Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: May 1981 Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: May 1981
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory; therefore it should be regarded as preliminary.

Effects of volcanism on the glaciers of Mount St. Helens Effects of volcanism on the glaciers of Mount St. Helens
The cataclysmic eruption of Mount St. Helens May 18, 1980, removed 2.9 km2 (about 0.13 km3) of glacier snow and ice including a large part of Shoestring, Forsyth, Wishbone, Ape, Nelson, and all of Loowit and Leschi Glaciers. Minor eruptions and bulging of the volcano from March 27 to May 17 shattered glaciers which were on the deforming rock and deposited ash on other glaciers. Thick ash...

Did ice streams carve martian outflow channels? Did ice streams carve martian outflow channels?
Outflow channels on Mars1 are long sinuous linear depressions that occur mostly in the equatorial area (±30° lat.). They differ from small valley networks2 by being larger and arising full born from chaotic terrains. Outflow channels resemble terrestrial stream beds, and their origin has generally been attributed to water3–5 in catastrophic floods6,7 or mudflows8. The catastrophic-flood...

Preliminary design study for a National Digital Seismograph Network Preliminary design study for a National Digital Seismograph Network
Recently, the National Research Council published a report by the Panel on National, Regional, and Local Seismograph Networks of the Committee on Seismology in which the principal recommendation was for the establishment of a national digital seismograph network (NDSN). The Panel Report (Bolt, 1980) addresses both the need and the scientific requirements for the new national network. The...

Small landslide types and controls in glacial deposits: Lower Skagit river drainage, northern cascade range, Washington Small landslide types and controls in glacial deposits: Lower Skagit river drainage, northern cascade range, Washington
Observations of 167 small, shallow landslides spanning a 22-year period on extensively logged slopes of Quaternary terraces in the lower Skagit and Baker Valleys, Washington, shows that there is a relationship between the common slope failures in this area and the slope angle, stratigraphy, and logging practices. Landslide frequency increases upvalley, as do mean annual precipitation and...

Morphology and processes associated with the accumulation of the fine-grained sediment deposit on the southern New England shelf Morphology and processes associated with the accumulation of the fine-grained sediment deposit on the southern New England shelf
A 13,000 km2 area of the southern New England Continental Shelf which is covered by anomalously fine-grained sediment has been surveyed by means of high-resolution, seismic-reflection and side-scan sonar techniques to map its morphology and structure, and a near-bottom instrument system contributed to understanding present activity of the deposit. Seismic-reflection profiles show that...
