The effect of ocean acidification on the organic complexation of iron and copper
No full textTrace metal biogeochemistry is projected to be affected by ocean acidification. The understanding of the effects is of particular interest, as trace metals such as Fe and Cu are known for their significant biological roles. Dissolved Fe and Cu in seawater occur predominantly in the form of metal organic complexes. This thesis has investigated the influence that ocean acidification may have on the chemical forms (speciation) of dissolved Fe and Cu in seawater, focusing on their organic complexation, in order to provide a first insight into the possible future changes in their cycling and bioavailability. Competitive Ligand Exchange Adsorptive Cathodic Stripping Voltammetry (CLE-ACSV) was used as an analytical technique throughout this PhD work to determine Fe and Cu organic binding ligand characteristics. Organic Fe complexation was determined at current seawater pH in the high latitude North Atlantic (HLNA), which is an area of climate interest due to the importance of iron limitation on phytoplankton productivity and hence the carbon cycle. Main findings indicate that iron biogeochemistry in surface and subsurface waters of the HLNA is controlled by a combination of phytoplankton iron uptake and microbial iron binding ligand production, whilst in deep waters ligand saturation was evident, suggesting that additional Fe would be removed by scavenging or precipitation. The effect of ocean acidification on organic complexation of Fe and Cu was determined in the northwest European shelf seas, during the first UK Ocean Acidification consortium programme research cruise. Results suggested that a decrease in surface ocean pH will potentially result in a reduction of the free and inorganic metal fraction (Fe'), and also in an increase in the organically complexed iron fraction. Direct impacts on Fe bioavailability, however, are difficult to quantify, as the overall iron solubility, and hence its bioavailability, is controlled by the interrelationship between inorganic solubility, organic complexation, redox chemistry, and phytoplankton-trace metal feedback mechanisms. No significant effects were observed of a decrease in pH on the organically complexed Cu (II) fraction, or on the overall free and inorganically bound fraction (Cu'). Consequently, it is not clear so far whether Cu ligand production will be affected by ocean acidification, or the possible effects on its toxicity. In addition, surface water trace metal distribution in the northwest European shelf seas was assessed. Dissolved metal concentrations of Cd, Cu, Fe, Ni and Zn appeared to be significantly influenced by riverine inputs in the study area; whereas surface seawater pH was not evident as a controlling factor. The diversity of the chemical and biological processes controlling Fe and Cu biogeochemistry, and the way in which they will be altered by ocean acidification, is likely to be complex

Mitificación y desmitificación de La Amazonía en la literatura testimonial de German Castro Caycedo
No full textSe analizan tres novelas del escritor y periodista colombiano, Germán Castro Caycedo: Perdido en el Amazonas, Mi alma se la dejo al diablo y Hágase tu voluntad, con el propósito de estudiar la compleja relación de mitificaciones y desmitificaciones que sobre La Amazonía realiza el autor, por medio de fuentes históricas desde las épocas de la conquista y la colonia, para luego ser ubicadas en el Siglo XX. Esta reflexión es multidisciplinaria, con aportes literarios a través de aspectos históricos, de memoria oral y de antropología, con base en autores como Roland Barthes, Domingo Faustino Sarmiento, Carlos Jáuregui, Julia Kristeva, Homi Bhabha, Bernardo Tovar Zambrano, John Beverley y Hugo Achugar, entre otros.Así, este estudio propone las riquezas y las limitaciones que Castro Caycedo desde la literatura testimonial, escribe sobre temas de civilización, barbarie, centro-periferia, consumismo, culturas aisladas, canibalismo cultural y desnudez. En un contexto que entrelaza testimonio con crónica, reportaje y periodismo, así como la relación entre testimonios orales y escritos, este trabajo aprecia las voces polifónicas divergentes de colonizados y colonizadores, que ilustra una memoria histórica, cultural y simbólica, relacionadas con la Selva Amazónica.Castro Caycedo explora algunos mitos como El Dorado, el Infierno Verde, el chamán y desmitifica los de consumo, homogeneización y turismo. Asimismo, esta investigación manifiesta que los conceptos de hibridez y mestizaje en autores postcoloniales, no son viables para el caso de las culturas no contactadas, como los pueblos indígenas de los huaos y los yuris, revindicando de esta manera las propuestas de resistencia cultural, exilio y resiliencia, como forma digna de supervivencia de estas comunidades en el territorio
Experimental gravity with electromagnetic and gravitational waves
No full textElectromagnetic and gravitational observations can be used to elucidate the nature of compact objects and the fundamental properties of the material in their vicinity. Our ability to extract information about the underlying physics from observations of both electromagnetic and gravitational spectra depends on our understanding of the gravity theory that describes the geometry around these compact objects. For electromagnetic observations, we must also understand the complex astrophysics that produces the observed radiation. In this dissertation, we describe our efforts to constrain and detect deviations from general relativity using: the electromagnetic radiation emitted by an accretion disk around a black hole; the gravitational waves produced when comparable-mass black holes collide; and we have also studied chaotic signatures that could appear when a small compact object falls into a supermassive object during an extreme mass-ratio inspiral. Our analyses combined relativistic ray-tracing and Markov Chain Monte Carlo sampling techniques, as well as analytical and numerical calculations of the motion of particles. We found that even when a simple astrophysical model for the accretion disk is assumed a priori, the uncertainties and covariances between the parameters of the model and the parameters that control a deviation from general relativity make tests of general relativity very challenging when applied to accretion disk spectrum observations. We also found that current gravitational wave observations place constraints on metric deformation parameters that are more stringent than what can be achieved with current X-ray instruments. Based on our numerical findings when studying extreme mass-ratio inspirals, we conjecture that the geodesics of the as-of-yet unknown exact solution for spinning black holes in a dynamical Chern-Simons theory is integrable. Consequently, we predict the existence a fourth integral of motion associated with the exact solution. The work presented in this thesis advances the development of both analytic calculations and computational simulations to test our understanding of gravity’s fundamental properties with electromagnetic and gravitational waves.Submission original under an indefinite embargo labeled 'Open Access'.
