Hydrobiological characteristics of Shark River Estuary, Everglades National Park
Title
Hydrobiological characteristics of Shark River Estuary, Everglades National Park.
Name/Creator
McPherson,Benjamin F.
Abstract/Description
Water quality in the Shark River estuary was strongly influenced by seasonal patterns of rainfall, water level, and temperature. During the rainy season (summer and early fall) the salinity in the 20-mile long estuary ranged from that of fresh water to half that of sea water while concentrations of dissolved oxygen were low, 2-5 milligrams per liter (mg/l) presumably because, among other factors, microbial activity and respiration were accelerated by high temperature (30-33C). During the dry...

During the rainy season (summer and early fall) the salinity in the 20-mile long estuary ranged from that of fresh water to half that of sea water while concentrations of dissolved oxygen were low, 2-5 milligrams per liter (mg/l) presumably because, among other factors, microbial activity and respiration were accelerated by high temperature (30-33C). During the dry season (late fall through spring) the salinity ranged from 18 grams per liter (g/l) in the headwaters to 36 g/l at the Gulf during a dry year such as 1967 and from 1 to 25 g/l during a wet year such as 1969.

Environment of South Florida
Title
The Environment of South Florida: A Summary Report : a description of the south Florida ecosystem and changes resulting from man's activities.
Name/Creator
McPherson, Benjamin F.
Abstract/Description
This summary report is an overview of the south Florida environment. It is based on and covers the highlights of 51 separate reports prepared as part of the South Florida Environmental Study. The study identified and described the natural ecosystems of south Florida as they functioned before man began to have major impacts on these systems. Where remnants of natural systems still function as before, they were measured and described. The study also encompassed the agricultural and urban...

Nitrogen and Phosphorus Uptake in the Everglades Conservation Areas, Florida, with Special Reference to the Effects of Backpumping Runoff
Title
Nitrogen and Phosphorus Uptake in the Everglades Conservation Areas, Florida, with Special Reference to the Effects of Backpumping Runoff: U.S. Geological Survey Water-Resources Investigations 76-29.
Name/Creator
McPherson, Benjamin F., Waller, Bradley G., Mattraw, H. C., United States, PALMM (Project)
Abstract/Description
In much of the water pumped into the northern Everglades, Florida,concentrations of inorganic nitrogen and phosphorus are relatively high. These nutrients are transported in the canals or into the peripheral marshes. Concentrations decrease sharply within 330 feet or less of the canals, whereas specific conductance remains essentially unchanged within this distance. The sharp decrease in inorganic nitrogen and phosphorus near the canal edge indicates net uptake in these shallow waters....
Show moreIn much of the water pumped into the northern Everglades, Florida,concentrations of inorganic nitrogen and phosphorus are relatively high. These nutrients are transported in the canals or into the peripheral marshes. Concentrations decrease sharply within 330 feet or less of the canals, whereas specific conductance remains essentially unchanged within this distance. The sharp decrease in inorganic nitrogen and phosphorus near the canal edge indicates net uptake in these shallow waters. Concentrations of nitrogen and phosphorus also decrease as water moves through the conservation areas in canals. The authors suggest that the decrease is due partly to dilution by rainfall and runoff, and partly to net uptake in the canals and their peripheral marsh., (DTIC Abstract): Water backpumped into Conservation Areas 1 and 3 is confined largely to canals and peripheral marshes. Water pumped into Area 2 extends into the interior marshes. Water that is backpumped into all three areas can alter water quality in the canals by breaking up water stratification,by resuspending bottom sediments, and by introducing water of a different chemical character. Concentrations of nitrogen and phosphorus decrease as water moves through the conservation areas in canals. This decrease is due partly to dilution by rainfall and runoff, and partly to net uptake in the canals and peripheral marsh. Uptake, estimated for three canals, accounted for a 2-percent decrease in phosphorus per mile and a 4-percent decrease in nitrogen per mile.

Nutrient input from the Loxahatchee River Environmental Control District sewage-treatment plant to the Loxahatchee River Estuary, southeastern Florida
Title
Nutrient input from the Loxahatchee River Environmental Control District sewage-treatment plant to the Loxahatchee River Estuary, southeastern Florida.
Name/Creator
Sonntag, W. H., McPherson, Benjamin F., Florida, Geological Survey (U.S.)
Abstract/Description
The U.S. Geological Survey, in cooperation with 10 local, state, and federal agencies, undertook an in-depth environmental investigation of the Loxahatchee River basin and estuary. One study element of this investigation was to estimate the major input and output patterns of selected chemical constituents to and from the estuary, and to assess the immediate impact of treated-sewage effluent discharges from the ENCON sewage-treatment plant on water quality of the Loxahatchee River.

One study element of this investigation was to estimate the major input and output patterns of selected chemical constituents to and from the estuary, and to assess the immediate impact of treated-sewage effluent discharges from the ENCON sewage-treatment plant on water quality of the Loxahatchee River. Maximum allowable daily discharges of treated-sewage effluent were released to the Loxahatchee River during two periods (February 17-20 and September 14-20, 1981) when streamflow and other environmental conditions varied in response to seasonal changes. Water-quality and discharge data were collected at selected sites, and nutrient loads were computed during both periods. Projections of annual nutrient loading under maximum effluent discharges were made and compared to annual river and tributary loading ot the estuary. In addition, historic information supplied by ENCON on annual effluent discharge from the treatment plant was evaluated and compared to annual river and tributary loading based on U.S. Geological Survey data.

Abstract/Description
This report presents the results of a study to evaluate the effects of inorganic nitrogen and phosphorus additions on phytoplankton productivity and chlorophyll-a concentrations in a subtropical Florida coastal plain estuary and assesses the potential effects of increased nutrient concentrations on future phytoplankton production within the Charlotte Harbor system.

Show moreThis report presents the results of a study to evaluate the effects of inorganic nitrogen and phosphorus additions on phytoplankton productivity and chlorophyll-a concentrations in a subtropical Florida coastal plain estuary and assesses the potential effects of increased nutrient concentrations on future phytoplankton production within the Charlotte Harbor system. The results of this estuarine phytoplankton productivity study are discussed in terms of the seasonal and areal variations in ambient-nutrient concentrations and hydrologic conditions. The potential implications that increased anthropogenic-nutrient inputs may have on primary productivity within specific hydrologically defined areas of the harbor are also examined.

Water Quality in the Southern Everglades and Big Cypress Swamp in the Vicinity of the Tamiami Trail, 1996-97.
Name/Creator
Miller, Ronald L., McPherson, Benjamin F., Haag, Kim H., Geological Survey (U.S.), National Water-Quality Assessment Program (U.S.)
Abstract/Description
The quality of water flowing southward in the Everglades and the Big Cypress Swamp was characterized by three synoptic surveys along an 80-mile section of the Tamiami Trail and along a 24-mile transect down the Shark River Slough, by monthly sampling of a background reference site in the central Big Cypress Swamp, and by sampling of fish tissue for contaminants at several sites near the Trail.
