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. -

Received: 12 May 2020; Accepted: 10 June 2020; Published: 12 June 2020 Abstract: During the glacial episodes of the Quaternary, European forests were restricted to small favourable spots, namely refugia, acting as biodiversity reservoirs. the Iberian, Italian and Balkan peninsulas have been considered as the main glacial refugia of trees in Europe. In this study, we estimate the composition of the last glacial forest in a coastal cave of the Cilento area (SW Italy) in seven time frames, spanning from the last Pleniglacial to the Late Glacial. Charcoal analyses were performed in seven archaeological layers. Furthermore, a paleoclimate modelling (Maxent) approach was used to complement the taxonomic identification of charcoal fragments to estimate the past potential distribution of tree species in Europe. Our results showed that the mesothermophilous forest survived in this region in the core of the Mediterranean basin during the Last Glacial Period (LGP, since ~36 ka cal BP), indicating that this area played an important role as a reservoir of woodland biodiversity. -
Coastal Reservoir-A Technology That May Dominate Future Water Supply Shu-Qing Yang School of Civil, Mining and Environmental Engineering, Univ
Journal of Water Resource and Hydraulic Engineering Oct. 2015, Vol. 4 Iss. 4, PP. 388-397 Coastal Reservoir-a Technology That May Dominate Future Water Supply Shu-Qing Yang School of Civil, Mining and Environmental Engineering, Univ. of Wollongong [email protected] Abstract-New large dam construction is a worldwide problem due to its negative impacts on the ecosystem, and as a result, it is crucial to investigate the future water supply infrastructures. After comparison with the existing solutions for water supply, such as inland reservoirs, desalination plants and wastewater reuse facilities, we conclude that coastal reservoir will be the dominant solution in the future because: a) increasing numbers of people migrate towards coastal/deltaic regions and more megacities are emerging along the coastline; consequently the water shortage on the coastline is the most severe; b) the future water deficit is huge (about 10 times the flow of the Nile river), with no solution other than the implementations of coastal reservoirs, freshwater reservoirs in the seawater to develop runoff from rivers, able to provide so much water. Now the world only uses 1/6 of total runoff, with the remaining 5/6 of runoff lost to the sea; c) all solutions for water supply have significant impacts on the environment, and only the strategy of using coastal reservoirs is sustainable, as it is without brine as a by-productor high carbon emissions. This paper discusses the supply of water to Beijing and Tianjin, the most notorious region in the world for its thirst. It is found that the water shortage problem in the region can be solved, the efficiency of South-North Water Diversion Project can be improved significantly, and carbon emission can be reduced in the region if this new solution is applied. -

Barboza2 1 COMAR- South West Atlantic Coastal and Marine Geology Group; 2 Centro de Estudos de Geologia Costeira e Oceânica – CECO/IG/UFRGS. RESUMO A plataforma continental Atlântica do Rio Grande do Sul e Uruguai foi utilizada como laboratório natural para testar as relações entre propriedades de tamanho de grão e ambiente sedimentar. A evolução Pleistoceno/Holoceno da região foi intensamente estudada através de um mapeamento detalhado, e de estudos sedimentológicos e estratigráficos, oferecendo, dessa forma, uma excelente oportunidade para esse tipo de trabalho. Acumulações de areia e cascalho, vinculadas a níveis de estabilização identificados da transgressão Holocênica, localizados nas isóbatas de 110-120 e 20-30 metros, fornecem elementos confiáveis relacionados com a fonte, transporte e nível de energia de deposição e podem ser utilizados como linhas de evidencias na interpretação ambiental. ABSTRACT The Atlantic Rio Grande do Sul (Brazil) and Uruguay inner continental shelf was used as a natural laboratory to test the relationship between grain-size properties and sedimentary environment. The Pleistocene/Holocene evolution of the region was intensively studied through detailed mapping, sedimentological and stratigraphic research thus offering an excellent opportunity of developing this type of work. Sand and gravel deposits linked with identified stillstands of the Holocene transgression located at 110-120 and 20-30 meters isobath provided elements related to the source, transport and depositional energy level and can be used as a tool for environmental interpretation. Keywords: marine deposits, grain-size, sand-gravel, Holocene. -

Appendix I Lunar and Martian Nomenclature
APPENDIX I LUNAR AND MARTIAN NOMENCLATURE LUNAR AND MARTIAN NOMENCLATURE A large number of names of craters and other features on the Moon and Mars, were accepted by the IAU General Assemblies X (Moscow, 1958), XI (Berkeley, 1961), XII (Hamburg, 1964), XIV (Brighton, 1970), and XV (Sydney, 1973). The names were suggested by the appropriate IAU Commissions (16 and 17). In particular the Lunar names accepted at the XIVth and XVth General Assemblies were recommended by the 'Working Group on Lunar Nomenclature' under the Chairmanship of Dr D. H. Menzel. The Martian names were suggested by the 'Working Group on Martian Nomenclature' under the Chairmanship of Dr G. de Vaucouleurs. At the XVth General Assembly a new 'Working Group on Planetary System Nomenclature' was formed (Chairman: Dr P. M. Millman) comprising various Task Groups, one for each particular subject. For further references see: [AU Trans. X, 259-263, 1960; XIB, 236-238, 1962; Xlffi, 203-204, 1966; xnffi, 99-105, 1968; XIVB, 63, 129, 139, 1971; Space Sci. Rev. 12, 136-186, 1971.

1 Coastal Protection
Notes for GE4211 Field Trip to Marina Barrage (2 Apr ‘18) Denitza Voutchkova 1 COASTAL PROTECTION Coastal protection is one of the priorities in dealing with climate change effects in Singapore (the other is “improving drainage”). Minimum land reclamation level in Singapore was raised from 3 to 4 m above mean sea level in 2011 to address the projected sea level raise under the 2nd Climate change study. Defense from erosion: 70-80% of Singapore’s coastline: either walls or stone embankment 30-20% is “natural”, e.g. sandy beaches and mangroves Developing appropriate coastal measures coastal engineering, wave dynamics, coastal morphology, and hydrodynamics. Figure 1 2011 distribution of seawalls (in orange) around Singapore (source: Lai et al 2015, uploaded to IVLE, https://doi.org/10.1016/j.ocecoaman.2014.11.006) Building and Construction Authority (BCA) has commissioned a study that will form the national framework for coastal protection measures (the Straits Times, Jan 5, 2018). The study started in 2013 and was initially planned to be completed by the end of 2017, but has been pushed back to the 2nd half of 2018. The reason for this delay was because “more time is needed to consider fresh input and to engage stakeholders, so coastal protection strategies will complement development plans” (the Straits Times, see link below).

45. Sedimentary Facies and Depositional History of the Iberia Abyssal Plain1
Whitmarsh, R.B., Sawyer, D.S., Klaus, A., and Masson, D.G. (Eds.), 1996 Proceedings of the Ocean Drilling Program, Scientific Results, Vol. 149 45. SEDIMENTARY FACIES AND DEPOSITIONAL HISTORY OF THE IBERIA ABYSSAL PLAIN1 D. Milkert,2 B. Alonso,3 L. Liu,4 X. Zhao,5 M. Comas,6 and E. de Kaenel4 ABSTRACT During Leg 149, a transect of five sites (Sites 897 to 901) was cored across the rifted continental margin off the west coast of Portugal. Lithologic and seismostratigraphical studies, as well as paleomagnetic, calcareous nannofossil, foraminiferal, and dinocyst stratigraphic research, were completed. The depositional history of the Iberia Abyssal Plain is generally characterized by downslope transport of terrigenous sedi- ments, pelagic sedimentation, and contourite sediments. Sea-level changes and catastrophic events such as slope failure, trig- gered by earthquakes or oversteepening, are the main factors that have controlled the different sedimentary facies. We propose five stages for the evolution of the Iberia Abyssal Plain: (1) Upper Cretaceous and lower Tertiary gravitational flows, (2) Eocene pelagic sedimentation, (3) Oligocene and Miocene contourites, (4) a Miocene compressional phase, and (5) Pliocene and Pleistocene turbidite sedimentation. Major input of terrigenous turbidites on the Iberia Abyssal Plain began in the late Pliocene at 2.6 Ma.

Reservoir Ages in Eastern Pacific Coastal and Estuarine Waters B
[RADIOCARBON, VOL. 38, No. 3,19%, P. 573-582] RESERVOIR AGES IN EASTERN PACIFIC COASTAL AND ESTUARINE WATERS B. LYNN INGRAM Department of Geography, University of California, Berkeley, California 94720 USA and JOHN R. SOUTHON Center for Accelerator Mass Spectrometry, L-397, Lawrence Livermore National Laboratory Livermore, California 94551 USA ABSTRACT. We have refined marine reservoir age estimates for eastern Pacific coastal waters with radiocarbon measure- ments of mollusk shells collected prior to 1950. We have also investigated interspecific variability in 14C ages for historic and ancient shells from San Francisco Bay. INTRODUCTION Globally, ocean surface waters are depleted in radiocarbon content relative to the atmosphere b an amount equivalent to 40014C Y Y r. Regionally the oceans devia to from this value, reflecting variations in upwelling (Stuiver, Pearson and Braziunas 1986), freshwater inflow in coastal regions S iker 1980), and interhemis heric variations in atmospheric C content (Stuiver and Braziunas 1993). Knowledge of the value of the regional deviation from the ocean reservoir age (or AR) is necessary to accurately calibrate 14C ages of marine materials. Since the 1950s, determination of AR values by surface water 14( measurements has been precluded due to the artificially high 14C activity in surface waters from nuclear testing. Thus, AR values in coastal waters must be determined indirectly from 14C measurements of carbonate shells or other marine materials of known age collected prior to 1950. Previous 14C measurements of known-age mollusk shells indicate an average AR for coastal Cali- fornia of 225 ± 15 yr, for seven analyses (Berger, Taylor and Libby 1966; Robinson and Trimble 1981), corresponding 14C to a significant depletion. -
Orientation, Sphericity and Roundness Evaluation of Particles Using Alternative 3D Representations
Orientation, Sphericity and Roundness Evaluation of Particles Using Alternative 3D Representations Irving Cruz-Mat´ıasand Dolors Ayala Department de Llenguatges i Sistemes Inform´atics, Universitat Polit´ecnicade Catalunya, Barcelona, Spain December 2013 Abstract Sphericity and roundness indices have been used mainly in geology to analyze the shape of particles. In this paper, geometric methods are proposed as an alternative to evaluate the orientation, sphericity and roundness indices of 3D objects. In contrast to previous works based on digital images, which use the voxel model, we represent the particles with the Extreme Vertices Model, a very concise representation for binary volumes. We define the orientation with three mutually orthogonal unit vectors. Then, some sphericity indices based on length measurement of the three representative axes of the particle can be computed. In addition, we propose a ray-casting-like approach to evaluate a 3D roundness index. This method provides roundness measurements that are highly correlated with those provided by the Krumbein's chart and other previous approach. Finally, as an example we apply the presented methods to analyze the sphericity and roundness of a real silica nano dataset.
