MissDelta Teacher PD gets featured on Louisiana Considered

(Listen from 4:35-11:15 on the audio player in the below link) The Teacher PD trip to Neptune Pass, one of the fastest-changing spots on Louisiana’s coast, made its way to WWNO’s Louisiana Considered. MissDelta’s Dr. Dominique Garello and Mariam Afuwape joined the show to talk about the workshop and what it’s like trading a classroom for a research vessel.

New research finds Mississippi River losing most of its sediment before reaching Gulf

Stacey Plaisance, Tulane University Tulane University researchers are spending days at a time on the Lower Mississippi River collecting water samples by boat to better understand water and sediment flow in the region known as the Bird’s Foot Delta, the southernmost tip of the river that juts out into the Gulf. Their work involves plunging a 200-pound isokinetic sediment sampler into the river at various depths to measure river discharge, then using that information to build numerical models to test ways to save the Bird’s Foot. They are working to find out how much sediment remains in the wetlands above water versus how much exits into the deepwater Gulf.  

Tracking the sediment carried by the muddy Mississippi

New research shows that typically, less than 10% of land-building alluvium reaches the Bird’s Foot Delta region, the southernmost reach of the river, where it meets the Gulf. By Delaney Dryfoos for The Lens.

Saving the Mississippi Delta 

When Samuel Bentley, professor and Billy and Ann Harrison Chair in Sedimentary Geology, made the transition from an administrative role to re-engage in research, he did so on a grand scale.
