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

Seismic anisotropy reveals the long route of the slab through the western-central Mediterranean mantle
TL;DR: In this article, the authors used seismic anisotropy fast directions as a proxy for the present and past mantle flow to reconstruct the past kinematics of the subduction process.

Hydrological response to earthquakes in the Haibara well, central Japan – I. Groundwater level changes revealed using state space decomposition of atmospheric pressure, rainfall and tidal responses
TL;DR: In this paper, time series analysis using state-space modeling is applied to extract hydrological anomalies related to earthquakes. But, the results show that ground motion due to earthquakes is not the major cause of the water level drops and that the contribution from static strain is rather small.

Water mass analysis for the U.S. GEOTRACES (GA03) North Atlantic sections
TL;DR: In this paper, the authors present the distributions of hydrographic properties (potential temperature, salinity, dissolved oxygen, and micromolar level inorganic macronutrients) along two sections occupied in the subtropical North Atlantic as part of the first US GEOTRACES (GA03) survey during 2010 and 2011.

Northern Hemisphere temperature patterns in the last 12 centuries
TL;DR: This paper analyzed the spatio-temporal patterns of temperature variability over Northern Hemisphere land areas, on centennial time-scales, for the last 12 centuries using an unprecedentedly large network of temperature-sensitive proxy records.

Evaluation of the first GOCE static gravity field models using terrestrial gravity, vertical deflections and EGM2008 quasigeoid heights
TL;DR: In this article, the spectral enhancement method (SEM) was applied to the truncated gravity field and steady-state ocean circulation Explorer (GOCE) data to make their spectral content more comparable with the terrestrial data and the results from both assessments together provide strong evidence that the first 2 months of GOCE observations improve the knowledge of the Earth's static gravity field at spatial scales between ~125 and ~110 km.

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.
