We have examined if these changes are within the range off natural variations, as given my multi-millennial “control” simulations with conventional climate models. It turns out that temperature has seen an increase in all seasons, as well as annually, which is beyond this range, so that we may conclude that we “detect” a change, which needs explanation by anthropogenic factors. Similarly for precipitation amounts, even if the pattern in different seasons and for the year is variable. When we compare these changes “which need explanation” with what climate models suggest as responses to elevated greenhouse gas concentrations (GHG), we find that the induced temperature change fits the sign of the observed change, but is too weak. In terms of precipitation, we find sometimes inconsistency, i.e., opposite sign, and different magnitudes. Thus, the change may be in part related to elevated GHGs, but not entirely so. To shed further light on the attribution issue, we fitted a regression model, which describes BSR annual temperature and precipitation amounts as a response to Northern Hemisphere temperature and BSR aerosol emissions. The predictor “Northern Hemisphere temperature” is supposed to describe mostly the GHG related change, but it includes also global aerosol effects, global volcanic effects as well as cosmic effects such as solar activity. The regression models fit the observed records rather well, even if the year-to-year variability is underestimated, as was to be expected. Then, we modified the BSR aerosol emissions in the regression model – being constant at low levels since 1920, and being constant at high levels since 1980. It turns out that constant emissions lead to a reduced temperature increase in recent decades and to a positive trend in precipitation amounts. Thus, regional aerosol emissions together with global GHG atmospheric accumulation together may be “attributed” as causes of the recent trends in BSR climate change, at least qualitatively. 8 10th Baltic Sea Science Congress 17 June L2 IN SEARCH OF THE BEST CROSS‐BORDER AND ‐SECTOR GOVERNANCE MODEL Mike Elliott Institute of Estuarine & Coastal Studies, University of Hull, United Kingdom [email protected] Marine management worldwide has to tackle transboundary and cross-sectoral issues respectively because of seas encompassing the waters of many countries and because of the many activities in the seas and their catchments. The nature of the marine environment, in having unbounded boundaries (because of the dynamic nature of both the natural and societal aspects) and moving baselines (because of climate change) makes it a particularly challenging environment to manage. Accordingly, regional seas, such as the Baltic, have evolved environmental protection bodies such as HELCOM which have to operate across geo-political boundaries but which have to encompass all the prevailing philosophies and approaches to marine environmental management; the latter are within national, regional, international and global governance mechanisms. This presentation illustrates an integrated marine management framework based on the DAPSI(W)R(M) approach (Drivers, Activities, Pressures, State changes, Impacts (on human Welfare) and Responses (using Measures)), the Ecosystem Approach, the 10-tenets of sustainable management, and the Risk Assessment and Risk Management Framework. This takes note of vertical integration in governance and horizontal integration across stakeholders by showing the system of interlinked European marine governance, the plethora of bodies involved in marine management in a country, and the stakeholder typology. Finally, the presentation shows the successes of such approaches but also notes the impediments to a successful and sustainable management outcome. 9 10th Baltic Sea Science Congress 18 June L3 PATTERNS OF BIODIVERSITY IN COASTAL BENTHIC ECOSYSTEMS: A COMPARISON FROM THE GENETIC TO THE SYSTEM LEVEL AT EUROPEAN SCALE Herman Hummel Royal Netherlands Institute for Sea Research, the Netherlands [email protected] Along Europe a northeastward shift in distribution of marine species has been noticed and often attributed to global change. The best examples are available for pelagic marine species and for benthic species at national level. However, the pattern, degree, and eventual consequences of changes, of the biodiversity in benthic coastal ecosystems at larger European scale remains largely unknown. To address this issue, the gradients and relations in genetic, ecophysiological and community diversity (and impact of changes) in coastal benthic systems and a few key-species were assessed in parallel in a range of European coastal ecosystems using harmonised tools and methods. In this presentation we will show examples of patterns of diversity at different organisational levels in benthic ecosystems along the European coastline as obtained in the BIOCOMBE and EMBOS projects. In series of surveys, translocation experiments in the field, and exposure experiments in the lab, carried out at a range of marine stations along the European coastline, aspects of the degree and variation in genetic, ecophysiological and community diversity of benthos have been studied during several years. A focus has been on zoomacrobenthic communities of shallow coastal systems and in particular on the diversity of two key-species, the clam Macoma balthica and the mussel Mytilus spp. in the Mediterranean, Atlantic and Baltic For the mussels as well as clams distinct genetic groups could be recognized. The genetic diversity of the studied key-species showed opposite gradients, i.e. for clams an increase of diversity towards the North, yet for mussels a decrease. The latitudinal gradients and distinct genetic groups are (partly) explained by the geological history (e.g. alternation of ice-ages), present major geographic barriers (Bosporus, Gibraltar and Sont-Kattegat), and recent age of some areas (as Baltic and Black Sea) in comparison with other European regions. The distinct genetic groups in both the key species largely coincided with the distribution of separate ecophysiological groups (ecotypes). Particularly the respiration rates, and to 10 10th Baltic Sea Science Congress a lesser extent the growth rates, can be linked to genetic markers. Clear patterns with latitude (North to South), temperature and salinity gradients and among regions (Baltic, Atlantic, Mediterranean) were found. The clams from the southern French Atlantic coast, i.e. living at the edge of their natural range, showed the lowest genetic diversity, coinciding with their higher sensitivity to disturbance. The optimal ecophysiological performance (on basis of respiration rates) of the southern group of mussels (M. galloprovincialis) was found around 25 °C, for the Atlantic mussels (M. edulis) around 20 °C and for Baltic mussels (M. trossulus) around 16 °C (and at lower or higher temperatures the growth and decrease). For mussels these data can indicate at which latitude a specific mussel group is expected to survive, or will disappear (i.e. to which extent the distribution range will shift in response to Global Change).

The strategy covers only those issues on which the Self-Government of Pomorskie Voivodeship and its partners in the region have a real impact. 3. The strategy does not include purely local issues unless there is a close relationship between the local needs and potentials of the region and regional interest, or when the local deficits significantly restrict the development opportunities. 4. The strategy does not focus on issues of a routine character, belonging to the realm of the current operation and performing the duties and responsibilities of legal entities operating in the region. 5. The strategy is selective and focused on defining the objectives and courses of action reflecting the strategic choices made. 6. The strategy sets targets amenable to verification and establishment of commitments to specific actions and effects. 7. The strategy outlines the criteria for identifying projects forming part of its implementation. 8. The strategy takes into account the specific conditions for development of different parts of the voivodeship, indicating that not all development challenges are the same everywhere in their nature and seriousness.

    Cambridge University Press 978-0-521-74583-3 - Structural Geology: An Introduction to Geometrical Techniques, Fourth Edition Donal M. Ragan Frontmatter More information STRUCTURAL GEOLOGY An Introduction to Geometrical Techniques fourth edition Many textbooks describe information and theories about the Earth without training students to utilize real data to answer basic geological questions. This volume – a combi- nation of text and lab book – presents an entirely different approach to structural geology. Designed for undergraduate laboratory classes, it is dedicated to helping students solve many of the geometrical problems that arise from field observations. The basic approach is to supply step-by-step instructions to guide students through the methods, which include well-established techniques as well as more cutting-edge approaches. Particular emphasis is given to graphical methods and visualization techniques, intended to support students in tackling traditionally challenging two- and three-dimensional problems. Exer- cises at the end of each chapter provide students with practice in using the techniques, and demonstrate how observations and measurements from the field can be converted into useful information about geological structures and the processes responsible for creating them. Building on the success of previous editions, this fourth edition has been brought fully up-to-date and incorporates new material on stress, deformation, strain and flow. Also new to this edition are a chapter on the underlying mathematics and discussions of uncertainties associated with particular types of measurement. With stereonet plots and full solutions to the exercises available online at www.cambridge.org/ragan, this book is a key resource for undergraduate students as well as more advanced students and researchers wanting to improve their practical skills in structural geology.

    An Investigation of Display Shapes and Projections for Supporting Spatial Visualization Using a Virtual Overhead Map by Catherine Solis A thesis submitted in conformity with the requirements for the degree of Master of Applied Science Graduate Department of Mechanical & Industrial Engineering University of Toronto c Copyright 2020 by Catherine Solis Abstract An Investigation of Display Shapes and Projections for Supporting Spatial Visualization Using a Virtual Overhead Map Catherine Solis Master of Applied Science Graduate Department of Mechanical & Industrial Engineering University of Toronto 2020 A novel map display paradigm named \SkyMap" has been introduced to reduce the cognitive effort associated with using map displays for wayfinding and navigation activities. Proposed benefits include its overhead position, large scale, and alignment with the mapped environment below. This thesis investigates the substantiation of these benefits by comparing a conventional heads-down display to flat and domed SkyMap implementations through a spatial visualization task. A within-subjects study was conducted in a virtual reality simulation of an urban environment, in which participants indicated on a map display the perceived location of a landmark seen in their environment. The results showed that accuracy at this task was greater with a flat SkyMap, and domes with stereographic and equidistant projections, than with a heads-down map. These findings confirm the proposed benefits of SkyMap, yield important design implications, and inform future research. ii Acknowledgements Firstly, I'd like to thank my supervisor Paul Milgram for his patience and guidance over these past two and a half years. I genuinely marvel at his capacity to consistently challenge me to improve as a scholar and yet simultaneously show nothing but the utmost confidence in my abilities.

  • The Position of Madagascar Within Gondwana and Its Movements During Gondwana Dispersal ⇑ Colin Reeves
    Journal of African Earth Sciences xxx (2013) xxx–xxx Contents lists available at ScienceDirect Journal of African Earth Sciences journal homepage: www.elsevier.com/locate/jafrearsci The position of Madagascar within Gondwana and its movements during Gondwana dispersal ⇑ Colin Reeves Earthworks BV, Achterom 41A, 2611 PL Delft, The Netherlands article info abstract Article history: A reassembly of the Precambrian fragments of central Gondwana is presented that is a refinement of a Available online xxxx tight reassembly published earlier. Fragments are matched with conjugate sides parallel as far as possible and at a distance of 60–120 km from each other. With this amount of Precambrian crust now stretched Keywords: into rifts and passive margins, a fit for all the pieces neighbouring Madagascar – East Africa, Somalia, the Madagascar Seychelles, India, Sri Lanka and Mozambique – may be made without inelegant overlap or underlap. This Gondwana works less well for wider de-stretched margins on such small fragments. A model of Gondwana dispersal Aeromagnetics is also developed, working backwards in time from the present day, confining the relative movements of Indian Ocean the major fragments – Africa, Antarctica and India – such that ocean fracture zones collapse back into Dykes themselves until each ridge-reorganisation is encountered. The movements of Antarctica with respect to Africa and of India with respect to Antarctica are defined in this way by a limited number of interval poles to achieve the Gondwana ‘fit’ situation described above. The ‘fit’ offers persuasive alignments of structural and lithologic features from Madagascar to its neighbours. The dispersal model helps describe the evolution of Madagascar’s passive margins and the role of the Madagascar Rise as a microplate in the India–Africa–Antarctica triple junction.

  • Determine Strike and Dip from Two Apparent Dips
    Structural geology - third year Geometrical Projection: Finding True Dip Lab.No.6 /11/2020 True dip: maximum dip angle of a plane measured in vertical section perpendicular to the strike line. Determine strike and dip from two apparent dips Example: A fault trace is exposed in two adjacent cliff faces. In one wall the apparent dip is15°, S50°E, and in the other it is 28°, N45°E (Fig.1-a).What is the strike and dip of the fault plane? Solution: (Fig.1-b) 1-Use the two trend lines, OA and OC, as fold lines .Also, use a vertical line of arbitrary length d. Draw the two trend lines in plan view. 2-From the junction of these two lines (point O) draw apparent dip angle α1 and α2. 3-Draw a line of length (d=h) perpendicular to each of the trend lines to form the triangle COZ and AOX. The value of d must always be drawn exactly the same length because it represents the depth to the layer along any strike line. 4- Triangles COZ and AOX Folded up into plan view with the two apparent-dip trend lines used as fold lines. In Fig.1-b, line AC is horizontal and parallel to the fault plane; therefore it defines the fault's strike. 5-Line OB is then plotted perpendicular to line AC; it represents the direction of true dip. 6-Using line OB as a fold line, triangle BOY (Fig.1-b) can be projected into the horizontal plane, again using length d to set the position of point Y.

Bierson University of California, Santa Cruz C.B. Olkin Southwest Research Institute P.M. Schenk Lunar and Planetary Institute J.M. Moore NASA Ames Research Center K.D. Runyon Johns Hopkins University, Applied Physics Laboratory and The New Horizons Team 1 Abstract The New Horizons spacecraft provided near-global observations of Pluto that far exceed the resolution of Earth-based datasets. Most Pluto New Horizons analysis hitherto has focused on Pluto’s encounter hemisphere (i.e., the anti-Charon hemisphere containing Sputnik Planitia). In this work, we summarize and interpret data on Pluto’s “far side” (i.e., the non-encounter hemisphere), providing the first integrated New Horizons overview of Pluto’s far side terrains. We find strong evidence for widespread bladed deposits, evidence for an impact crater about as large as any on the “near side” hemisphere, evidence for complex lineations approximately antipodal to Sputnik Planitia that may be causally related, and evidence that the far side maculae are smaller and more structured than Pluto’s encounter hemisphere maculae. 2 Introduction Before the 2015 exploration of Pluto by New Horizons (e.g., Stern et al. 2015, 2018 and references therein) none of Pluto’s surface features were known except by crude (though heroically derived) albedo maps, with resolutions of 300-500 km obtainable from the Hubble Space Telescope (e.g., Buie et al. 1992, 1997, 2010) and Pluto-Charon mutual event techniques (e.g., Young & Binzel 1993, Young et al.

Water requirements of ecosystems are mainly represented by minimum hydrobiological or ecological flows, which constitute a limitation to the use of water resources. The main objective of this paper is a comparison, in terms of economic effects of application, of the new ecological flow assessment method with the currently operational hydro-biological flows (RWMB Szczecin method, 2014), and the simplified hydro-biological flow method by Kostrzewa (1977). Another issue is to evaluate whether the ecological flow method is useful and applicable to water balance planning analysis. Computer simulation approach has been used. Calculated hydro-biological and ecological flow volumes were presented along the Wieprza River longitudinal profile and in the selected cross-sections. The time reliability of maintaining the ecological flows as well as changes in volume of available water resources have been used to evaluate economic effects of the new method implementation. It has been proven that the application of ecological flow requirements causes a decrease in the available water resources for both existing and potential water users.
