Imaging Derivative Spectroscopy For Vegetation Dysfunction Assessments, Charles R. Bostater Sep 1998

Imaging Derivative Spectroscopy For Vegetation Dysfunction Assessments, Charles R. Bostater

Ocean Engineering and Marine Sciences Faculty Publications

The practical application of current airborne and future satellite or space station based high spectral resolution (hyperspectral) imagery to vegetative canopies (sparse or dense) and resulting derived bio-physical variables will depend upon our ability to rapidly apply scientifically based algorithms. Key to these rapid assessments is the selection ofthe best or optimal channels or bands for detection of plant stress or dysfunction. Previous work '2,3,4,5 has demonstrated the potential of utilizing high spectral resolution optical signatures for detecting plant stress related to the vegetation's moisture within the leaf structure. Future algorithms and techniques need to discriminate plant species as well …

Passive Margin Sedimentation On Costa Rica's North Caribbean Coastal Plain, Rio Colorado, Randall W. Parkinson, Jorge Cortés, Percy Denyer Jan 1998

Passive Margin Sedimentation On Costa Rica's North Caribbean Coastal Plain, Rio Colorado, Randall W. Parkinson, Jorge Cortés, Percy Denyer

Ocean Engineering and Marine Sciences Faculty Publications

Geomorphic, sedimentologic, and stratigraphic data obtained from the north Caribbean region of Costa Rica suggests Rio Colorado is a wave-dominated delta which has formed along a passive continental margin. This coastal setting is significantly different from the south Caribbean and Pacific coastlines, which display geomorphic and lithologic features indicative of seismically active continental margins. The distinct aseismic history and passive margin geomorphology of the north Caribbean coastal plain appears to be controlled by the presence of tectonic features (i.e., East Nicoya Fracture Zone) which decouple the region from adjacent, tectonically active areas. Although the data collected during this pilot study, …

Effects Of Submergence On Embryonic Survival And Developmental Rate Of The Florida Applesnail, Pomacea Paludosa: Implications For Egg Predation And Marsh Management, Richard L. Turner Jan 1998

Effects Of Submergence On Embryonic Survival And Developmental Rate Of The Florida Applesnail, Pomacea Paludosa: Implications For Egg Predation And Marsh Management, Richard L. Turner

Ocean Engineering and Marine Sciences Faculty Publications

Aerial deposition of egg clutches by the aquatic Florida applesnail is believed to have evolved in response to aquatic egg predators. Adaptation to aerial conditions might, however, have rendered embryos intolerant of submergence, a potential occurrence in natural and managed marshes, rivers, and lakes. In this study, eggs were submerged in water for various durations in the laboratory to assess their ability to survive flooding; and clutches of known ages were submerged for several days in the field to determine if aquatic predators might decrease survival below levels expected to occur due to flooding alone. Submergence of clutches slowed embryonic …

Application Of A Flow-Through Absorption Tube For Remotely Estimating Water-Quality Parameters, Charles Bostater, Melissa Keller, Manuel Gimond Jan 1997

Application Of A Flow-Through Absorption Tube For Remotely Estimating Water-Quality Parameters, Charles Bostater, Melissa Keller, Manuel Gimond

Ocean Engineering and Marine Sciences Faculty Publications

A flow through absorption tube is described and applied. The tube is similar in concept to a 50 cm pathlength cylindrical cuvette described previously by Bostater and Gimond.' The new absorption tube allows for continuous, underway measurements of water absorption signatures. Water is allowed to flow through the tube, and in this way the spectral change or track ofabsorption can be measured as a function oftime or space when operated from a stationary or moving platform. Data gathered from various environments ranging from very turbid to clear water is analyzed and described. Concentrations of chlorophyll-a, suspended matter, and dissolved organic …

Behavior Of Nutrients And Trace Metals In Muck Sediments From A Florida Lagoon, Huan Feng Aug 1992

Behavior Of Nutrients And Trace Metals In Muck Sediments From A Florida Lagoon, Huan Feng

Theses and Dissertations

Fine-grained, organic-rich sediments are a potentially importment reservoir for nutrients and contaminants in the Indian River Lagoon, Florida. However, little is known about the behavior of these chemical species and whether they can be released to the overlying water column. In that regard, this study had two objectives: (1 ) to determine the concentrations of dissolved nitrogen and phosphorus species and some metals in representative muck deposits and the fluxes of these species to the overlying waters of the Indian River Lagoon; and (2) to identify the mechanism controlling concentrations of nutrients and trace metals in these muck deposits. Results …

Impingement Of Organic-Rich, Contaminated Sediments On Manatee Pocket, Florida, John H. Trefry, Nai-Chi Chen, Robert P. Trocine, Simone Metz

Ocean Engineering and Marine Sciences Faculty Publications

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 carbon have an average thickness of about 1 m and a total volume of 340,000 m3 . These deposits formed as soil and organic matter were carried into Manatee Pocket and trapped during the past 100 years of regional development. Vertical profiles for Cd, Cu, Hg, Pb, and Zn show that contamination, at 5-10 times above natural levels, is restricted to the top 15-30% of the organic-rich layers …

Holocene Evolution Of Indian River Lagoon In Central Brevard County, Florida, Sharon F. Bader, Randall W. Parkinson Jan 1990

Holocene Evolution Of Indian River Lagoon In Central Brevard County, Florida, Sharon F. Bader, Randall W. Parkinson

Ocean Engineering and Marine Sciences Faculty Publications

This study examined the coastal response of central Brevard County to rising Holocene sea level as it has been recorded in sediments of Indian River lagoon. The typical Holocene sediment sequence, in ascending order, consists of: (1) depauperate marsh muds, (2) sandy muds and muddy sands that contain a restricted marine fauna, and (3) sands and muddy sands that contain an abundant, more normal marine fauna. This transgressive sequence developed as rising Holocene sea level flooded a Pleistocene topographic depression (paleolagoon). It is often capped by (4) a coarser sand that exhibits a decrease in faunal abundance and diversity. The …

The Geochemistry Of Interstitial Water For A Sediment Core From The Indian River Lagoon, Florida, Deyu Gu, Nenad Iricanin, John H. Trefry Jan 1987

The Geochemistry Of Interstitial Water For A Sediment Core From The Indian River Lagoon, Florida, Deyu Gu, Nenad Iricanin, John H. Trefry

Ocean Engineering and Marine Sciences Faculty Publications

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 sediment column and complete sulfate reduction was observed at a depth of <9 cm below the seawater-sediment interface. Interstitial water chlorinity decreased sharply with depth suggesting subsurface occurrence or intrusion of groundwater. Ammonia, phosphate and silica concentrations were high showing significant nutrient regeneration. Dissolved sulfide levels were also high and play a primary role in controlling interstitial water metal concentrations.

The Seasonality And Spatial Patterns Of Juvenile Surf Zone Fishes Of The Florida East Coast, Dennis J. Peters, Walter G. Nelson Jan 1987

The Seasonality And Spatial Patterns Of Juvenile Surf Zone Fishes Of The Florida East Coast, Dennis J. Peters, Walter G. Nelson

Ocean Engineering and Marine Sciences Faculty Publications

Spatial and temporal patterns of variability were examined (April 1982 - June 1983) for 61 species of surf zone fishes (6,611) at beaches in Melbourne and Sebastian, Florida. The three numerically dominant species, Harengula jaguana, Anchoa lyolepis, and Trachinotus carolinus, comprised over 70 % of all individuals. Temporal and spatial variability at several scales were important aspects of the structure of this fish assemblage. Fishes were most abundant seasonally during spring, summer, and fall (2,659) and least abundant during winter (6). Small scale spatial variability was found on beaches adjacent to the jetties at Sebastian Inlet. Both total number of …

Iron And Copper Enrichment Of Suspended Particles In Dispersed Hydrothermal Plumes Along The Mid‐Atlantic Ridge, John H. Trefry, Robert P. Trocine, Gary P. Klinkhammer, Peter A. Rona Aug 1985

Iron And Copper Enrichment Of Suspended Particles In Dispersed Hydrothermal Plumes Along The Mid‐Atlantic Ridge, John H. Trefry, Robert P. Trocine, Gary P. Klinkhammer, Peter A. Rona

Ocean Engineering and Marine Sciences Faculty Publications

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 dissolved Mn anomalies, suspended matter Fe and Cu values were as high as 15.8% and 1100 µg/g respectively, relative to Al at 1.7%. Suspended matter Fe and Cu values correlate well with dissolved Mn concentrations, tracing the intensity of dispersed plumes. In contrast with Fe and Cu, particulate Mn values in vent plumes were low at 700‐1200 µg/g. Calculated (Al + Fe + Mn)/Al ratios for MAR particles …

Biological Effects Of Dredging In An Offshore Borrow Area, Robert O. Johnson, Walter G. Nelson Jan 1985

Biological Effects Of Dredging In An Offshore Borrow Area, Robert O. Johnson, Walter G. Nelson

Ocean Engineering and Marine Sciences Faculty Publications

Changes in benthic fauna were monitored following excavation of an offshore borrow area in the vicinity of Fort Pierce Inlet, Florida. Sampling stations were established along 2 transects located in the borrow area, 1 control transect north of the borrow area, and 1 control transect south of the borrow area. Results suggest that relatively larger reductions in abundance, but not number of species, of the benthic fauna occurred in the borrow area following dredging as compared with the controls. Therefore the decrease observed appears greater than can be accounted for on the basis of seasonal changes alone. Both parameters returned …

Dissolved Oxygen Concentrations In Florida's Humic-Colored Waters And Water Quality Standard Implications, Thomas V. Belanger, Forrest E. Dierberg, Jerry Roberts Jan 1985

Dissolved Oxygen Concentrations In Florida's Humic-Colored Waters And Water Quality Standard Implications, Thomas V. Belanger, Forrest E. Dierberg, Jerry Roberts

Ocean Engineering and Marine Sciences Faculty Publications

The Florida Department of Environmental Regulation has established detailed dissolved oxygen standards for the various classes of surface water in the state. The results of this study and a review of the literature reveal that many natural humic-colored aquatic systems (usually Class III waters) rarely meet the established 5 mg/L criteria. We believe, based on our studies, that these conditions are natural and do not result from organic pollution. In view of this, we believe a review of the current DER Standard, for humic-colored waters only, is in order.

The Occurrence Of A Toxic Dinoflagellate In The Indian River System, Dean R. Norris Jan 1983

The Occurrence Of A Toxic Dinoflagellate In The Indian River System, Dean R. Norris

Ocean Engineering and Marine Sciences Faculty Publications

References to the toxic dinoflagellate, Gonyaulax monilata Howell, in the Indian and Banana rivers are compiled from published and unpublished sources. The inability of researchers to find motile cells for extended periods indicates that benthic resting cysts or hypnozygotes may be the only source for the seed population.

Factors Influencing Seagrass Ecology In The Indian River Lagoon, John D. Rice, Robert P. Trocine, Gary N. Wells Jan 1983

Factors Influencing Seagrass Ecology In The Indian River Lagoon, John D. Rice, Robert P. Trocine, Gary N. Wells

Ocean Engineering and Marine Sciences Faculty Publications

Effects of water depth, water temperature, light intensity, epiphyte coverage, detrital accumulation and sediment resuspension and shifting on seagrass ecology in the Indian River Lagoon system were studied from April 1977 through June 1979. Seagrass beds containing Halophila engelmannii, Halodule wrightii and Syringodium filiforme located between Cocoa and Grant, Florida, were chosen as sampling sites. Increases in vegetative growth for all 3 seagrass&s occurred in spring and to a lesser extent in fall months. Water temperatures ranged between 22 and 30°C. Decreased detrital accumulation, sediment resuspension and shifting, and water depth, increased light transmission and intensities at the seagrass blade …

Benthic Resting Cysts Of Gonyaulax Monilata Howell And Their Relationship To Red Tides In The Indian River, Florida, Kevin C. Owen, Dean R. Norris Jan 1982

Benthic Resting Cysts Of Gonyaulax Monilata Howell And Their Relationship To Red Tides In The Indian River, Florida, Kevin C. Owen, Dean R. Norris

Ocean Engineering and Marine Sciences Faculty Publications

Gonyaulax monilata cysts were found in the sediments from 13 of 37 stations sampled in the Indian River, Florida. The distribution of cysts appears to be the result of 2 unrelated phenomena. In areas where blooms have occurred in the past, the lack of circulation in the lagoon allows the cysts to accumulate. South of Turkey Creek, cysts are found associated with shellfish beds where no blooms have been reported. It is suggested these cysts have been introduced into shellfish regions with oysters which are annually rafted from areas where G. monilata blooms occur. Blooms of this toxic dinoflagellate can …

Benthic Testacida (Rhizopoda, Protozoa) Of Lake Washington, Brevard County, Florida, Haydee Lena Jan 1982

Benthic Testacida (Rhizopoda, Protozoa) Of Lake Washington, Brevard County, Florida, Haydee Lena

Ocean Engineering and Marine Sciences Faculty Publications

Benthic Testacida from sediments of Lake Washington were studied. The Testacida were extracted using standard foraminiferologic techniques. The determined taxa were photographed using scanning electron microscopy. Twenty-one taxa were found. The majority were cosmopolitan and the most abundant were Difflugia pyriformis and Centropyxis compressa. The Testacida guild was similar to that previously studied in other American and European lakes. However, the type and size of the species were different from those found in soil and mosses.

Comparison Of Benthic Oxygen Demand Measurement Techniques, Thomas V. Belanger Jan 1981

Comparison Of Benthic Oxygen Demand Measurement Techniques, Thomas V. Belanger

Ocean Engineering and Marine Sciences Faculty Publications

Several common methods to measure benthic oxygen demand were compared using measured and literature data. An in situ respirometer technique, a laboratory core-uptake technique and a laboratory flow-through system technique were compared on sand and organic sediment in Lake Washington, Florida. In situ uptake rates were significantly higher than core uptake rates, and this difference was greater for highly organic sediment than sand sediment. Measured and literature uptake values for in situ respirometer and core-uptake techniques with organic sediment were compared and resulted in a relationship (r = .99; P< .01) of the form: in situ uptake (g 2/m 2-hr) = .036 + 1.16 core uptake (g 2/m 2-hr). In many cases both coreuptake and in situ respirometer techniques under estimate oxygen consumption, due to difficulties in obtaining correct water velocities over the sediment surface. In the flow-through system studies, sediment oxygen uptake varied considerably with flow rate and a significant logarithmic relationship (P<.01) was obtained with Lake Apopka, Florida organic sediment. Measurement techniques that simulate field flows are the most accurate, such as the flow through system or the in situ tunnel respirometer technique.

Planktonic Foraminifera Collected By The R/V Melville (1972) In The Southwest Atlantic, Haydee Lena, Silvia Watanabe, Sara Souto

Ocean Engineering and Marine Sciences Faculty Publications

The planktonic foraminiferal fauna was studied from 186 samples collected by the R/V Melville in the Southwest Atlantic Ocean during 1972. The samples were collected in the surface layer (horizontal tows) and throughout the water column from 500-0 m. (vertical tows). Twenty species were recognized (some with various formae). These species can be divided according to their temperature requirements into cold-temperate, warm-temperate, warm and cosmopolitan species. Based on the distribution of these species, 4 types of surface water were determined.

Selected Trace Metals In The Upper St. Johns River And Their Land Use Relationships, Jeffrey A. Leed, Thomas V. Belanger Jan 1981

Selected Trace Metals In The Upper St. Johns River And Their Land Use Relationships, Jeffrey A. Leed, Thomas V. Belanger

Ocean Engineering and Marine Sciences Faculty Publications

Iron, copper and zinc were monitored in the water, sediments, and 4 species of fish of the upper St. Johns River, Florida. Surface water concentrations of total iron commonly exceeded 300 ug/l, the standard established by the Florida Department of Environmental Regulation for waters intended for public consumption (Class I waters). Total iron levels in the upper St. Johns River are regulated by a series of interacting natural processes such as the ironphosphate cycle, inputs from nonartesian groundwater or bank seepage, complexation with dissolved organic compounds, increased land runoff during perids of high flow, and resuspension of bottom sediments during …

Infrared Absorption Study Of Humic Substances From Lake Apopka Sediment, Plankton And The Surrounding Drainage Basin, Thomas V. Belanger Jan 1981

Infrared Absorption Study Of Humic Substances From Lake Apopka Sediment, Plankton And The Surrounding Drainage Basin, Thomas V. Belanger

Ocean Engineering and Marine Sciences Faculty Publications

Infrared absorption spectra were run on humic substances from Lake Apopka sediment samples and compared with spectra from citrus and muck farm humic substances from sediment in the surrounding drainage basin, and also with spectra from autochthonous plankton humic substances. The 1540 cm'1 and 1650 cm' 1 peaks in the plankton and lake sediment samples, in addition to other spectra similarities, indicate that plankton is the probable precursor of lake sediment humic substances. The absorption bands at 1650 cm 1 and 1540 cm 1 are thought to be due to peptide bonds in protein, with amide I absorption occurring at …

Low Frequency Nearshore Current Fluctuations On Florida's Central East Coast, Ortwin Von Zweck, David A. Hale Jan 1979

Low Frequency Nearshore Current Fluctuations On Florida's Central East Coast, Ortwin Von Zweck, David A. Hale

Ocean Engineering and Marine Sciences Faculty Publications

Nearshore current measurements in 10 m of water off Hutchinson Island on Florida's central east coast were obtained over 40 da. Data analyses reveal independent alongshore and crosshelf systems of suhinertial waves superimposed on a weak southward, essentially alongshore mean current. The crosshelf current fluctuations appear to be wind driven, while only the 2-2.8 da alongshore current fluctuations are coherent with windstress.

Measurement Of Wind-Driven Currents In A Lagoon, W. K. Schneider, P. S. Dubbelday, T. A. Nevin Jan 1974

Measurement Of Wind-Driven Currents In A Lagoon, W. K. Schneider, P. S. Dubbelday, T. A. Nevin

Ocean Engineering and Marine Sciences Faculty Publications

Knowledge of the circulation processes and patterns of lagoonal waters is of major importance if their overall biological and physical characteristics are to be more completely understood. In addition, such circulation processes and patterns must be considered in the development of pollution controls. The Indian River actually is a lagoon since it is separated from the ocean by a narrow strip of land; it is moderately saline and has a limited number of inlets. There is visible movement of these waters; however, no evidence of defined circulation processes or patterns has been found reported in the literature.
