Aquifers, which are essential underground freshwater reservoirs worldwide, are understudied ecosystems that harbor diverse forms of microbial life. This study investigated the abundance and composition of prokaryotic and viral communities in the outflow of five springs across northern Florida, USA, as a proxy of microbial communities found in one of the most productive aquifers in the world, the Floridan aquifer. The average abundances of virus-like particles and prokaryotic cells were slightly lower than those reported from other groundwater systems, ranging from 9.6 × 103 ml−1 to 1.1 × 105 ml−1 and 2.2 × 103 ml …
A Record Of Anthropogenic Effects On Sedimentation In The Manatee River, Florida, Patrick Schwing, Ashanti Johnson
A Record Of Anthropogenic Effects On Sedimentation In The Manatee River, Florida, Patrick Schwing, Ashanti Johnson

Increased sedimentation rates have been attributed to increased anthropogenic activity in watersheds throughout Florida and many parts of the world. The Manatee River, located on the west coast of Florida (USA), like many other coastal watersheds, has experienced depletion in natural resources, increased nutrient loading, and increased pollution. LARs (linear accumulation rates) from watersheds throughout Florida suggest that anthropogenic activity increased bulk sedimentation by as much as 4-fold. The objective of this study was to construct a record of sedimentation and improve upon previous studies by determining individual sedimentary constituent MARs (mass accumulation rates) based on short lived radioisotopes (210Pb …

Tidal inlets are very dynamic systems subject to continuous morphological changes under the action of tides, waves and transported sediments. Although flow and sediment dynamics are interactive, for simplicity, they can be decoupled. By accounting only for astronomic tidal effects, the flood cycle can be approximated by means of potential flow toward a sink while the ebb by the hydrodynamics of a plane jet. Using flow field simulation data, the amount and distribution of the moving sediment can be quantified by employing existing methods for estimation of bedload and suspended sediment transport. The applicability of the model is tested against …
