PREP Reports & Publications
The overall goal of the project was to make a significant contribution to the Piscataqua Region Estuaries Partnership goal of increasing oyster (Crassostrea virginica) bottom in New Hampshire, and to do so using methods that positively affect multiple species. The focus was on those organisms (mainly macroalgae, invertebrates, and fish) that spend most of their time on oyster reefs—the resident species. A 0.5 hectare (1.25 acres) area was restored in August 2007 by constructing twelve mini-reefs (each ~6 m in diameter) in an area protected from harvest using spat-on-shell (“spat seeding”) from remotely set larvae. There was a consistent trend …

Eelgrass Distribution In The Great Bay Estuary For 2008, Frederick T. Short
Eelgrass Distribution In The Great Bay Estuary For 2008, Frederick T. Short
PREP Reports & Publications
Eelgrass in the Great Bay Estuary in 2008 was found only in the Great Bay itself and Portsmouth Harbor. In 2008 there was a continued loss of eelgrass biomass in the Estuary. Virtually all the eelgrass in Little Bay and the Piscataqua River has died. Eelgrass in Great Bay itself experienced an increase in distribution from 2007 to 2008, primarily from the re-seeding of bare areas that had been de-vegetated by nuisance algae in previous years. However, Great Bay showed a decrease in eelgrass biomass in 2008. Portsmouth and Little Harbors experienced a slight decrease in both distribution and cover …

Nitrogen, Phosphorus, And Suspended Solids Concentrations In Tributaries To The Great Bay Estuary Watershed In 2008, Philip Trowbridge
PREP Reports & Publications
Nitrogen, phosphorus, and sediment loads to the Great Bay Estuary are a growing concern. In the 2006 State of the Estuaries report (NHEP, 2006), the New Hampshire Estuaries Project (now called the Piscataqua Region Estuaries Partnership or PREP) calculated the nitrogen load from tributaries to the Great Bay Estuary using data collected by the NH Department of Environmental Services. PREP needs to update this indicator for the 2009 State of the Estuaries report. Therefore, the purpose of this study was to collect representative data on nitrogen, phosphorus, and suspended sediment concentrations in tributaries to the Great Bay Estuary in 2008. …

Eelgrass Mapping Great Bay Estuary For 1981, Frederick T. Short
Eelgrass Mapping Great Bay Estuary For 1981, Frederick T. Short
PREP Reports & Publications
The methods for this project followed the procedures specified in the approved QA Project Plan (Short and Trowbridge, 2003). Eelgrass meadow polygons for 1981 were mapped from USDA black-and-white aerial photographs, on file at the Strafford County and Rockingham County (NH) offices. The photographs were scanned and analyzed digitally after “rubber sheeting” the images to fit the Great Bay Estuary base map. The 1981 photographs were not ortho-photographs and some distortion across each photograph was evident. To minimize this effect, multiple photographs for each area were used to geo-reference actual locations on the eelgrass distribution map. Some areas of the …

Biological Sciences
The recovery of benthic communities inside the western Gulf of Maine fishing closure area was evaluated by comparing invertebrate assemblages at sites inside and outside of the closure four to six years after the closure was established. The major restriction imposed by the closure was a year-round prohibition of bottom gillnets and otter trawls. A total of 163 seafloor sites (similar to half inside and half outside the closure) within a 515-km(2) study area were sampled with some combination of Shipek grab, Wildco box corer, or underwater video. Bottom types ranged from mud (silt and clay) to boulders, and the …

Hampton-Seabrook Estuary Habitat Restoration Compendium, Alyson L. Eberhardt, David M. Burdick
PREP Reports & Publications
The goal of this report is to identify restoration opportunities within the watershed derived from data on habitat change. Many other factors exist that are important in the identification and selection of restoration projects, including water quality and non-point source pollution, water withdrawal, harbor maintenance, recreational impacts, human history, and socioeconomic factors, among others. Although information regarding these factors is not explicitly included in this analysis, these factors must be considered and addressed as they may limit the potential for success in specific restoration efforts
