COMPARISON OF BENTHIC OXYGEN DEMAND MEASUREMENT TECHNIQUES
(1981)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 ... -
A redescription of Echinaster Modestus Perrier, 1881 (Asteroidea: Spinulosida) from the eastern Gulf of Mexico and the West Indies
(1981-05)The seastar Echinaster modestus Perrier, 1881, is redescribed and a lectotype is designated. Echinaster spp. from the west coast of Florida used in recent experimental studies are not E. modestus. -
Genetic recombination in Nocardia asteroides
(1981-09-04)Gene recombination between strains of N. asteroides of diverse origins has been demonstrated. In particular pairwise combinations, recombinants made up 0.01% of the population. All nine selectable recombinant classes were ... -
BENTHIC RESTING CYSTS OF GONYAULAX MONILATA HOWELL AND THEIR RELATIONSHIP TO RED TIDES IN THE INDIAN RIVER, FLORIDA
(1982)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 ... -
LOCUS-OF-CONTROL IN AN INTERACTIONIST APPROACH TO BEHAVIOR
(1982)The impetus for this empirical study is: 1) to provide further construct validity for the I-E scale; and 2) to advance the locus-of-control construct as an important concept in the growing theoretical model of interactionism. ... -
BENTHIC TESTACIDA (RHIZOPODA, PROTOZOA) OF LAKE WASHINGTON, BREVARD COUNTY, FLORIDA
(1982)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 ... -
TRACE METALS IN THE INDIAN RIVER LAGOON, FLORIDA: THE COPPER STORY
(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, ... -
FACTORS INFLUENCING SEAGRASS ECOLOGY IN THE INDIAN RIVER LAGOON
(1983)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 ... -
COMPUTER SIMULATION OF LIGHT ATTENUATION
(1983)A computer simulation model developed to study light attenuation in the ocean was applied to clear, medium turbid and turbid waters under diverse conditions. The model theory is based upon multiple small angle scattering ... -
THE OCCURRENCE OF A TOXIC DINOFLAGELLATE IN THE INDIAN RIVER SYSTEM
(1983)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 ... -
FREQUENCY DISTRIBUTION PATTERNS AND PARTITIONING OF COPPER, IRON AND ZINC IN SELECTED TISSUES OF THE BLACK MULLET (MUGIL CEPHALUS)
(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 ... -
COMPUTER SIMULATION OF LIGHT ATTENUATION
(1983)A computer simulation model developed to study light attenuation in the ocean was applied to clear, medium turbid and turbid waters under diverse conditions. The model theory is based upon multiple small angle scattering ... -
Activity coefficient and the Einstein relation
(1983-07-15)A connection between the activity coefficient of current carriers and the Einstein relations is established by two methods, one based on normal semiconductor concepts and one based on irreversible thermodynamics. The ... -
A NEW METHOD FOR IMPROVED FIXATION OF THE CHICK'S INNER EAR
(1984)Our method for fixation of the chick's inner ear involves puncturing the soft temporal bone with a needle and directly flushing the membranous labyrinth with cold glutaraldehyde. The temporal bone is trimmed and immersed ... -
Echinaster graminicola, a new species of spinulosid sea star (Echinodermata: Asteroidea) from the west coast of Florida
(1984-06)A new species of the sea-star genus Echinaster is described from shallow-water seagrass and oyster beds of the west coast of Florida. The new speciesand E. spinulosus Verrill are sibling species, morphologically ... -
ON FINITE ELEMENT METHODS FOR THE EULER-POISSON-DARBOUX EQUATION.
(1984-12)We deal primarily with the derivation of various convergence estimates for some semidiscrete and fully discrete procedures which might be used in the approximation of exact solutions of initial-boundary value problems with ... -
BIOLOGICAL EFFECTS OF DREDGING IN AN OFFSHORE BORROW AREA.
(1985)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 ... -
DISSOLVED OXYGEN CONCENTRATIONS IN FLORIDA'S HUMIC-COLORED WATERS AND WATER QUALITY STANDARD IMPLICATIONS
(1985)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 ... -
Iron and copper enrichment of suspended particles in dispersed hydrothermal plumes along the mid‐Atlantic Ridge
(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 ... -
Focused Acoustic Wave (Faw) Channelizer
(1986-09-24)The architecture, operation, and performance of a new integrated acoustic RF channelizer are described. The all- acoustic device uses a phased array piezoelectric transducer to generate frequency dispersed bulk acoustic ...
