Dispersal and migratory patterns of San Francisco Bay produced herons, egrets, and terns
Robert E. Gill Jr., L. Richard Mewaldt
1979, North American Bird Bander (4) 4-13
San Francisco Bay, California, including its fringing marshes, supports a large and diverse water related avifauna (Grinnell and Wythe 19271 Sibley 1952, Gill 1973, 1977). Certain of man's alterations of the Bay's shallower wetlands have resulted in increased habitat diversity which has allowed colonization by several species of birds including...
Barometric fluctuations in wells tapping deep unconfined aquifers
Edwin P. Weeks
1979, Water Resources Research (15) 1167-1176
Water levels in wells screened only below the water table in unconfined aquifers fluctuate in response to atmospheric pressure changes. These fluctuations occur because the materials composing the unsaturated zone resist air movement and have capacity to store air with a change in pressure. Consequently, the translation of any pressure...
Improved signal discrimination in tectonomagnetism: Discovery of a volcanomagnetic effect at Kilauea, Hawaii
P.M. Davis, F.D. Stacey, C.J. Zablocki, J.V. Olson
1979, Physics of the Earth and Planetary Interiors (19) 331-336
Cancellation of extraterrestrial magnetic disturbances by taking simple differences between total field readings at spaced stations is imperfect. It is shown that improvement is possible when three component observatory data are available from a single station in the general, but not necessarily immediate, vicinity of an array of total field...

International cooperation in water resources
J.R. Jones, R.M. Beall, E.V. Giusti
1979, GeoJournal (3) 481-487
Advancements in hydrology proceeded slowly until the late 1800's when new ventures created a surge of interest and accomplishment. Progress waned again until the middle 20th century when an International Hydrological Decade was conceived, eventually receiving wide multinational support from governmental agencies and nongovernmental institutions. Organized by UNESCO, the Decade...

The flow mechanism in the Chalk based on radio-isotope analyses of groundwater in the London Basin
R.A. Downing, F.J. Pearson, D. B. Smith
1979, Journal of Hydrology (40) 67-83
14C analyses of groundwaters from the Chalk of the London Basin are re-interpreted and the age of the groundwater is revised. Radio-isotope analyses are used to examine the flow mechanism in the aquifer. The evidence supports the view that a network of micro-fissures and larger intergranular pores in the matrix...
Worth of data and natural disaster insurance
E. D. Attanasi, M.R. Karlinger
1979, Water Resources Research (15) 1763-1766
The Federal Government in the past has provided medical and economic aid to victims of earthquakes and floods. However, regulating the use of hazard-prone areas would probably be more efficient. One way to implement such land use regulation is through the national flood and earthquake insurance program. Because insurance firms...
