Beyond marsh drowning: The many faces of marsh loss (and gain)

G Mariotti - Advances in Water Resources, 2020 - Elsevier
The morphodynamics of tidal marshes is investigated using a novel model
(MarshMorpho2D) that couples 2D tidal dynamics, wave dynamics, mass-conserving …

Marsh edge erosion and associated carbon dynamics in coastal Louisiana: A proxy for future wetland-dominated coastlines world-wide

Y Sapkota, JR White - Estuarine, Coastal and Shelf Science, 2019 - Elsevier
Coastal wetland loss through marsh edge erosion is a serious problem in Louisiana. The
majority of studies on coastal land loss use aerial and satellite photographic analysis while …

Modeling the spatial dynamics of marsh ponds in New England salt marshes

G Mariotti, AC Spivak, SY Luk, G Ceccherini, M Tyrrell… - Geomorphology, 2020 - Elsevier
Ponds are common features on salt marshes, yet it is unclear how they affect large-scale
marsh evolution. We developed a spatially explicit model that combines cellular automata …

Soil organic carbon development and turnover in natural and disturbed salt marsh environments

SY Luk, K Todd‐Brown, M Eagle… - Geophysical …, 2021 - Wiley Online Library
Salt marsh survival with sea‐level rise (SLR) increasingly relies on soil organic carbon
(SOC) accumulation and preservation. Using a novel combination of geochemical …

Mechanisms of pond expansion in a rapidly submerging marsh

J Himmelstein, OD Vinent, S Temmerman… - Frontiers in Marine …, 2021 - frontiersin.org
The development and expansion of ponds within otherwise vegetated coastal marshes is a
primary driver of marsh loss throughout the world. Previous studies propose that large ponds …

Peat decomposition and erosion contribute to pond deepening in a temperate salt marsh

S Luk, MJ Eagle, G Mariotti, K Gosselin… - Journal of …, 2023 - Wiley Online Library
Salt marsh ponds expand and deepen over time, potentially reducing ecosystem carbon
storage and resilience. The water filled volumes of ponds represent missing carbon due to …

Burrowing fauna mediate alternative stable states in the redox cycling of salt marsh sediments

SJ van de Velde, S Hidalgo-Martinez… - … et Cosmochimica Acta, 2020 - Elsevier
Abstract The East Anglian salt marsh system (UK) has recently generated intriguing data
with respect to sediment biogeochemistry. Neighbouring ponds in these salt marshes show …

Pond excavation reduces coastal wetland carbon dioxide assimilation

EB Powell, JR Krause, RM Martin… - Journal of Geophysical …, 2020 - Wiley Online Library
Coastal wetlands comprise important global carbon sinks; however, anthropogenic
disturbance accompanied with accelerating sea level rise threaten their continued survival …

Evaluation of coastal wetland soil properties in a degrading marsh

JF Berkowitz, CM VanZomeren, CD Piercy… - Estuarine, Coastal and …, 2018 - Elsevier
Coastal salt marshes consist of a mosaic of vegetated and open water features, which
naturally evolve and change over time. However, the rapid expansion of open water areas …

Creek dynamics determine pond subsurface geochemical heterogeneity in East Anglian (UK) salt marshes

AM Hutchings, G Antler, JV Wilkening, A Basu… - Frontiers in Earth …, 2019 - frontiersin.org
Salt marshes are complex systems comprising ephemerally flooded, vegetated platforms
hydraulically fed by tidal creeks. Where drainage is poor, formation of saline-water ponds …
