Anderson co-authors paper in
geophysical research journal -
Dr. Steve Anderson, asssociate professor of geology and chairman
of the BHSU science department,
co-authored with three other scientists a paper titled
"Emplacement and Composition of Steep-Sided Domes on
Venus" to be published this year in the Journal of
Working with three NASA-funded planetary geologists from the
Jet Propulsion Laboratory and the University of Pittsburgh, the
paper is a culmination of a three-year study focusing on the use
of radar images acquired by NASA’s Magellan spacecraft to
determine the origin and evolution of the surface of Venus.
Collaborating with Anderson are Dr. David Crown from the
University of Pittsburgh and Drs. Ellen Stofan and Jeff Plaut
from the Jet Propulsion Laboratory. The research is funded by a
$220,000 grant from NASA.
The BH professor said the researchers used Magellan’s radar
to penetrate the thick sulfuric acid-rich atmosphere on Venus to
identify images and interpret geologic structures present on the
planet’s surface. They then compared these features on Venus
to active lava flows on Earth. This comparison enabled the
researchers to determine the processes at work during the
formation of these domes. Once these processes were identified,
the affect of the Venusian environment on the surface morphology
of the domes was considered by constructing mathematical models
of the stresses preset during the cooling of different
compositions of magma.
"The Venusian surface is approximately 550 degrees
centigrade, hot enough to melt lead, and under enormous pressure
from its extensive atmosphere, both of which affect the cooling
of lava and the structures that form on flow surfaces,"
The end result is that researchers demonstrated that lava
domes on Venus are most likely basaltic in composition, similar
to the type of lava observed in Hawaii.
|BHSU undergraduate students Kelly Schoenfield (foreground)
and Denise Neugebauer are collecting research data at Obsidian
Dome in California. Working with Dr. Steve Anderson, the BH team
gathered research data that became part of a study comparing
lava domes on Venus with similar lava domes on Earth. The study,
co-authored by Anderson and three other scientists, will appear
in the Journal of Geophysical Research-Planets this year.
"The findings in this paper disagree with a number of
previous works that suggest that lava domes on Venus are silicic
in composition, similar to that observed at explosive volcanoes
such as Mount St. Helens (Washington) and Mount Pinatubo
(Philippines)," said Anderson. "Silicic magma on Earth
is found in areas where tectonic plates are colliding and
subducting. … suggesting that basaltic magma, which does not
require subduction to form is more compatible with the lack of
evidence of Venusian plate tectonics."
The researchers conducted field studies at lava domes in
California and Oregon for this paper. Several BHSU undergraduate
students served as field assistants for this project, including
Denise Neugebauer, Kelly Schoenfield, Jennifer Mercer, and David
Finnegan. All have since graduated from BHSU and are pursuing
careers. Neugebauer is an environmental specialist for the S.D.
Air National Guard, Schoenfield is completing her master’s
degree at South Dakota School of Mines and Technology, Mercer is
completing her Ph.D. in geochemistry at Dartmouth, and Finnegan
is a graduate student in geography at Indiana State University.
Ruddell Gallery features photos and
haiku by professors -
"Through Both Eyes" is the title of an exhibition of
haiku and photography by Black Hills State professors Dr.
Charles Lamb and Steve Babbitt at the Ruddell Gallery through
Lamb, an associate professor of biology, and Babbitt,
associate professor of communications/photography, combined their
talents to introduce the public to this art form. The exhibition
consists of 33 haiku poems written for and inspired by the
accompanying photographs. There will be a closing reception
Thursday, Sept. 21 from 3 to 5 p.m. at the gallery.
The BH professors have attempted to "capture a moment in
time … and tell us a little bit more about the world around
Haiku is a Japanese verse form, notable for its compression
and suggestiveness. It consists of three unrhymed lines of five,
seven and five syllables.
The Ruddell Gallery is located in the Miller Student Union and
is open to the public at no charge weekdays from 7 a.m. to 4
p.m. and weekends from noon to 5 p.m.

Sarver paper will be published in Fishery
Shane Sarver, associate professor of biology at BHSU, recently
had a paper accepted for publication in the November issue of Fishery
Sarver’s article is titled
"The Occurrence of the Brazilian Sub-species of the Spiny
Lobster (Panulirus argus westonii) in Florida Waters." The
research for this paper and a previous paper "Mitochondrial
DNA Sequence Evidence Supports the Recognition of Two
Sub-species or Species of the Florida Spiny Lobster
argus)" (Journal of Crustacean Biology 18(1):177-186 were
supported by a grant from the Black Hills State University
Sarver has been a member of the
BHSU science faculty since 1996. He teaches classes in biology,
genetics and evolution. He is responsible for developing a
state-of-the-art genetics laboratory on campus featuring an
automated genetic analyzer, which is one of the only instruments
of its type in the entire region. He earned his Ph.D. in zoology
Kopco will present at Adams Museum
Paul Kopco, BHSU instructor, and Helen Alten, conservator and
president of Northern State Conservation Center in St. Paul,
Minn., will present a workshop to demonstrate methods of
conserving and preserving important photographs Sept. 23 at the
Adams Museum and House in Deadwood.
Nearly everyone has irreplaceable family photographs that
they aren’t sure what to do with – or more importantly –
how to care for them for future generations to enjoy and
understand their family history. The museum is presenting the
workshop in conjunction with its yearlong exhibition "A
Snapshot in Time: Photography as Historic Preservation",
which runs through Dec. 31, 2000.
Kopco will demonstrate how to digitally restore photographs by scanning and
utilizing computer programs to manipulate the images to their original
appearance. He is also the designer, composer, and instructor of his company PM
Enterprises, which includes Digital Designs, Dakotah Records, and Knowledge of
Personal Computing On-site/line. Kopco will demonstrate how to digitally
restore photographs by scanning and utilizing computer programs to manipulate
the images to their original appearance.
The workshop will be Sept. 23 from 9 a.m. to 4 p.m., at Deadwood City Hall,
102 Sherman Street. Reservations are required and can be made by calling the
Adams Museum at 605-578-1714.
Johnson, a business instructor at BHSU, is teaching a series of
workshops being offered to MDU employees. The workshops are
sponsored by the university’s Center for Business and
Entrepreneurship and consist of two sessions each of Word,
Excel, Outlook-level 1, and Outlook-level 2. Johnson is teaching
six to seven employees at a time. The workshops, three to four
hours in length, will continue through Sept. 20.
