Shellfish Tissue Monitoring In New Hampshire Estuaries 2003 And 2004, Phil Trowbridge Dec 2005

Shellfish Tissue Monitoring In New Hampshire Estuaries 2003 And 2004, Phil Trowbridge

PREP Reports & Publications

The goal of this project was to provide data for two NHEP indicators of estuarine condition: TOX1 and TOX3. These two indicators report on “Shellfish tissue concentrations relative to FDA standards” and “Trends in shellfish tissue contaminant concentrations”, respectively. Both of these indicators depend on data from the Gulfwatch Program. In particular, TOX3 requires annual data at benchmark sites to assess trends. In 2003 and 2004, the NHEP supported the collection and analysis of tissue samples from benchmark sites in Portsmouth Harbor, Hampton-Seabrook Harbor and Dover Point.

Distribution Of Foraging Shearwaters Relative To Inner Front Of Se Bering Sea, J. Jahncke, K. O. Coyle, Stephan I. Zeeman, N. B. Kachel, G. L. Hunt Jr. Dec 2005

Distribution Of Foraging Shearwaters Relative To Inner Front Of Se Bering Sea, J. Jahncke, K. O. Coyle, Stephan I. Zeeman, N. B. Kachel, G. L. Hunt Jr.

Marine Sciences Faculty Publications

We examined the hypothesis that short-tailed shearwaters Puffinus tenuirostris aggregate to forage at the inner front of the SE Bering Sea because of enhanced production there. We tested this hypothesis by comparing primary production, the distribution of euphausiids and the distribution of shearwaters relative to the front during late spring and late summer/early fall of 1997, 1998 and 1999. We found enhanced primary production at the front and offshore of the front during summer but not during spring. Primary production varied between seasons and years. Major differences were related to anomalous conditions in 1997 and 1998. The density of euphausiids …

Estimation Of Iron Solubility From Observations And A Global Aerosol Model, Chao Luo, N. M. Mahowald, N. Meskhidze, Y. Chen, R. L. Siefert, A. R. Baker, Anne M. Johansen Dec 2005

Estimation Of Iron Solubility From Observations And A Global Aerosol Model, Chao Luo, N. M. Mahowald, N. Meskhidze, Y. Chen, R. L. Siefert, A. R. Baker, Anne M. Johansen

All Faculty Scholarship for the College of the Sciences

Mineral aerosol deposition is the dominant source of iron to the open ocean. Soil iron is typically insoluble and understanding the atmospheric processes that convert insoluble iron to the more soluble forms observed over the oceans is crucial. In this paper, we model several proposed processes for the conversion of Fe(III) to Fe(II), and compare with cruise observations. The comparisons show that the model results in similar averaged magnitudes of iron solubility as measured during 8 cruises in 2001–2003. Comparisons show that results of cases including cloud, SO2 and hematite processing are better than the other approaches used using …

Monthly Variability In Florida Bay Benthic Foraminifera Community Structure, C. Featherstone, Patricia Blackwelder Dec 2005

Monthly Variability In Florida Bay Benthic Foraminifera Community Structure, C. Featherstone, Patricia Blackwelder

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Florida Bay is a shallow subtropical estuary, which experiences highly variable environmental fluctuations due to natural forces (hurricanes, climatic variations and sea level rise) and anthropogenic influences (agricultural activity, water management and urbanization). Study of short time-scale variability in benthic community population structure and synchronous environmental change is essential to understanding forcing relationships between environment and its effects on population. Benthic foraminifera assemblage variability is an excellent indicator of environmental change in estuarine and coastal areas because populations may respond relatively quickly on spatial and temporal scales (Alve, 1995). Temporal resolution is enhanced because foraminifera may reproduce as often as …

Revision Of The Genus Bdellamaris (Hirudinea : Piscicolidae) Including A New Combination, Bdellamaris Manteri, J Williams, E Burreson Dec 2005

Revision Of The Genus Bdellamaris (Hirudinea : Piscicolidae) Including A New Combination, Bdellamaris Manteri, J Williams, E Burreson

VIMS Articles

The New Zealand fish leech genus Bdellamaris was revised and a redescription of the type species, Bdellamaris eptatreti, was made using material from Eptatretus cirrhatus, the type host for B. eptatreti. Since the holotype has been lost and paratypes exist only in the form. of frontal sections of approximately one third of a leech, a neotype was designated. Individuals in Bdellamaris lack eyes, ocelli, and conducting tissue and possess 11 pairs of pulsatile vesicles, 6 pairs of testisacs, accessory gland cells on the terminal portion of the male reproductive system, and a seminal receptacle. Bdellamaris eptatreti is characterised by a …

Seagrass–Pathogen Interactions: ‘Pseudo-Induction’ Of Turtlegrass Phenolics Near Wasting Disease Lesions, Latina Steele, Melanie Caldwell, Anne Boettcher, Tom Arnold Nov 2005

Seagrass–Pathogen Interactions: ‘Pseudo-Induction’ Of Turtlegrass Phenolics Near Wasting Disease Lesions, Latina Steele, Melanie Caldwell, Anne Boettcher, Tom Arnold

Biology Faculty Publications

Marine protists of the genus Labyrinthula cause the seagrass wasting disease, which is associated with regional die-offs of eelgrass Zostera marina and also infects turtlegrass Thalassia testudinum . The ability of seagrasses to resist pathogen attack is determined by multiple factors, which are poorly understood. One factor hypothesized to influence seagrass disease resistance is the presence of (poly)phenolic natural products such as caffeic acid, which inhibits the growth of L. zosterae in in vitro laboratory bioassays. This hypothesis has been supported by reports of pathogen-induced phenolic accumulations in eelgrass Z. marina. To test the response of T. testudinum to …

Potential Of Modis Evi And Surface Temperature For Directly Estimating Per-Pixel Ecosystem C Fluxes, Abdullah Rahman, Daniel A. Sims, Vicente D. Cordova, Bassil Z. El-Masri Oct 2005

Potential Of Modis Evi And Surface Temperature For Directly Estimating Per-Pixel Ecosystem C Fluxes, Abdullah Rahman, Daniel A. Sims, Vicente D. Cordova, Bassil Z. El-Masri

School of Earth, Environmental, and Marine Sciences Faculty Publications and Presentations

We tested the potential of estimating per-pixel gross primary production (GPP) directly from the MODIS enhanced vegetation index (EVI) and respiration directly from MODIS surface temperature (MOD11). Carbon flux data were obtained from 10 eddy covariance tower sites representing a wide range of North American vegetations. The correlation between across-site tower GPP and EVI was comparable (r = 0.77) to that between tower GPP and MOD17-GPP (r = 0.73), suggesting that EVI could be used to provide reasonably accurate direct estimates of GPP on a truly per-pixel basis. There was also a strong relationship (r2 = 0.67) between respiration and …

Maximum Size Of Fish Caught With Standard Gears And Recreational Angling, Kevin L. Pope, Gene R. Wilde, Daryl L. Bauer Oct 2005

Maximum Size Of Fish Caught With Standard Gears And Recreational Angling, Kevin L. Pope, Gene R. Wilde, Daryl L. Bauer

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We correlated maximum lengths of freshwater fishes captured during 10 years with standard gears (i.e., gill nets, boat electrofishers and trap nets) and angling from Nebraska water bodies to determine which methodology provided better estimates of maximum size of fishes produced within a given water body. In general, maximum length of fishes captured with standard gears was smaller than maximum length of fishes captured with angling. Although significant (based on sequential Bonferroni adjustment) correlation was found in only one of nine sport fishes assessed, all correlations were positive indicating a general trend between maximum size of fishes captured with these …

Candia Land Conservation And Well Survey Project, Amanda Stone Sep 2005

Candia Land Conservation And Well Survey Project, Amanda Stone

PREP Reports & Publications

Candia’s concern over local development, its rapid growth and encroaching sprawl, and the resulting negative impacts on the natural environment led them to consider taking more serious steps towards environmental protection. This resulted in a two-pronged initiative: a land conservation program, and a survey to collect baseline data about their groundwater resources. With many of the lands overlying identified aquifers not permanently protected, conservation of these lands is critical for preserving the integrity of Candia’s current and future water supplies. The Candia Open Space Committee was a direct outgrowth of the NROC program. With NROC staff assistance, the group formulated …

Distribution Of Hydrogen Peroxide In The Northwest Pacific Ocean, Jinchun Yuan, Alan M. Shiller Sep 2005

Distribution Of Hydrogen Peroxide In The Northwest Pacific Ocean, Jinchun Yuan, Alan M. Shiller

Faculty Publications

[1] Hydrogen peroxide (H2O2) is a reactive oxygen intermediate involved in the cycling of metals and dissolved organic matter. Because little is known of its distribution in the North Pacific Ocean, we determined H2O2 in surface waters continuously and obtained vertical profiles at nine stations during a cruise from Japan to Hawaii. Surface water H2O2 varied from less than 10 to more than 250 nmol dm(-3). A diel cycle in surface water H2O2 (similar to 25 nmol dm(-3)) was observed only on one day during the monthlong cruise. This is contrary to expectations based on the usual assumption of photo-production …

A Comparison Of Diets And Water Agitation Methods For Larval Culture Of The Edible Sea Urchin, Tripneustes Ventricosus (Echinodermata: Echinoidea), Ray Wolcott, Charles G. Messing Sep 2005

A Comparison Of Diets And Water Agitation Methods For Larval Culture Of The Edible Sea Urchin, Tripneustes Ventricosus (Echinodermata: Echinoidea), Ray Wolcott, Charles G. Messing

Marine & Environmental Sciences Faculty Articles

Tripneustes ventricosus (Lamarck, 1816) has been harvested for human consumption in the Caribbean for centuries, where harvest rates occasionally exceed sustainability. Historically a backreef and grass-bed urchin, the species has recently been observed on the forereef where it appears to control macroalgal growth in the absence of Diadema antillarum (Philippi, 1845) (Woodley and Gayle, 1999). Large-scale culturing has the potential to produce T. ventricosus in sufficient numbers for remediation of degraded coral reefs, restocking of nearshore habitats, and development of an aquaculture industry for one or more Caribbean islands. We report the first successful culturing of T. ventricosus from fertilization …
