Task exposure index for this occupation
Averaged across the week, this work sits at the high end of the exposure scale. O*NET breaks Geoscientists, Except Hydrologists and Geographers into 29 distinct work activities. Weighted by how much of the week each one takes, 76% of the job sits at or above the threshold where current systems can do the task end to end. The single largest contributor is "Locate natural resources using geospatial or other environmental data", which scores 78 and takes roughly 10% of the week. That is the average for the job title. It is not a measurement of any particular person’s week, and the difference between the two is usually larger than the difference between job titles.

What this occupation does
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.

How far off the rest is
Of those 29 activities, 14 can be performed by systems available today and 4 are outside what current approaches do at all. The remaining 11 sit in between — demonstrated in research or in narrow products, but not something you can hand over whole. We do not put dates on that middle group, because nobody can.

Why your own number is different
Two people with the title "Geoscientists, Except Hydrologists and Geographers" can spend their weeks on almost entirely different parts of this list, and the parts they choose move the number far more than the title does. Who signs off when the work is wrong, whether the job needs you physically present, and how fast you have picked up the tools all change it again — and none of that is in an occupation average.
The assessment asks you to divide your own week across these activities and answer fourteen questions about the parts of the job an occupation average cannot see. It takes six to nine minutes.

Questions
Will AI replace Geoscientists, Except Hydrologists and Geographers?
We do not answer that, because nobody can. What is measurable is how much of the work is already doable by machine: for Geoscientists, Except Hydrologists and Geographers, about 76% of a typical week, across 29 activities. The other 24% is not, and what happens to the job depends on things this index does not contain — cost, regulation, who carries the liability, and what the people doing it decide to do next.
What part of this job is most exposed?
"Proofread documents, records, or other files to ensure accuracy" — it scores 88 out of 100 on task automatability and takes roughly 4% of the week.
What part is least exposed?
"Inspect work sites to identify potential environmental or safety hazards", at 28 out of 100. Work like that is where the hours you protect tend to be worth the most.
Where do these numbers come from?
The activity list and the time weights come from O*NET 30.3, the US Department of Labor's occupational database. The exposure score for each activity is ours, from a published model — the weights, the priors and the limitations are all on the methodology page. No language model is involved in the arithmetic.
Does this apply to my job?
Only roughly. This is the average for the title, and the number that matters is the one for the week you actually work. The assessment asks you to divide your own time across these activities and answer fourteen questions about accountability, the parts of the job that need you specifically, and how fast you have adapted. That produces a different number, and usually a more useful one.
