Sediment echosounding data files from the Amundsen Sea

The flow of ice streams, which account for most discharge from large ice sheets, is controlled by processes operating at their bed. Data from modern ice stream beds are difficult to obtain, but where ice advanced onto continental shelves during glacial periods extensive areas of the former bed can be imaged using modern swath sonar tools. We present new multibeam swath bathymetry data analyzed alongside sparse pre-existing data from the Amundsen Sea Embayment. The compilation is the most extensive, continuous area of multibeam data coverage yet obtained on the inner continental shelf of Antarctica. The data reveal streamlined subglacial bedforms that define a zone of paleo-ice stream convergence but, in contrast to previous models, do not show a simple down-flow progression of bedform types along paleo-ice stream troughs. We interpret high spatial variability of bedforms as indicating a complex mechanical and hydrodynamic regime at the former ice stream beds, consistent with observations from some modern ice streams. We conclude that care must be taken when using bedforms to infer paleo-ice stream velocities.

Stream monitoring manual /

Introduction: Illinois RiverWatch is a volunteer stream monitoring program coordinated by the Illinois Department of Natural Resources (DNR). Through RiverWatch Illinois citizens are trained as Citizen Scientists to conduct biological monitoring of the state's rivers and streams in order to identify long-term trends in stream health. RiverWatch provides citizen volunteers a hands-on opportunity to learn about stream ecology and the condition of Illinois streams, while helping scientists monitor stream conditions across the state.
