TLDR
GMT allows users to manipulate (x,y,z) data, and generate PostScript illustrations, including simple x-y diagrams, contour maps, color images, and artificially illuminated, perspective, and/or shaded-relief plots using a variety of map projections.Abstract:
Version 31 of the Generic Mapping Tools (GMT) has been released More than 6000 scientists worldwide are currently using this free, public domain collection of UNIX tools that contains programs serving a variety of research functions GMT allows users to manipulate (x,y) and (x,y,z) data, and generate PostScript illustrations, including simple x-y diagrams, contour maps, color images, and artificially illuminated, perspective, and/or shaded-relief plots using a variety of map projections (see Wessel and Smith [1991] and Wessel and Smith [1995], for details) GMT has been installed under UNIX on most types of workstations and both IBM-compatible and Macintosh personal computersread more

Are rupture zone limits of great subduction earthquakes controlled by upper plate structures? Evidence from multichannel seismic reflection data acquired across the northern Ecuador–southwest Colombia margin
Jean-Yves Collot,Boris Marcaillou,Françoise Sage,François Michaud,William Agudelo,Philippe Charvis,David Graindorge,Marc-André Gutscher,George D. Spence +8 more
TL;DR: In this article, the authors propose a model of weak transverse faults which reduce coupling between adjacent margin segments, together with a splay fault and an asperity along the plate interface as controlling the seismogenic rupture of the 1958 earthquake.

Seafloor geomorphology of the SW Barents Sea and its glaci-dynamic implications
TL;DR: In this article, a 3D reflection seismic imaging technique was used to identify large-scale submarine geomorphic features produced by former ice sheets, including elongated ridge-groove features, interpreted to be glacial bedforms produced by fast-flowing grounded glaciers.
Journal ArticleDOI
Agulhas leakage into the Atlantic estimated with subsurface floats and surface drifters
TL;DR: In this paper, surface drifters and subsurface floats were used to study the pathways of warm, salty Indian Ocean water leaking into the South Atlantic that is a component of the upper limb of the Atlantic meridional overturning circulation (MOC).

Phenomenology of deep slow earthquake family in southwest Japan: Spatiotemporal characteristics and segmentation
TL;DR: In this article, the authors investigated the phenomenology of deep slow earthquakes, including low-frequency tremors, very low frequency earthquakes, and short-term slow slip events, on the subducting plate interface in southwest Japan.
Journal ArticleDOI
A global-scale plate reorganization event at 105−100 Ma
TL;DR: In this paper, the authors investigate tectonic events from the period ∼110 to 90 million years ago and show that the reorganization occurred between 105 and 100 million years, was global in scale, and affected all major plates.

Free software helps map and display data
Paul Wessel,Walter H. F. Smith +1 more
TL;DR: The Generic Mapping Tools (GMT) is introduced, which is a free, public domain software package that can be used to manipulate columns of tabular data, time series, and gridded data sets and to display these data in a variety of forms ranging from simple x-y plots to maps and color, perspective, and shaded-relief illustrations.
