Oyster Reef Restoration Project For The City Of Dover, Grizzle, Raymond E. Grizzle, Jennifer Greene, Holly Abeels Jul 2006

Oyster Reef Restoration Project For The City Of Dover, Grizzle, Raymond E. Grizzle, Jennifer Greene, Holly Abeels

PREP Reports & Publications

This project was conducted as a contract between the City of Dover and the University of New Hampshire, with additional funding supplied by the New Hampshire Estuaries Project. The overall goal was to restore as much bottom area as possible (with available funds) of formerly productive oyster bottom in two areas, the Bellamy River and Pomeroy Cove (Piscataqua River). The restored areas were intended as a contribution to the long-term NHEP goal of restoring 20 acres of oyster bottom by 2010 (Trowbridge 2003). Five objectives were addressed: (1) site surveys, map production, and final restoration protocol development; (2) remote setting …

Development And Monitoring Of Revegetation Methods: Connecting Students With Restoration Activities At Awcomin Marsh, David M. Burdick, Christopher R. Peter, Kirsten A. Nelson Jul 2006

Development And Monitoring Of Revegetation Methods: Connecting Students With Restoration Activities At Awcomin Marsh, David M. Burdick, Christopher R. Peter, Kirsten A. Nelson

PREP Reports & Publications

Five classes in a local elementary school participated in an effort to grow and plant high marsh and upper border vegetation at a salt marsh restoration site in spring 2005. Seeds of six marsh upper edge species were successfully germinated and grown into seedlings by third graders. The seedlings were planted by the students in late spring 2005, but only switchgrass and quackgrass plants appeared to have established and survived after one year. Mature shoots of three high marsh species planted by the third graders (salt hay, salt grass and black grass) established successfully and continue to proliferate. In addition, …

Testing Of Great Bay Oysters For Two Protozoan Pathogens, John I. Nelson Jul 2006

Testing Of Great Bay Oysters For Two Protozoan Pathogens, John I. Nelson

PREP Reports & Publications

Two protozoan pathogens, Haplosporidium nelsoni (MSX) and Perkinsus marinus(Dermo) are known to be present in Great Bay oysters. With funds provided by the New Hampshire Estuaries Project (NHEP), the Marine Fisheries Division of New Hampshire Fish and Game Department, (NHF&G) continues to assess the presence and intensity of both disease conditions in oysters from the major beds, some open for harvest, within the Great Bay estuarine system. Histological examination of Great Bay oysters has also revealed other endoparasites.

Spatial Patterns Of Marine Larvae As Indicators Of Incipient Invasions In Great Bay, James E. Byers, Blaine Griffen Jul 2006

Spatial Patterns Of Marine Larvae As Indicators Of Incipient Invasions In Great Bay, James E. Byers, Blaine Griffen

PREP Reports & Publications

Understanding the dynamics of coastal marine communities represents a substantial challenge, and one that is actively pursued globally. Within the United States, several sites have been designated as National Estuarine Research Reserves (NERR) with the idea that concentrated research at these sites will lead to greater understanding of the ecosystem. The Great Bay Estuary of New Hampshire is one of these sites. A wide spectrum of research is conducted within the Great Bay, and substantial financial support is committed to that research on an annual basis. To facilitate the success of these research efforts, it is particularly important to develop …

Eelgrass Distribution In The Great Bay Estuary 2004, Frederick T. Short Jun 2006

Eelgrass Distribution In The Great Bay Estuary 2004, Frederick T. Short

PREP Reports & Publications

Eelgrass (Zostera marina) is an essential habitat for the Great Bay Estuary (GBE) because it provides food for wintering waterfowl and habitat for juvenile fish and shellfish. Eelgrass is the basis of an estuarine food chain that supports many of the recreationally, commercially and ecologically important species in the estuary. Additionally, eelgrass filters estuarine waters, removing both nutrients and suspended sediments from the water column. Eelgrass in the Great Bay Estuary is the largest monoculture in the State of New Hampshire and is considered a vital resource to the State’s marine environment. The UNH Seagrass Ecology Group has mapped the …

Water Reuse Feasibility Study, City Of Portsmouth Jun 2006

Water Reuse Feasibility Study, City Of Portsmouth

PREP Reports & Publications

The use of reclaimed water in the southern and western parts of the United States has been common practice for over 40 years. These water short areas have realized the value of utilizing highly treated wastewater (reclaimed water) and consider it a resource rather than a disposal problem. Growth impacts on drinking water supplies in New England, and specifically in Portsmouth, have now brought this concept to New Hampshire. Currently the Pease Golf Course is using approximately 200,000 to 300,000 gallons per day (gpd) of potable water for irrigation in the summer months. The City of Portsmouth supplies this potable …

Impervious Surface Mapping In Coastal New Hampshire (2005), David G. Justice, Fay A. Rubin Apr 2006

Impervious Surface Mapping In Coastal New Hampshire (2005), David G. Justice, Fay A. Rubin

PREP Reports & Publications

Estimates of impervious surface acreage in 2005 were generated and compared to prior estimates for 1990 and 2000 for a 48-town region in coastal New Hampshire, including the 42 towns within Zones A and B of the New Hampshire Estuaries Project (NHEP) area. The estimates were based on applying both traditional and subpixel image classification techniques to 30-meter Landsat 5 Thematic Mapper (TM) satellite data, acquired 3 October 2005. The classifications indicated that impervious surface acreage increased from 4.3% (31,233 acres) in 1990, to 6.3% (45,445 acres) in 2000, to 7.4% (53,408 acres) in 2005.

2005 Great Bay Organic Nitrogen (Pon & Don) And Light Extinction (Par) Monitoring Program, Jonathan Pennock Mar 2006

2005 Great Bay Organic Nitrogen (Pon & Don) And Light Extinction (Par) Monitoring Program, Jonathan Pennock

PREP Reports & Publications

Nitrogen is most often considered to be the limiting nutrient for plant growth in marine waters. As a result, knowledge of nitrogen loading and ambient water-column concentrations are considered to be critical to understanding the response of aquatic ecosystems to nutrient over-enrichment—a process known as eutrophication when it results in the excess production of organic matter. Plant production in many estuarine systems may also be limited by light availability as a result of high levels of turbidity in the water resulting from sediments, dissolved organic matter, and phytoplankton in the water column. Light limitation resulting from human-induced increases in turbidity …

PREP Reports & Publications

A series of field experiments to assess the efficacy of enhancing intertidal areas with cultured clam (Mya arenaria L.) seed (mean shell length [SL] = 7-10 mm) was conducted at Willows Flat, Hampton, New Hampshire from November 2004 to May 2005 and from June - October 2005. The first trial examined the interactive effects of size of planting area (4, 8, 12, 18 m2) and predator deterrent netting (none, 4.2 mm, and 6.4 mm aperture [flexible, plastic netting]) on clam growth and survival at one intertidal location. The second trial examined the effect of predator deterrent netting on clam growth …
