Many months ago, the destroyer Zafirah vanished during the same event that sent the cruise liner Ghazali crashing into the Hamura star.
Now she is back, in a time when both the aftermath of the Mysticides and the death of the Emissary have shaken the horizon to its foundations. The Coriolis Council and Zenithian authority are questioned, and more and more people revolt against their oppressors. The throat of the Third Horizon is exposed, and this is when something ancient rises from the shadows. This book contains:.
Price: Approx. This product consists of two double-sided full-color maps, depicting five important adventure landscapes featured in Coriolis — The Last Cyclade. The heavy aroma of incense and sugared dates spreads from the Market Square on the Coriolis space station.
At first glance, nothing seems out of place. But the calm is deceptive. A veiled emissary, a representative of powerful lifeforms residing in the depths of the gas giant Xene, has arrived at the station with strange tidings. The Council of Factions, always so outspoken, has gone dead silent. The Third Horizon is entering a new era, still unknown, shrouded in darkness. Will the future be revealed by the light of the Icons, or by the roaring firestorms of war?
The Mercy of the Icons campaign lets the gaming group experience and influence a universally disruptive shift in the history of the Third Horizon, a period of time when a new era is born out of the corrupt and pain-stricken corpse of what has been.
This method is referred to as lidar, or airborne laser swath mapping ALSM in the case of aerial surveys.
High-resolution swath bathymetry uses sonar for the same types of measurements in marine environments. With lidar, a laser pulse is sent from the instrument, and the time for its return from a reflected surface is detected and used to calculate distance. Current technology permits typical accuracies to about 5 to 10 centimeters vertically and 20 to 30 centimeters horizontally, with data returns every few decimeters. From these returns a point cloud of elevation data is created; various analytical methods are then used to distinguish vegetation from ground Figure 1.
For the first time, we now can obtain surveys over broad areas that document topography at the resolution at which transport, erosion, and deposition processes operate. Lidar data also capture important quantitative attributes of vegetation that can be used in studies. Area in red box on the digital air photo is the area covered by the upper lidar images.
Landslide scars, channel banks, river terraces, floodplain features, fault traces, and other landforms can be detected, quantified, and used to advance theoretical and practical understanding. Repeat scans allow change detection as never previously possible. These techniques also permit improved understanding of the human impact on types and rates of geomorphic processes. To quantify rates of Earth surface processes and ages of landforms, Earth scientists have developed in the past 20 years a wide range of tools that exploit the time-dependent exposure of materials to cosmic rays, heat, and light.
The greatest breakthrough came when measurement techniques advanced to the stage that trace concentrations of atoms produced by cosmic rays could be isolated and measured accurately Box 1. Questions posed by early twentieth century Earth scientists about ages of landscapes and their evolutionary sequences, and the underlying mechanisms of erosion and deposition, can now be addressed quantitatively. These rate measurements coupled with new thermochronometers see Box 2.
Interdisciplinary research 2 in Earth surface processes comprises the detailed investigation of contemporary processes that generate and degrade landscapes and change the properties of rocks and soil; the definition of how these processes have functioned over the long periods of time required for the evolution of surface conditions composition, function, and form ; the deep connections among surface processes, climate, tectonics, life, and human activity; and ultimately the prediction of future landscapes and the fluid, solid, and solute fluxes across them.
Evidence of the environmental history of landscape development is stored in the geologic and geochemical records of sediments, water, and soils. Building from datasets that extend across space and time and using a growing variety of powerful tools and techniques, scientists are able to measure landforms, probe sediments and. As interdisciplinary approaches increase the power of landscape research, a complex picture is beginning to emerge of landscape functioning, evolution, and interactions with life and human activity.
Research in this area is integrative because it involves linkages to many related fields and because the core of the research lies at discovering the interactions and feedbacks involving physical, chemical, biological, and human processes. Notably, the NSF-supported Critical Zone Observatories, which have grown out of this interest in the Critical Zone, are an integral part of the effort to advance the understanding of processes operating at the surface of the Earth see Box 2.
To identify most effectively the greatest challenges and most promising opportunities in Earth surface processes, the committee sought input in its public meetings from panelists whose expertise augmented that of committee members Appendixes A and B and remained abreast of the meeting activities of a parallel, but separate, NRC study Strategic Directions in the Geographical Sciences.
The committee also sought input from a broad section of the international scientific community relevant to Earth surface processes through an online questionnaire see Appendix B. Although this report focuses on the terrestrial surface, the committee emphasizes that research on the submarine surface and on marine processes is as active and exciting as terrestrial research.
However, without any marine scientists on the committee, we did not have the resources to do justice to topics addressed by this important, allied community. Numerous boxes and figures throughout the report are designed to highlight specific concepts, tools, and examples related to Earth surface processes research that otherwise are. Earth is bombarded constantly by high-energy cosmic rays such as protons and neutrons.
The target atoms are abundant in rock, soil, and the atmosphere. The rates of production and decay of many cosmogenic nuclides are known sufficiently well that measured nuclide concentrations in samples can, among other things, be used as an absolute dating technique. The production of cosmogenic nuclides in a wide range of Earth materials and knowledge of the production rates have led to a revolution in our ability to quantify the timing and rates of Earth surface processes from thousands to millions of years with radiogenic nuclides 7 Be, 10 Be, 14 C, 26 Al, 36 Cl , or even longer with stable nuclides 3 He, 21 Ne , in a diverse range of environments and over a wide range of time scales see figure below.
Examples of exposure age dating include dating glacial moraines to quantify the timing and magnitude of ice ages, dating of groundwater to understand long-term migration velocities and the effects of climate changes on recharge, and dating of fluvial terraces, alluvial fan surfaces, and landslide deposits to investigate the effects of tectonic processes on crustal deformation, faulting, and erosion processes see figure below.
Denudation rates or magnitudes can be quantified by measuring nuclide concentration in modern or ancient fluvial sediments for catchment average rates or from bedrock samples at points across a landscape. The ages of sediments can now be documented to within a few years over the last two centuries, and sediments from individual floods can be identified during the following season. More recently, cosmogenic nuclide concentrations in soils have been used to understand the rates and magnitudes of soil mixing due to biologic and periglacial processes and soil production rates from bedrock.
Accelerator mass spectrometry AMS is required for measurement of most radionuclides. NSF, and other science programs globally, have committed funds to the development and maintenance of AMS facilities. The future of cosmogenic isotope geochemistry is promising. Examples of frontiers in this field include 1 refinement of nuclide production rates through the United States and European Cosmic-Ray produced NUclide Systematics on Earth CRONUS and CRONUS-EU initiatives to reduce uncertainties in exposure age and denudation rate calculations, 2 development of significantly smaller and more affordable AMS facilities to reduce costs and increase sample throughput, and 3 continued development and application of cosmogenic noble gas techniques to a wider range of minerals.
Of particular interest is recent progress in measuring cosmogenic 3 He in common mineral phases that are present in many rocks and are more retentive of helium than quartz.
Dating landforms and determining fault slip rates. Different ages of alluvial fan deposits form surfaces with varying degrees of surface roughness, desert varnish, and other indicators of relative age.
Cosmogenic dating, in this case 10 Be, provides chronologic control for different ages of alluvial fan surfaces offset along the northern Death Valley fault fault strikes northwest to southeast along the western part of a lidar-derived bare-Earth topographic image. The development of these fans has been linked to changes in climate.
The age estimates of these features are used to reconstruct the offset fan surfaces along the fault in order to calculate a slip rate of 4. Neither these boxes nor the examples in the body of the text can represent the entire range of research covered by the field, but they are intended to draw attention to contributions from various disciplines to further research on Earth surface processes.
Similarly, we do not cite many specific research publications from among the vast number in this area of research except to provide proper attribution for a point of fact, a figure, a direct quotation, or an explicit concept. The committee also notes that the study charge is focused on research and, for this reason, has deliberately not included education and human resource issues in its discussion.
Although clearly of importance to all areas of science and engineering, capturing education and workforce topics in adequate detail was beyond the study scope. Appendix D provides some background to the growth in this field at universities and in the international professional community.
In addition to the collaborative and integrative approaches emphasized in this report, the committee recognizes that the emerging science of Earth surface processes often has relied on fairly simple, descriptive approaches. Nevertheless, significant advances will require developing quantitative predictive capability for how landscapes form, evolve, and respond to change.
Such capability is especially important as Earth surface processes are increasingly altered by human activity and climate change. For the foreseeable future and for most landscape processes, predictive models will of necessity continue to be partially empirical, even as improvements in understanding underlying processes gradually are achieved.
A useful analogy here is one of weather forecasting, which combines sophisticated numerical solutions of the governing equations of atmospheric dynamics with empirical relations for incompletely understood processes e. Although the underlying equations for landscape evolution are not known at present and may be quite diverse, the general approach to landscape prediction is likely to be similar.
Intended for use by NSF, decision makers, and research communities in academia, the private sector, and federal agencies, this report identifies high-priority areas for research in Earth surface processes. Many of the research areas address critical societal needs and issues.
The report also suggests means to coordinate and support the necessary research. Many of the exciting research activities and intellectual advances in the study of Earth surface processes, however, have gone beyond traditional disciplinary boundaries of Earth science, reaching into research domains that fall within other areas at NSF, such as climate, ecosystem sciences, tectonic processes, and.
Increasingly, as the human impact strengthens, the field of Earth surface processes requires integration with the social and behavioral sciences as well. Understanding the processes by which that habitat has been created and continually altered is important to determine the causes of environmental degradation, to restore what is degraded, and to guide policy decisions toward a sustainable Earth surface.
This acknowledgment now puts a responsibility on the shoulders of natural scientists as well as professionals in economics, social science, engineering, and other fields to interpret the record of ongoing environmental change and to anticipate and, in some cases, make quantitative predictions of future events or conditions.
We have the technological ability to monitor closely human impacts on the environment. The need to observe, measure, and model human-landscape interactions in an integrated, predictive fashion is clear. To develop this capability, fundamental research is needed to understand and quantify the impact and feedback relationships between human activity and Earth surface processes.
In many cases, the socioeconomic will and capacity exist to attempt to alter the impacts and responses initiated in human-influenced landscape systems. With new scientific questions about various components of the Earth system, opportunities and tools for research, rapid growth of the human population, and unprecedented changes in biota, land cover, process rates, and global climate, an appraisal of the study of Earth surface processes is both timely and crucial.
During geologic spans of time, Earth's shifting tectonic plates, atmosphere, freezing water, thawing ice, flowing rivers, and evolving life have shaped Earth's surface features. The resulting hills, mountains, valleys, and plains shelter ecosystems that interact with all life and provide a record of Earth surface processes that extend back through Earth's history.
Despite rapidly growing scientific knowledge of Earth surface interactions, and the increasing availability of new monitoring technologies, there is still little understanding of how these processes generate and degrade landscapes.
Landscapes on the Edge identifies nine grand challenges in this emerging field of study and proposes four high-priority research initiatives. The book poses questions about how our planet's past can tell us about its future, how landscapes record climate and tectonics, and how Earth surface science can contribute to developing a sustainable living surface for future generations.
