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...
Abstract Caretta caretta (loggerhead sea turtle) nesting activity was recorded daily during three seasons prior to and two immediately following a beach nourishment (replenishment) project in Palm Beach County, Florida. Surveys were done at the nourished (Jupiter/Carlin) natural beaches (Juno Tequesta). The size of effect on estimated using Before‐After‐Control‐Impact Paired Series (BACIPS) models. Nesting declined by 4.4 5.4 nests km − 1 day compared first season after nourishment. At same...
Abstract As part of a two-phased study, sediment and biota were collected from Pennekamp Coral Reef State Park Key Largo National Marine Sanctuary analysed for organochlorine pesticide residues. Phase 1 consisted an inter-laboratory comparison using replicates unspiked field samples. The five participating contract-laboratories differed in methodology, detection limits their ability to detect pesticides. highest concentration reported samples was 4.4 ng g−1 wet wt aldrin, found fillet...
Abstract Total mercury and stable isotopes of nitrogen (δ 15 N) were measured in samples from 57 species invertebrates (17 species) finfish (40 the coastal waters off southwest Florida, USA, to evaluate biomagnification through food web. Mercury concentrations (wet wt) δ N values highly variable among species, ranging 0.004 mg/kg an unidentified brittlestar (class Ophiuroidea) 2.839 ± 1.39 king mackerel ( Scomberomorus cavalla ) 4.67‰ a Florida fighting conch Strombus alatus 13.68‰ crevalle...
Several authors have called attention to pollution and the insidious deterioration of nearshore waters associated marine habitats Florida Keys. Some recognized potential sources that been reported are sewage effluents (Bright et al., 1981; LaPointe & O'Connell, 1988), marinas (Heatwole, 1987), surface water run-off from urban areas in Keys 1987) southeast mainland (Jaap, 1984), wastes fish processing facilities shipping oil spills 1975, 1984; Romero Zheng Van Vleet, 1988). Although any these...
ABSTRACT This case study summarizes an assessment of risk methylmercury (MeHg) exposure to fish–eating birds foraging at Stormwater Treatment Area–2 (STA–2). was required as a special condition for permit modification authorizing flow–through operation STA–2 Cell 1 without it first satisfying formal mercury start–up criteria. The estimates the risks posed by MeHg great egret (Ardea albus) and bald eagle (Haliaeetus leucocephalus). Exposure models were based on literature–derived life history...
An analytical method is described for obtaining the precise location of an absorption line and pressure broadening coefficients due to self-broadening or foreign gas from experimental measurements using a laser operating on single near line. These characteristics are obtained dependence transmittance radiation interest, analysis involving least squares fit family Lorentz curves. The includes computer search region best profile provides both values errors in above coefficients. coefficient...
A survey of sea-surface microlayer (SSML) toxicity was initiated off the Florida Keys in early 1993. Ex situ tests, based on development sea urchin, Lytechinus variegatus, demonstrated that 59.2% SSML samples taken from visibly slicked areas (n=27) were toxic compared to collected subsurface water. random subset tested a second time using fish life-stage test with embryos spotted seatrout, Cynoscion nebulosus, confirmed presence toxicant. Results partial identification evaluation (TIE)...
