NEW APPLICATIONS IN THE INVERSION OF ACOUSTIC FULL WAVEFORM LOGS - RELATING MODE EXCITATION TO LITHOLOGY.
Frederick L. Paillet, C.H. Cheng, J.A. Meredith
1987, Log Analyst (28) 307-320
Existing techniques for the quantitative interpretation of waveform data have been based on one of two fundamental approaches: (1) simultaneous identification of compressional and shear velocities; and (2) least-squares minimization of the difference between experimental waveforms and synthetic seismograms. Techniques based on the first approach do not always work, and...
Age of tilted reefs, Hawaii
J.G. Moore, J.F. Campbell
1987, Journal of Geophysical Research Solid Earth (92) 2641-2646
Submerged carbonate reefs are preserved as a series of submarine terraces between Molokai and Hawaii along a 200-km span of the southeastern Hawaiian Ridge. Limestones from two of the terraces have been sampled from submersibles and dated radiometrically at 13 and 120 ka. Recognition that the terraces are tilted permits...

Matthew C. Perry
1986, Dissertation Abstracts International (46B) 3291 (abs)
Captive canvasbacks (Aythya valisineria) were maintained ad libitum on five diets during the winters of 1978-79 and 1979-80 to evaluate the effects of varying protein and energy levels on feed intake and condition. Diets were formulated to simulate either a natural diet high in invertebrates or one high in vegetation....
Demography, environmental uncertainty, and the evolution of mate desertion in the snail kite
Steven Beissinger
1986, Ecology (67) 1445-1459
The Snail Kite (Rostrhamus sociabilis), an endangered hawk, has a unique mating system in Florida (Beissinger and Snyder 1987): when food is abundant, males or females desert their mates at nearly equal frequency (ambisexual mate desertion) in the midst of a nesting cycle. I examined the demographic and environmental constraints...
Subspecies of the greater scaup and their names
R.C. Banks
1986, The Wilson Bulletin (98) 433-444
The name Fuligula mariloides Vigors, presently used by many authors for a subspecies of the Greater Scaup, Aythya marila, was originally proposed for the Lesser Scaup, A. afinis, and may not be used in combination with the name marila. The name mariloides has been applied to a population of Greater...

Severe reproductive impacts were found in aquatic birds nesting on irrigation drainwater ponds in the San Joaquin Valley of California. Of 347 nests studied to late incubation or to hatching, 40.6% had at least one dead embryo and 19.6% had at least one embryo or chick with an obvious external...
On the nature of persistence in dendrochronologic records with implications for hydrology
J.M. Landwehr, N.C. Matalas
1986, Journal of Hydrology (86) 239-277
Hydrologic processes are generally held to be persistent and not secularly independent. Impetus for this view was given by Hurst in his work which dealt with properties of the rescaled range of many types of long geophysical records, in particular dendrochronologic records, in addition to hydrologic records. Mandelbrot introduced an...
Archaeology and public perception of a trans-scientific problem; disposal of toxic wastes in the unsaturated zone
Isaac Judah Winograd
1986, Circular 990
Predicting the effects of toxic-waste disposal on the environment over periods of millenia to hundreds of millenia is a transscientific problem; that is, one not fully addressed by quantitative scientific and engineering endeavors. Archaeology is a pertinent adjunct to such predictions in several ways. First, and foremost, archaeological records demonstrate...
