Materials scientists and engineers develop, process, and test materials for hydropower components and technologies.

A remote sensing and geographic information systems (GIS) specialist is responsible for building and maintaining GIS databases. They use software programs to collect, analyze, model, and present geographic data.

Quality assurance engineers run tests on hydropower electrical, mechanical, or software components to make sure the components work as designed, meet safety regulations, and satisfy client expectations.

Captains command the vessel and crew. Mates report to captains and higher-ranking mates and supervise crew members to operate the vessel effectively. Pilots work with captains and mates to steer vessels into and out of harbors.

Naval architects and marine engineers support the design, building, and operation of boats, ships, floating and fixed ocean platforms, and mooring systems.

Hydrologists analyze hydrologic and geologic field data, water-level data, or instrumentation data to estimate risks and water resource availability and support engineering design and construction of hydropower infrastructure.

Environmental engineers use the principles of engineering, oceanography, marine biology, and chemistry to develop solutions that mitigate or prevent environmental problems related to the marine energy industry.

Metal and plastic machine workers set up and/or operate equipment to cut, shape, and form precision metal and plastic parts.

Assemblers and fabricators assemble both finished products and the parts that go into them. They use tools, machines, and their hands to make generators, computers, electronic devices, turbines, and other parts.

Physical oceanographers study ocean physics, such as the movement of seawater and sediment, interactions between oceans and coastlines, interactions between the ocean and the atmosphere, and many other ocean processes.
