Net Zero Expeditions

Swim with mako sharks and encounter blue whales in Southern California's offshore waters alongside a crew of scientists and filmmakers who make every expedition as educational as it is unforgettable.

Departing from Hyatt Marina Mission Bay in San Diego, Net Zero Expeditions offers a range of personalized ocean experiences including family-friendly whale watching, blue whale expeditions, shark diving, ocean safaris, and citizen science research charters. Trips are led by experienced nature filmmakers and scientists committed to responsible wildlife encounters, and the company also provides film production support. Guest reviews describe swimming with mako sharks and mola mola in the offshore waters of Southern California. Founded around marine conservation and sustainability, the company tracks, limits, and offsets the carbon footprint of every expedition. Alongside its charters, Net Zero Expeditions runs several active programs: Pelagic Shark Research, the Sea to Soil blue carbon project, a Balloon Patrol marine debris recovery effort carried out on every offshore trip, and Open Waters, which provides free ocean access for guests from underserved communities. Every trip is built around the conviction that meaningful encounters with the ocean inspire people to protect what they experience. Whether joining a wildlife charter or contributing to citizen science research, guests participate in an operation that blends adventure with conservation-driven exploration across Southern California's offshore waters.
