Land-based nutrient loading to LMEs: A global watershed perspective on magnitudes and sources

Autor: Rosalynn Y. Lee, Sybil P. Seitzinger, Emilio Mayorga

Publikováno v: Environmental Development. 17:220-229

Coastal resource management initiatives in recent years have moved towards ecosystem approaches such as embodied by Large Marine Ecosystems (LMEs). In this study, land-based dissolved inorganic nitrogen (DIN) loading to LMEs was evaluated using a spa

Photobleaching kinetics of chromophoric dissolved organic matter derived from mangrove leaf litter and floating Sargassum colonies

Autor: Richard G. Zepp, G. Christopher Shank, Rosalynn Y. Lee, Erich Bartels, Anssi V. Vähätalo

Publikováno v: Marine Chemistry. 119:162-171

We examined the photoreactivity of chromophoric dissolved organic matter (CDOM) derived from Rhizophora mangle (red mangrove) leaf litter and floating Sargassum colonies as these marine plants can be important contributors to coastal and open ocean C

Production of chromophoric dissolved organic matter from mangrove leaf litter and floating Sargassum colonies

Autor: Richard G. Zepp, Erich Bartels, Rosalynn Y. Lee, Anssi V. Vähätalo, G. Christopher Shank

Publikováno v: Marine Chemistry. 119:172-181

Chromophoric dissolved organic matter (CDOM) strongly absorbs solar radiation in the blue-green and serves as the primary attenuator of water column ultraviolet radiation (UV-R). CDOM interferes with remote sensing of ocean chlorophyll and can contro

Porewater biogeochemistry and soil metabolism in dwarf red mangrove habitats (Twin Cays, Belize)

Autor: W.P. Porubsky, Rosalynn Y. Lee, Karen L. McKee, Ilka C. Feller, Samantha B. Joye

Publikováno v: Biogeochemistry. 87:181-198

Seasonal variability in biogeochemical signatures was used to elucidate the dominant pathways of soil microbial metabolism and elemental cycling in an oligotrophic mangrove system. Three interior dwarf mangrove habitats (Twin Cays, Belize) where surf

Seasonal patterns of nitrogen fixation and denitrification in oceanic mangrove habitats

Autor: Rosalynn Y. Lee, Samantha B. Joye

Publikováno v: Marine Ecology Progress Series. 307:127-141

Mangrove peat soils are home to a variety of microbial communities that may play a vital role in system-level elemental cycling. We examined rates of nitrogen fixation and denitrification in benthic microbial mats on Twin Cays, Belize, a pair of ocea

Benthic microbial mats: important sources of fixed nitrogen and carbon to the Twin Cays, Belize ecosystem

Autor: Rosalynn Y. Lee, Samantha B. Joye

Publikováno v: Atoll Research Bulletin. 528:1-24

We collected surface microbial mats at sites on Twin Cays, Belize to determine rates of primary production and nitrogen transformations. A diverse array of cyanobacteria including filamentous, coccoidal and heterocystous cyanobacteria, as well as pur

Variable nutrient stoichiometry (carbon:nitrogen:phosphorus) across trophic levels determines community and ecosystem properties in an oligotrophic mangrove system

Publikováno v: Oecologia. 179(3)

Our study investigated the carbon:nitrogen:phosphorus (C:N:P) stoichiometry of mangrove island of the Mesoamerican Barrier Reef (Twin Cays, Belize). The C:N:P of abiotic and biotic components of this oligotrophic ecosystem was measured and served to

Thermal evidence of water exchange through a coastal aquifer: Implications for nutrient fluxes

Autor: Samantha B. Joye, Willard S. Moore, Rosalynn Y. Lee, Edward B. Roggenstein, James M. Krest, Glenn Taylor

Publikováno v: Geophysical Research Letters. 29:49-1

[1] We report the discovery of a semi-confined, high permeability zone (HPZ) 2 meters below the sea bed where exchanges between coastal aquifers and the ocean occur. A temperature probe placed in the HPZ recorded a 1°C semidiurnal cycle. The cycle w
