Hydrographic Surveyor
Role lens
Hydrographic surveyors measure and map, by means of specialised equipment, marine environments. They collect scientific data in order to study the underwater topography and morphology of bodies of water.
Hydrographic surveyors are specialists in measuring and mapping marine environments. Your work involves collecting scientific data to understand the underwater topography and morphology of oceans, lakes, and rivers. This data is crucial for a variety of applications, including safe navigation for ships, coastal management, resource exploration, and scientific studies. You’ll operate specialized equipment, analyze data, and produce accurate charts and reports.
- • Operating and maintaining hydrographic survey equipment, such as multibeam echosounders, side-scan sonars, and GPS systems.
- • Collecting bathymetric (depth) data, sediment samples, and other relevant information.
- • Processing and analyzing data to create accurate charts, maps, and 3D models of underwater terrain.

About this source›
Source: ELA/EURES labour shortages and surpluses. Readings are published at occupation-group level, and cover Europe. Editions differ in annex layout and country coverage, so a change between years does not always mean the labour market changed. Countries in grey were not reported, which is not the same as being in balance.
What these words mean
The four things this section reports
- Reported demand
- Whether employers report needing people in this job — a judgement published by a national or EU body, not a count.
- Where it is heading
- Which way employment in this job is expected to move over the coming years, from an official projection.
- Openings
- Roughly how many openings arise — from growth and from people leaving the job.
- Typical pay
- What people in this job typically earn where the source publishes it. Blank does not mean unpaid; it means nobody publishes it for that place.
A measure is left out when nobody publishes it for that place, rather than shown as zero.
Which way the market leans for you
- In your favour
- More openings than people looking — employers are competing for candidates.
- Balanced
- Openings and candidates are roughly matched.
- Competitive
- More people looking than openings — expect to compete.
- Mixed evidence
- Sources disagree, or the same occupation group is short in one part and oversupplied in another.
Every source resolves to one of these four, so there is a single vocabulary to learn. What differs is the evidence behind it, which is printed underneath each verdict — a measured ratio of openings to jobseekers, or an assessment published by a national body.
How this job compares with other jobs in the same country
- Strong
- Among the strongest in that country
- Good
- Stronger than most jobs in that country
- Mixed
- About typical for that country
- Weak
- Weaker than most jobs in that country
This is a rank within one country, not a score you can carry across borders — the registers behind two countries count different people, so the same number means different things in each. It is also why a job can be among the strongest in a country and still show as Competitive: it leads the field in a market that is crowded overall.
Where these come from
Every figure is published by a national statistics office, a public employment service or an EU body, and each card names its source and the period it covers. Some places are counted monthly, others assessed once or twice a year, so two places on the same map can be describing different moments — the date is always shown.
None of this predicts one person’s chances. It describes a market.

Future Outlook for hydrographic surveyor
The outlook for hydrographic surveyor reflects a balanced mix of automation exposure and durable, human-led work.
How are these scores calculated?
The Resilience Score (0–100) estimates how structurally protected this occupation is from automation and AI disruption, based on task-level analysis. Higher scores mean more human-judgment-intensive tasks. AI Exposure shows the estimated percentage of task hours that current AI capabilities could affect. These are model-derived structural indicators, not predictions about individual job security.
How could hydrographic surveyor change as AI adoption grows?
Several task areas may shift toward AI-assisted workflows, so reskilling becomes more important.
