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 …

Sea Surface Salinity Measurements In The Historical Database, Frederick M. Bingham, Stephan D. Howden, Chester J. Koblinsky

Faculty Publications

We have examined historical distributions of sea surface salinity (SSS) observations in a data set consisting of a combination of the World Ocean Database 1998 (WOD98) and a thermosalinograph and bucket salinity database collected from volunteer observing ships. It is well known that SSS in much of the world's ocean is measured infrequently or not at all. We find that 27% of one-degree squares in the world ocean (open and coastal, excluding the Arctic Ocean) had no observations of SSS in the historical database, and 70% had 10 or fewer. Systematic sampling of SSS (more than 10,000 observations per year …

Surface And Deep Ocean Circulation In The Subpolar North Atlantic During The Mid-Pleistocene Revolution, Amy K. Wright, Benjamin P. Flower

Marine Science Faculty Publications

We investigated surface and deep ocean variability in the subpolar North Atlantic from 1000 to 500 thousand years ago (ka) based on two Ocean Drilling Program (ODP) sites, Feni drift site 980 (55°29′N, 14°42′W) and Bjorn drift site 984 (61°25′N, 24°04′W). Benthic foraminiferal stable isotope data, planktic foraminiferal faunas, ice‐rafted debris data, and faunally based sea‐surface temperature estimates help test the hypothesis that oceanographic changes in the North Atlantic region were associated with the onset of the 100‐kyr world during the mid‐Pleistocene revolution. Based on percentage of Neogloboquadrina pachyderma (s) records from both sites, surface waters during interglacials and glacials …

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, …

An Examination Of Predatory Pressures On Piping Plovers Nesting At Breezy Point, New York, Brook Lauro, John Tanacredi Ph.D.

Faculty Works: CERCOM

This study examines predatory threats to Piping Plovers (Charadrius melodus) nesting at Breezy Point, Gateway National Recreation Area, New York. Several methods used include: 1) an evaluation of reproductive success data with documentation of predation to eggs and chicks, 2) predator surveys, and 3) an artificial nest study. The range of breeding pairs nesting from 1988-1996 was 11-19, with an average of 15.8 (SE ± 0.79) pairs/season. The average number of eggs hatched and chicks fledged per year for pairs was 2.2 ± 0.23 and 0.8 ± 0.16 respectively. Reasons for egg losses often went undetected (68%) but …

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 …

Long-Distance Dispersal Potential In A Marine Macrophyte, Mc Harwell, R J. Orth

VIMS Articles

Plant populations have long been noted to migrate faster than predicted based on their life history and seed dispersal characteristics (i.e., Reid's paradox of rapid plant migration). Although precise mechanisms to account for such phenomena are not fully known for all plant species, a combination of theoretical and empirically driven mechanisms often resolves this paradox. Here, we couple a series of direct and indirect field and laboratory exercises on one marine macrophyte, Zostera marina L. (eelgrass), to measured distances between new patches and established beds in order to elucidate the longdistance dispersal and colonization potential of this marine seagrass. Detached, …

A Multiproxy Approach To Reconstructing Sea Surface Conditions Using Coral Skeleton Geochemistry, Terrence M. Quinn, Daniel E. Sampson

Marine Science Faculty Publications

[1] We use elemental ratio (Mg/Ca, Sr/Ca, U/Ca and Ba/Ca) and oxygen isotope data from a Porites lutea coral head collected from offshore Amedee Island, New Caledonia (22degrees29'S, 166degrees28'E) to assess the degree to which changes in these geochemical variables reflect variations in sea surface conditions. We have assessed the robustness of each geochemical proxy by comparing 25 years (1992-1968) of monthly geochemical variations with a local record of sea surface temperature (SST) and with the appropriate 1degrees by 1degrees grid box from a global gridded SST data set. We conclude from our comparison that the most consistent proxies of …

A Perspective On Two Decades Of Policies And Regulations Influencing The Protection And Restoration Of Submerged Aquatic Vegetation In Chesapeake Bay, Usa, R J. Orth, Ra Batiuk, Pw Bergstrom, Ken Moore

VIMS Articles

Seagrasses along with many other species of freshwater rooted submerged macrophytes in Chesapeake Bay (collectively called SAV) underwent serious declines in population abundances in the 1970s and have not as yet rebounded to previous levels. Cooperative efforts by scientists, politicians, federal and state resource managers, and the general public have developed policies and plans to protect, preserve and enhance SAV populations of Chesapeake Bay. These include the Chesapeake Bay Agreements (1983, 1987, 1992, 1993, 2000), an SAV Management Policy and Implementation Plan for Chesapeake Bay and Tidal Tributaries (1989 and 1990), Chesapeake Bay Blue Crab Fishery Management Plan (1997), as …

The Magnitude Of Spring Bacterial Production In The North Atlantic Ocean, Hw Ducklow, Dl Kirchman, Tr Anderson

VIMS Articles

Dissolved organic carbon (DOC), a major reservoir in the ocean carbon cycle, is produced by a profusion of plankton sources and processes but is consumed mainly by bacterioplankton. Thus bacterial metabolism regulates the entry of DOC into the longer scale global carbon cycle. Bacterial production (BP) is the routinely measured quantity for evaluating the roles of bacteria in carbon cycling. However BP cannot be measured directly and instead is estimated from related metabolic processes requiring the use of poorly constrained conversion factors. BP and thus the total carbon utilization, are potentially uncertain by a factor of two or more. In …

Mrnas Located In Squalus Acanthias (Spiny Dogfish) Oligodendrocyte Processes, Nicholas Pahl, Sara Homsi, Hilary G. Morrison, Robert M. Gould

Ocean Engineering and Marine Sciences Faculty Publications

This study identifies mRNAs located in oligodendrocyte (OL) processes of spiny dogfish and compares them with mRNAs that were previously identified in rat OL processes (1, 2). Because these two species have independent evolutionary histories covering hundreds of millions of years, mRNAs common to OL processes in both species likely represent proteins recruited to form the original myelin sheaths in the common gnathostome ancestor. Of the mRNAs present in rat OL processes, myelin basic protein (MBP) and myelin-associated oligodendrocytic basic protein (MOBP) mRNAs dominate (1, 2). Surprisingly, however, MBP mRNA is not located in spiny dogfish OL processes; rather it …
