Ensemble-Based Data Assimilation for Estimation of River Depths

Creator:: Wilson, Greg and Özkan-Haller, H. Tuba
Abstract:: A method is presented for estimating bathymetry in a river, based on observations of depth-averaged velocity during steady flow. The estimator minimizes a cost function that combines known information in the form of a prior estimate and measured data (including measurement noise). State augmentation is used to relate the measured...

Satellite views of Pacific chlorophyll variability: comparisons to physical variability, local versus nonlocal influences and links to climate indices

Creator:: Thomas, Andrew C., Strub, P. Ted, Weatherbee, Ryan A., and James, Corinne
Abstract:: Concurrent satellite-measured chlorophyll (CHL), sea surface temperature (SST), sea level anomaly (SLA) and model-derived wind vectors from the 13+ year SeaWiFS period September 1997 – December 2010 quantify time and space patterns of phytoplankton variability and its links to physical forcing in the Pacific Ocean. The CHL fields are a...

Ocean Mixing by Kelvin-Helmholtz Instability

Creator:: Smyth, William D. and Moum, James N.
Abstract:: Kelvin-Helmholtz (KH) instability, characterized by the distinctive finite-amplitude billows it generates, is an important mechanism in the development of turbulence in the stratified interior of the ocean. In particular, it is often assumed that the onset of turbulence in internal waves begins in this way. Clear recognition of the importance...

The manganese and iron shuttle in a modern euxinic basin and implications for molybdenum cycling at euxinic ocean margins

Creator:: Scholz, Florian, McManus, James, and Sommer, Stefan
Abstract:: A meaningful application of Mo as a paleo-redox proxy requires an understanding of Mo cycling in modern reducing environments. Stagnant euxinic basins such as the Black Sea are generally regarded as model systems for understanding euxinic systems during early Earth history. However, drawing direct parallels between the Black Sea and...

Air-Sea Interactions from Westerly Wind Bursts During the November 2011 MJO in the Indian Ocean

Creator:: Moum, James N., de Szoeke, Simon P., Smyth, William D., Edson, James B., DeWitt, H. Langley, Moulin, Aurélie J., Thompson, Elizabeth J., Zappa, Christopher J., Rutledge, Steven A., Johnson, Richard H., and Fairall, Christopher W.
Abstract:: The life cycles of three Madden–Julian oscillation (MJO) events were observed over the Indian Ocean as part of the Dynamics of the MJO (DYNAMO) experiment. During November 2011 near 0°, 80°E, the site of the research vessel Roger Revelle, the authors observed intense multiscale interactions within an MJO convective envelope,...

Community Responses to Climate-Related Variability and Disease: The Critical Importance of Long-Term Research

Creator:: Menge, Bruce A., Caselle, Jennifer E., Barth, John A., Blanchette, Carol A., Carr, Mark H., Chan, Francis, Gravem, Sarah, Gouhier, Tarik C., Lubchenco, Jane, McManus, Margaret A., Milligan, Kristen, Novak, Mark, Raimondi, Peter T., Washburn, Libe, and White, J. Wilson
Abstract:: A major goal of the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) has been to understand the impacts of climate change and variability on the coastal ecosystems of the inner shelf of the California Current Large Marine System in particular, and other marine and even nonmarine systems more generally....

Planning for Change: Assessing the Potential Role of Marine Protected Areas and Fisheries Management Approaches for Resilience Management in a Changing Ocean

Creator:: Kroeker, Kristy J., Carr, Mark H., Raimondi, Peter T., Caselle, Jennifer E., Washburn, Libe, Palumbi, Stephen R., Barth, John A., Chan, Francis, Menge, Bruce A., Milligan, Kristen, Novak, Mark, and White, J. Wilson
Abstract:: Despite progressive policies and continued advances in ocean management, numerous shifts associated with global changes have been observed in marine ecosystems in recent years, including warming, ocean acidification, and deoxygenation. As global change accelerates, science is needed to inform evidence-based management strategies for continued ecosystem services. Resilience management, in which...

Abstract:: Twenty years ago, the creation of a new scientific program, the Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO), funded by the Packard Foundation, provided the opportunity to integrate—from the outset—research, monitoring, and outreach to the public, policymakers, and managers. PISCO’s outreach efforts were initially focused primarily on sharing scientific...

A field comparison of multiple techniques to quantify groundwater–surface-water interactions

Creator:: González-Pinzón, Ricardo, Ward, Adam S., Hatch, Christine E., Wlostowski, Adam N., Singha, Kamini, Gooseff, Michael N., Haggerty, Roy, Harvey, Judson W., Cirpka, Olaf A., and Brock, James T.
Abstract:: Groundwater–surface-water (GW-SW) interactions in streams are difficult to quantify because of heterogeneity in hydraulic and reactive processes across a range of spatial and temporal scales. The challenge of quantifying these interactions has led to the development of several techniques, from centimeter-scale probes to whole-system tracers, including chemical, thermal, and electrical...

Early retreat of the Alaska Peninsula Glacier Complex and the implications for coastal migrations of First Americans

Creator:: Misarti, Nicole, Finney, Bruce P., Jordan, James W., Maschner, Herbert D. G., Addison, Jason A., Shapley, Mark D., Krumhardt, Andrea, and Beget, James E.
Abstract:: The debate over a coastal migration route for the First Americans revolves around two major points: seafaring technology, and a viable landscape and resource base. Three lake cores from Sanak Island in the western Gulf of Alaska yield the first radiocarbon ages from the continental shelf of the Northeast Pacific...
