Lab News
August 11, 2023. Robert Feder and Mercedes Pinzon both graduated with their MS degrees today. Their
research will help Louisiana manage the nearly 3 billion dollar coastal restoration
river diversion operations. Mercedes has relocated to Orlando, FL where she has joined
the laboratory of Dr. Lisa Chambers in pursuit of a Ph.D. at the University of Central
Florida. Robert will be moving soon to Washington DC where he will being a a year
paid Knauss Fellowship funded by NOAA working with Policymakers on Environmental Issues.
They will be missed but we are excited for their new adventures ahead !
July 18, 2023. Dr. White was in London again assisting with the Study Abroad Program where undergraduates
from LSU spend a month learning about Urban Sustainability and Water Resources. We
visited Cranfield University which does research on improving wastewater performance
and is working on the "airport of the future" among other attractions including "The
living lab" and the National Soil Survey archive for the UK.
June 22, 2023 Robert sucessfully defended his Master's thesis research entitled "Effects of coastal
freshening on porewater chemistry and nutrient availability in brackish marsh soils:
Implications for biogeochemical resilience in Barataria Basin, LA". Next up for Robert
is working on submitting his research papers and graduation on August 11, 2023. Robert
has received word that he has received a Knauss fellowship from NOAA in Washington
DC.
June 16, 2023 Mercedes successfully defended her Master's thesis research entitled "Impact of Sediment
Diversion for Coastal Restoration on Nitrogen and Phosphorus Biogeochemical Cycling
in Coastal Louisiana, USA". Next up for Mercedes is working on submitting her research
papers and graduation on August 11, 2023. Mercedes will be joining Dr. Lisa Chambers
laboratory at the University of Central Florida to pursue a Ph.D. after graduation.
June 13-15, 2023 Drs. White and Hiatt were invited to attend a DOE on site review at the Smithsonian
Environmental Research Center in Maryland. The site has impressive real time data
collections for forests and coastal wetlands.

June 1, 2023 Both Mercedes and Robert presented oral presentations and poster presentations at
the State of the Coast Conference in New Orleans, LA outlining their research importance
to the Louisiana Coastal Master Plan. The college wrote a story about their research
located HERE
March 26, 2023 The WABL was out on the Lake Pontchartrain Estuary collecting cores for James' and
Kate's undergraduate research project. Lee came along to help out piston coring and
to get a first hand look at his study site.
March 16-18, 2023 Both DOCS Adjunct Faculty Member Dr. Jacob Berkowitz and Dr. White hosted a Hydric Soils Identification and Delineation Workshop at LSU for consultants and graduate students. Here we are down by the Mississippi River levee identifying soils.
February 16, 2023 Dr. White's Wetlands and Water Quality (Service-Learning) class visited Iberville
Math, Science, Arts Academy to talk with the high school students about succeeding
in college and different STEM jobs. These high school students will mostly be first-generation
college students and this was a great opporunity for the LSU students (Team Duckweed
in the picture on the left) to share what they have learned thus far in their academic
journey. This was the 9th out of 10 years (no visit in pandemic year) that we have
visited with the high school students.
February 12, 2023 While the rest of the world was preparing for the Super Bowl, The WABL was hard at
work in Barataria Bay collecting marsh cores for Jacob's and Robert's Salinity freshening
experiment. It was a chilly start but a beautiful boat ride out and back from Myrtle
Grove and we did make it back in time for the game ! The picture on the far left
depict Kate working dilligently hammering in core tubes while Jacob supervises. The
picture on the right shows James and Dr. White setting up more cores for hammering
in.
February 2, 2023 HAPPY WORLD WETLANDS DAY !!! The College wrote a story highlighting some of the
College's recent wetlands research. The story is located HERE The Picture is a blast from the past, Dr. White circa 1991 with his MS advisor Dr.
Parkinson after battling red mangroves all day in Florida.
January 2023 - The WABL enters a new semester and a new year. Due to the pandemic and other associated factors, we have a backlog of papers which we are seeking to get out the door and get published. The WABL will try and "catch up" this year with a goal of 14 published papers in 2023, breaking the previous record of 13 papers in one year set in 2012. The problem with doing great science and not getting it published is that no one ever knows what you did. We are well on our way with 3 papers published/accepted, 2 in revision and 3 more in review. We look forward to submitting papers by Jacob, Mercedes, Robert and James in the coming months.
