Meteorological Officer Grade C41 responsible for issuing weather forecasts, issuing warnings, monitor and release earthquake and tsunami information so that property damage and loss of life can be reduced, analyze changes in weather conditions professionally and identify impact as well as how to reduce the impact, analyze weather survey charts and conduct research on weather phenomenon to reduce the impact of bad weather. Provides quality advisory services efficiently and effectively to meet customer needs and stakeholders' expectations for increase the socio-economic activities of the people and the state.

Meteorologist conduct research, improve or develop concepts, theories and operational methods related to the composition, structure and dynamics of the atmosphere and prepare detailed or long-term weather forecasts used in aviation, shipping, agriculture and other areas and for the information of the general public.

 Climatologist study the average change in weather and climate from a long-term perspective. They research and analyse historic weather conditions in order to forecast climatic conditions trends such as changes in temperature, global warming, or regional evolutive weather conditions. They use these findings for advising on environmental policy, construction, agricultural projects, and societal matters.

Meteorologist-Weather Forecasting study climate processes, measure and predict weather patterns and provide consultancy services to a variety of weather information users. They work out models for weather forecasting, develop instruments to collect meteorological data and compile statistics and databases.

Seismologist Carry out tasks investigating the phenomena of the earth, the causes and effects of seism earth activities by using seismography and other tools.

Weather Forecaster gather meteorological data. They predict the weather according to these data. Weather forecasters present these forecasts to the audience via radio, television or online.

Meteorologist, Environmental studies weather patterns and the impact that atmospheric conditions and weather systems have on human habitats and the environment as a whole. 

Meteorologist, Numerical Weather Prediction Modeling conduct research, improve or develop concepts, theories and operational methods related to the composition, structure and dynamics of the atmosphere and prepare detailed or long-term weather forecasts used in aviation, shipping, agriculture and other areas and for the information of the general public.

Geochemist provide assistance in the exploration of natural resources, such as oil, natural gas and minerals. They use their expertise to reduce pollutants and increase water quality.

Geologist is in charge of studying natural formations and the earth’s processes to promote environmental conservation or safe land development. Geologist alsoconduct 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.

Geologist, Marine conduct research studies to understand how events in the Earth's crust under the ocean affect the environment.

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.
