  • Thermal Studies of Martian Channels and Valleys Using Termoskan Data
    JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 99, NO. El, PAGES 1983-1996, JANUARY 25, 1994 Thermal studiesof Martian channelsand valleys using Termoskan data BruceH. Betts andBruce C. Murray Divisionof Geologicaland PlanetarySciences, California Institute of Technology,Pasadena The Tennoskaninstrument on boardthe Phobos '88 spacecraftacquired the highestspatial resolution thermal infraredemission data ever obtained for Mars. Included in thethermal images are 2 km/pixel,midday observations of severalmajor channel and valley systems including significant portions of Shalbatana,Ravi, A1-Qahira,and Ma'adimValles, the channelconnecting Vailes Marineris with HydraotesChaos, and channelmaterial in Eos Chasma.Tennoskan also observed small portions of thesouthern beginnings of Simud,Tiu, andAres Vailes and somechannel material in GangisChasma. Simultaneousbroadband visible reflectance data were obtainedfor all but Ma'adimVallis. We find thatmost of the channelsand valleys have higher thermal inertias than their surroundings,consistent with previousthermal studies. We show for the first time that the thermal inertia boundariesclosely match flat channelfloor boundaries.Also, butteswithin channelshave inertiassimilar to the plainssurrounding the channels,suggesting the buttesare remnants of a contiguousplains surface. Lower bounds ontypical channel thermal inertias range from 8.4 to 12.5(10 -3 cal cm-2 s-1/2 K-I) (352to 523 in SI unitsof J m-2 s-l/2K-l). Lowerbounds on inertia differences with the surrounding heavily cratered plains range from 1.1 to 3.5 (46 to 147 sr). Atmosphericand geometriceffects are not sufficientto causethe observedchannel inertia enhancements.We favornonaeolian explanations of the overall channel inertia enhancements based primarily upon the channelfloors' thermal homogeneity and the strongcorrelation of thermalboundaries with floor boundaries. However,localized, dark regions within some channels are likely aeolian in natureas reported previously.

De flesta av dem hava redan läm- nat livets vädjobana, ännu flere äro redan totalt glömda. Och dock hava många av dem utfört ett dagsverke, som vore värt att ihågkommas. Genom sitt intresse för yrket, skicklighet, plikttro- het hava de bidragit till att göra sitt fosterland känt och aktat där borta i kejsardömet i långt större utsträckning än man vore böjd att förmoda, om man blott dömer efter antalet. Härpå ty- der också i sin mån den vackra karriär många av dem kunnat göra där. Arbetet grundar sig förnämligast på ryska marinens officiella månadstidskrift Morskoj Sbornik, däri samtliga dagorder från och med 1848 ända till världskrigets utbrott publicerats. Jämsides därmed har flottans officiella rangrulla (Obstschij Morskoj Spisok) anlitats. Denna går tillbaka till 1700-talets början, men slutar sedan en ringa del av officerskåren under Alexander II:s regerings- tid förtecknats (bokstäverna A, B, V och G). Betecknande nog äro dessa två källor, ehuru båda officiella, långt ifrån samstäm- miga; skiljaktigheterna äro både talrika och stora. Då sålunda primärmaterialet varit varken absolut tillförlitligt eller fullständigt, hava icke heller efterföljande biografiska uppgifter kunnat göras så noggranna och felfria som det varit önskligt. Så vitt möjligt hava dock kompletterande uppgifter sökts på annat håll.

  • Intraplate Earthquakes in North China
    5 Intraplate earthquakes in North China mian liu, hui wang, jiyang ye, and cheng jia Abstract North China, or geologically the North China Block (NCB), is one of the most active intracontinental seismic regions in the world. More than 100 large (M > 6) earthquakes have occurred here since 23 BC, including the 1556 Huax- ian earthquake (M 8.3), the deadliest one in human history with a death toll of 830,000, and the 1976 Tangshan earthquake (M 7.8) which killed 250,000 people. The cause of active crustal deformation and earthquakes in North China remains uncertain. The NCB is part of the Archean Sino-Korean craton; ther- mal rejuvenation of the craton during the Mesozoic and early Cenozoic caused widespread extension and volcanism in the eastern part of the NCB. Today, this region is characterized by a thin lithosphere, low seismic velocity in the upper mantle, and a low and flat topography. The western part of the NCB consists of the Ordos Plateau, a relic of the craton with a thick lithosphere and little inter- nal deformation and seismicity, and the surrounding rift zones of concentrated earthquakes. The spatial pattern of the present-day crustal strain rates based on GPS data is comparable to that of the total seismic moment release over the past 2,000 years, but the comparison breaks down when using shorter time windows for seismic moment release. The Chinese catalog shows long-distance roaming of large earthquakes between widespread fault systems, such that no M ࣙ 7.0 events ruptured twice on the same fault segment during the past 2,000 years.

  • The Paleoecology and Fire History from Crater Lake
    THE PALEOECOLOGY AND FIRE HISTORY FROM CRATER LAKE, COLORADO: THE LAST 1000 YEARS By Charles T. Mogen A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science in Environmental Science and Policy Northern Arizona University August 2018 Approved: R. Scott Anderson, Ph.D., Chair Nicholas P. McKay, Ph.D. Darrell S. Kaufman, Ph.D. Abstract High-resolution pollen, plant macrofossil, charcoal and pyrogenic Polycyclic Aromatic Hydrocarbon (PAH) records were developed from a 154 cm long sediment core collected from Crater Lake (37.39°N, 106.70°W; 3328 m asl), San Juan Mountains, Colorado. Several studies have explored Holocene paleo-vegetation and fire histories from mixed conifer and subalpine bogs and lakes in the San Juan and southern Rocky Mountains utilizing both palynological and charcoal studies, but most have been at relatively low resolution. In addition to presenting the highest resolution palynological study over the last 1000 years from the southern Rocky Mountains, this thesis also presents the first high-resolution pyrogenic PAH and charcoal paired analysis aimed at understanding both long-term fire history and the unresolved relationship between how each of these proxies depict paleofire events. Pollen assemblages, pollen ratios, and paleofire activity, indicated by charcoal and pyrogenic PAH records, were used to infer past climatic conditions. Although the ecosystem surrounding Crater Lake has remained a largely spruce (Picea) dominated forest, the proxies developed in this thesis suggest there were two distinct climate intervals between ~1035 to ~1350 CE and ~1350 to ~1850 CE in the southern Rocky Mountains, associated with the Medieval Climate Anomaly (MCA) and Little Ice Age (LIA) respectively.

  • SMIP13 Seminar Proceedings OBSERVATIONS from the APRIL 20, 2013 LUSHAN COUNTY, YA'an CITY, SICHUAN PROVINCE, CHINA EARTHQUAKE
    SMIP13 Seminar Proceedings OBSERVATIONS FROM THE APRIL 20, 2013 LUSHAN COUNTY, YA’AN CITY, SICHUAN PROVINCE, CHINA EARTHQUAKE Marshall Lew AMEC Environment & Infrastructure, Inc. Los Angeles, California Abstract The April 20, 2013 Lushan earthquake followed the 2008 Great Wenchuan earthquake by almost five years. Although the rupture also started in the Longmenshan fault zone, the Lushan earthquake is not an aftershock. Although similar damage and disruptions to infrastructure and society occurred, it was of a smaller scale and not unexpected due to the short time for the lessons from Wenchuan to be applied. There were some examples of lessons learned and the strong motion dataset obtained in this event will prove valuable in assessing how effective the actions taken have been. The visual observations were made on May 27 and 28, 2013 in Lushan. Introduction On April 20, 2013, at 8:02 am (Beijing Time), an earthquake occurred in Lushan County of Ya’an City in Sichuan Province in southwestern China. The epicenter was located at 30o 17’ 02” N and 102o 57’ 22” E, about 120 km from the major city of Chengdu; see Figure 1. Ya’an City is a prefecture level city in the western part of Sichuan Province and has a population of about 1.5 million people and is the location of one of China’s main centers for the protection of the endangered giant panda. Sichuan Province is known as the “Province of Abundance.” The province is a leading agricultural region of China and the province is also very rich in mineral resources, including large natural gas reserves.

  • 16. Ice in the Martian Regolith
    16. ICE IN THE MARTIAN REGOLITH S. W. SQUYRES Cornell University S. M. CLIFFORD Lunar and Planetary Institute R. O. KUZMIN V.I. Vernadsky Institute J. R. ZIMBELMAN Smithsonian Institution and F. M. COSTARD Laboratoire de Geographie Physique Geologic evidence indicates that the Martian surface has been substantially modified by the action of liquid water, and that much of that water still resides beneath the surface as ground ice. The pore volume of the Martian regolith is substantial, and a large amount of this volume can be expected to be at tem- peratures cold enough for ice to be present. Calculations of the thermodynamic stability of ground ice on Mars suggest that it can exist very close to the surface at high latitudes, but can persist only at substantial depths near the equator. Impact craters with distinctive lobale ejecta deposits are common on Mars. These rampart craters apparently owe their morphology to fluidhation of sub- surface materials, perhaps by the melting of ground ice, during impact events. If this interpretation is correct, then the size frequency distribution of rampart 523 524 S. W. SQUYRES ET AL. craters is broadly consistent with the depth distribution of ice inferred from stability calculations. A variety of observed Martian landforms can be attrib- uted to creep of the Martian regolith abetted by deformation of ground ice. Global mapping of creep features also supports the idea that ice is present in near-surface materials at latitudes higher than ± 30°, and suggests that ice is largely absent from such materials at lower latitudes. Other morphologic fea- tures on Mars that may result from the present or former existence of ground ice include chaotic terrain, thermokarst and patterned ground.

  • A Possible Late Pleistocene Impact Crater in Central North America and Its Relation to the Younger Dryas Stadial
    A POSSIBLE LATE PLEISTOCENE IMPACT CRATER IN CENTRAL NORTH AMERICA AND ITS RELATION TO THE YOUNGER DRYAS STADIAL SUBMITTED TO THE FACULTY OF THE UNIVERSITY OF MINNESOTA BY David Tovar Rodriguez IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE Howard Mooers, Advisor August 2020 2020 David Tovar All Rights Reserved ACKNOWLEDGEMENTS I would like to thank my advisor Dr. Howard Mooers for his permanent support, my family, and my friends. i Abstract The causes that started the Younger Dryas (YD) event remain hotly debated. Studies indicate that the drainage of Lake Agassiz into the North Atlantic Ocean and south through the Mississippi River caused a considerable change in oceanic thermal currents, thus producing a decrease in global temperature. Other studies indicate that perhaps the impact of an extraterrestrial body (asteroid fragment) could have impacted the Earth 12.9 ky BP ago, triggering a series of events that caused global temperature drop. The presence of high concentrations of iridium, charcoal, fullerenes, and molten glass, considered by-products of extraterrestrial impacts, have been reported in sediments of the same age; however, there is no impact structure identified so far. In this work, the Roseau structure's geomorphological features are analyzed in detail to determine if impacted layers with plastic deformation located between hard rocks and a thin layer of water might explain the particular shape of the studied structure. Geophysical data of the study area do not show gravimetric anomalies related to a possible impact structure. One hypothesis developed on this works is related to the structure's shape might be explained by atmospheric explosions dynamics due to the disintegration of material when it comes into contact with the atmosphere.

Introduction: Previously, numerous studies re- age is available of the studied landforms. For Earth ported on glacier landforms on Mars such as viscous comparison we used publicly available Google Earth flow features (VVF) [1], glacier-like flows (GLF) [2] images. and lobate debris aprons (LDA) [3] where water-ice is Observations and results: The area is dominated by believed to be present under insulating debris cover fretted terrain, mesas, cliffs and flat floored valleys.

In terms of possible glacial erosional and and are a few hundred to a more than a thousand me- depositional landforms most studies have focused on ters in height. The cliff is characterized by deeply in- small-scale moraine-like ridges that are associated to cised valley systems. Here we report observations from gully systems in interior crater environments [e.g., 5], two valleys. large-scale glacier landforms at the equatorial volcanic province [e.g., 6], landforms suggesting basal glacial meltwater processes [7,8] and possible drop-moraines from past CO2 glaciers [9]. In this study we surveyed an area that border areas of known VVF's and GLF's along the dichotomy.
