Scaling Ecosystem Services To Reef Development : Effects Of Oyster Density On Nitrogen Removal And Reef Community Structure, M. Lisa Kellogg, Jeffrey C. Cornwell, Michael S. Owens, Mark Luckenbach, Paige G. Ross, Thomas A. Leggett, Jennifer C. Dreyer C. Dreyer, Bowdoin Lusk, Alan Birch, Edward Smith Nov 2014

Scaling Ecosystem Services To Reef Development : Effects Of Oyster Density On Nitrogen Removal And Reef Community Structure, M. Lisa Kellogg, Jeffrey C. Cornwell, Michael S. Owens, Mark Luckenbach, Paige G. Ross, Thomas A. Leggett, Jennifer C. Dreyer C. Dreyer, Bowdoin Lusk, Alan Birch, Edward Smith

Reports

Eighteen native oyster experimental reefs (16-m2 each) were restored using six oyster densities (0, 10, 25, 50, 100 and 250 adult oysters m-2) with three replicates of each density at each of two sites: one subtidal site in Onancock Creek, Virginia and one intertidal site in Hillcrest Oyster Sanctuary within The Nature Conservancy’s Virginia Coast Reserve. A science-based monitoring program explored quantitative relationships between structural and functional characteristics of these restored reefs. Structural parameters examined included oyster abundance, oyster size/biomass, surface shell volume, reef topographic complexity and sediment characteristics. Functional parameters included denitrification rates and macrofaunal abundance and biomass. Data …


Biofiltration Potential Of Ribbed Mussel Populations, Donna Marie Bilkovic, Molly Mitchell Jul 2014

Biofiltration Potential Of Ribbed Mussel Populations, Donna Marie Bilkovic, Molly Mitchell

Reports

Our primary study objective was to characterize the ribbed mussel population and estimate their water processing potential along the York River, Virginia.


Linking Structural And Functional Characteristics Of Restored Oyster Reefs : A Restoration Project In The Virginia Coast Reserve, M. Lisa Kellogg, Jeffrey C. Cornwell, Michael S. Owens, Mark Luckenbach, Paige G. Ross, Bowdoin Lusk Jun 2014

Linking Structural And Functional Characteristics Of Restored Oyster Reefs : A Restoration Project In The Virginia Coast Reserve, M. Lisa Kellogg, Jeffrey C. Cornwell, Michael S. Owens, Mark Luckenbach, Paige G. Ross, Bowdoin Lusk

Reports

Eighteen native oyster reefs (16-m2 each) were restored using six oyster densities (0, 10, 25, 50, 100 and 250 adult oysters m-2) with three replicates of each density at an intertidal site in The Nature Conservancy’s Virginia Coast Reserve. Reef construction was successful and continues to provide a range of oyster biomass densities useful for exploring relationships between oyster reef structural and functional parameters. Between April 2012 and July 2013, a science-based monitoring program explored quantitative relationships between structural and functional characteristics of these restored reefs. Structural parameters examined included oyster abundance, oyster size/biomass, surface shell volume, reef topographic complexity …


A Model For Estimating The Tmdl-Related Benefits Of Oyster Reef Restoration : Harris Creek, Maryland, Usa, M. Lisa Kellogg, Mark Brush, Elizabeth W. North, Younjoo Lee Jun 2014

A Model For Estimating The Tmdl-Related Benefits Of Oyster Reef Restoration : Harris Creek, Maryland, Usa, M. Lisa Kellogg, Mark Brush, Elizabeth W. North, Younjoo Lee

Reports

A user-friendly, web-accessible model has been developed that allows restoration practitioners and resource managers to easily estimate the TMDL-related benefits of oyster reef restoration per unit area, run restoration scenarios in Harris Creek, MD to optimize restoration planning and implementation, and calculate the benefits of the chosen plan. The model is rooted in scientifically defensible data and is readily transferable to systems throughout the Chesapeake Bay and Eastern Shore. The model operates in five vertically well-mixed boxes along the main axis of the creek. Exchanges among creeks are computed using a tidal prism approach and were compared to exchanges provided …


Virginia Game Fish Tagging Program Annual Report 2013, Susanna Musick, Lewis Gillingham May 2014

Virginia Game Fish Tagging Program Annual Report 2013, Susanna Musick, Lewis Gillingham

Reports

Through 2013, the Virginia Game Fish Tagging Program has maintained a 18-year database of records for tagged and recaptured fish. The program is a co- operative project of the Virginia Saltwater Fishing Tournament (under the Virginia Marine Resources Commission-VMRC) and the Virginia Institute of Marine Science (VIMS) of the College of William and Mary (under the VIMS Marine Advisory Program).


Composition, Distribution, And Dynamics Of Intertidal Epibiota On Coastal Defense Structures, Donna Marie Bilkovic, Molly Mitchell Apr 2014

Composition, Distribution, And Dynamics Of Intertidal Epibiota On Coastal Defense Structures, Donna Marie Bilkovic, Molly Mitchell

Reports

Proliferation of artificial structures to protect shorelines has introduced novel habitat to most coastal environments and fragmented natural habitats. These changes can result in disrupted connectivity, habitat homogenization, and altered estuarine landscapes, with uncertain implications for estuarine and marine faunal community structure and function. In estuaries, such as Chesapeake Bay, where soft-bottom habitat dominates and rocky shorelines are rare, the introduction of artificial rocky structure may enhance recruitment of species that are limited by the availability of suitable substrate including native and introduced species (Bilkovic & Mitchell 2013). There is a significant lack of empirical data on the types of …


Virginia Coastal And Ocean Resource Issues, Virginia Institute Of Marine Science Jan 2014

Virginia Coastal And Ocean Resource Issues, Virginia Institute Of Marine Science

Reports

Fisheries, aquaculture and marine recreation in Chesapeake Bay and the coastal ocean are important economic engines adding greatly to the economy of the Commonwealth of Virginia. Virginia’s commercial harvest ranks 3rd largest and 7th in total value nationwide. Research at the Virginia Institute of Marine Science (VIMS) shows that Virginia’s water-dependent resource-based industries, including commercial and recreational fisheries, shellfish aquaculture and recreational boating, annually generate $2.53 billion in sales and approximately $1.25–$1.5 billion in income, supporting over 20,000 jobs. . . .


Thin-Layer Sediment Addition Of Dredge Material For Enhancing Marsh Resilience, Virginia Institute Of Marine Science Jan 2014

Thin-Layer Sediment Addition Of Dredge Material For Enhancing Marsh Resilience, Virginia Institute Of Marine Science

Reports

Building marsh elevations with sediment delivered from nearby dredging projects is a potentially valuable tool for creating, restoring, and maintaining coastal marshes, and may help slow or reverse losses of wetlands due to coastal development and sea-level rise (Woodhouse et al., 1972). . . .
