Verification of a model for predicting the effect of inconstant temperature on embryonic development of lake whitefish (Coregonus clupeaformis)
William H. Berlin, L.T. Brooke, Linda J. Stone
1977, Technical Paper 92
Eggs stripped from lake whitefish (Coregonus clupeaformis) spawning in Lake Michigan were incubated in the laboratory at temperatures similar to those on whitefish spawning grounds in Lake Michigan during December-April. Observed times from fertilization to attainment of each of 21 developmental stages were used to test a model that predicts...

The two study areas are separated...
Correlation of major eastern earthquake centers with mafic/ultramafic basement masses
Martin Francis Kane
1977, Open-File Report 77-134
Extensive gravity highs and associated magnetic anomalies are present in or near seven major eastern North American earthquake areas as defined by Hadley and Devine (1974). The seven include the five largest of the eastern North American earthquake .centers. The immediate localities of the gravity anomalies are, however, relatively free...
Nitrogen in water in Nassau and Suffolk counties, Long Island, New York, in 1971
Brian G. Katz, Stephen E. Ragone, C. Albert Harr
1977, Open-File Report 77-433
The concentration of inorganic nitrogen was measured in samples from 521 wells in the upper glacial and Magothy aquifers and from 46 streams in Nassau and Suffolk Counties during May 1971. The predominant form of dissolved nitrogen was nitrate. Nitrate concentrations (as N) in the upper glacial aquifer in both...
