Baseline data for a hydrological restoration of a mangrove forest near Goodland, Florida (2015 - 2017) Mangrove restoration has a strong potential to enhance the services provided by coastal wetlands on a number of Department of the Interior (DOI) managed lands throughout the southeastern United States of America. Services include storm protection, water quality improvement, and biological carbon sequestration. Forest structural attributes including basal area, tree height, and stem density by species are used to calculate above ground biomass and above ground productivity. Percent cover is used to asses the forest canopy health. The data collected for the soils are: bulk density, percent total Nitrogen, percent total Carbon, and selected samples percent total Phosporus. The forest structure plots were placed in...

Stable isotope analysis and Bayesian ellipses documented deep-sea food web structure and trophic niches in Baltimore Canyon and the adjacent open slopes in the U.S. Mid-Atlantic Region. Results revealed isotopically diverse feeding groups, comprising approximately 5 trophic levels. Regression analysis indicated that consumer isotope data are structured by site (canyon vs. slope), feeding group, and depth. Benthic feeders were enriched in 13C and 15N relative to suspension...

Although habitat types influence deepwater fish distribution, whether different rugged seafloor features provide functionally equivalent habitat for fishes is poorly understood. In the northeastern Caribbean, numerous rugged seafloor features (e.g., seamounts, banks, canyons) punctuate insular margins, and thus create a remarkable setting in which to examine demersal fish communities across various seafloor features. Also in this region, several water masses are vertically layered...
