Descripción: Dissolved Oxygen (DO) is involved in important biogeochemical reactions, such as the aerobic respiration of microbes, rock-weathering or contaminant degradation. The general view is that the deeper subsurface of continents is mostly anoxic. However, recent observations have shown that cracks in rocks can allow oxygen to reach deeper down, thus extending deeper the influence of oxygen in biogeochemical reactions. Here, we present a modeling framework validated with field data to understand and predict the hydrological and geological controls on DO evolution in silicate catchments, shedding new light on its influence on rock-weathering and microbial life in the continental subsurface. Resumen: El oxígeno disuelto (OD) interviene en importantes reacciones biogeoquímicas, como la respiración aeróbica de los microbios, la meteorización de las rocas o la degradación de contaminantes. La idea generalizada es que el subsuelo más profundo de los continentes es mayoritariamente anóxico. Sin embargo, observaciones recientes han demostrado que las grietas en las rocas pueden permitir que el oxígeno llegue a mayores profundidades, ampliando así la influencia del oxígeno en las reacciones biogeoquímicas. En este trabajo presentamos un marco de modelización validado con datos de campo para comprender y predecir los controles hidrológicos y geológicos sobre la evolución del OD en las cuencas de rocas silicatadas, mejorando así nuestra comprensión sobre su influencia en la meteorización de las rocas y la vida microbiana en el subsuelo continental.

In an inexplicable worldwide event, forty-seven extraordinary children were spontaneously born to women who'd previously shown no signs of pregnancy. Millionaire inventor Reginald Hargreeves adopted seven of the children; when asked why, his only explanation was, "To save the world." These seven children form the Umbrella Academy, a dysfunctional family of superheroes with bizarre powers. Their first adventure at the age of ten pits them against an erratic and deadly Eiffel Tower, piloted by the fearsome zombie-robot Gustave Eiffel. Nearly a decade later, the team disbands, but when Hargreeves unexpectedly dies, these disgruntled siblings reunite just in time to save the world once again. * This volume collects the first six-issue series, as well as out-of-print short stories and an expanded sketchbook section featuring work by Gabriel Ba, James Jean, and Gerard Way. * "Flawless...stylish, imaginative."--Newsarama * Listed as one of the Top Ten Great Graphic Novels for Teens by the Young Adult Library Service Association (YALSA). * Amazon.com's #1 Graphic Novel of 2008! * A New York Times bestseller!
