Assess whether the reasoning meets professional standards for the stated task. Write reference answers and scoring criteria grounded in geoscience observations, models, sampling, and environmental interpretation. Explain consequential errors, evidence gaps, and the reasoning behind your corrections. This is remote, project-based contract work. Scope, hours, and assignments depend on project matching; the listed hourly range applies to matched work.
