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.

Instrument: Please select an instrument first and then a particular survey and/or bounding box.
Surveys: Include one or by default all surveys. Latest surveys are listed first.

or optionally find surveys by searching survey/voyage details, investigator name, survey region etc

Data Process Status: Data in higher levels of processing will also be selected.
Depth range: - optionally apply the following depth range filter
from to metres

Regions: You can select regions from the pre-defined sets below or draw your own bounding-box region. Choose from:


Hold down the Ctrl key and draw a box. Clicking anywhere on the map will remove an existing box.
Select a Region
Select from the MarLIN 'Oceans and Seas'
Bounding box
