Coastal Climate Impacts

The impacts of climate change and sea-level rise around the Pacific and Arctic Oceans can vary tremendously. Thus far the vast majority of national and international impact assessments and models of coastal climate change have focused on low-relief coastlines that are not near seismically active zones. Furthermore, the degree to which extreme waves and wind will add further stress to coastal...

2012 SPARROW Models for the Northeast: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow

The 2012 SPAtially Referenced Regression On Watershed attributes (SPARROW) Models measure the damaging contaminants of phosphorus, nitrogen, and suspended sediment in streamflow throughout the Northeast United States. Through various types of watershed management practices, loads of nutrients and suspended sediment are significantly reduced within the stream network in impounded reaches, and...
