The IAEG Commission on Landslides and other Mass Movements on Slopes has proposed English and French names for 19 identifiable features of slope movements and for 7 dimensions of those features. The Commission intends to publish this list in other languages and to supplement and revise it from time to...

Deep magma body beneath the summit and rift zones of Kilauea Volcano, Hawaii
Paul T. Delaney, R.S. Fiske, Asta Miklius, Arnold T. Okamura, Maurice K. Sako
1990, Science (247) 1311-1316
A magnitude 7.2 earthquake in 1975 caused the south flank of Kilauea Volcano, Hawaii, to move seaward in response to slippage along a deep fault. Since then, a large part of the volcano's edifice has been adjusting to this perturbation. The summit of Kilauea extended at a rate of 0.26...
Eocene-Oligocene sea-level changes on the New Jersey coastal plain linked to the deep-sea record
Kenneth G. Miller, Dennis V. Kent, Andrew N. Brower, Laurel M. Bybell, Mark D. Feigenson, Richard K. Olsson, Richard Z. Poore
1990, GSA Bulletin (102) 331-339
We use magnetostratigraphy and Sr-isotope stratigraphy to improve stratigraphic control for the Eocene to Oligocene of the New Jersey coastal plain (ACGS4 borehole). Magnetostratigraphy in many cases is complicated in outcrop sections of shallow-water (<200 m paleodepth) sediments by low remanence and weathering; we minimize these problems by analyzing large...
Eocene diatom chert from Adak Island, Alaska
James R. Hein, Hseuh-Wen Yeh, John A. Barron
1990, Journal of Sedimentary Petrology (60) 250-257
Bedded quartz cherts that contain recognizable diatoms are rare in the geologic record and are described here for the first time. The Eocene Andrew Lake Formation on Adak Island, Alaska consists of about 800 m of sedimentary and volcanogenic rocks. Quartz cherts containing diatoms occur in the upper part of...
Doctorate time rising sharply: How long should it take?
William Glen
1990, Eos, Transactions, American Geophysical Union (71) 354-354
The period 1967–1987 saw a 20% increase in the time it takes to complete the doctorate. That figure is based on data provided by the National Research Council from 11 scientific and engineering fields, including the Earth, atmospheric and marine sciences.The median time spent earning the degree rose from 5.4...
Iron sulfide minerals at Cement oil field, Oklahoma: Implications for magnetic detection of oil fields
Richard L. Reynolds, Neil S. Fishman, Richard B. Wanty, Martin B. Goldhaber
1990, GSA Bulletin (102) 368-380
Aeromagnetic anomalies at Cement oil field (Anadarko basin, Oklahoma) have been attributed to authigenic magnetite. The following characteristics of the magnetite, however, indicate that it is contamination introduced by drilling: (1) occurrence as sharp angular blades and as spheres, commonly with metallographic textures typical of industrial alloys and with associated...
Plane-strain shear dislocations moving steadily in linear elastic diffusive solids
J.W. Rudnicki, Evelyn A. Roeloffs
1990, Journal of Applied Mechanics (57) 32-39
This paper derives the stress and pore pressure fields induced by a plane-strain shear (gliding edge) dislocation moving steadily at a constant speed V in a linear elastic, fluid-infiltrated (Biot) solid. Solutions are obtained for the limiting cases in which the plane containing the moving dislocation (y = 0) is...
Thermal regime of permafrost in Alaska and predicted global warming
T.E. Osterkamp, A.H. Lachenbruch
1990, Journal of Cold Regions Engineering (4) 38-42
The mean surface temperature of permafrost in Alaska has warmed locally as much as 4° C during the last century although some areas show little or no indication of a warming or cooling. There is evidence for a recent cooling, since 1983, south of Prudhoe Bay to the Brooks Range....

Simulation of cotton rat population dynamics and response to rodenticide applications in Florida sugarcane
Clay L. Montague, Lynn W. Lefebvre, David G. Decker, Nicholas R. Holler
1990, Ecological Modelling (50) 177-203
Alternative deterministic simulation models were compared to test the management consequences of present uncertainty about the degree of density dependence involved in cotton rat population cycles in southern Florida sugarcane fields. Efficacy of rodenticide applied in different months was explored under six different scenarios of density dependence and independence in...
Effects of benthic flora on arsenic transport
James S. Kuwabara, Cecily C.Y. Chang, Sofie P. Pasilis
1990, Journal of Environmental Engineering (116) 394-409
Chemical and biological interactions involving arsenic (As) and phosphorus (P) appear to affect significantly As transport and distribution in Whitewood Creek, South Dakota. Data (first‐order uptake rate constants, standing crop, and accumulation factors) that can be used to predict As transport have been determined using algae collected in the creek...
Stability analysis of Eulerian-Lagrangian methods for the one-dimensional shallow-water equations
V. Casulli, Ralph T. Cheng
1990, Applied Mathematical Modelling (14) 122-131
In this paper stability and error analyses are discussed for some finite difference methods when applied to the one-dimensional shallow-water equations. Two finite difference formulations, which are based on a combined Eulerian-Lagrangian approach, are discussed. In the first part of this paper the results of numerical analyses for an explicit...
Diagenesis and interstitial-water chemistry at the Peruvian continental margin; major constituents and strontium isotopes
Miriam Kastner, Henry Elderfield, J.B. Martin, Erwin Suess, Keith A. Kvenvolden, Robert E. Garrison
1990, Proceedings of the Ocean Drilling Program: Scientific Results (112) 413-440
Two distinct hydrogeochemical regimes currently dominate the Peruvian continental margin. One, in shallower water (150-450 m) shelf to upper-slope regions, is characterized by interstitial waters with strong positive chloride gradients with depth. The maximum measured value of 1043 mM chloride at Site 680 at ITS corresponds to a degree of...
Hydrocarbons in sediment of the Weddell Sea, Antarctica
Keith A. Kvenvolden, Frances D. Hostettler, Tamara Frank
1990, Proceedings of the Ocean Drilling Program: Scientific Results (113) 199-208
Heavy hydrocarbons (about C15+) are ubiquitous but minor components in sediment from three sites (692, 693, and 694) drilled during Ocean Drilling Program (ODP) Leg 113. This preliminary report is the first to describe the distribution of some of these hydrocarbons in sediment of the Weddell Sea. Samples from Sites...
Hydrocarbon gases in Tertiary and Quaternary sediments offshore Peru; results and comparisons
Keith A. Kvenvolden, Tamara Frank, M. Golan-Bac
1990, Proceedings of the Ocean Drilling Program: Scientific Results (112) 505-515
Hydrocarbon gases (methane, ethane, propane, isobutane, «-butane, ethene, and propene) are present in Tertiary and Quaternary shelf, upper-slope, and lower-slope deposits of the Peruvian continental margin. Methane dominates the composition of the hydrocarbon gas at all 10 sites examined during Ocean Drilling Program (ODP) Leg 112. Generation of methane is...
Hydrothermally derived petroleum: examples from Guaymas Basin, Gulf of California, and Escanaba Trough, northeast Pacific Ocean
Keith A. Kvenvolden, B.R. Simoneit
1990, AAPG Bulletin (74) 223-237
In the Guaymas Basin, a spreading axis in the Gulf of California, petroleum having a wide range of compositions forms by hydrothermal alteration of organic matter in Quaternary sediment composed mainly of marine diatomaceous ooze and muddy turbidites. In Escanaba Trough, at the southern end of the Gorda Ridge spreading...
Gas hydrates of the Peruvian outer continental margin
Keith A. Kvenvolden, Miriam Kastner
1990, Proceedings of the Ocean Drilling Program: Scientific Results (112) 517-526
Gas hydrates were recovered during coring by Ocean Drilling Program (ODP) Leg 112 at Sites 685 and 688 on the Peruvian outer continental margin at latitudes of 9° and 11.5°S, where water depths are 5070 and 3820 m, respectively. In addition, nearby Sites 682 and 683 yielded compelling evidence that...

Calc-alkaline, shoshonitic, and primitive tholeiitic lavas from monogenetic volcanoes near Crater Lake, Oregon
Charles R. Bacon
1990, Journal of Petrology (31) 135-166
Quaternary monogenetic volcanism in the High Cascades of Oregon is manifested by cinder cones, lava fields, and small shields. Near Crater Lake caldera, monogenetic lava compositions include: low-K (as low as 0·09% K2O) high-alumina olivine tholeiite (HAOT); medium-K. calc-alkaline basalt, basaltic andesite, and andesite; and shoshonitic basaltic andesite (2·1% K2O,...
