Oceanographer study and perform research on matters related to the sea and oceans. Oceanographers divide their expertise in different branches of research which are physical oceanographers whose research focus on waves and tides, chemical oceanographers whose study address the chemical constitution of sea waters, and geological oceanographer whose research refers to the bottom of seas and their plaques.

Geophysicist, Geomorphology conduct research, improve or develop concepts, theories and operational methods, or apply scientific knowledge relating to geology and geophysics in such fields as oil, gas and mineral exploitation, water conservation, civil engineering, telecommunications and navigation. They assess development projects and the effects of waste disposal on the environment.

Geophysicist, Seismology study the movement of tectonic plaques in the Earth which causes the propagation of seismic waves and earthquakes. They study and observe the various sources causing earthquakes such as volcanic activity, atmospheric phenomena, or the behaviour of oceans. They provide their scientific observations to prevent dangers in construction and infrastructure.

Geomagnetician &nbsp;sets up magnetic observatories and stations in order to chart the Earth's magnetic field and applies data obtained to problems for examples in the fields of telephony, telegraphy, radio broadcasting, navigation, mapping, and geophysical prospecting. Also called terrestrial magnetician.<br>&nbsp;

Hydrogeologist conduct research on the location, movement, and quality of water formations that are below the surface of the Earth.

Hydrologist conduct research on the distribution, circulation, and physical properties of the earth's underground and surface waters.

Paleontologist studies the fossilized remains of all kinds of organisms (plants, animals, fungi, bacteria and other single-celled living things), and is interested in knowing the history of organic life on earth.

Stratigraph examines layers in the soil or rock to determine how the land came to be and in what sequence.

Petroleum Geoscientist evaluate gas and oil fields. They design and develop methods for extracting oil and gas from underneath the earth's surface. They maximise the recovery of hydrocarbon at a minimum cost, pursuing minimal impact on the environment.

Geoscientist Study the composition, structure, and other physical aspects of the Earth. May use geological, physics, and mathematics knowledge in exploration for oil, gas, minerals, or underground water; or in waste disposal, land reclamation, or other environmental problems. May study the Earth's internal composition, atmospheres, and oceans, and its magnetic, electrical, and gravitational forces. Includes mineralogists, paleontologists, stratigraphers, geodesists, and seismologists.

Well Site Geologist supervise every stage of the drilling process for extracting gas and oil. They study and analyse rocks from the oil and gas wells in order to direct the drilling, and identify the rock formation into which They are drilling.They assess development projects and the effects of waste disposal on the environment.

Reservoir Geologist responsible in all stages of the development of a well, including identification of potential locations to drill and assisting the drilling team with work associated with the oil well. They assess development projects and the effects of waste disposal on the environment.

Structural Geologist investigating the structure and evolution of the earth and its natural resources. planning programmes for exploration of sites for oil, gas, water, minerals, and related. They assess development projects and the effects of waste disposal on the environment.

Physical Oceanographer study water, sea life, weather and climates, which helps preserve the natural resource of oceans and coastal waters, as well as contributes to other professionals' ability to predict weather patterns and care for wildlife. They assess development projects and the effects of waste disposal on the environment.

Seismic Interpreter use a variety of technical, computational and scientific modelling techniques to produce geophysical and geological data that can be used to analyse the hydrocarbon content of rock structures.

Geological Specialist are expert in applying geological knowledge for the assessment of sites, soils, slope stability, sediments and other observable characteristics in the Earth. They integrate this information in the planning and development of projects in those places. They assess and answer questions concerning the geological characteristics of soils by performing research and experiments on the sites aimed to be intervened.

Geophysical Specialist &nbsp;is a professional who specializes in geophysics, a branch of Earth science that focuses on the study of the Earth's physical properties through the use of physical principles. Geophysical Specialists use a variety of methods and technologies to investigate the subsurface and understand the Earth's internal structure.

Geoscience Officer Grade C41 works in the field of geoscience, which encompasses various branches of Earth science, including geology, geophysics, geochemistry, and environmental science. The job description for a Geoscience Officer can vary depending on the employer, industry, and specific focus of the role

Geomechanic preparing rock, soil and water samples for testing. They analyse the chemical and physical properties of samples.

Sedementologist examine certain rock types, but usually soil from a variety of areas (including sand and silt). They assess development projects and the effects of waste disposal on the environment.
