Environmental Indicator Report: Water Quality, Phil Trowbridge

PREP Reports & Publications

During the fall and winter of 2001-2002, the New Hampshire Estuaries Project’s Technical Advisory Committee (TAC) developed a suite of environmental indicators to track progress toward the NHEP’s management goals and objectives. These indicators were fully described in terms of their performance criteria, statistical methods, and measurable goals in the NHEP’s Monitoring Plan published in May 2002. The next step is to use these indicators to produce an updated “State of the Estuaries” report by the spring of 2003. The TAC decided to break this task into three sections: shellfish indicators in the fall of 2002; water quality indicators in …

Juvenile Clam Mortality Study At Three Intertidal Flats In Hampton Harbor, New Hampshire, Brian F. Beal

PREP Reports & Publications

Soft-shell clams, Mya arenaria L., represent an important recreational fishery along the New Hampshire coast. Intertidal flats in the Hampton-Seabrook Estuary are among the most heavily harvested. As recently as the fall of 1998, the sandy flats in this area supported more than 900 clammers, who, on weekends, easily harvested their 9.5-liter limit (Varney, 1999). Recently, however, quantitative benthic surveys have suggested that the abundance of adult clams (> 50 mm shell length, SL) has dwindled on the three estuarine flats (Brown’s Flat, Common Island, and Middle Ground). Clammers support this contention and many have been disappointed at the relative …

On The Effect Of Random Errors In Gridded Bathymetric Compilations, Martin Jakobsson, Brian R. Calder, Larry A. Mayer

Center for Coastal and Ocean Mapping

We address the problem of compiling bathymetric data sets with heterogeneous coverage and a range of data measurement accuracies. To generate a regularly spaced grid, we are obliged to interpolate sparse data; our objective here is to augment this product with an estimate of confidence in the interpolated bathymetry based on our knowledge of the component of random error in the bathymetric source data. Using a direct simulation Monte Carlo method, we utilize data from the International Bathymetric Chart of the Arctic Ocean database to develop a suitable methodology for assessment of the standard deviations of depths in the interpolated …

Compressible Kelvin-Helmholtz Instability At The Terrestrial Magnetopause, Alejandro G. Gonzalez, Julio Gratton, Fausto T. Gratton, Charlie J. Farrugia

Coronal Mass Ejection Research Group

The compressible magnetohydrodynamic Kelvin-Helmholtz instability occurs in two varieties, one that can be called incompressible as it exists in the limit of vanishing compressibility (primary instability), while the other exists only when compressibility is included in the model (secondary instability). In previous work we developed techniques to investigate the stability of a surface of discontinuity between two different uniform ows. Our treatment includes arbitrary jumps of the velocity and magnetic fields as well as of density and temperature, with no restriction on the wave vector of the modes. Then it allows stability analyses of complex configurations not previously studied in …

Combining Remote Sensing And Ground Census Data To Develop New Maps Of The Distribution Of Rice Agriculture In China, Steve Frolking, Jianjun Qiu, Stephen Boles, Xiangming Xiao, Jiyuan Liu, Yahui Zhuang, Changsheng Li, Xiaoguang Qin

Earth Sciences

Large-scale assessments of the potential for food production and its impact on biogeochemical cycling require the best possible information on the distribution of cropland. This information can come from ground-based agricultural census data sets and/or spaceborne remote sensing products, both with strengths and weaknesses. Official cropland statistics for China contain much information on the distribution of crop types, but are known to significantly underestimate total cropland areas and are generally at coarse spatial resolution. Remote sensing products can provide moderate to fine spatial resolution estimates of cropland location and extent, but supply little information on crop type or management. We …

Detecting And Predicting Spatial And Interannual Patterns Of Temperate Forest Springtime Phenology In The Eastern U.S., J P. Jenkins, Rob Braswell, Steve Frolking, John Aber

Earth Sciences

We performed a diagnostic analysis of AVHRR-NDVI and gridded, temperature data for the deciduous forests of the eastern U.S., calibrating temperature accumulation model with satellite data for 1982–1993. The model predicts interannual variability in onset date based upon year-to-year changes in springtime temperature. RMS error over the period ranges from 6.9 days in the northern portion of the domain to 10.7 days in the south. The analysis revealed a relationship between temperature accumulation and satellite derived onset date (rank correlation = 0.31–0.62). The required temperature accumulation threshold can be expressed as a function of mean temperature (R² of 0.90) …

U.S. East Coast Trough Indices At 500 Hpa And New England Winter Climate Variability, James A. Bradbury, Barry D. Keim, Cameron P. Wake

Earth Sciences

Using monthly gridded 500-hPa data, two synoptic indices are defined to better understand the principle mechanisms controlling intraseasonal to multiannual winter climate variability in NewEngland (NE). The “trough axis index” (TAI) is created to quantify the mean longitudinal position of the common East Coast pressure trough, and the “trough intensity index” (TII) is calculated to estimate the relative amplitude of this trough at 42.5°N. The TAI and TII are then compared with records for NE regional winter precipitation, temperature, and snowfall with the goal of understanding physical mechanisms linking NE winter climate with regional sea surface temperatures (SST), the North …

Automatic Estimation Of The Seafloor Geomorphology Of The Santos Basin, Brazil, Brian R. Calder, Luciano E. Fonseca, Joao B. Francolin

Center for Coastal and Ocean Mapping

The bathymetry and acoustic backscatter of Santos Basin, Brazil were mapped using a SeaBeam 2112 (12 kHz, 151 beam) Multibeam Echosounder (MBES) aboard the R/V Falcon Explorer. This MBES data was acquired from January-November, 2000, during a high-resolution multi-channel 3D seismic survey, resulting in 380 parallel lines of 90 km length, spaced 250 m apart. The final survey mapped an area of 5,000 km${}^2$ in water depths of 900--2000 m. These closely spaced multibeam tracks resulted in an average overlap between swaths of 1000%, thereby ensonifying most areas of the seafloor at least ten times. Traditional (hand) processing of a …

Developing Impervious Surface Estimates For Coastal New Hampshire, David G. Justice, Fay A. Rubin

PREP Reports & Publications

Future population growth and the corresponding increase in development in the coastal zone of NH are widely recognized as major threats to the integrity of coastal systems and their watersheds. The potential impacts associated with the expansion of developed land, and specifically with increasing amounts of impervious surfaces – rooftops, sidewalks, roads, and parking lots - may include significant changes in water quantity, degradation in water quality, and habitat loss. Because asphalt, concrete, stone, and other impenetrable materials effectively seal the ground surface, water is repelled and is prevented from infiltrating soils. Instead, stormwater runoff flows directly into our surface …

Saving Special Places: Community Funding For Land Conservation, Brian Hart, Dorothy Tripp Taylor

PREP Reports & Publications

In New Hampshire communities, there is a groundswell of interest and activity in conserving land. New Hampshire currently has more than forty-five land trusts. There are conservation commissions in all but a handful of towns. Many of them are engaged in conserving their special natural lands. Over half of the towns in the state have conservation funds fueled by the Land Use Change Tax. There have been 62 applications for land conservation projects to the Land and Community Heritage Investment Program since its inception in 2000. New Hampshire voters are appropriating significant taxpayer funds to conserve undeveloped land. Twelve communities, …
