* Maintain daily field logs, acquisition reports, and safety documentation

* Perform real-time QA/QC of geophysical and geotechnical data acquisition

* Operate and oversee acquisition of marine survey systems, including:

* Chirp sub-bottom profilers

* Sidescan sonar

* Magnetometers

* Seismic reflection systems (single-channel and multi-channel preferred)

* Marine vibracore systems and other geotechnical samplers

* Acquire, process, and interpret integrated geophysical and geotechnical datasets

* Prepare maps, figures, and technical reports for engineering, regulatory, and scientific applications

* Support data processing and interpretation workflows using industry-standard software

* Mentor junior staff and assist with training and development in both field and office settings

* Support survey planning, logistics, and proposal development as needed

Basic Qualifications:

* Bachelor of Science degree (or higher) in geology, geophysics, oceanography, or a related field

* 4+ years of relevant marine geoscience experience

* Experience supporting marine geophysical surveys using:

* Chirp sub-bottom profiler

* Sidescan sonar

* Magnetometer

* Experience with marine geotechnical sampling, including vibracores or similar systems

* Experience with geophysical acquisition and interpretation software (e.g., Sonar Wiz, Hypack, Discover or equivalent)

* Strong technical writing and organizational skills

* Ability and willingness to support extended offshore rotations (typically 10-14 days) in physically demanding environments

Preferred

* Prior experience acting as a Field Party Chief or senior field lead on offshore surveys

* Experience with multi-channel seismic acquisition and interpretation

* Experience with survey planning and vessel mobilization

* Familiarity with GIS and mapping software (e.g., ArcGIS, AutoCAD, Surfer)
