Wave projections for United States mainland coasts

Li Erikson, Christie Hegermiller, Patrick Barnard & Curt D Storlazzi
Coastal managers and ocean engineers rely heavily on projected average and extreme wave conditions for planning and design purposes, but when working on a local or regional scale, are faced with much uncertainty as changes in the global climate impart spatially-varying trends. Future storm conditions are likely to evolve in a fashion that is unlike past conditions and is ultimately dependent on the complicated interaction between the Earth?s atmosphere and ocean systems. Despite a lack...

Climate warming of Wisconsin lakes can be either amplified or suppressed by trends in water clarity

Kevin Christopher Rose
While climate change is rapidly warming lakes and reservoirs, warming rates can be highly variable among systems because lake characteristics can modulate atmospheric forcing. While it is known that water clarity changes can alter lake water temperatures, it is unknown if frequently observed water clarity trends are sufficient to meaningfully impact the thermal trajectories of diverse lake populations. Using process-based modeling and empirical observations, this study demonstrates that water clarity changes of about 1% per...

Forecasting tidal marsh elevation and habitat change through fusion of Earth observations and a process model

Kristin B Byrd, Lisamarie Windham-Myers, Thomas Leeuw, Bryan D Downing, James T Morris & Matthew C Ferner
Regional models of tidal marsh elevation response to sea-level rise are needed to support coastal climate change adaptation decisions, including those related to land use planning, habitat management and infrastructure design. The Marsh Equilibrium Model (MEM) is a one-dimensional mechanistic elevation model that incorporates feedbacks of organic and inorganic inputs within the tidal frame to project elevations under sea-level rise scenario. We tested the feasibility of deriving two key MEM inputs average annual suspended sediment...

A Multiscale Index of Landscape Intactness for the Western U.S.

Ian Leinwand, Natasha B. Carr & David JA Wood
Landscape intactness has been defined as a quantifiable estimate of naturalness measured on a gradient of anthropogenic influence. We developed a multiscale index of landscape intactness for the Bureau of Land Managements (BLM) landscape approach, which requires multiple scales of information to quantify the cumulative effects of land use. The multiscale index of landscape intactness represents a gradient of anthropogenic influence as represented by development levels at two analysis scales. To create the index, we...

Development of a Coastal Drought Index Using Salinity Data

Paul A. Conrads & Lisa S. Darby
A critical aspects of the uniqueness of coastal drought is the effects on salinity dynamics of creeks and rivers. The location of the freshwater-saltwater interface along the coast is an important factor in the ecological and socio-economic dynamics of coastal communities. Salinity is a critical response variable that integrates hydrologic and coastal dynamics including streamflow, precipitation, sea level, tidal cycles, winds, and tropical storms. The position of the interface determines the composition of freshwater and...
