February 21, 2024  The Coastal Studies Institute at LSU turned 70 years old today!  We celebrated with a party at the WWII museum in New Orleans.  The AGU Ocean Sciences Meeting was ongoing in New Orleans so we had many alumni come to the event.  Pictured with Dr. White is Dr. Emily Smith who works for NOAA in DC and worked with the WABL on Lake P estuary research, Dr. Larry Rouse, former DOCS department chair and now retired faculty member and Robert Feder, who graduated from the WABL in 2023 and is doing a Knauss Fellowship in Congress, Washington DC.

 

 

 

February 20, 2024  The Lake P estuary has officially been completely sampled by Lee and his team.  It took 5 all-day trips to get all 160 stations for the 0-5 and 5-10 cm sediment depths.  With replicates, this comes to about ~350 total samples . . . and now come the processing of the samples. 

 

 

 

 February 7, 2024  Lee, and yes he has only one field shirt, was once again dragging folks out on the Lake Pontchartrain estuary.  The left panel shows stalward captain Eddie watching Lee manipulate the coring device that he built which requires no piston.  The right panel show Lee and Jacob sectioning sediment into 0-5 cm and 5-10 cm sections.  This was trip 4 of 5 to evantually collect sediment from 160 stations to eventually complete a sediment map of the estuary.  This map will be the basis for more detailed research focused on nutrient triggers leading to harmful algal blooms.

February 1, 8, 2024  Riley ventured out twice, to the wetlands along the northeast part of Lake Pontchartrain estuary with Dr. Quirk's field group to collect soils from a  dredge-material created wetland site as well as a nearby natural marsh.  For the OCS3999, Supervised Research, she will be characterizing the soils for various physiochemical characteristics.  For her Honor's thesis research, Riley will be conducting core flux experiments examining Nitrogen flux.

 

 

 

 

 

 

January 7-11, 2024  Dr White presented at the 11th BIOGEOMON International Symposium on Ecosystem Behavior held at the University of Puerto Rico - Rio Piedras Campus.  The presentation included some of Mercedes Pinzon's Masters work on nitrogen cycling in the face of a river diversion.  We have been invited to submit this work to a special issue of Biogeochemistry. The submission is Due June 1, so Mercedes is balancing her research for her Ph.D. at UCF while working with the WABL to get this paper submitted.

March 26, 2023  The WABL was out on the Lake Pontchartrain Estuary collecting cores for James' and Kate's undergraduate research project.  They plan to investigate the relative amounts of P released through normal estuarine conditions vs when a large storm comes through.  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.  This 2 1/2 day course combines classroom teaching with hands on field work identifying the hydric soils indicators for our Land Resource Regions while also learning about indicators used in other parts of the country.  Here we are down by the Mississippi River levee identifying hydric soils indicators.

 

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 and we have valued our decade long relationship with the school and teacher Ms Mary Ellen Day. 

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, from Florida Institute of Technology in Melbourne, FL after battling red mangroves all day in St Lucie County, 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.

September 5, 2020—Congrats to Yadav! His most recent paper documenting higher carbon stocks deep in the coastal wetland profile susceptible to erosion and mineralization to CO2 was made available online today, though officially will be a publication in 2021.

August 30, 2020—Yadav visited his coastal wetland erosion sites in Barataria Bay to investigate if the passage of nearby but not direct strike storms Marco and Laura had an impact on the marsh erosion rates. Preliminary data suggests that the erosion rate was more than 40 times the normal rate for both storms.

July 12, 2020—Erol made a foray out to the Lake Hermitage Marsh Creation Project, now ~6 years since construction. His goal is to determine the trajectory of wetland ecosystem processes recovery compared to a natural marsh.

Peter is now employed by ENCOS Environmental and Coastal Services, a Baton Rouge-based environmental consulting company focused on
Environmental, Compliance, Coastal Services, and Industrial Hygiene.

 

 

 

 

 

 

 

 

March 18, 2020—Congrats to Alina! Her first master's manuscript was published in Estuarine, Coastal and Shelf Sciences after an excruciating-long review process of seven months. Good things come to those who wait. This research was carried out with Dr. Corstanje’s environmental and agricultural informatics groups at Cranfield University, UK.

March 2, 2020—Congrats to Laura who successfully defended her thesis entitled “Sediment Biogeochemistry of Dredge Pits in the Northern Gulf of Mexico Shelf.” Laura is moving to the “Sunshine State” where she has been hired by Harbor Branch Oceanographic Institute at FAU.

WABL Hits Manuscript 100 !—The lab just hit a significant milestone in 2020. Manuscript 100 was just published! This accomplishment is due to all the hardworking students and great collaborators who have helped build our wetlands program over the years. Perhaps fitting that manuscript 100 includes 3 former students and one current student as co-authors.

November 13, 2019—Congratulations to our PhD student Yadav Sapkota for being selected as a finalist from the wetland soil division of the International Soil Science Society of America meeting held in San Antonio. Yadav won the third place cash award for 5-minute oral and poster presentation in the society-wide competition. #WABL #Bluecarbon #GeauxYadav

October 24, 2019—Dr. Cook’s and Dr. Xue’s Lab joined the WABL in Welcoming Baton Rouge Area students to “Ocean Commotion," a LA SeaGrant sponsored event which engages students on environmental issues relevant to their lives along one of the most dynamic coastlines in the world. The panel at the left show various student groups learning about soil carbon and creating artwork entitled “Carbon Handprints and Fingerprints."

September 15, 2019—Yadav posted his recently accepted paper on the WABL Wall of Achievement, "Carbon offset market methodologies applicable for coastal wetland restoration and conservation in the United States: A review," in Science of the Total Environment. Congrats!

August 2, 2019—Congratulations to Alina Spera on her graduation with her master's degree. Alina’s research was the first temporal and spatial analysis of a large river diversion in Louisiana on coastal wetland soil properties. This project provides valuable information to the state on future operation of the surface water diversions and new restoration efforts. She sets off to work on her PhD looking at climate change in the Arctic with Dr. Lougheed at UTEP.

May 31. 2019—Congrats to Jessica! Her first master's manuscript was published in Science of the Total Environment. This paper was written in collaboration with Dr. Ehab Meselhe from Tulane University.

May 10, 2019—Congratulations to Jessica Vaccare on her master's degree for her research on quantifying water quality ecosystem services in coastal wetlands affected by erosion. Jessica has accepted a job and is in Florida working for an environmental consulting company.

December 14, 2018—Congratulations to Katie Bowes on graduating with her master's for research on impact of surface water temperature on resulting water quality function of wetland soil and submerged sediments. Katie is working in East Central Florida for Martin County, in the Ecosystem Restoration and Coastal Engineering Division.
