Mission and Work


The MARINE MAMMAL CENTER advances global ocean conservation through marine mammal rescue and rehabilitation, scientific research, and education. The center's work is guided and inspired by a shared vision of a healthy ocean for marine mammals and humans alike.

Rescue and Rehabilitation

$5.2m annual program spend • The MARINE MAMMAL CENTER rescues and rehabilitates sick and injured marine mammals at its state-of-the-art veterinary facilities by engaging a dedicated workforce and a supportive community. Since 1975, the center has responded to more than 24,000 marine mammals, including sea lions, elephant seals, harbor seals, fur seals, sea otters, and more. In an effort to save hawaiian monk seals from extinction, the center opened the first-ever rehabilitation facility devoted to this endangered species in 2014, and since then has rehabilitated nearly 2 percent of the total population, which is estimated at about 1,400 individuals. In 2018, the center treated more than 802 marine mammals in total, including a record number of elephant seals. The center's workforce includes more than 1,300 volunteers who recorded more than 152,000 volunteer hours served in 2018, an estimated workforce value of approximately $4.4 million.

Scientific Research

$1.6m annual program spend • The MARINE MAMMAL CENTER learns from the patients in its care and contributes to scientific understanding of the changing health of our ocean, taking action to address ocean threats and save endangered species. In 2018, scientists at the center contributed 13 research papers to peer-reviewed journals and hosted 113 visiting students and researchers from all over the world interested in learning from the center's world-class team of experts.


$2.5m annual program spend • The MARINE MAMMAL CENTER leads as a teaching hospital by training veterinary professionals locally and internationally, and inspiring future ocean stewards through innovative school and public education programs. In 2018, the center engaged more than 100,000 children and adults as visitors at the sausalito hospital as well as through outreach programs and community events in California and Hawaii.
