La observación y el contacto directo con la realidad, según Jesús Fernández, son el mejor modo de contrastar los modelos teóricos y comprobar si casan con aquella. Con este principio abordó el estudio de amplios espacios geograficos que, en definitiva, nutrieron el libro Geomorfologia estructural (2006). En su conjunto, el libro esta repleto de aportaciones ineditas sobre el relieve de amplios sectores de las cordilleras Cantabrica, Iberica y Betica. Sin embargo, la verdadera innovacion no se limita al dar a conocer hechos particulares, sino en elevarlos a la categoria de conceptos generales en la concepcion de teorias sobre la formacion del relieve. El trabajo constituye un exhaustivo y pormenorizado analisis de cada uno de los elementos que componen el relieve de cada espacio geografico se convierte en la herramienta fundamental: el estudio de cada espacio geografico se ha basado, por asi decirlo, en hechos reales, en la observacion.

Rocks and mountains have withstood aeons of life on our planet gradually eroding shifting solidifying and weathering We might spend a little less time on earth but humans are also weathering evolving and changing as we re transformed by the shifting climates of our lives and experiences So what might these ancient natural forms have to teach us about resilience and change In a stunning exploration of our own connection to these enduring forms outdoor psychotherapist and geologist Ruth Allen takes us on a journey through deep time and ancient landscapes showing how geology which has formed the bedrock of her own adult life and approach to therapy can offer us a new way of thinking about our own grief change and boundaries In a world shaken by physical political and medical disasters Weathering argues for a deeper understanding of the ground beneath our feet to better serve ourselves and the world we live in

What will remain of our plastic cans and other junk long after humans have vanished What kind of fossils will we leave as relics into the far future A blizzard of new objects has suddenly appeared on Earth plastic bottles ballpoint pens concrete flyways outsize chicken bones aluminium cans teabags mobile phones T shirts They re produced for our comfort and pleasure then quickly discarded The number of our constructions has exploded to outweigh the whole living world This new made treasure chest underpins our lives But it is also giving a completely new style of fossilization to our planet as hyper diverse and hyper rapidly evolving technofossils spin out of our industrialized economy Designed to resist sun wind rain corrosion and decay and buried in soils seafloor muds and the gigantic middens of our landfill sites many will remain petrified as future geology What will these technofossils look like in future rock How long will they last and how will they change as they lie underground for decades then millennia then millions of years Discarded describes how they transform as they are attacked by bacteria baked by the Earth s inner heat squashed by overlying rock permeated by subterranean fluids crumpled by mountain building m

A revelatory journey from the tin mines of Cornwall to the gold mountains of Georgia in search of the substances which have both shaped our imagination and imperilled our very existence

Artificial Intelligence in Earth Science Best Practices and Fundamental Challenges provides a comprehensive step by step guide to AI workflows for solving problems in Earth Science The book focuses on the most challenging problems in applying AI in Earth system sciences such as training data preparation model selection hyperparameter tuning model structure optimization spatiotemporal generalization transforming model results into products and explaining trained models In addition it provides full stack workflow tutorials to help walk readers through the whole process regardless of previous AI experience The book tackles the complexity of Earth system problems in AI engineering fully guiding geoscientists who are planning to implement AI in their daily work

Una serie de trabajos que comentan en torno divulgativo, con desarrollo axhaustivo de la metodología científica, varios temas introductorios en Geología Costera: el marco dinámico de la costa de Huelva, algunos estuarios andaluces y cantabricos, la aplicacion de tecnicas de teledeteccion y ejemplos de regeneracion de playas.

Esta obra se ha concebido como una introducción a los estudios de geofísica basada en la dilatada experiencia docente de sus autores, Agustín Udías y Julio Mezcua. Siguiendo criterios pedagógicos, los Fundamentos de geofisica estan organizados en tres bloques -Gravimetria, Sismologia y Geomagnetismo-, a los que se han añadido capitulos sobre otras materias fundamentales, como la Induccion electrica, la Geotermia, a Radiactividad y el Magnetismo externo. Cada unidad culmina con una seleccion bibliografica sobre los temas tocados, donde se reseñan algunas obras generales, asi como textos mas especializados. Al final del libro, se incluyen una serie de apendices con informaciones utiles (vectores y tensores, coordenadas esfericas, ecuacion de Laplace y armonicos esfericos, unidades del SI, los parametros de la Tierra y la division interna de esta), asi como un repertorio de problemas y ejercicios sin resolver que complementan el estudio de los temas tratados.
