Lab News

October 1, 2025.  The WABL was out on Lake Pontchartrain as Max, Eddie and Drs. White and Glaspie scouted out for the sandy benthic habitat of the elusive and threatened Gulf Sturgeon fish.  We cored 4 stations getting sections of sediment, intact cores and benthic organisms.

 

 

 

 

 

 

 

 

July 29, 2025  The WABL set off on the second hottest day of the summer to the Davis Pond Freshwater Diversion marsh.   Here, they helped collect more cores, freshwater species this time, for Jey's N dosing experiment.    Another 15 large cores and 4 smaller characterization cores.  Seen in the photo cooling down from left to right is Jey, Noah and Lee.

 

 

 

 

 

 

July 28, 2025  The WABL traveled to Barataria Bay to collect large, vegetated cores for Jey's Masters work which will investigate the relative fate of nitrate in the brackish and salt marshes; plant uptake vs microbial denitrification.  This field work involved high temperatures, limited wind and spikey plants.  At least it seemed too hot for the insects !   Captain Eddie sprays off the mud from the cores as they came aboard (Top left).  Lee takes a core from Nico after he wrestled it ouf the ground (Top right).   Jey proudly displays one of his characterization cores (Bottom left) and Nico wins the award for the muddiest shirt out of the whole crew (Botton right).  Another trip occurs tomorrow to get the plants from the Freshmarsh area near Davis Pond.  These will all head out to the greenhouse where a month-long dosing study will take place. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

July 25, 2025.  Congrats to Nico who was awarded a Graduate Interjurisdictional Research Award Fellowship (GIRAF) for  his project entitled "From Above and Below: Assessing Impacts of Droughts and Storm Surges on Coastal Wetland Health".  The fellowship is a collaboration between LA Sea Grant and LA Sea Grant and comes with a $10,000 stipend paid over the year.  Nco is integrating remote sensing from satellites with salinity measurements across the coast to look at plant health from salinity changes.  You can read more info about the proposed work by clicking HERE

 

 

 

 

 

 

 

 

July 3 - 18, 2025.  Drs. Pardue and White were teaching two study abroad courses, Water Management and Urban Sustainability in London, England.  The class was based at the dorms in Imperial College, South Kensington right next to the Royal Albert Music Hall but had 4 full days of lectures interspersed with 6 days of exploring a number of sites through the city including the Walthanstow Wetlands, a drinking water reservoir for over 3.5 million people, the Institution of Civil Engineerings (right picture), The Cholera Epidemic Walk, Crossness Sewer Pumping Station, Olympic Park with urban drainage design, the Thames Barrier holding back sea and storms to prevent flooding, Cranfield University (Left picture) - the top research dollar university in the UK, dedicated to Industrial ties research,  and other exciting sights.  There were 8 undergraduates from LSU and 5 from Rice University in Houston.

June 10, 2025.  Field Season is underway and the WABL was back at Port Fourchon collected soil cores for Nico's Masters work and Katy's undergraduate Honors thesis.  We visted both Spartina alterniflora marshes (left panel) and Avicennia germinans (black mangrove).   Katy and Nico appear to be playing hide and seek in the mangroves as they collect soil cores from beneath the canopy (right panel).

 

 

 

 

 

June 1-5, 2025.  The WABL organized and hosted the 14 International Symposium on Biogeochemistry of Wetlands and Aquatic Systems here in Baton Rouge, LA.   We had over 150 attendees from 10 different countries and 28 US states.  The next one will be in Florida in 2027.

January 17, 2025  After working very long hours all week helping Ph.D. student Lee sample hundreds of water samples from his GEMS experiment, lab members Riley and Nico take a much needed respite !

 

 

 

 

 

 

 

 

 

 

January 5, 2025.  The WABL continues with sampling in the new year !  This time Captain Eddie took out Dr. White, undergrad Katy, and MS students Nico and Eloho sampling down at Port Fourchon.  The team collected soils samples and intact cores from two different marshes; Spartina grass marsh and Black Mangrove tree marsh.. Climate change has allowed Black Mangroves (see picture) to begin replacing Spartina marshes in coastal Louisiana.  Eloho and Katie are conducting research on how this replacement is affecting wetland biogeochemical cycling of carbon and nitrogen.  Nico is going to return to the marshes and see how they respond to sediment additions.   Mangroves have not typically been found in Louisiana because they are not tolerant to hard freezes but as the climate continues to warm, they have expanded their range from the tropics into the subtropical northern Gulf of Mexico.

 

 

 

 

 

 

 

 

January 3, 2025.  The WABL started the new year off right with a trip to the Lake Pontchartrain Estuary to collect intact cores for a storm effect experiment.  Lee will use equipment that will create storm-induced bedload shear on the sediments to see how large wind events increase phosphorus flux into the water column impacting water quality and potentially feeding algal blooms.  Field guide Eddie Weeks captained the boat while undergraduates Riley and Katie assisted Lee with the coring.

 

 

 

 

 

 

 

 

December 19, 2024.  The WABL gathered to celebrate Nico's undergraduate graduation from the Coastal Environmental Science Program.  Nico's family came down from Tennessee to celebrate as well,  After graduation, we migrated over to the CCE building where Nico gave a tour of the lab to his assembled guests and we popped a few bottles of champagne to wash down a tasty red velvet cake.  This day was made extra special for Nico, because he received his diploma for his Birthday!  Nico will start his Masters with the WABL January 2025 working on Thin Layer Dredge Sediment Placement in Wetlands dominated by Black Mangroves.

 

 

November 13, 2024.  Lee was presenting his research at the Society of Wetland Scientists Meeting held in Taipei, Taiwan this November in the special session organized by Drs. White and Corstanje on Big Data in the Environment.  The conference had 500 attendees.

 

 

 

 

 

 

November 1, 2024.  The WABL participated in the Annual Ocean Commotion where thousands of youngsters descend on the LSU campus to learn all about the environment.  The WABL featured terrestrial vs wetland soils, coring in the mud, a demonstration on water quality improvement and a global C cycling discussion.  Clockwise from Top left panel; Lee, Nico and Alumni Jacob field questions from the students, top right; Lee and Riley demonstrate coring technique (actually playing in the mud) while Nico checks his cores.  Bottom right, Katie is explaining where all the carbon comes from in the atmosphere, and bottom left; Jey answers questions from the students.  Everyone enjoyed the chaos !

 

 

 

 

 

October 17-18, 2024.  The LSU College of the Coast & Environment hosted the Society of Wetland Scientists South Central Chapter Meeting with Adjunct LSU Faculty member, Dr. Jacob Berkowitz organizing the meeting.  The event was highlighted by an evening reception of food and drink at the LSU Center for River Studies.

April 17th and April 19th, 2024.  Graduating undergraduate researcher, James Anderson, presented his Honors Thesis work at the College of the Coast & Environments undergraduate research symposium and two days later, presented at the University-wide research LSU Discover Day.  James received cash prizes for both events for placing in the top 3 poster presentations.  Undergraduate researcher Riley Jenkins presented her preliminary Honor's thesis work at the College's at the college research symposium, as well.  Well Done !

 

April 12, 2024.   Drs. Paul Miller and John White were interviewed on camera by the show "This Week In Louisiana Agriculture" regarding the projections for 11 named storms for the Atlantic Hurricane Season and the potential impacts for coastal wetland erosion"  Watch HERE and the operative section is between 8:26 and 10:44 timestamps.

 

 

 

April 1, 2024.  Congratulations to James Anderson for defending his undergraduate honors thesis today entitled "Hurricanes and Harmful Algal Blooms: Assessing the Legacy P Role in Linking These Events Through a Lake Pontchartrain Estuary Case Study".   His committee included Drs. White, Hiatt and Bargu all from the Department of Oceanography and Coastal Sciences and Dr. Wilson from the Department of Environmental Sciences.  The defense included an open presentation lasting about 25 minutes followed by the closed door defense.  We look forward to James' first draft of his publication before he graduates in May. 

 

 

 

 

 

 

March 29, 2024  We are thankful to Robert for sharing his picture with Louisiana Senator  Bill Cassidy, M.D.  whose office he is assigned to for his NOAA-funded, year long Knauss Fellowship.   Also, we received word today that Robert's first manuscript from his Masters was accepted for publication by Science of the Total Environment.  The paper is titled "Impact of Freshwater River Reconnection on Porewater Salinity and Ammonium Availability in Coastal Brackish Marsh Soils" and becomes WABL manuscript 130!  Congratulations !  There is a paucity of research conducted on coastal freshening, making this paper a critical contribution to the scientific literature, despite the reviewer making us remove the word "paucity" from the text because they felt it was too hard a word to understand.

 

 

 

March 13-15, 2024 Drs. Berkowitz and White organized the 2024 LSU Hydric Soils Identification Workshop during the last part of Spring Break.  Attendees were practitioners from the private sector, state government and included several LSU students.  The 2 1/2 day workshop included classroom instruction on hydric soils indicators as well as two field exercises in describing hydric soils and identifying the hydric soils wetland boundary.

 

 

 

 

March 8, 2024  Jacob Cheng successfully defended his Masters Thesis entitled "The Impacts of Nature-Based Sediment Restoration Practices on Coastal Wetland Soil Biogeochemistry".  His committee included Dr. Jacob Berkowitz and Dr. Matt Hiatt in addition to Dr. White.  Jacob is eagerly preparing his two draft publications to be submitted before graduation this May.

 

 

 

 

 

 

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 comes the hard work of processing all the samples. 

 

 

 

 February 7, 2024  Ph.D stuent 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 Class, 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. 

 

 

 

December 15, 2023  Congratulations to Kate Landholm on her graduation with her undergraduate degree in Coastal Environmental Science.  Kate has been a fixture in the lab for 3 years and we look forward to hearing which graduate program in Coastal Policy she will be attending for her Masters Degree.

 

 

 

 

 

 

 

 

 

December 5, 2023  The WABL crew was back at it on the Lake Pontchartrain Estuary. This time Lee brought along Jacob to assist with coring and sectioning while boat captain Eddie steered a true course.  40% completed for the 160 station mapping of the sediments.  It was cold but nice flat water for coring.  The team posed with their newly issued College of the Coast & Environment T shirts (bottom right).

 

 

 

 

 

 

 

November 18, 2023.  The WABL was out sampling the Lake Pontchartrain Estuary today as part of Lee's Ph.D. research.  He brought along trusty undergraduate researchers Riley and Sam to assist sectioning the cores.  We managed to hit 30 stations out of the eventual 160 stations.  Lee (left panel) was glad to try out field expert, Eddie Weeks, new design corer which doesn't require a piston, a remarkable technological step forward in field work!

October 25, 2023.  The WABL, represented by Lee, Riley, Jacob, James and Kate (missing from picture as she had to run off to class) presented to almost 2000 youngsters at the annual LSU Ocean Commotion at the PMAC.  They discussed the elegance of wetland soils and how important the carbon in soils is  for regulating water quality, for microbial energy and making mudpies !

 

 

 

 

 

 

 

 

 

October 18, 2023.  Jacob Cheng and Riley Jenkins represented the WABL at the College of the Coast and Environment's undergraduate Research Fair today at LSU.  They described how wetlands were important for improving water quality and storing carbon as well as talking with potential undergraduate researchers, how their own experiences conducting research has helped shape their career goals. 

 

 

 

 

 

September 4, 2023.  Dr. White was interviewed by Yale Climate Connections at this year's state of the coast on coastal wetland loss.  Feel free to click HERE to hear the <2 minute elevator speech and click HERE to see the accompany web article.

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 begin a year-long paid Knauss Fellowship funded by NOAA working with Policymakers in Congress 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 Urban 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.  Special thanks to Dr. Ron Corstanje and Dr. Jim Harris for hosting us.

 

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". This research is critical for improving environmental models to better predict what will happen to our coastal marsh vegetation species when we reconnect them with the Mississippi River through a Sediment Diversion, currently under construction.  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 one year Knauss fellowship from NOAA in Washington DC and will begin in early February 2024.  Congratulations !

 

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".  This research is critical for improving modeling for the impact on water quality when we reconnect the coastal marshes with the Mississippi River through a Sediment Diverson, currently under construction.  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.  Congratulations !!  She is excited to work on a new coastal system, the Indian River Lagoon.

 

 

 

June 13-15, 2023  Drs. White and Hiatt were invited to attend a DOE on-site review panel at the Smithsonian Environmental Research Center in Maryland.  The site has impressive real time data collections for forests and coastal wetlands.  This trip has inspired Drs. Hiatt and White to start building a wetland porewater sensor network in coastal Louisiana.  We have acquired over $30,000 in funding from LA Seagrant, NOAA and NSF to start building our sensor network, with 5 purchased and 10 more on order. 

 

 

June 6-7, 2023  Drs. White and Li were invited to attend a NOAA-sponsored workshop in Biloxi, MS aimed at setting up a Habitat Focus Area spanning the LA and MS coastlines that are affected from episodic flood releases from the Mississippi River through the Lake Pontchartrain Estuary out into Mississippi Sound.  We are hopeful this could become the first NOAA-HFA in the Gulf Coast.

 

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 on the impact of Sediment River Diversions for the Louisiana Coastal Master Plan.  The college wrote a story about their research located  HERE  

 

 

 

 

Summer 2023  James spent the summer on a paid internship at the Bonanza Creek Long-Term Ecological Research Program in Fairbanks, Alaska.  The picture is from a tunnel dug into the permafrost by the USACE where James had the opportunity to examine frozen carbon from tens of thousands of years ago.

 

 

 

 

 

 

 

 

 

 

 

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. 

November 25, 2022 - The College of the Coast & Environment had its Awards Convocation after long last.  Pictured are from left to right, undergraduate researcher, Kate Landholm - winner of the Anne Atherton Adrian Endowed Scholarship; Graduate student Jacob Cheng winner of the Warren "Whip" Mermilliod Scholarship; Graduate student Mercedes Pinzon; winner of the Joseph Lipsey Sr Memorial Award and the William H.
