Statistical correction of lidar-derived digital elevation models with multispectral airborne imagery in tidal marshes

Airborne light detection and ranging (lidar) is a valuable tool for collecting large amounts of elevation data across large areas; however, the limited ability to penetrate dense vegetation with lidar hinders its usefulness for measuring tidal marsh platforms. Methods to ...

Suspended sediment projections in Apalachicola Bay in response to altered river flow and sediment loads under climate change and sea level rise

Suspended sediments, or total suspended solids (TSS), are an important factor for oyster habitat. While high concentrations of suspended sediments can cause a reduction of oyster density, some level of suspended sediment is required to supply oysters with necessary nutrients ...

Terrain-driven unstructured mesh development through semi-automatic vertical feature extraction

A semi-automated vertical feature terrain extraction algorithm is described and applied to a two-dimensional, depth-integrated, shallow water equation inundation model. The extracted features describe what are commonly sub-mesh scale elevation details (ridge and valleys), which may be ignored in standard ...

The dynamic effects of sea level rise on low-gradient coastal landscapes: A review

Coastal responses to sea level rise (SLR) include inundation of wetlands, increased shoreline erosion, and increased flooding during storm events. Hydrodynamic parameters such as tidal ranges, tidal prisms, tidal asymmetries, increased flooding depths and inundation extents during storm events respond ...

The New Fisheries Economics: Incentives Across Many Margins

New research in fisheries economics addresses incentives across many margins. These margins include within-season effects, incentives to harvest different ages and sizes of fish, responses to ecological disturbances, spatial choices, and multispecies interactions. Even developments in global seafood markets are ...

The response of runoff and sediment loading in the Apalachicola River, Florida to climate and land use land cover change

The response of runoff and sediment loading in the Apalachicola River under projected climate change scenarios and land use land cover (LULC) change is evaluated. A hydrologic model using the Soil and Water Assessment Tool was developed for the Apalachicola ...

Tidal hydrodynamics under future sea level rise and coastal morphology in the Northern Gulf of Mexico

This study examines the integrated influence of sea level rise (SLR) and future morphology on tidal hydrodynamics along the Northern Gulf of Mexico (NGOM) coast including seven embayments and three ecologically and economically significant estuaries. A large-domain hydrodynamic model was ...

U.S. Shrimp Market Integration

Recent supply shocks in the Gulf of Mexico—including hurricanes, the Deepwater Horizon oil spill, and the seasonal appearance of a large dead zone of low oxygen water (hypoxia)—have raised concerns about the economic viability of the U.S. shrimp fishery. The ...

Upregulation of hypoxia-inducible factor (HIF)-1α and HIF-2α mRNA levels in dragonet Callionymus valenciennei exposed to environmental hypoxia in Tokyo Bay

There is an urgent need to develop reliable biomarkers of environmental hypoxia exposure in marine organisms in order to assess the ecological impacts of the marked increase in coastal hypoxia worldwide. Full-length hypoxia-inducible factor HIF-1α and HIF-2α cDNAs were cloned ...
