Analisis geoestadistico de la temperatura del fondo de los margenes continentales europeos y zonas adyacentes

This BSc Thesis presents a geostatistical analysis of bottom temperature data from Europeancontinental margins aimed at the study of gas hydrates. For this reason, the analysisfocuses on water masses below 200 m depth, where gas hydrates are usually stable. Abovethis bathymetric depth, the study of bottom temperature is no longer of interest sincehydrates, in mid-latitudes, are usually not stable.The present analysis has been developed following the following steps: Spatial segmentation of the data: Based on the subdivision of the oceanicmasses into deep water masses, the characteristics of each zone and theirpossible effect on gas hydrate stability have been defined. Analysis of the covariance of the data, assessing the use of statistical methods. Error analysis: Analysing the fit of the estimated values for the model oncethe interpolation method has been applied. Estimation of the bottom temperature: Making a bottom temperature map ofeach of the water masses.The work reveals a great spatial continuity of the vast majority of the deep water masses.The deeper water masses show more homogeneous data than the water masses affectingthe mid-upper slope and continental shelf. However, most of the water masses located onthe mid-upper slope and continental shelf show more homogeneous data than the watermasses affecting the mid-upper slope and continental shelf.
