What kind of figure this source publishes

The BLS category is a relative rank, not an absolute level, and it is not a first-hand measurement: it groups an occupation's percentile ranks across several published studies into four bands. It is not an employment or wage forecast, not a probability of adoption, and it does not separate automation from augmentation.

Values in this tab are predicted labels, not observations. Eloundou et al. (2023) published two rating regimes — human raters and GPT-4 — and the β shown here is derived from the GPT-4 rater basis alone; the same task can take a different value under the other regime. The unit and the meaning differ from the observed shares (%) in the other tabs, so do not place them on the same axis.

Occupation information

ILO

ILO occupational description

Geologists and geophysicists

Geologists and geophysicists 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 exploration and extraction, water conservation, civil engineering, telecommunications and navigation, and assessment and mitigation of the effects of development and waste disposal projects on the environment.

Tasks

(a) conducting research and improving or developing concepts, theories and operational methods related to geology and geophysics;
(b) studying composition and structure of the Earth's crust, examining rocks, minerals, fossils and other materials to determine processes affecting the development of the Earth, trace evolution of past life, establish nature and chronology of geological formations and assess their commercial applications;
(c) interpreting research data and preparing geological reports, maps, charts and diagrams, reports and papers;
(d) applying geological knowledge to problems encountered in civil engineering projects such as the construction of dams, bridges, tunnels, and large buildings; and land reclamation projects;
(e) using various remote sensing programmes to investigate and measure seismic, gravitational, electrical, thermal, and magnetic forces affecting the Earth;
(f) estimating weight, size and mass of the Earth and composition and structure of its interior, and studying the nature, activity and predictability of volcanoes, glaciers and earthquakes;
(g) charting the Earth's magnetic field and applying this and other collected data for broadcasting, navigation and other purposes;
(h) studying and measuring physical properties of seas and the atmosphere and their inter-relationship, such as the exchange of thermal energy;
(i) locating and determining the nature and extent of oil, gas and mineral deposits using seismological, gravimetric, magnetic, electrical or radiometric methods;
(j) identifying deposits of construction materials and determining their characteristics and suitability for use as concrete aggregates, road fill or for other applications;
(k) researching the movement, distribution and physical properties of ground and surface waters;
(l) advising in areas such as waste management, route and site selection and the restoration of contaminated sites.

ESCO occupational vocabulary

mine geologistESCO 2114.1.6
Mine geologists locate, identify, quantify and classify mineral resources and their geological characteristics and structure. They provide advice to mine managers and engineers at existing and prospective mineral operations.
oceanographerESCO 2114.1.8
Oceanographers study and perform research on matters related to the sea and oceans. Oceanographers divide their expertise in four main 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, marine biologists whose focal point is the study of living organisms, ecosystems and their interaction underwater, and geological oceanographer whose research refers to the bottom of seas and their plaques.
hydrologistESCO 2114.1.5
Hydrologists research and study the quality, current challenges, and distribution of water in the Earth. They study water supply from rivers, streams, and springs to determine their adequate and sustainable use. Together with a cross functional team of professionals, they plan and develop how water can be supplied to cities and urban areas while ensuring efficiency and resource conservation.
hydrogeologistESCO 2114.1.4
Hydrogeologists in mining study the distribution, quality and flow of water in order to keep mine workings free of nuisance water and to ensure an adequate supply of process water. They supply and evaluate information which will protect ground and surface water from contamination.
palaeontologistESCO 2114.1.9
Palaeontologists research and analyse forms of life that existed in ancient eras of the planet Earth. They strive to define the evolutionary path and the interaction with different geological areas of all kinds of once organisms and such plants, pollen and spores, invertebrate and vertebrate animals, humans, traces such as footprints, and ecology and climate.
mineralogistESCO 2114.3
Mineralogists study the composition, structure and other physical aspects of the earth. They analyse various minerals and use scientific equipment to determine their structure and properties. Their work mostly focuses on the classification and identification of minerals by taking samples and performing further tests, analysis and examinations.
environmental geologistESCO 2114.1.1
Environmental geologists study how mineral operations may impact the composition and physical characteristics of the earth and its resources. They provide advice on issues such as land reclamation and environmental pollution.
geophysicistESCO 2114.2
Geophysicists study the physical characteristics of the earth and apply physical measurements to geological situations. Geophysicists use the principles of gravity, seismicity and electromagnetics to identify the structure and composition of the earth.
exploration geologistESCO 2114.1.2
Exploration geologists examine and prospect for mineral deposits. They identify, define and obtain legal title to an economically viable mineral deposit. They are responsible for design, management and execution of the exploration programme.
seismologistESCO 2114.1.10
Seismologists 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.
geologistESCO 2114.1
Geologists research the materials that form the earth. Their observations depend on the purpose of the research. Depending on their specialisation, geologists study how the Earth has been shaped over time, its geological layers, the quality of minerals for mining purposes, earthquakes and volcanic activity for private services, and similar phenomena.
geochemistESCO 2114.1.3
Geochemists study the characteristics and chemical elements in minerals, rocks and soils, and how they interact with hydrological systems. They coordinate the collection of samples and indicate the suite of metals to be analysed.
