TLDR
The Global Multi-Resolution Topography (GMRT) as discussed by the authors is a collection of bathymetry tiles with digital elevations and shaded relief imagery spanning nine magnification doublings from pole to pole.Abstract:
[1] Seafloor bathymetric data acquired with modern swath echo sounders provide coverage for only a small fraction of the global seabed yet are of high value for studies of the dynamic processes of seafloor volcanism, tectonics, mass wasting, and sediment transport that create and shape the undersea landscape. A new method for compilation of global seafloor bathymetry that preserves the native resolution of swath sonars is presented. The Global Multi-Resolution Topography synthesis consists of a hierarchy of tiles with digital elevations and shaded relief imagery spanning nine magnification doublings from pole to pole (http://www.marine-geo.org/portals/gmrt). The compilation is updated and accessible as surveys are contributed, edited, and added to the tiles. Access to the bathymetry tiles is via Web services and with WMS-enabled client applications such as GeoMapApp®, Virtual Ocean, NASA World Wind®, and Google Earth®.read more

TL;DR: In this paper, the authors review the geodynamic evolution of the Aegean-Anatolia region and discuss strain localisation there over geological times, and they favour a model where slab retreat is the main driving engine, and successive slab tearing episodes are the main causes of this stepwise strain localization and the inherited heterogeneity of the crust is a major factor for localising detachments.
