Position: Shallow Marine Geophysicist

Qualification: Degree in Geoscience or Geophysics.

Location: Work from home in UK, Ireland, Australia, Canada


XOCEAN is an ocean data company – we collect data for clients ranging from mapping the seabed to monitoring the environment. However, we do this differently, instead of using conventional crewed survey ships, we have developed a marine robotic system known as an Uncrewed Surface Vessel (USV).


Responsible for geophysical data collection, processing, interpretation and reporting.

Main Duties & Responsibilities

Responsibilities will include:

  • Remote data acquisition and processing of MBES, Side-scan Sonar, & shallow Sub-bottom Profiler (Innomar) sensors.
  • Side scan sonar data processing including seabed picking, interpretation, production of mosaic and seabed features
  • Shallow SBP (Innomar) processing and interpretation.
  • Magnetometer data processing.
  • Data processing and quality control of all survey geophysical data, creating final deliverables to a high standard.
  • Survey System Setup – hardware and software configuration prior to vessel mobilisation on a project.
  • Online surveying on projects in shifts.
  • Quality Control – monitoring of the data being captured using online and offline survey tools.
  • Report writing and client interaction.

On occasion this role may involve:

  • Support with bathymetry data acquisition and processing
  • Support Lead Geophysicist with Survey Planning
  • Managing and maintaining Quality, Environment and Health and Safety standards including update, implementation and management of all ISO processes as appropriate to the role.
  • Implementing, maintaining, managing and updating all standard operating procedures and processes appropriate to the role.

Requirements: Essential Skills / Attributes and Experience

  • Degree in Geoscience or Geophysics.
  • Acquisition and processing experience of MBES, Side-scan Sonar, & Shallow sub-bottom Sensors.
  • Experience in one or more of Chesapeake SonarWiz, DUG Insight and Oasis Montaj processing software packages.
  • Sidescan Sonar processing experience to include seabed picking; target ID, tagging and listing; the creation and export of navigationally and gain corrected mosaics. Production of seabed features based on SSS, MBES and backscatter.
  • Innomar data processing to include SEGy conversion/tidal reduction and export, band-pass and denoise filtering, acoustic-gain control, interpretation and export of subsurface horizons and contact hyperbolas.
  • Magnetometer processing to include filtering and processing of the navigation; the creation of residual, analytical signal and altitude grids, and the production of a final target listing and project specific deliverables.
  • 3 years Marine Survey Experience.
  • Strong computer literacy (Configuration of sensor equipment required).
  • Enthusiastic, positive and proactive nature with a keen attention to detail.

Desirable Experience

  • Experience in bathymetry data acquisition and processing.
  • Experience of marine survey data acquisition and processing software (e.g. QINSy, Qimera, EIVA etc)
  • ARC GIS and AutoCad knowledge would be an advantage.
  • Relevant marine qualifications such as Yachtmaster, Coastal Skipper, ICC (or equivalent).


  • Applicants must demonstrate how they meet the essential criteria. Desirable criteria may be used for further shortlisting.
  • We thank all candidates for their interest, however due to very high volumes, only those who are selected for further consideration, will be contacted directly.
