MB-System was originally developed at the Lamont-Doherty Earth Observatory of Columbia University (LDEO) and is now a collaborative effort between the Monterey Bay Aquarium Research Institute (MBARI) and LDEO. The National Science Foundation has provided the primary support for MB-System development since 1993. The Packard Foundation has provided significant support through MBARI since 1998. Additional support has derived from SeaBeam Instruments (1994-1997), NOAA (2002-2004), and others.
