Our solutions at your service

In g3eo we focus in high-resolution seafloor mapping, hydrocarbon seep imaging and characterization, and the generation of seafloor maps such as bathymetry, textural, geomorphology and geology which are the result of detailed seafloor reconnaissance surveys. To accomplish such tasks, we deliver the following services:



It represents the submarine relief. We specialize in singlebeam and multibeam (known as three-dimensional bathymetry) acquisition, processing and interpretation work.


Seismic reflection

It characterizes the subsurface geometry. We specialize in singlechannel and multichannel seismic acquisition, processing and interpretation work (such as chirp, boomer, sparker, airgun).


Sidescan sonar

It images seafloor textures and man-made objects. We specialize in single-frequency and multi-frequency sidescan sonar acquisition, processing and interpretation work.



It differentiates seafloor strata and man-made objects based on their magnetic properties. We specialize in single-sensor and multi-sensor magnetometry acquisition, processing and interpretation work.

sediment sampling

Sediment sampling

It is used to recover unconsolidated sediments from the seafloor, lakes and coastal areas. We specialize in offshore and onshore sampling systems such as dredges, piston corers, power shovels, augers, penetrometers.

sediment analyses

Sediment analyses

It is used to determine physico-chemical conditions from substrata in natural and man-made habitats. We specialize in laboratory work such as granulometry, mineralogy, organic matter, fauna characterization.


Geodatabase design

It is used to store, handle, evaluate, and retrieve geodata efficiently for summary reports and geospatial investigations. We specialize in the design and management of geodatabases.


Geodata analyses

It solves spatial queries through the association of data types and attributes. We specialize in the development and implementation of algorithms to predict environmental conditions.

adcp ctd


It measures the physico-chemical properties in the water column. We specialize in CTD systems (such as rosette wheels), ADCP systems (such as anchored, towed by ships) and Niskin bottles.
