The published record, and the data library.
Two decades of peer reviewed papers, and an archive of existing survey data browsable by location and type. Depth is the resource.
A bibliography that runs 2000 to 2023.
The gravity section alone lists about 57 entries, published in PNAS, Geophysical Research Letters and The Leading Edge, and presented at ASEG, EAGE, SEG and KEGS venues. Recurring SGL authors include S. Elieff, S. Ferguson, L. Sander and S. Sander. A 2023 PNAS paper carries SGL data into Petermann Glacier melt rate research.
Existing surveys, ready to license.
SGL's archive of flown surveys is indexed by location and by data type. For a block that has already been flown, the fastest survey is the one already in the library: gravity, magnetic, electromagnetic and radiometric data gathered over decades of operations on every continent.
Ask about a specific block and SGL will confirm coverage, vintage and licensing terms directly.

The field photography archive behind these operations spans Africa, Antarctica, Asia and Oceania, Canada, Europe, Greenland, the Middle East, South America and the United States, organised on the current site under Photos.
Evidence first, then conversation.
The papers establish the method. For a block, a dataset, or a new survey, the contact page routes each kind of enquiry to the right inbox.
