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

Crustal deformation measurements in Guerrero, Mexico
Kristine M. Larson,Anthony R. Lowry,Vladimir Kostoglodov,Wallis Hutton,O. Sanchez,Kenneth W. Hudnut,Gerardo Suárez +6 more
TL;DR: In this article, GPS measurements of Guerrero were used to calculate interseismic deformation rates and assess the presence and possible location of transient deformation during the period encompassing 1992 to 2001.

Spatiotemporal variations of crustal anisotropy from similar events in aftershocks of the 1999 M7.4 İzmit and M7.1 Düzce, Turkey, earthquake sequences
Zhigang Peng,Yehuda Ben-Zion +1 more
TL;DR: In this article, the authors analyzed spatiotemporal variations of crustal anisotropy along the Karadere-Duzce branch of the North Anatolian Fault from similar earthquakes in the aftershock regions of the 1999 Mw7.4Izmit and Mw 7.1 Duzce earthquakes.
Long GPS coordinate time series: multipath and geometry effects
Matt A. King,Christopher Watson +1 more
TL;DR: In this article, the effects of time-variable satellite geometry and the propagation of an unmodelled multipath signal on GPS coordinate time series are examined and the authors conclude that the time variable nature of GPS observation geometry and satellite orbits combined with a spurious signal that is manifested as an elevation dependent bias can introduce a potential significant contributor to time-correlated noise present in GPS time series.

Electrical conductivity imaging of the Philippine Sea upper mantle using seafloor magnetotelluric data
Kiyoshi Baba,Hisashi Utada,Tada-nori Goto,Tada-nori Goto,Takafumi Kasaya,Takafumi Kasaya,Hisayoshi Shimizu,Noriko Tada,Noriko Tada +8 more
TL;DR: In this paper, the authors performed a three-year seafloor electromagnetic survey in the Philippine Sea, including the western edge of the Pacific Ocean, to image electrical features of a deep mantle slab stagnating in the transition zone and the surrounding mantle in three dimensions (3-D).

Characterization and Petrological Constraints of the Midlithospheric Discontinuity
E. Rader,Erica Emry,Nicholas Schmerr,Daniel A. Frost,Cheng Cheng,Julie Menard,Chunquan Yu,Dennis Geist +7 more
TL;DR: The midlithospheric discontinuity (MLD) is the signature of a chemical interface related to the paleointersection of a volatile-rich solidus and progressively cooling lithosphere as discussed by the authors.

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.
