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

Low seismic velocities below mid‐ocean ridges: Attenuation versus melt retention
TL;DR: In this paper, the authors evaluate whether seismic attenuation can reconcile subridge seismic structure with low melt fractions, which is at odds with low productivity and high melt mobility inferred from petrology and geochemistry.

A surface wave analysis of seismic anisotropy beneath eastern North America
TL;DR: In this article, the authors evaluated the nature of upper-mantle seismic anisotropy in central and eastern North America using the phase velocities of surface waves traversing the length of the MOMA broadband array.
Hydrographic Atlas of the World Ocean Circulation Experiment (WOCE). Volume 3: Atlantic Ocean
TL;DR: Koltermann et al. as mentioned in this paper presented a comprehensive global hydrographic survey of physical and chemical properties, of unprecedented scope and quality, and represents the "state of the oceans" during the 1990s.

Seismic imaging of the lithosphere beneath Hudson Bay: Episodic growth of the Laurentian mantle keel
TL;DR: In this paper, the authors used surface wave tomography to illuminate new details of the lithospheric architecture of the Hudson Bay region, resolving both seismic wavespeed and azimuthal anisotropy.

Seismic attenuation tomography of the Northeast Japan arc: Insight into the 2011 Tohoku earthquake (Mw 9.0) and subduction dynamics
TL;DR: In this paper, a 3D model of the crust and upper mantle under the entire Northeast Japan (Tohoku) arc from the Japan Trench to the Japan Sea coast is determined using a large number of high-quality t* data measured precisely from P and S wave spectra of local earthquakes.

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.
