The flux of dissolved organic carbon (DOC) from mangrove swamps accounts for 10% the global terrestrial DOC to coastal oceans. Recent findings high concentrations mercury (Hg) and methylmercury (MeHg) in mangroves, conjunction with common co-occurrence Hg species, have raised concerns that fluxes may also be large. We used a novel approach estimate export DOC, Hg, MeHg waters mangrove-dominated estuary Everglades National Park (Florida, USA). Using situ measurements fluorescent matter as...
At the fringe of Everglades National Park in southwest Florida, United States, Ten Thousand Islands Wildlife Refuge (TTINWR) habitat has been heavily affected by disruption natural freshwater flow across Tamiami Trail (U.S. Highway 41). As Comprehensive Restoration Plan (CERP) proposes to restore sheet from Picayune Strand Project area north highway, impact planned measures on hydrology refuge needs be taken into account. The objective this study was develop a simple, computationally...
The watershed of the Ten Thousand Islands (TTI) estuary has been substantially altered through construction canals and roads for Southern Golden Gate Estates (SGGE), Barron River Canal, U.S. 41 (Tamiami Trail). Two restoration projects designed to improve freshwater delivery are Picayune Strand Restoration Project, which includes Estates, Tamiami Trail Culverts Project; both part Comprehensive Everglades Plan. To address hydrologic information needs critical monitoring effects these...

The tidal Caloosahatchee River and downstream estuaries have substantial environmental, recreational, economic value for southwest Florida residents visitors. Modifications to the watershed altered predevelopment hydrology, thereby threatening environmental health of in area. Hydrologic monitoring freshwater contributions from tributaries its is necessary adequately describe total inflow constituent loads delicate estuarine system.

A field experiment was conducted at the Levee 4 canal site below control structure G-88 in Everglades agricultural area northwestern Broward County, Florida, to study relation of acoustic attenuation suspended-solids concentrations. Acoustic velocity meter and temperature data were obtained with concurrent water samples analyzed for Two separate frequencies used, 200 500 kilohertz, determine sensitivity frequency measured concentration range. Suspended-solids concentrations collected from...
A hydrologic analysis was made at three canal sites and four tidal along the St. Lucie River Estuary in southeastern Florida from 1998 to 2001. The data included for are stage, 15-minute flow, salinity, water temperature, turbidity, suspended-solids concentration. During period of record, estuary experienced a drought, major storm events, high-water discharge Lake Okeechobee. Flow mainly occurred through South Fork River; however, when flow increased control structures C-23 C-24 Canals,...

Acoustic and optic methods were applied to estimate suspended-solids concentrations in the St. Lucie River Estuary, southeastern Florida. Doppler velocity meters installed at North Fork, Speedy Point, Steele Point sites within estuary. These provide varying flow, salinity, water-quality, channel cross-sectional characteristics. The monitoring site was not used analyses because repeated instrument relocations (due bridge construction) prevented a sufficient number of samples from being...

Abstract The nuclear receptor related 1 protein (Nurr1) is a member of the orphan hormone family whose expression has been associated with several inflammatory diseases. Macrophages are key regulators processes, yet information about role Nurr1 in human macrophages limited. In present study we examined and activity steady state activated monocyte-derived macrophages. Pro- anti-inflammatory were derived vitro by culture blood monocytes hematopoietic cytokines GM-CSF M-CSF, respectively. was...
The U.S. Geological Survey collected stream discharge, stage, salinity, and water-temperature data near the mouths of 11 tributaries flowing into Ten Thousand Islands area Florida from October 2004 to June 2005. Maximum positive discharge Barron River Faka Union was 6,000 3,200 ft3/s, respectively; no other tributary exceeded 2,600 ft3/s. Salinity variation greatest at River, ranging 2 37 ppt, 3 34 respectively. maximums were Wood Little each exceeding 40 ppt. All prior commencement Picayune...
