riedlinger, Robert A. Arnone, Toshiaki Shinoda, Xiaobiao Xu
Circulation In The Philippine Archipelago Simulated By 1/12° And 1/25° Global Hycom And Eas Ncom, Harley E. Hurlbert, E. Joe Metzger, Janet Sprintall, Shelley Riedlinger, Robert A. Arnone, Toshiaki Shinoda, Xiaobiao Xu
Faculty Publications
Three ocean models, 1/25 degrees global HYbrid Coordinate Ocean Model (HYCOM), 1/12 degrees global HYCOM, and East Asian Seas Navy Coastal Ocean Model (EAS NCOM) nested in global NCOM, were used to provide a global context for simulation of the circulation within the Philippine Archipelago as part of the Philippine Straits Dynamics Experiment (PhilEx). The Philippine Archipelago provides two significant secondary routes for both the Indonesian throughflow and the western boundary current of the Pacific northern tropical gyre. The deeper route enters the archipelago from the north through Mindoro Strait, after passing through Luzon Strait and the South China Sea. …
