Ground water discharge and the related nutrient and trace metal fluxes into Quincy bay, Massachusetts Ground water discharge and the related nutrient and trace metal fluxes into Quincy bay, Massachusetts
Measurement of the rate and direction of ground water flow beneath Wollaston Beach, Quincy, Massachusetts by use of a heat-pulsing flowmeter shows a mean velocity in the bulk sediment of 40 cm d−1. The estimated total discharge of ground water into Quincy Bay during October 1990 was 1324–2177 m3 d−1, a relatively low ground water discharge rate. The tides have only a moderate effect on...

Seismic experiment ross ice shelf 1990/91: Characteristics of the seismic reflection data Seismic experiment ross ice shelf 1990/91: Characteristics of the seismic reflection data
The Transantarctic Mountains, with a length of 3000-3500 km and elevations of up to 4500 m, are one of the major Cenozoic mountain ranges in the world and are by far the most striking example of rift-shoulder mountains. Over the 1990-1991 austral summer Seismic Experiment Ross Ice Shelf (SERIS) was carried out across the Transantarctic Mountain front, between latitudes 82 degrees to 83...
Geodetic airborne laser altimetry of Breidamerkurjökull and Skeidarárjökull, Iceland, and Jakobshavns Isbræ, West Greenland Geodetic airborne laser altimetry of Breidamerkurjökull and Skeidarárjökull, Iceland, and Jakobshavns Isbræ, West Greenland
Two geodetic airborne laser altimeter (ALA) systems coupled to Global Positioning System receivers acquired submeter-resolution topographic profiles of the lower parts of Breidamerkurjökull and Skeidarárjökull, Iceland, in May 1989 and September 1991 (Skeidarárjökull) and of Jakobshavns Isbræ, Greenland, in April 1992. Maximum measured crevasse depths on Breidamerkurjökull...

Modelling passive margin sequence stratigraphy Modelling passive margin sequence stratigraphy
We have modelled stratigraphic sequences to aid in deciphering the sedimentary response to sea-level change. Sequence geometry is found to be most sensitive to sea level, but other factors, including subsidence rate and sediment supply, can produce similar changes. Sediment loading and compaction also play a major role in generating accommodation, a factor often neglected in sequence...

Evaluation of a bypass system for spent American shad at Holyoke Dam, Massachusetts Evaluation of a bypass system for spent American shad at Holyoke Dam, Massachusetts
A bypass system for postspawned American shad Alosa sapidissima began operation in 1980 on the Connecticut River canal system at Holyoke Dam. The purpose of the bypass was to enable downstream migrants that enter the canal to exit and avoid death due to delay or passage through hydroelectric turbines at water use facilities. The bypass system had the following elements: (1) an underwater...
