Use this form to search for multibeam data. You must first pick an instrument and then either select a survey (or use a search term) and/or pick a region by name or by bounding box. If you wish to find data from other instruments then repeat the search. Some instruments are only on a few voyages. Use the map tool at the bottom to show the extents of the data for an instrument. The more you enter the more restrictive the search will be so you may need to generalise the search if you do not initially find any data.
Note this tool is limited to obtaining about 2Gb of data or less. Please contact GSM if you expect to exceed this limit.
