From Conservation to Consumption: Genomic Applications in Fisheries Management and Seafood Traceability

Genomic approaches are transforming how we understand and manage aquatic species, from uncovering fish responses to climate change to improving seafood traceability in global markets. This talk highlights innovations that link molecular science with biodiversity conservation, fisheries management, and food security

Crab Bank: The Evolution of an Island Restoration

Janet will discuss the background of rebuilding Crab Bank Seabird Sanctuary from dredged material removed from the deepening of ºÚÁϳԹÏÍø Harbor and the resulting wildlife use of the island in the years since restoration. This will be a descriptive talk about how the project came together before construction, details of the building process, and use of the island by seabirds and shorebirds after restoration as well as other plants and wildlife surveyed on the island.

EXTENDING TOXICOLOGICAL UNDERSTANDING FOR COASTAL AND BRACKISH SPECIES -WITHOUT ANIMAL USE

Extending toxicological understanding for coastal and brackish species - without animal use chemicals impact organisms causing both direct and indirect damage, ranging from cell to whole-body effects, often affecting critical functions like growth, reproduction or behavior. While the focus of toxicology has been in understanding how chemicals impact lab animals through the direct exposure and study of animals, we are moving into a space where animal experimentation are being phased out. This talk will provide a broad overview of the current aquatic space, along side case studies of how my lab is starting to address some of the gaps in this space.

Highlights from forty years and counting of research about salt marsh primary production, biogeochemistry, and vertical accretion.

Since 1984, data from North Inlet, South Carolina salt marshes have shaped marsh equilibrium theory, showing that Spartina alterniflora adjusts growth and vertical accretion in response to sea-level changes. This feedback maintains marsh elevation within a range optimal for plant growth, enabling resilience to sea-level rise (SLR). Spartina also drives nutrient cycles, coordinated by sulfate-reducing bacteria and influenced by lunar cycles. These feedbacks have sustained marshes for millennia. However, current SLR rates at North Inlet and beyond have surpassed a tipping point, threatening marsh survival in the coming decades.

QUANTIFYING LARGE EPISODIC SARGASSUM FLUXES TO THE DEEP OCEAN INTERIOR

Massive Atlantic Sargassum blooms are increasingly influencing ocean biogeochemical cycling. While research has focused on surface dynamics, little is known about subsurface export. We report the first sediment-trap evidence of Sargassum transport to the mesopelagic during the record 2022 bloom, capturing large fragments at 600 m with export rates up to 8 mg m⁻² day⁻¹ over ~100 days. Flux patterns mirrored satellite surface biomass, and molecular markers revealed smaller fragments exported for 150 days. Exported Sargassum contained ~30% carbon, one-third as inorganic carbon from calcium carbonate epibionts. These findings reveal significant, episodic carbon export to the deep ocean, underscoring its underrecognized role in carbon cycling.

WHEN THE ICE AGES CHANGED: TROPICAL PACIFIC LESSONS FOR A WARMING WORLD

With human influence now driving climate change at rates unprecedented in historical records, looking to Earth’s past can help us anticipate how the planet may respond to continued warming. This talk explores climate variability in the Tropical Pacific Ocean over the past 1.5 million years, using chemical clues preserved in deep-sea sediments to reconstruct shifts in ocean circulation, temperature, and air–sea interactions. These records reveal how changes in the tropics have shaped global climate patterns through time and offer valuable perspective on the processes that will influence Earth’s climate in the future.
