Abstract. We present PALEOSTRIPv1.0, a MATLAB open-source software designed to perform 1D, 2D and 3D backtracking of paleo-bathymetries. PALEOSTRIP comes with a Graphical User Interface (GUI) to facilitate computation of sensitivity tests and to allow the users to switch on and off all the different processes and thus separate the various aspects of backtracking. As such, all physical parameters can be modified from the GUI. It includes 3D flexural isostasy, 1D thermal subsidence and possibilities to correct for prescribed sea level and dynamical topography changes. In the following we detail the physics embedded within PALEOSTRIP and we show a few applications on a drilling site (1D), a transect (2D) and a map (3D), taking the Ross Sea (Antarctica) as a case study. PALEOSTRIP has been designed to be modular and to allow user to insert their own implementations.

Short summary
PALEOSTRIP has been developed in the framework of past Antarctic ice sheet reconstructions for periods during which bathymetry around Antarctica differed substantially from today. It has been designed for users with no particular knowledge in numerical modeling and allows users to switch on and off the processes involved in backtracking/backstripping. Applications are broad and it can be used to restore any continental margin bathymetry or sediment thickness as well as to perform basin analysis.
