Glossary Glossary
Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts. -
Martian Crater Morphology
ANALYSIS OF THE DEPTH-DIAMETER RELATIONSHIP OF MARTIAN CRATERS A Capstone Experience Thesis Presented by Jared Howenstine Completion Date: May 2006 Approved By: Professor M. Darby Dyar, Astronomy Professor Christopher Condit, Geology Professor Judith Young, Astronomy Abstract Title: Analysis of the Depth-Diameter Relationship of Martian Craters Author: Jared Howenstine, Astronomy Approved By: Judith Young, Astronomy Approved By: M. Darby Dyar, Astronomy Approved By: Christopher Condit, Geology CE Type: Departmental Honors Project Using a gridded version of maritan topography with the computer program Gridview, this project studied the depth-diameter relationship of martian impact craters. The work encompasses 361 profiles of impacts with diameters larger than 15 kilometers and is a continuation of work that was started at the Lunar and Planetary Institute in Houston, Texas under the guidance of Dr. Walter S. Keifer. Using the most ‘pristine,’ or deepest craters in the data a depth-diameter relationship was determined: d = 0.610D 0.327 , where d is the depth of the crater and D is the diameter of the crater, both in kilometers. This relationship can then be used to estimate the theoretical depth of any impact radius, and therefore can be used to estimate the pristine shape of the crater. With a depth-diameter ratio for a particular crater, the measured depth can then be compared to this theoretical value and an estimate of the amount of material within the crater, or fill, can then be calculated. The data includes 140 named impact craters, 3 basins, and 218 other impacts. The named data encompasses all named impact structures of greater than 100 kilometers in diameter. -
Constraints on the Timescale of Animal Evolutionary History
Palaeontologia Electronica palaeo-electronica.org Constraints on the timescale of animal evolutionary history Michael J. Benton, Philip C.J. Donoghue, Robert J. Asher, Matt Friedman, Thomas J. Near, and Jakob Vinther ABSTRACT Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are fundamental to nearly every evolutionary model and process. Rates need dates. There is much debate on the most appropriate and reasonable ways in which to date the tree of life, and recent work has highlighted some confusions and complexities that can be avoided. Whether phylogenetic trees are dated after they have been estab- lished, or as part of the process of tree finding, practitioners need to know which cali- brations to use. We emphasize the importance of identifying crown (not stem) fossils, levels of confidence in their attribution to the crown, current chronostratigraphic preci- sion, the primacy of the host geological formation and asymmetric confidence intervals. Here we present calibrations for 88 key nodes across the phylogeny of animals, rang- ing from the root of Metazoa to the last common ancestor of Homo sapiens. Close attention to detail is constantly required: for example, the classic bird-mammal date (base of crown Amniota) has often been given as 310-315 Ma; the 2014 international time scale indicates a minimum age of 318 Ma.

Analysis of Polarimetric Mini-SAR and Mini-RF Datasets for Surface Characterization and Crater Delineation on Moon †
Proceeding Paper Analysis of Polarimetric Mini-SAR and Mini-RF Datasets for Surface Characterization and Crater Delineation on Moon † Himanshu Kumari and Ashutosh Bhardwaj * Photogrammetry and Remote Sensing Department, Indian Institute of Remote Sensing, Dehradun 248001, India; [email protected] * Correspondence: [email protected]; Tel.: +91-9410319433 † Presented at the 3rd International Electronic Conference on Atmospheric Sciences, 16–30 November 2020; Available online: https://ecas2020.sciforum.net/. Abstract: The hybrid polarimetric architecture of Mini-SAR and Mini-RF onboard Indian Chan- drayaan-1 and LRO missions were the first to acquire shadowed polar images of the Lunar surface. This study aimed to characterize the surface properties of Lunar polar and non-polar regions con- taining Haworth, Nobile, Gioja, an unnamed crater, Arago, and Moltke craters and delineate the crater boundaries using a newly emerged approach. The Terrain Mapping Camera (TMC) data of Chandrayaan-1 was found useful for the detection and extraction of precise boundaries of the cra- ters using the ArcGIS Crater tool. The Stokes child parameters estimated from radar backscatter like the degree of polarization (m), the relative phase (δ), Poincare ellipticity (χ) along with the Circular Polarization Ratio (CPR), and decomposition techniques, were used to study the surface attributes of craters. The Eigenvectors and Eigenvalues used to measure entropy and mean alpha showed distinct types of scattering, thus its comparison with m-δ, m-χ gave a profound conclusion to the lunar surface. The dominance of surface scattering confirmed the roughness of rugged material. The results showed the CPR associated with the presence of water ice as well as a dihedral reflection inside the polar craters. -

Marriage of Basalt and His Wife River by Rick Rubin ©2001
The Marriage of Basalt and his Wife River By Rick Rubin ©2001 Sixteen million years ago, a vast outpouring of lava from eastern Oregon began. The greatest lava flow in North America, that lava covered 80,000 square miles with molten rock. At that time, the Columbia River had her bed where Salem is now. A (miocene) basalt path, covered by (Quaternary) alluvial sediment just south of Salem shows the place. Her bed reached the sea north of the present Lincoln City. That lava outpouring got into her bed. Filled it up. Got hard. Became grass covered Cascade Head, north of Lincoln City. Husband-like, Basalt shouldered his river/wife north and west. She had to make a new bed for herself. Time and again those cracks to the east poured out lava, which flowed down the river’s new bed, which was always to the north of the earlier one, and came to the sea, or perhaps simply stopped, for the sea was as much as 300 miles farther west than it is now some of the time. (That was Ice Age’s doing. The Earth’s water was all tied up in glacier ice). The next time fiery Basalt poured out from east of where the Cascade mountains are now, and coming into Columbia River’s bed flowed down to the sea, it cooled into slim, steep sided, jutting Cape Lookout A million or so years later, Basalt flowed into the river’s attractive bed again, and this time, when he reached the sea, became blocky Cape Meares, just south of Tillamook Bay Later Basalt may have made a cape at the north entrance to Great Basin petroglyphs from Petroglyphs of Oregon, Luther Cressmann, Tillamook Bay of which some basalt rocks near the shore are the only relics. -

The Mountain of a Thousand Holes Shipwreck Traditions and Treasure Hunting on Oregon’s North Coast CAMERON LA FOLLETTE, DENNIS GRIFFIN, AND DOUGLAS DEUR EURO-AMERICANS in coastal communities conflated and amplified Native American oral traditions of shipwrecks in Tillamook County, increasingly focusing the stories on buried treasure. This focus led to a trickle, and then a procession, of treasure-seekers visiting the northern Oregon coast, reach- ing full crescendo by the mid to late twentieth century. The seekers’ theo- ries ranged from the fairly straightforward to the wildly carnivalesque, with many bizarre permutations. Neahkahnie Mountain and its beaches became the premier treasure-hunting sites in Oregon, based on the mountain’s prominence in popular lore, linked to unverified stories about the wreck of a Spanish ship. -
Drainage Basin Morphology in the Central Coast Range of Oregon
AN ABSTRACT OF THE THESIS OF WENDY ADAMS NIEM for the degree of MASTER OF SCIENCE in GEOGRAPHY presented on July 21, 1976 Title: DRAINAGE BASIN MORPHOLOGY IN THE CENTRAL COAST RANGE OF OREGON Abstract approved: Redacted for privacy Dr. James F. Lahey / The four major streams of the central Coast Range of Oregon are: the westward-flowing Siletz and Yaquina Rivers and the eastward-flowing Luckiamute and Marys Rivers. These fifth- and sixth-order streams conform to the laws of drain- age composition of R. E. Horton. The drainage densities and texture ratios calculated for these streams indicate coarse to medium texture compa- rable to basins in the Carboniferous sandstones of the Appalachian Plateau in Pennsylvania. Little variation in the values of these parameters occurs between basins on igneous rook and basins on sedimentary rock. The length of overland flow ranges from approximately i mile to i mile. Two thousand eight hundred twenty-five to 6,140 square feet are necessary to support one foot of channel in the central Coast Range. Maximum elevation in the area is 4,097 feet at Marys Peak which is the highest point in the Oregon Coast Range. The average elevation of summits in the thesis area is ap- proximately 1500 feet. The calculated relief ratios for the Siletz, Yaquina, Marys, and Luckiamute Rivers are compara- ble to relief ratios of streams on the Gulf and Atlantic coastal plains and on the Appalachian Piedmont. Coast Range streams respond quickly to increased rain- fall, and runoff is rapid. The Siletz has the largest an- nual discharge and the highest sustained discharge during the dry summer months. -
