• Supporting boat-based fieldwork and equipment deployment, including assisting with field crew operations.
• Managing boating logistics such as equipment transport, maintenance planning, vessel readiness, and coordinating launch/recovery activities.
• Assisting with field scheduling, coordination, and communication with research staff, visiting researchers, and crafts personnel involved in boating operations.
• Helping ensure boating activities remain safe and efficient under changing field conditions, adhering to DOE and applicable regulatory requirements.
• Monitoring field conditions, identifying operational needs, and recommending improvements related to boating safety and efficiency.
• Keeping detailed records and writing reports related to field deployments, boating operations, and telemetry work.
• Supporting tagging activities or assisting with surgical implantation of transmitters in fish and ensuring safe boat-based transport and release schedules.
