MULTIBEAM BATHYMETRY
SINGLEBEAM BATHYMETRY
High resolution bathymetry with 100% coverage of the seafloor through
multibeam echo-soundings and course correction, pitch, roll, yaw, and
sound velocity.
Bathymetric studies with dual-frequency and single-frequency echo
sounders that allow greater precision in all types of aquatic floors.
PRODUCTS
MAGNETOMETRY
SIDE SCAN SONAR
It allows the detection of ferrous materials that are found on the seabed
either on the surface or buried in the area being studied. This is determined
by the anomalies detected at Nanotesla (nT) level.
Technology that allows the creation of acoustic images of the surface of
the seabed, as well as carrying out georeferencing and characterization
of decks, detection and search of objects, inspection of structures and
monitoring of marine works.
PRODUCTS
SUB-BOTTOM PROFILING
CURRENT METER
Methodology of geophysical exploration based on the principles of vertical reflection
physics, with this method low frequency acoustic records, reflected in the marine
subsoil that allow to discriminate the interfaces between different layers of materials
are obtained. We have high resolution “pinger” and “boomer” type profilers of greater
power.
We have this instrument to measure the speed of the current in the
sea, rivers and other bodies of water, we have equipment such as
the Acoustic Doppler Current Profiler (ADCP) and propeller-type
meters for different types of studies.
With ADCP technology we can also measure wave height after a
series analysis of the data.
PRODUCTS
MARINE ELECTRICAL TOMOGRAPHY
MARINE SAMPLING
It is a multi-electrode resistivity method, based on 2D terrain modeling using
numerical techniques. This allows identifying lithologies and morphologies of
the subsoil, as well as locating objects.
We have Vibro Corer, Gravity Corer, Grab Corer and other equipment
to help classify and describe samples taken from the seabed.
PRODUCTS
CTD´s, MULTIPARAMETER PROBES AND TIDE GAUGES
GPS’s
They allow measuring different variables and parameters, such as:
oceanographic conductivity, temperature, depth, salinity, density,
and dissolved oxygen, etc.
We have different high-precision positioning technologies with
Omnistar XP or ground-based (RTK) satellite corrections for
maximum reliability in achieving data accuracy.
PRODUCTS
MARINE EQUIPMENT
SOFTWARE
Geomares has different equipment for the development of marine works
such as: winches, cranes, compressors, generators, dredging and suction
pumps, four-point anchoring systems, cable motors, and burial equipment
for submarine cable.
We have specialized software for different types of hydrography as well
as marine geophysical equipment, which allow us to make the best use
of the data obtained in order to develop final products adjusted for
different segments such as Oil & Gas, Telecommunications, and Engineering
amongst others.

PORT STUDIESOur services range from the characterization of the sea bed and
sea bottom areas as well as the coastal area for the construction
of new ports to studies for maintenance and verification of port
structures. Port geophysical studies are vital for piling planning
and cost reduction in the port construction phase.
.
Through the combination of technologies including multibeam bathymetry,
side scan sonar, sub-bottom profiler and magnetometry we determine
the existence of shipwrecks and other archaeological findings which is
indispensable for obtaining the permits from ICANH and other entities for
port, submarine cable and pipeline projects, Oil & Gas, and general dredging
in marine environments, they also help in the determination of the state and
hthe necessary tools for the rescue of wrecks and other marine artifacts.
SOLUTIONS
We perform pre-dredge and post-dredge marine geomorphological
characterization which allows us to calculate dredging volumes with
high accuracy, and taking into account the characterization of materials
performed with t he sub-bottom profiler and bottom samples such as
vibrocorer and others; it is possible to determine the optimal type of
dredging needed for each area, performing the environmental study of
the type of material and its components for the dump area thus
permitting planning and cost reduction.
DREDGING: PLANNING ANDCONTROL
COASTAL ENGINEERINGWe conduct studies of marine dynamics that allow us to
make models designed for different types of coastal
projects. These studies help to prevent the impacts of
coastal erosion, and develop the realization of artificial
beach projects, piers, and other coastal protection works.

POSITIONING OFPLATFORMS AND OIL STRUCTURES
CURRENT AND SEDIMENTTRANSPORT STUDIES
It is vital for the determination of different projects in rivers, reservoirs
and coastal zones. Through the use of technologies such as current
meters, liquid and solid amphorae and hydrodynamic models we
can determine factors such as the useful life of reservoirs, coastal
erosion and littoral sedimentation phases, in addition to sediment
calculations in navigation channels in rivers and ports.
SOLUTIONS
Throught precision centimetric GPS and specialized navigation
software, Geomares provides positioning services for barges
and oil structures with the safety required by the OIL & GAS
and others from the engineering sector.
CALCULATION OF AREA AND VOLUME FOR RESERVOIRS
NAVIGABILITY STUDIESThe bathymetry and sedimentology in rivers and navigation
channels allows us to carry out nautical cartography besides
performing the analysis of navigability of the bodies of water.
SOLUTIONS
With the use of single beam, and multibeam bathymetry and LiDAR
topography, we perform the precise calculation of volumes and
characteristic levels required in hydroelectric projects, lakes, and
dams in order to comply with CNO requirements and to foresee the
useful life of the reservoirs.
SOLUTIONSSUBMARINE CABLES
Route study for submarine cables and pipes
Shore End Landing, installation and maintenance of
Submarine cables
ROUTE STUDY FOR SUBMARINE CABLES AND PIPELINES
SOLUTIONS
With the combination of multibeam bathymetry, sub-bottom
profiling, side scan sonar, magnetometry and sea bed
sampling, we have studied ideal routes for laying cables and
underwater pipelines, as well as the profile and tools
needed for its burial.
Geomares manages international standards in terms of
data acquisition and quality and presentation in GIS, CAD
and other formats required by the industry’s clients.
Our specialized equipment can detect submarine cables,
cperform geo-location, and find intersections on new routes.
SHORE END LANDING, INSTALLATION AND MAINTENANCE OF SUBMARINE CABLES
SOLUTIONS
Geomares has the capacity, experience and the necessary equipment for the
the landing, installation and burial of submarine cables. We have experience
in burial under difficult conditions and shallow water including burial in
different seabed materials such as sand, rock, clay and silt.
Due to our strategic location and operation capacity, we are an efficient
solution for the maintenance of submarine cables in case of damages caused
by incidents with anchors, and climatic or technical factors. We handle
turnkey solutions that adjust to the times needed for a rapid deployment
allowing repairs to be made in the shortest possible time avoiding greater
losses for the cable operator.
We have an operating license in Colombia that streamlines procedures and
times for installation and maintenance of submarine cable, making
pre-operational times and costs efficient when compared to foreign
competitors.

in work, GEOMARES SAS maintains all the areas of performance
updated according to Quality, Safety and Environment, seeking to
cover the legal, ethical and professional needs demanded by the
national and international market. That is why we comply with
sound policies in the prevention and promotion of health by
contemplating the management system on the premises of
sustainable development for environmental care and analysis of
factors that affect health.
Our QHSE objectives are achieved thanks to the assimilation and
proactive understanding of the company's general QHSE policy,
its Management System, and the continuous improvement of this
policy. Each project implements the QHSE Management System
