Ongoing and Past Research Projects

1. NOAA - MMS co-funded Northern Gulf of Mexico Ecosystem Research Program (NGOMEX) , which is examining how physical, geochemical, and sedimentological processes impact hypoxia in the Gulf of Mexico.

Developing a three-dimensional sediment transport model (ROMS) for the Texas / Louisiana coast and interfacing the sediment calculations with a biogeochemical model.
Mechanisms Controlling Hypoxia (MCH)
Model Result Link

2. NSF Margins S2S Program - Gulf of Papua

XRD mineral analysis on sediment provenances and redistribution process in the Gulf of Papua

3. ONR, Yangtze River and East China Sea

Spatial and temporal variations on the water and sediment discharge from the Yangtze River to the inner shelf of East China Sea, as well as structure and formation of the Yangtze-derived Holocene Clinoform in the Inner Shelf.
