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

TL;DR: The Campeche province as mentioned in this paper consists of numerous 20 to 40 m high coral ridges that are developed in intermediate water depths of 500 to 600 m. The rich coral community is dominated by the framework-building scleractinia Enallopsammia profunda and Lophelia pertusa.

Seismic attenuation beneath northeastern Japan: Constraints on mantle dynamics and arc magmatism

TL;DR: In this paper, a three-step approach was applied to estimate three-dimensional (3-D) P wave attenuation structure under northeastern Japan, where the spectral-ratio method for S-coda waves was used to determine the corner frequencies of earthquakes and the whole-path attenuation terms, t*, and site-amplification factors were simultaneously estimated by a joint inversion.

Interaction between forearc and oceanic plate at the south‐central Chilean margin as seen in local seismic data
Abstract: We installed a dense, amphibious, temporary seismological network to study the seismicity and structure of the seismogenic zone in southern Chile between 37° and 39°S, the nucleation area of the great 1960 Chile earthquake. 213 local earthquakes with 14.754 onset times were used for a simultaneous inversion for the 1-D velocity model and precise earthquake locations. Relocated artificial shots suggest an accuracy of the earthquake hypocenter of about 1 km (horizontally) and 500 m (vertically). Crustal events along trench-parallel and transverse, deep-reaching faults reflect the interseismic transpressional deformation of the forearc crust due to the subduction of the Nazca plate. The transverse faults seems to accomplish differential lateral stresses between subduction zone segments. Many events situated in an internally structured, planar seismicity patch at 20 to 40 km depth near the coast indicate a stress concentration at the plate's interface at 38°S which might in part be induced by the fragmented forearc structure.

Evolution of a Length Polymorphism in the Human PER3 Gene, a Component of the Circadian System
TL;DR: The variation in allele frequencies between indigenous populations did not show a pattern that would indicate selective pressure on PER3resulting from day-length variation or mean annual insolation, and the allele-frequency difference between European Americans, African Americans, and East Asians was not an outlier when compared to the distribution for presumed neutral SNPs.

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.
