Melissa’s research interests include how pelagic, benthic, and vegetated habitats of coastal ecosystems support functions of nutrient cycling, trophic dynamics of food webs, and carbon sequestration.
Melissa has conducted research on the essential mechanisms and stressors involved in benthic-pelagic coupling of lakes, estuaries, and oceans, including the hypoxic region or Dead Zone in the northern Gulf of Mexico. An objective of her current research is to understand how phytoplankton and microphytobenthos (including potential harmful algal blooms) of coastal ecosystems are influenced by nutrient enrichment, climate change, and coastal restoration.
Melissa uses new and existing short- and long-term field observations, statistical analyses, and ecosystem models at the landscape level to answer ecological research questions and to provide relevant information to policy makers and coastal managers. Melissa enjoys participating and leading collaborative and interdisciplinary projects that generate information to inform stakeholders.

Dissolved organic carbon dynamics and fluxes in Mississippi-Atchafalaya deltaic system impacted by an extreme flood event and hurricanes: A multi-satellite approach using Sentinel-2/3 and Landsat-8/9 data
Transport of riverine and wetland-derived dissolved organic carbon (DOC) spanning tidal wetlands, estuaries, and continental shelf waters functionally connects terrestrial and aquatic carbon reservoirs, yet the magnitude and ecological significance of this variable and its spatiotemporal linkage remains uncertain for coastal deltaic regions, such as Mississippi River Delta Plain, which includes MiAuthorsBingqing Liu, Eurico J.

Coastal Louisiana is currently experiencing high rates of wetland loss and large-scale ecosystem restoration is being implemented. One of the largest and most novel restoration projects is a controlled sediment diversion, proposed to rebuild and sustain wetlands by diverting sediment- and nutrient-rich water from the Mississippi River. However, the impact of this proposed sediment diversion on theAuthorsHoonshin Jung, William K. Nuttle, Melissa Millman Baustian, Tim J. B.

Coastal habitats can play an important role in climate change mitigation. As Louisiana implements its climate action plan and the restoration and risk-reduction projects outlined in its 2017 Louisiana Coastal Master Plan, it is critical to consider potential greenhouse gas (GHG) fluxes in coastal habitats.

PahlA model of the spatiotemporal dynamics of soil carbon following coastal wetland loss applied to a Louisiana salt marsh in the Mississippi River Deltaic Plain
The potential for carbon sequestration in coastal wetlands is high due to protection of carbon (C) in flooded soils. However, excessive flooding can result in the conversion of the vegetated wetland to open water. This transition results in the loss of wetland habitat in addition to the potential loss of soil carbon. Thus, in areas experiencing rapid wetland submergence, such as the Mississippi RiAuthorsDonald R.

Louisiana contains nearly 40% of estuarine herbaceous wetlands in the contiguous United States, supporting valuable ecosystem services and providing significant economic benefits to the state and the entire United States.

Coastal marshes are essential habitats for soil carbon accumulation and burial, which can influence the global carbon budget. Coastal Louisiana has extensive marsh habitats (fresh, intermediate, brackish, and saline) where soil cores were collected to a depth of 100 cm at 24 sites to assess long-term carbon accumulation and burial rates.

Coastal wetlands store more carbon than most ecosystems globally. As sea level rises, changes in flooding and salinity will potentially impact ecological functions, such as organic matter decomposition, that influence carbon storage. However, little is known about the mechanisms that control organic matter loss in coastal wetlands at the landscape scale. As sea level rises, how will the shift fromAuthorsCamille L.

Salinity alterations will likely change the plant and environmental characteristics in coastal marshes thereby influencing soil carbon accumulation rates. Coastal Louisiana marshes have been historically classified as fresh, intermediate, brackish, or saline based on resident plant community and position along a salinity gradient.

Short-term carbon accumulation rates were examined by collecting 10-cm deep soil cores at 24 sites located in marshes spanning the salinity gradient in coastal Louisiana. Percent moisture, bulk density, total carbon content, and the short-term accretion rates obtained with feldspar horizon markers were measured to determine total carbon accumulation and storage rates.
