SCHISM Modeler/ Oceanographer

Closing Date: January 15, 2022

The Columbia River Inter-Tribal Fish Commission’s (CRITFC) Coastal Margin Observation and Prediction (CMOP) program is seeking a full-time experienced SCHISM modeler to continue development of SCHISM models for the Columbia River Basin (river, estuary and coastal ocean) and for the Pacific Ocean Basin. This position will work collaboratively with fish scientists and managers to integrate numerical hydrodynamic modeling into conservation and management programs for critical fish species and stocks in the Columbia River, focusing on Upper Columbia summer and fall chinook and Snake River fall chinook, but including other salmonid species, lamprey, and sturgeon. Work may include incorporating high resolution wetland modeling, water control structures, and aquatic vegetation modeling into the existing CMOP SCHISM model and continuing development of individual based modeling of juvenile salmon. This position may also participate in or lead production of peer reviewed articles, technical reports, and grant proposals.

Position Details

  • Department: Watershed Department
  • Classification: Regular, Full-time, Non-Exempt
  • Salary/Wage Range: $75,799- $80,854
  • Location: Portland, Oregon

Essential Job Functions

Specific duties of this position include, but are not limited to:

  • Manage and develop SCHISM models, analyze data, and prepare reports, publications and oral presentations as needed.
  • Operate and advance existing hydrodynamic ocean models, such as the CMOP Virtual Columbia River SCHISM model, through appropriate programming.
  • Provide numerical modeling, analyses, and assessments to support CRITFC ecological objectives for the protection and recovery of Upper Columbia summer and fall chinook salmon and Snake River fall chinook salmon, other salmonid species, and lamprey and sturgeon.
  • Determine appropriate forcings (atmospheric, river discharge, river temperature) representing climate change and hydro-power management and use them as model inputs to predict changes in estuary and ocean conditions and resulting changes in salmon habitat.
  • Conduct modeling using appropriate scientific methods, in collaboration with other regional entities, to estimate changes from improved management of mainstem Columbia River operations to benefit tribal trust resources.

Job Requirements/Qualifications

  • M.S. degree in oceanography, coastal, ocean, environmental, and civil engineering, or a closely related field.
  • At least two years of direct work experience with numerical ocean modeling, using unstructured mesh models such as SCHISM, FVCOM, or ADCIRC, including experience with simulation management and analysis. A Ph.D. may substitute for some work experience.
  • At least two years of direct work experience working with Fortran and with Python, MATLAB, Linux shell script, or R. A Ph.D. may substitute for some work experience.
  • Be fully vaccinated for COVID-19 prior to the first day of employment.
