  • Multistressor Interaction of Perfluorooctane Sulfonate PFOS and Temperature in Two Estuarine Fish Species Red Drum Sciaenops ocellatus and Sheepshead Minnow Cyprinodon variegatus
    Multistressor Interaction of Perfluorooctane Sulfonate (PFOS) and Temperature in Two Estuarine Fish Species, Red Drum (Sciaenops ocellatus) and Sheepshead Minnow (Cyprinodon variegatus)
    Thornton, Anna L. ;
    Chung, Katy W.
    2026 | Environmental Toxicology (2026) | PDF
    Perfluorooctane sulfonate (PFOS), a perfluoroalkyl substance (PFAS), is characterized by a long, fluorinated carbon chain which makes it ideal for oil- and water-repellent products but detrimental for the environment, where it persists and accumulates in organisms. PFOS has been detected in coastal ecosystems, but information on impacts to estuarin ...

    Kendall, Matthew S. ;
    Williams, Bethany L.
    2026 | Ecological Solutions and Evidence, 7(2) | PDF
    Many coastal roads lack adequate passageways for water to flow under them in tidal creeks. Ecosystem connectivity can be restored to upstream areas by installing new or larger culverts to improve flow.

    Bost, Molly ;
    Davis, Jenny
    2026 | Estuarine, Coastal and Shelf Science, 338, 109932 | PDF
    Global climate change has inspired fervent investigation into salt marshes as blue carbon sinks and their potential role in mitigating climate change through CO2 drawdown and long-term storage. Conservation and restoration of existing marsh complexes can preserve the valuable carbon stock already in place while reducing marsh vulnerability to erosi ...
  • Predicting Karenia brevis Induced Respiratory Irritation at Individual Southwest Florida Beaches Using Cell Abundances Plus Wind Direction and Speed
    Predicting Karenia brevis Induced Respiratory Irritation at Individual Southwest Florida Beaches Using Cell Abundances Plus Wind Direction and Speed
    Collins, K. M. ;
    Hounshell, A. G.
    2026 | GeoHealth, 10(4) | PDF
    Nearly annually, blooms of the dinoflagellate Karenia brevis form along the southwest Florida coast leading to a variety of negative impacts, including respiratory irritation (RI) in humans. To limit these impacts, NOAA's National Centers for Coastal Ocean Science (NCCOS) developed a RI model to provide beach-goers with a category-based estimate of ...
  • Accounting for Intra and Intergenomic Sequence Variation in Reference Barcodes Improves eDNA Metabarcoding Biodiversity Assessment
    Accounting for Intra- and Intergenomic Sequence Variation in Reference Barcodes Improves eDNA Metabarcoding Biodiversity Assessment
    McCartin, Luke J. ;
    Vohsen, Samuel A.
    2026 | Molecular Ecology Resources, 26(3) | PDF
    Environmental DNA (eDNA) metabarcoding can rapidly characterise biodiversity, yet its accuracy and effectiveness are limited by incomplete DNA barcode reference databases. We evaluated how comprehensive reference databases that include sequence variation within genomes (intragenomic) and across individuals and species (intergenomic) improve eDNA-ba ...
  • The Effect of Biochar on Marsh Phosphorus Retention Implications for P Biogeochemical Ecosystem Services from Prescribed Burns
    The Effect of Biochar on Marsh Phosphorus Retention: Implications for P Biogeochemical Ecosystem Services from Prescribed Burns
    Edris, Pamela C. ;
    Laurent, Kari St.
    2026 | Estuaries and Coasts, 49(3) | PDF
    Mid-Atlantic tidal salt marshes provide a number of ecosystem services including the storage of phosphorus (P) within their soils, which reduces nutrient export to estuaries. The storage of P in marsh soils is vegetation-specific, and management efforts targeting the removal of the invasive common reed, Phragmites australis may reduce the P ecosyst ...
  • Coastal Modeling Vertical Datum Package
    Coastal Modeling Vertical Datum Package
    Cassalho, Felicio ;
    Riley, Jack
    2026 | NOAA technical memorandum NOS CS ; 62 | PDF
    Accurate conversions between vertical datums are a fundamental requirement for operational coastal modeling, storm surge prediction, and inundation mapping. However, integrating standard transformation tools into automated, Python-based modeling workflows is often hindered by software complexity, lack of transparency, and difficulties in handling p ...

  • Beyond Biodiversity Incorporating Uncertainty Into Metabarcoding Data for Improved Inference of Ecological Relationships
    Beyond Biodiversity: Incorporating Uncertainty Into Metabarcoding Data for Improved Inference of Ecological Relationships
    Patin, Nastassia V. ;
    Pitz, Kathleen
    2026 | Molecular Ecology Resources, 26(4) | PDF
    Metabarcoding sequence data from environmental DNA (eDNA) is rapidly expanding as a powerful method for biodiversity surveys. In order to interpret these data, tools are needed that account for the uncertainty associated with eDNA sampling, sequencing and analysis. The data resulting from eDNA marker gene analysis differ from many traditional metho ...
  • A Community risk assessment of flooding and heat hazards in the Baltimore metropolitan area
    A Community risk assessment of flooding and heat hazards in the Baltimore metropolitan area
    Freitag, Amy ;
    Auerswald, Katherine
    2026 | NOAA technical memorandum NOS NCCOS ; 369 | PDF
    Coastal communities are exposed to numerous climate-related hazards, all of which are projected to increase in intensity and frequency in the coming decades. The impacts of these hazards depend on structural and social factors that make coping and recovery more difficult for some communities than others. The study area of the Baltimore metropolitan ...
  • An assessment of contaminants and benthic condition in the Matagorda Bay system Texas USA
    An assessment of contaminants and benthic condition in the Matagorda Bay system (Texas, USA)
    Caillier, Jasmine J. ;
    Montagna, Paul A.
    2026 | Environmental Science and Pollution Research, 33(19), 9785-9803 | PDF
    The Matagorda Bay system has suffered a long-term decline in benthic abundance, biomass, and diversity since the 1980’s. This study examined sediment contamination to determine if legacy pollutants are degrading sediment quality and are a possible cause for ecosystem degradation. Degradation can be indicated by a decline in benthic integrity (i.e., ...
  • Which attributes of restored oyster reefs provide the best habitat for sportfish
    Which attributes of restored oyster reefs provide the best habitat for sportfish?
    Kendall, Matthew S. ;
    Cahill, Brianna V.
    2026 | Restoration Ecology (2026) | PDF
    Introduction Restoration practitioners seek to restore oyster ecosystems as habitat designed for species targeted by recreational fisheries, but they require information on which specific habitat parameters of oyster reefs are preferred by fish. Objectives We evaluated the use of restored oyster reefs with a diverse suite of design characteristics ...

    Unlocking a fish finder for benthic habitat characterization
    Scherer, Michael P. ;
    Schmidt, Val
    2026 | Oceanography 39(2) | PDF
    Single beam sonars can provide valuable acoustic information on the structure of benthic habitats and the contents of the water column. Nominally, acoustic sensors that provide water column data in scientific applications can cost tens or hundreds of thousands of dollars. In contrast, consumer grade fish finders that are mass produced are very inex ...

    2026 | JASA Express Letters, 6(1) | PDF
    Many fish species are suspected to produce sound, but the variety of sounds they produce is still largely undocumented. This study investigated the presence and diversity of fish sounds in the Channel Islands National Marine Sanctuary. Besides regular sounds from three known species-bocaccio (Sebastes paucispinis), plainfin midshipman (Porichthys n ...
