La reacción de Belousov-Zhabotinsky se comporta como un sistema no lineal oscilante que es posible modular y reproducir siguiendo procedimientos experimentales previamente establecidos. El cambio temporal de los distintos componentes de la reacción da lugar tanto a la visualización de un cambio de color de la disolución como a la formación de patrones espaciales y estructuras disipativas que evolucionan y se modifican en el tiempo. La reacción global puede describirse como la oxidación del ácido malónico por bromato en presencia de un catalizador como el cerio en su estado oxidado y bromuro como intermediario. Este proceso genera productos como ácido bromomalónico, dióxido de carbono y agua.

Based on several tools (SEM, EBSD, laser confocal microscopy and FE-SEM) we present original data relative to the microstructure and texture of aragonite crystallites in all Glycymeris shell layers (crossed-lamellar, complex crossed-lamellar, fibrous prismatic and pedal retractor and adductor myostraca) and address texture characteristics at the transition from one layer to the other, identifying similarities and differences among the different layers. Shells were cut transversely, obliquely and longitudinally in order to obtain different orientated sections of the outer and inner layer and of the myostraca. The identification of major microstructural elements was provided by detailed SEM and laser confocal microscopy images. Microstructure and texture characterization was based on EBSD measurements presented as band contrast images and as color-coded crystal orientation maps with corresponding pole figures. Crystal co-orientation was measured with the MUD value. Finally, the distribution of the organic matrix occluded within the outer crossed-lamellar layer was revealed using FE-SEM. These data, besides providing a modern unaltered Glycymeris reference to detect diagenetic alteration in fossil analogs used for paleoenvironmental reconstructions, are useful to better comprehend the mechanisms of bivalve shell formation., 2017 Italian Ministry PRIN RX9XXY Project, Instituto de Salud Carlos III Spanish Government CGL2017-85118-P, Unidad Cientifica de Excelencia of the University of Granada UCE-PP2016-05, Junta de Andalucia RNM363

Ocean bottom seismometers were provided by the U.S National Oceanographic Instrument Pool. This publication reflects only the authors' views. The European Commission is not responsible for any use that may be made of the information it contains., Deception Island volcano (Antarctica) is one of the most closely monitored and studied volcanoes on the region. In January 2005, a multi-parametric international experiment was conducted that encompassed both Deception Island and its surrounding waters. We performed this experiment from aboard the Spanish oceanographic vessel 'Hesperides', and from five land-based locations on Deception Island (the Spanish scientific Antarctic base 'Gabriel de Castilla' and four temporary camps). This experiment allowed us to record active seismic signals using a large network of seismic stations that were deployed both on land and on the seafloor. In addition, other geophysical data were acquired, including bathymetric high precision multi-beam data, and gravimetric and magnetic profiles. To date, the seismic and bathymetric data have been analysed but the magnetic and gravimetric data have not. We provide P-wave arrival-time picks and seismic tomography results in velocity and attenuation. In this manuscript, we describe the main characteristics of the experiment, the instruments, the data, and the repositories from which data and information can be obtained., MINECO/FEDER TEC2015-68752-R, KNOWAVES, Spanish Education and Research Ministry REN 2001-3833 CGL2005-05789-C02-02/ANT POL2006-08663 CGL2008-01660, National Science Foundation (NSF) ANT-0230094 NSF-1521855, European project MED-SUV - European Union's Seventh Framework Program 308665, European project EPOS, European Union (EU) 676564
