Chemical Forms of Nitrogen in Runoff from Diverse Florida Watersheds
Voelker, Jessica Emily (2016-12)Watershed use along the Indian River Lagoon (IRL) on the central east coast of Florida has changed drastically during the past century, bringing with it declining water quality, eutrophication, hypoxia and fish kills. ... -
FREQUENCY DISTRIBUTION PATTERNS AND PARTITIONING OF COPPER, IRON AND ZINC IN SELECTED TISSUES OF THE BLACK MULLET (MUGIL CEPHALUS)
Venuto, Charles J.; Trefry, John H. (1983)Copper, iron and zinc concentrations were determined for muscle, gill and liver tissue from 45 black mullet (Mugil cephalus) collected in Turkey Creek, an embayment of the Indian River Lagoon, Florida. In the liver, Fe ... -
The geochemistry of interstitial water for a sediment core from the Indian River Lagoon, Florida
Gu, Deyu; Iricanin, Nenad; Trefry, John H. (1987)Chemical results for interstitial water from organic-rich sediments in the Indian River Lagoon, Florida, show a classic picture of biogeochemical reactions in anoxic environments. Interstitial nitrate was depleted throughout ... -
THE GEOCHEMISTRY OF INTERSTITIAL WATER FOR A SEDIMENT CORE FROM THE INDIAN RIVER LAGOON, FLORIDA
Gu, Deyu; Iricanin, Nenad; Trefry, John H. (1987)Chemical results for interstitial water from organic-rich sediments in the Indian River Lagoon, Florida, show a classic picture of biogeochemical reactions in anoxic environments. Interstitial nitrate was depleted throughout ... -
IMPINGEMENT OF ORGANIC-RICH, CONTAMINATED SEDIMENTS ON MANATEE POCKET, FLORIDA
Trefry, John H.; Chen, Nai-Chi; Trocine, Robert P.; Metz, Simone (1992)Fine-grained, organic-rich sediments are adversely impacting portions of the coastal zone in Florida. One extreme example is found in Manatee Pocket, on the southeastern coast of Florida, where sediments with >4% organic ... -
Iron and copper enrichment of suspended particles in dispersed hydrothermal plumes along the mid‐Atlantic Ridge
Trefry, John H.; Trocine, Robert P.; Klinkhammer, Gary P.; Rona, Peter A. (1985-08)Particulate Fe and Cu concentrations are used in conjunction with dissolved Mn values to identify hydrothermal venting at several sites along the Mid‐Atlantic Ridge (MAR). In dispersed hydrothermal plumes, as defined by ... -
Metals in sediments and clams from the Indian River Lagoon, Florida
Trefry, John H.; Trocine, Robert P. (2011)A 1992 survey of metal concentrations in sediments and clams from the Indian River Lagoon, Florida, was repeated during 2006–7. Concentrations of Cr, Ni, Se and V in sediments were at background values during both surveys ... -
TRACE METALS IN THE INDIAN RIVER LAGOON, FLORIDA: THE COPPER STORY
Trefry, John H.; Sadoughi, Mehrdad; Sullivan, Michael D.; Steward, Joel S.; Barber, Scott (1983)Inputs of copper from anti-fouling paints presently pose an environmental stress on some restricted embayments of the Indian River Lagoon, Florida. Over an 18 mo period, samples of water, suspended matter, sediments, ... -
Transport of spring floodwater from rivers under ice to the Alaskan Beaufort Sea
Alkire, Matthew B.; Trefry, John H. (2006-12-08)Spring floods carry Alaskan river water north to a frozen Beaufort Sea. A plume of water from the Sagavanirktok River (SR) was identified and traced by measuring salinity, δ18O, and dissolved silica in discrete water samples ...
