Generally, I am interested in how materials
from land are dispersed and accumulate in the ocean. I use sediment characteristics, environmental
measurements (including oceanographic, meteorological, and hydrologic data),
and geophysical methods like seismic-reflection tools to understand the modern
and ancient processes influencing the seabed and sedimentary record of
continental margins. This research is
important to examining the fate of pollutants and runoff, assessing carbon
sinks for climate studies, quantifying natural resources like sand for beach
nourishment, evaluating biological habitats, identifying and extracting
petroleum, and protecting our nation’s coastlines.
More specifically, here are some projects in
which I am actively involved:
Sediment dynamics on the actively deforming Waipaoa continental margin.
project, also part of the Margins
Source to Sink program, is designed to investigate the modern transport of terrestrial
sediment to and within the continental slope seaward of the Waipaoa
River, New Zealand. A research cruise
for this project occurred in February 2005 aboard R/V Kilo Moana, and another is
planned for October 2006. This research
is being conducted in collaboration with Clark Alexander (Skidaway),
Alan Orpin (National Institute for Water and Atmopheric Research, New
Zealand), Lionel Carter (National Institute for Water and
Atmosphere Research, New Zealand),
Steve Kuehl (Virginia Institute of Marine Science) and Lincoln Pratson (Duke University). A web site was created for first field
expedition, check it out: http://www.coastal.geology.ecu.edu/nz/. Ben Sumners is an MS student at ECU working
on this project.
Terrestrial sediment flux onto coral reefs of
southwestern Puerto Rico. This
research is aimed at quantifying the flux of terrestrial (land-derived)
sediment to the coral reef areas of La Parguera, Puerto Rico. The
research is being conducted in collaboration with Reide Corbett (ECU), Amos
Winter (University of Puerto Rico, Mayaguez),
Richard Appeldorn (UPRM), Francisco Pagan (UPRM) and
others. It is part of the NOAA Coral Reef
Ecosystem Studies - Caribbean program.
Katie Ryan is an MS student at ECU working on this project.
Coastal processes in North Carolina. This is a cooperative project involving researchers at
the USGS, NCGS, ECU, VIMS, and the U.
of Del. More specifically, my students and I are
involved in projects examining estuarine (1) sediment dynamics in the
Albemarle-Pamlico Estuarine System (Sophie Dillard and Kat Marciniak) and
barrier island groundwater dynamics and inlet opening (Ari
Perkins). These projects are
being conducted in collaboration with Reide Corbett, Dave Mallinson, Stan
Riggs, Steve Culver, and Mike O’Driscoll (Geology ECU).
