Marine Sedimentologist - Offshore Core Logging Specialist

Gramian Consulting Group

6d • Remote

About The Position

Gramian Consultancy is seeking an experienced Marine Sedimentologist for a specialized project evaluating and improving AI capabilities in marine geology and sedimentology. The role focuses on scientific validation of marine sedimentology content, offshore core logging, and sediment core descriptions. The specialist will review AI-generated scientific content and provide detailed feedback to improve the accuracy and reliability of AI systems. Previous AI experience is not required.

Candidates must have hands-on experience logging and describing sediment cores at sea aboard research vessels, including offshore core sampling, visual core description, sediment identification, and interpretation of sedimentary structures. General geology experience without direct marine core logging experience is not sufficient.

The project is remote and open globally, excluding Africa and the Middle East.

Requirements

• Academic background in Marine Geology, Marine Sedimentology, Sedimentology, or a closely related earth science discipline.
• Direct professional experience as a Marine Sedimentologist or equivalent specialist.
• Hands-on experience logging and describing sediment cores at sea aboard research vessels.
• Practical experience with offshore marine core sampling and visual core description.
• Strong knowledge of marine sediment identification, lithology, grain-size classification, and sedimentary structures.
• Ability to characterize and interpret sediment and rock layers in marine environments.
• Familiarity with offshore sampling procedures and established core description protocols.
• Strong analytical skills and the ability to review scientific information critically.
• Excellent written communication skills and the ability to explain complex geological concepts accurately.

Responsibilities

• Perform detailed, statement-by-statement validation of marine geology and sedimentology reference answers.
• Evaluate AI-generated content related to marine lithology, sedimentary structures, grain-size classifications, and offshore core sampling protocols.
• Review and validate sediment core descriptions, logging records, and interpretations of marine sediment sequences.
• Assess the identification and characterization of marine sediments, soil layers, and rock formations in ocean-floor environments.
• Apply practical offshore sediment core logging and visual core description experience from research vessels when evaluating technical content.
• Review and annotate marine geology case studies, reference materials, and scientific test sets.
• Identify technical inaccuracies, ambiguities, and edge cases in AI-generated outputs.
• Provide clear, detailed feedback and recommendations to improve scientific accuracy and technical interpretation.
• Document findings and contribute to the continuous improvement of AI training and evaluation materials.
