Donya P Frank-Gilchrist, Ph.D.

Donya’s research focuses on understanding how waves and currents mobilize sand and other objects on the seafloor. 

Her projects involve a wide range of scales from investigating incipient motion of individual sand grains up to modeling the evolution of barrier islands in response to tropical storms. In addition, she assesses the vulnerabilities of underrepresented communities to coastal hazards through stakeholder engagement.

Laboratory Observations of Variable Size and Shape Particles: Artificial Sand and Oil Agglomerates

Following marine oil spills, weathered oil can mix with sediment in the surf zone and settle to the seafloor to form mats up to hundreds of meters long. Wave action fragments these mats into 1 to 10 cm diameter sand and oil agglomerates (SOAs). SOAs can persist for years, becoming buried in or exhumed from the seafloor and/or transported cross-shore and alongshore (Dalyander and others, 2015). The
