Alfredo Aretxabaleta , PhD
Alfredo's (he/him/his), research mainly focuses in processes controlling water level in coastal environments including tidal effects, storm events, and sea level rise. Another important focus is the investigation of the problems related to sediment transport, especially during storm events, that can affect the redistribution of sediment.
I have a B.S. degree in Marine Sciences (1998) from the Universidad de Las Palmas de Gran Canaria (ULPGC) and a Ph.D. in Marine Sciences (Physical Oceanography) from UNC Chapel Hill (2005). I worked as a post-doctoral research fellow at the Department of Marine Sciences at UNC Chapel Hill, at the Woods Hole Oceanographic Institution (AOPE), and at the Instituto de Ciencias del Mar - CSIC in Barcelona, Spain. I worked as a scientific programmer contractor at U.S. Geological Survey Woods Hole Coastal and Marine Science Center (WHCMSC) until 2016. Now, I am an oceanographer at the WHCMSC.

Making USGS/NOAA Total Water Level and Coastal Change Forecast data accessible through user-friendly interfaces
The Total Water Level and Coastal Change Forecast delivers 6-day forecasts of hourly water levels and the probability of waves impacting dunes along 5000 km of sandy coasts along the Atlantic and Gulf of Mexico and will soon expand to the Pacific. These forecasts provide needed information to local governments and federal partners and are used by the USGS to place sensors before a storm. The forec
COAWST: A Coupled-Ocean-Atmosphere-Wave-Sediment Transport Modeling System
Understanding the processes responsible for coastal change is important for managing both our natural and economic coastal resources. Storms are one of the primary driving forces causing coastal change from a coupling of wave- and wind-driven flows. To better understand storm impacts and their effects on our coastlines, there is an international need to better predict storm paths and intensities...
Coastal System Change at Fire Island, New York
Fire Island is a 50-km long barrier island along the south shore of Long Island, New York. The island is comprised of seventeen year-round communities; federal, state, and county parks; and supports distinct ecosystems alongside areas of economic and cultural value. In addition to providing resources to its residents, the barrier island also protects the heavily-populated mainland from storm waves...
Back-barrier and Estuarine - Coastal System Change at Fire Island, New York
Regional-scale modeling forecasts how atmospheric forcing and oceanographic circulation influence estuarine circulation and water levels, sediment transport, and wetland change.
Estuarine Processes, Hazards, and Ecosystems
Estuarine processes, hazards, and ecosystems describes several interdisciplinary projects that aim to quantify and understand estuarine processes through observations and numerical modeling. Both the spatial and temporal scales of these mechanisms are important, and therefore require modern instrumentation and state-of-the-art hydrodynamic models. These projects are led from the U.S. Geological...
Coastal Model Applications and Field Measurements
Numerical models are used by scientists, engineers, coastal managers, and the public to understand and predict processes in the coastal ocean. This project supports the development and application of open-source coastal models and has several objectives: 1) improve the code of numerical sediment-transport models by implementing new or improved algorithms; 2) obtain measurements of coastal ocean...
Estuarine Processes Coastal Hazards
Extreme tides and coastal storms transfer high water levels to estuaries through natural and managed entrances. The size of the transfer depends on the duration of the event and the geomorphology of the estuary. We use observational data and modeling scenarios to understand and spatially map this transfer at our study sites.
Estuarine Processes Model Development
We are developing new routines within the COAWST model framework to represent coupled bio-physical processes in estuarine and coastal regions. These include routines for marsh vulnerability to waves, estuarine biogeochemistry, and feedbacks between aquatic vegetation and hydrodynamics.
