Jan-Feb 2027: Delta Discovery Voyage trips
Forms and Information
Join the Marine Science Institute for a 3.5-hour expedition on the Sacramento-San Joaquin Delta aboard the 90-foot research vessel, the R.V. Robert G. Brownlee. Discover the life in the delta and how we are connected to our watershed. Students rotate through 4 stations using scientific methods and research equipment to examine different types of life and learn where their water comes from.
The Discovery Voyage is limited to the participating class, teacher and authorized chaperones permitted to attend the field trip. This program is in part sponsored by local water agencies.
