Introduction

MB-System is an open source software package for the processing and display of bathymetry and backscatter imagery data derived from multibeam, interferometry, and sidescan sonars. This software is distributed freely (and for free) in the form of source code for Unix platforms. The heart of the system is an input/output library called MBIO which allows programs to work transparently with any of a number of supported swath sonar data formats. This approach has allowed the creation of "generic" utilities which can be applied in a uniform manner to sonar data from a variety of sources. Most of the programs are command-line tools, but the package does include graphical tools for editing swath bathymetry, editing navigation, modeling bathymetry calculation, and adjusting survey navigation.

The acronym MB stands for MultiBeam; this reflects the fact that the early development of MB-System focused on processing deep sea data from multibeam sonars. However, MB-System now supports several data formats from sidescan and interferometric sonars and works with data from all depth ranges.

The National Science Foundation (NSF) has been the primary supporter of MB-System development. NSF initially provided grants to the authors at the Lamont-Doherty Earth Observatory in 1993 (two years), and 1995 (five years). SeaBeam Instruments also contributed significant effort from 1994 to 1999. This support was renewed through two parallel five year grants (2001-2006, 2006-2011) to Caress at the Monterey Bay Aquarium Research Institute (MBARI) and to Chayes at Lamont. MBARI, with support from the Packard Foundation, has matched the NSF support as part of its seafloor mapping program.

The original NSF mandate was to create a set of generic tools which would work with all of the sonar data used in NSF-supported projects. Not surprisingly, the core of the MB-System user community consists of NSF-supported researchers at U.S. institutions such as the Lamont-Doherty Earth Observatory, the Scripps Institution of Oceanography, and the Woods Hole Oceanographic Institution. However, MB-System has also come to be used widely in the international marine geological community.

The MB-System source code is distributed under the GNU General Public License as formulated by the GNU Project. MB-System installation depends on some other software packages (e.g. GMT and netCDF ), all of which are freely available as source code.

This documention is distributed with and refers to MB-System release 5.2.1880.
