Net samples of live zooplankton were collected from Fishers Island Sound in mid December 1984 for the purpose of determining the mortality due to net capture and the short-term effect on organism survival of high population densities in an artificial environment. The contents of two series of five net tows each were placed in two separate insulated coolers containing 30 liters each of filtered sample-site water. The resultant concentrations in ...

Environmental Impact Research Program. Ecological Effects of Rubble- Mound Breakwater Construction and Channel Dredging at West Harbor, Ohio (Western Lake Erie)

SEP 85

Authors: Bruce A. Manny; Donald W. Schloesser; Charles L. Brown; John R. P. French III; ARMY ENGINEER WATERWAYS EXPERIMENT STATION VICKSBURG MS ENVIRONMENTAL LAB

The investigation indicated that breakwater construction and associated channel dredging activities by the US Army Corps of Engineers in western Lake Erie at the entrance to West Harbor (Ohio) had no detectable adverse impacts on the distributions or abundances of macrozoobenthos and fishes. Rather, increases were noted in the number of fish eggs and larvae and in the desnity and biomass of periphyton and macrozoobenthos on and near the breakwaters. ...

Experimental Studies of the Survival of Zooplankton: Effects of Net Capture and Artificial Control of Population Densities

27 AUG 85

Authors: Albert L. Brooks; Charles L. Brown; NAVAL UNDERWATER SYSTEMS CENTER NEW LONDON CT NEW LONDON LAB

Field and laboratory experiments were performed to determine the effects of capture, transportation and various conditions of crowding in an artificial environment on the survival of zooplanktonic organisms. Mortality due to net capture was estimated to be 36 percent. Results indicate that this mortality can be significantly reduced by (1) using a net with a large mouth diameter (e.g., 1 meter), (2) restricting duration of each net tow to 4-5 ...

Particle Sampling and Analysis in Dabob Bay, Washington

13 SEP 1982

Authors: Charles L. Brown; NAVAL UNDERWATER SYSTEMS CENTER NEW LONDON CT NEW LONDON LAB

The concentration of particles in the water column was correlated with turbulence in the boundary layer of experimental underwater vehicle B-1 in Dabob Bay, Washington, in 1979. With the advent of field testing of experimental vehicle LDV-2 in the same location, a more comprehensive particle sampling program was implemented in 1980. From samplings taken from August through December 1980, the average total number of particles in the size range 50 ...

Ocean Acre Final Report: A Comparison of Volume Scattering Prediction Models,

23 DEC 1977

Authors: Albert L. Brooks; Charles L. Brown; NAVAL UNDERWATER SYSTEMS CENTER NEW LONDON CONN NEW LONDON LAB

Vertical profiles of scattering strength were successfully predicted for an ocean area off Bermuda from net trawl data on the vertical population density of 55 species of airbladdered, midwater fish collected during different years and seasons. The final predicted profiles compare favorably in shape and magnitude with measured profiles of scattering strength at 3.85, 5.0, 7.0, 9.0, and 15.5 kHz. At 3.85 kHz, only one of the predicted scattering strength ...

Hydraulic and Lubricating Oil Composition.

18 MAR 1975

Authors: Charles L. Brown; DEPARTMENT OF THE NAVY WASHINGTON D C

Conventional hydraulic fluids and lubricating oils permit corrosion of metal surfaces in the presence of water. Certain oils used by industry and the military have inhibitors which are designed to provide rust protection but even these have some shortcomings. This invention provides a hydraulic and lubricating oil composition which prevents corrosion of metal surfaces which are exposed to fresh water or sea water. This is accomplished by providing a composition ...

Ocean Acre 11: A Report of the Cruise with Some Preliminary Observations.

06 APR 1971

Authors: Charles L. Brown; NAVAL UNDERWATER SYSTEMS CENTER NEWPORT R I

The eleventh Ocean Acre Cruise occurred between 9-22 January 1971, aboard USNS SANDS (T-AGOR-6). The objectives of the cruise were to: continue seasonal collections of biological organisms throughout the water column to a depth of 1500 meters, take measurements of scattering strengths of the water column at three frequencies (3.85, 13.5 and 15.5 kHz), and take associated hydrographical data. The information obtained is part of the Ocean Acre program designed ...
