Generic Mapping Tools (GMT) is an open‐source software package for the analysis and display of geoscience data, helping scientists to analyze, interpolate, filter, manipulate, project, plot time series gridded data sets. The GMT toolbox includes about 80 core 40 supplemental program modules sharing a common set command options, file structures, documentation. Its power process produce publication‐quality graphic presentations has made it vital large scientific community that now more than...
Abstract The Generic Mapping Tools (GMT) software is ubiquitous in the Earth and ocean sciences. As a cross‐platform tool producing high‐quality maps figures, it used by tens of thousands scientists around world. basic syntax GMT scripts has evolved very slowly since 1990s, despite fact that generally perceived to have steep learning curve with many pitfalls for beginners experienced users alike. Reducing these means changing interface, which would break compatibility existing scripts. With...
Abstract The GMT/MATLAB toolbox is a basic interface between MATLAB ® (or Octave) and GMT, the Generic Mapping Tools, which allows users full access to all GMT modules. Data may be passed two programs using intermediate structures that organize metadata needed; these are produced when modules run. In addition, standard matrix data can used directly as input improves interoperability widely tools in geosciences extends capability of both tools: gains powerful computational capabilities while...
In this paper we present a new magnetic compilation for an area of the North Atlantic located between 35°N and 47°N up to anomaly 33r. We also strategy pick isochrones compute finite rotation poles. This technique is based on continuous reduction pole some basic assumptions regarding direction remanent magnetization vector. A cost function that measures misfit interpreted rotated systematic exploitation parameter space used best set Eulerian rotations chrons 5, 6, 6C, 11–12, 13, 18, 20, 21,...
Analysis of sea surface temperature (SST) time series since 1960 from existing data bases shows a generalized warming trend in the northern Canary upwelling system. The field satellite‐derived SST trends off Western Iberia was built at pixel scale (4 × 4 km) for period 1985–2008, revealing significant spatial differences rates. Weaker fit to known pattern southern part Iberia, pointing out intensification this feature 1985, particularly during peak summer months. A more regular behavior is...
Earthquake catalogs for the Iberian Peninsula report three strong- magnitude events in eighteenth century: 27 December 1722, 1 November 1755, and 31 March 1761. These have magnitudes greater than 7 generated tsunamis that damaged Portuguese coasts. However, their source areas are controversial because of lack detailed coherent historical descriptions. The 1761 earthquake was felt Lisbon at noon, alarming inhabitants throwing down ruins past 1755 earthquake. According to several sources...
Abstract To date, a lack of reliable morphological and geophysical data has been major limitation to understanding the tectonic magmatic processes that shape Azores Triple Junction Terceira Rift. This situation changed recently: for first time both areas are covered by high-quality swath bathymetry surveys marine magnetic with GPS quality positioning. provides good description surface morphology, also chrons give fundamental information timing spreading in geological frame. There is large...
Abstract. The M ∼ 8.3–8.4 25 November 1941 was one of the largest submarine strike-slip earthquakes ever recorded in Northeast (NE) Atlantic basin. This event occurred along Eurasia–Nubia plate boundary between Azores and Strait Gibraltar. After earthquake, tide stations NE a small tsunami with maximum amplitudes 40 cm peak to through Madeira islands. In this study, we present re-evaluation earthquake epicentre location using seismological data not included previous studies. We invert travel...
The lack of accurate and detailed magnetic information has, in the past, limited development well constrained models for plate tectonic evolution Azores Triple Junction. An aeromagnetic survey, made possible by existing airport facilities, has long been desired as it can provide high quality data, whose homogeneity coherency is far better than those provided classic marine surveys. results presented this paper concern only a part Aeromagnetic Survey conducted Portuguese Instituto Nacional de...
