A BSTR ACU The primary concern of this paper is an examination of the utility of spectral techniques in detecting wave modes of the large-scale tropospheric circulation. Sample time-and space-spectra of meridional winds in middle latitudes are presented. A maximum in the spatial spectra of the transient waves at hemispheric wave numbers 5-7 is shown, in(More)
This study addresses water quality conditions across several distinct hydrologic regimes in the Upper Taylor Slough (UTS) region of Everglades National Park and briefly considers implications for long-term water quality management. Due to upstream changes in water delivery and construction of a detention area, Taylor Slough has experienced a significant(More)
We would like to invite the CLIVAR community to submit CLIVAR related papers to CLIVAR Exchanges for the next issue. The deadline for submission is 31st August 2008 Guidelines for the submission of papers for CLIVAR Exchanges can be found CLIVAR is an international research programme dealing with climate variability and predictability on timescales from(More)
We developed a cryogenic transimpedance amplifier that works at a broad range of temperatures, from room temperature down to 4 K. The device was realized with a standard complementary metal oxide semiconductor 1.5 mum process. Measurements of current-voltage characteristics, open-loop gain, input referred noise current, and power consumption are presented(More)

The aim of this study was to evaluate Gambusia spp. (mosquito-fish) mercury bio-concentration factor in relation to marsh surface water sulfate concentration. As part of the everglades regional environmental monitoring and assessment marsh biogeochemical parameters were collected by the US Environmental Protection agency between 1995 and 2005 within the(More)

This study evaluated the degree of sediment contamination in several South Florida estuaries. During the 2010 National Condition Assessment, Florida Fish and Wildlife Research Institute collected water column, sediment and biotic data from estuaries across the entire state of Florida. Sediments were analyzed for arsenic, cadmium, chromium, lead, mercury,(More)
This study evaluates factors, particularly water quality related, that may influence mercury (Hg) bioaccumulation in largemouth bass (LMB, Micropterus salmoides Lacépède) within the Everglades marshes of South Florida. The investigation is an empirical analysis of ambient data from both long-term fish monitoring and marsh water quality monitoring sites(More)
