The honest hard part

You'll spend weeks at a time on survey vessels in rough seas, far from home. The work is physically demanding and sometimes dangerous. Once ashore, you're stuck processing data indoors. The field work is seasonal and project-based, so job security depends on government funding and shipping industry contracts. There aren't many positions, so you may need to move states or spend years casual before landing permanent work.

Where the jobs are

Regional river and lake survey work happens where development projects run, but these are temporary contracts. Remote work is not an option in this role.
