The Contribution Of Local And Transport Processes To Phytoplankton Biomass Variability Over Different Timescales In The Upper James River, Virginia, Qubin Qin, Jian Shen 2018 Virginia Institute of Marine Science

The Contribution Of Local And Transport Processes To Phytoplankton Biomass Variability Over Different Timescales In The Upper James River, Virginia, Qubin Qin, Jian Shen

Articles

Although both local processes (photosynthesis, respiration, grazing, and settling), and transport processes (advective transport and diffusive transport) significantly affect local phytoplankton dynamics, it is difficult to separate their contributions and to investigate the relative importance of each process to the local variability of phytoplankton biomass over different timescales. A method of using the transport rate is introduced to quantify the contribution of transport processes. By combining the time-varying transport rate and high-frequency observed chlorophyll a data, we can explicitly examine the impact of local and transport processes on phytoplankton biomass over a range of timescales from hourly to annually. For ...


Environmental Assessment Of Road Brining And Injection Wells For Disposal Of Oil And Gas Liquid Waste, Marissa Madia 2018 Duquesne University

Environmental Assessment Of Road Brining And Injection Wells For Disposal Of Oil And Gas Liquid Waste, Marissa Madia

Electronic Theses and Dissertations

The dramatic increase in oil and gas drilling operations in Pennsylvania over the last decade has presented a challenge for their wastewater disposal (e.g., flowback, produced water). Currently, these fluids are treated in permitted brine treatment plants or exported out of state to deep injection well facilities. In Pennsylvania, road brining for dust control is permitted for conventional well brines, and permits for three injection wells for unconventional brines are pending. This study focused on water quality impacts due to road brining in Farmington Township (45 samples) and ground and surface water in Grant Township (41 samples) prior to ...


2018 Chapman Environmental Audit: Sustainable Purchasing Policy, KC Hoppel 2018 Chapman University

2018 Chapman Environmental Audit: Sustainable Purchasing Policy, Kc Hoppel

Student Research Day Abstracts and Posters

Chapman University maintains its commitment to a “campus culture that promotes a sustainable future” in its Sustainability Policy, which was implemented in 2014. However, the University currently has no mechanism to ensure this sustainable decision-making process occurs. One of the surest ways to guarantee this change is to enact a University-wide sustainable purchasing policy that ensures consistency between departments. Institutions benefit from sustainable procurement by receiving more efficient and long-lasting products, protecting and enhancing the local and global environment, supporting innovative technologies, creating a diverse supply chain, and gaining a competitive edge as a leading institution. A few cost-benefit analyses ...

Dr. John T. Tanacredi

As I sat there in the Members Lounge at the Explorers Club; the world center for exploration, getting ready for our first Spring Saturday Science for Students @the EC lecture, I was putting together some notes on the accomplishments of our science students and CERCOM over the last few months since our last newsletter. Our visit to the Galapagos, a spectacular academic experience for our Molloy College students was at the top of my list! This was certainly not an epiphany but as I accumulated the items on this list, I was impressed not only with what we have conducted ...

A Comparison Of Four Wetlands Assessment Procedures Relevant To The Alluvial Valleys Of East Texas, Amy Camp 2018 Stephen F Austin State University

A Comparison Of Four Wetlands Assessment Procedures Relevant To The Alluvial Valleys Of East Texas, Amy Camp

Electronic Theses and Dissertations

Currently several methods are used by public and private entities to assess wetland functional condition in support of the Section 404 Clean Water Act program. Four of these are: Forested Wetlands in Alluvial Valleys of the Coastal Plain of the Southeastern United States (SEHGM); A Regional Guidebook for Applying the Hydrogeomorphic Approach to the Functional Assessment of Forested Wetlands in Alluvial Valleys of East Texas (ETXHGM); Texas Rapid Assessment Method (TXRAM); and the Wildlife Habitat Appraisal Procedure (WHAP). Little previous research compares wetland functional assessment methods. Results of the SEHGM, ETXHGM, TXRAM, and WHAP methods were compared on five East ...

This study considers the various factors that regulate nutrients supply in the Red Sea. Multi-sensor observation and reanalysis datasets are used to examine the relationships among dust deposition, sea surface temperature (SST), and wind speed, as they may contribute to anomalous phytoplankton blooms, through time-series and correlation analyses. A positive correlation was found at 0–3 months lag between chlorophyll-a (Chl-a) anomalies and dust anomalies over the Red Sea regions. Dust deposition process was further examined with dust aerosols’ vertical distribution using satellite lidar data. Conversely, a negative correlation was found at 0–3 months lag between SST ...

Does Scale Matter? A Systematic Review Of Incorporating Biological Realism When Predicting Changes In Species Distributions, Sydne Record, Angela L. Strecker, Mao-Ning Tuanmu, Lydia Beaudrot, Phoebe Zarnetske, Jonathan Belmaker, Beth Gerstner

Environmental Science and Management Faculty Publications and Presentations

Background: There is ample evidence that biotic factors, such as biotic interactions and dispersal capacity, can affect species distributions and influence species’ responses to climate change. However, little is known about how these factors affect predictions from species distribution models (SDMs) with respect to spatial grain and extent of the models.

Objectives: Understanding how spatial scale influences the effects of biological processes in SDMs is important because SDMs are one of the primary tools used by conservation biologists to assess biodiversity impacts of climate change.

Data sources and study eligibility criteria: We systematically reviewed SDM studies published from 2003–2015 ...


A Hydrologic And Hydraulic Analysis Of Massie’S Creek Gorge, Greene County, Oh, Using Hec-Ras, Joshua W. Perez 2018 Cedarville University

A Hydrologic And Hydraulic Analysis Of Massie’S Creek Gorge, Greene County, Oh, Using Hec-Ras, Joshua W. Perez

The Research and Scholarship Symposium

Massie’s Creek is a small tributary of the Little Miami River, located in southwest Ohio near the village of Cedarville. For approximately 1.5 miles (2.4 km) it flows westward through the Indian Mound Reserve Park, an area which occasionally undergoes flooding. In the first ½ mile (0.8 km) of the park, the stream is confined by a deep gorge, 40 feet (12 m) or more tall, and quickly flattens to a meandering stream through the rest of the park. The present study describes the application of HEC-RAS with the integration of ArcGIS for steady flow analyses ...

The Coastal Monitor: Vol. 1, No. 2, John Tanacredi Ph.D.

Dr. John T. Tanacredi

At a recent event a colleague asked me, “So what do you do at CERCOM?” My immediate response was the “M” word fundamentally! After 45 years involved in environmental sciences, monitoring remains the most important and critical aspect of not only any field station in support of the academics conducted, but the seminal responsibility to be able, as a scientist, to reveal trends in the massive volume of data collected through routine monitoring exercises. It is extremely rare for a single data point, or even a single season of data, no matter how accurate the individual data point is, to ...


Tidal Flat Ecology: An Experimental Approach To Species Interactions By K. Riess, John T. Tanacredi Ph.D. 2018 Molloy College

Tidal Flat Ecology: An Experimental Approach To Species Interactions By K. Riess, John T. Tanacredi Ph.D.

Dr. John T. Tanacredi

A periodic pause to intensely observe a singularly unique ecosystem sharpens one's awareness of this diverse world of ours, especially, as the author notes, if one observes a transitional ecosystem whose ecological treasures are hidden or maybe obscured by a tidal sediment's resemblance to a large, rotten cheese! "It smells, is slimy and sticky, is punched with holes and crowded with various worms." Sounds good to me! Reise's "pause" encompasses 10 years in which he investigated the Wadden Sea mudflats near the border between West Germany and Denmark. He uses this site to discuss the biotic and ...

There is something enchanting and vibrant about viewing the coast. Every day at CERCOM we are welcomed by either a vivid sunrise, a view of the barrier island Fire Island and a blending of the sky across the horizon, ultimately flooding the Great South Bay with either clouds or sunshine that reveals the Bay’s surface as either shimmering with sunlight, or an integration of sky and water as an endless ocean. I don’t normally wax poetic but the varying sights along the near shore ocean and this embayment beckon our scientific inquisitiveness. What’s below the surface water ...

Water Quality Characterization And Mathematical Modeling Of Dissolved Oxygen In The East And West Ponds, Jamaica Bay Wildlife Refuge, John Tanacredi Ph.D., D Roy, Krishnanand Maillacheruvu 2018 Molloy College

Water Quality Characterization And Mathematical Modeling Of Dissolved Oxygen In The East And West Ponds, Jamaica Bay Wildlife Refuge, John Tanacredi Ph.D., D Roy, Krishnanand Maillacheruvu

Dr. John T. Tanacredi

The current study was undertaken to characterize the East and West Ponds and develop a mathematical model of the effects of nutrient and BOD loading on dissolved oxygen (DO) concentrations in these ponds. The model predicted that both ponds will recover adequately given the average expected range of nutrient and BOD loading due to waste from surface runoff and migratory birds. The predicted dissolved oxygen levels in both ponds were greater than 5.0 mg/L, and were supported by DO levels in the field which were typically above 5.0 mg/L during the period of this study. The ...

Each fall I teach a course in “Ecology” and in the spring, “Marine Biology”; two seminal courses absolutely necessary and required to complete a BS Degree in Earth and Environmental Studies at Molloy College. To a large extent I draw on my 48 years of life experiences; flight meteorologist, “Hurricane Hunter” in the US Navy (1968-1970), environmental impact analyst with the US Coast Guard’s Bridge Administration on Governors Island (1974-1978); Coastal Barrier Parks Coordinator and Research Ecologist with the National Park Service (1978-2001); Research Associate in the Invertebrate Zoology Department at the American Museum of Natural History(1982-2000); Chairman ...


Variability In Growth And Age Structure Among Populations Of Ribbed Mussels, Geukensia Demissa (Dillwyn) (Bivalvia: Mytilidae), In Jamacia Bay, New York (Gateway Nra), John Tanacredi Ph.D., David R. Franz 2018 Molloy College

Variability In Growth And Age Structure Among Populations Of Ribbed Mussels, Geukensia Demissa (Dillwyn) (Bivalvia: Mytilidae), In Jamacia Bay, New York (Gateway Nra), John Tanacredi Ph.D., David R. Franz

Dr. John T. Tanacredi

Growth rates, body weight, density and biomass of ribbed mussels, Geukensia demissa (Dillwyn), were determined at Spartina alterniflora marsh-flat sites in Jamaica Bay, New York (Lower Hudson Estuary). Cumulative growth and annual growth increments varied but rates were lower at sites within the central bay relative to peripheral sites. Local variability both in size at Ring-1 and size-specific annual growth rates probably account for the variability in cumulative length. No pattersn were noted in frequency distributions of shell size but congruence in age structure was observed among neighboring sites in some areas of the bay. Mussel densities were greater within ...


Questioning Ecosystem Assessment And Restoration Practices In A Major Urban Estuary: Perpetuating Myths Of Degradation In Spite Of Facts, John T. Tanacredi Ph.D., Martin P. Schreibman, Kevin McDonnell 2018 Molloy College

Questioning Ecosystem Assessment And Restoration Practices In A Major Urban Estuary: Perpetuating Myths Of Degradation In Spite Of Facts, John T. Tanacredi Ph.D., Martin P. Schreibman, Kevin Mcdonnell

Dr. John T. Tanacredi

The Jamaica Bay ecosystem is a dichotomy. It encompasses more than 12,000 acres of coastal estuarine marshes and an ecological diversity rivaling any coastal environment in the world. It is considerably altered, and is affected by a variety of ecological insults directly related to the fact that more than 14 million people live in its vicinity. Environmental protection institutions responded to the challenge of protecting the bay, surrounding wetlands and recreational benefits by addressing the increasing load of contaminants into the ecosystem. Billions of dollars have been spent during the past five decades on restoration attempts, including upgrading wastewater ...

Floyd Bennett Field (FBF), 579 ha in extent, is a division of Gateway National Recreation Area. It is the site of a former airfield, constructed by filling salt marshes with dredged materials. Except for the portion known locally as the “North Forty,” all sections of FBF have been cut over to maintain low vegetation. A grassland management plan (GRAMP) for 165 ha was initiated in 1986, to maintain habitats for open-country birds. Over the next few years, encroaching woody vegetation was removed manually and mechanically from the management area. Since then, it has been maintained as a grassland and receives ...
