Interns in the Marine Biology Internship Program (MBIP) participate in research projects conducted by The River Project and its partners and are assigned to a variety of projects depending on their interests and skill level. Interns help catch and maintain the organisms housed in the 3,500-gallon flow-through aquarium system and learn a variety of skills including water quality testing, organism identification, behavioral observations, and other important lab and field skills. Interns will also participate in environmental education, teaching what they have learned. Interns plan and host a Wetlab Look-in centered on a Hudson River Estuary topic of their choice.

A more lab-based internship is offered to experienced undergraduate students with an interest in environmental science and water quality. They help with the Citizen’s Water Quality Testing Program and learn how to take water samples for bacterial assessment and learn lab techniques for bacterial culturing using the industry-standard kit and protocol from IDEXX. This program runs for 20 weeks from May to October. Interns must be available Thursdays and Fridays for sample processing and analysis.

Environmental Education Positions

The River Project also offers Environmental Education Internship positions students currently enrolled in college who are studying biology, ecology, or another relevant field. These interns assist the educators and staff on field trips and have an opportunity to run a topic station on their own. Topics can include, but are not limited to, water quality, microscopy, fish biology, estuary ecology, and research sampling.Interns must be available some weekday mornings to assist with TRP education programs. Those interested in Environmental Education positions should email a résumé/CV and cover letter to Director of Education Melissa Rex at

General Requirements


Interns at The River Project are required to be at least 16 years old and have an interest in environmental studies/science, marine biology, or other natural sciences. Interns must be able to dedicate at least 8 hours per week (Monday-Friday, 10am-6pm), preferably in 4+ hour blocks. As all the internship positions are very hands-on, applicants must be willing to get muddy, handle live aquatic organisms, and be comfortable around children. The internships are unpaid but can qualify for school credit, dependent on the credit-granting institution.

The MBIP has three cycles that follow school semesters:
Spring (March/April-May/June), Summer (May/June-August/September), and Fall (August/September - November).

The deadlines to apply for each cycle are as follows:

  • Spring Cycle: January 30th SPRING APPLICATIONS ARE CLOSED


  • Fall Cycle: TBD
