Potentiometric surface of the Floridan aquifer, southwest Florida Water Management District, September 1981
D. K. Yobbi, G. R. Schiner
1981, Open-File Report 82-101
A September 1981 potentiometric-surface map of the Southwest Florida Water Management District depicts the annual high water-level period. Water levels in most wells measured in September 1981 are equal to or higher than in May 1981. Levels averaged about 26 feet higher in the southern part of the area and...

The role of nutrient reserves in mallard reproduction
Gary L. Krapu
1981, The Auk (98) 29-38
Mallard (Anas platyrhynchos) populations breeding in temperate North America obtain a significant part of the energy and lipid requirements of reproduction at sites occupied prior to arrival on the breeding grounds. Protein for egg formation, however, is obtained principally from the diet during the nesting period. Both sexes arrive heavy...
Use of 35-mm color aerial photography to acquire mallard sex ratio data

1981, Photogrammetric Engineering and Remote Sensing (47) 823-827
A conventional 35-mm camera equipped with an f2.8 135-mm lens and ASA 64 color film was used to acquire sex ratio data on mallards (Anas platyrhynchos) wintering in the Platte River Valley of south-central Nebraska. Prelight focusing for a distance of 30.5 metres and setting of shutter speed at 1/2000...
Interaction between diapirism and sediment loading at the shelf-slope boundary, northwest Gulf of Mexico
A. R. Trippet
1981, Geo-Marine Letters (1) 111-114
During the last low stand of sea level, rivers and streams drained across the present northwestern Gulf of Mexico continental shelf depositing sediments in several shallow-water deltas near the present shelf-slope boundary. The weight of these wedges of prograded sediments triggered or augmented both subsidence of local depositional basins and...

Exsolution of Ca-clinopyroxene from orthopyroxene aided by deformation
S. H. Kirby, M.A. Etheridge
1981, Physics and Chemistry of Minerals (7) 105-109
Monoclinic calcium-poor shear-transformation lamellae and calcium-rich exsolution lamellae occur parallel to (100) in orthopyroxene. The formation of both structures from an orthopyroxene host involves a shear on (100) parallel to [001], with additional cation exchange in the exsolution case. The shear transformation involves a macroscopic simple shear angle of 13.3??...
