Welcome to Cetos Research

Cetos Research Organization is a non-profit organization that conducts marine wildlife research and supports educational efforts in conservation and wildlife sciences in the marine environment as well as other habitats. Through our findings, we work to enhance and augment conservation and management of living marine and wildlife resources.


Our Research Projects

Cetos's scientific research efforts are currently focused in the Pacific waters of Hawai'i, as well as the Gulf of Maine, Alaska, Washington, California, and elsewhere throughout the world, including studies of the critically endangered vaquita in Mexico.

Humpback Behavior Project

Our longest running project on the behavioral ecology of Hawaiian humpback whales.

Offshore acoustic and visual surveys

Deepwater surveys looking at vocalizations of different species using different techniques.

Vaquita Project

Behavior, photo-identification, and population studies of this critically endangered porpoise only found in Mexico.

What is Cetos

Cetos Research Organization is a non-profit organization with a focus on studying endangered marine species and other wildlife species about which little is known. We identify and assess anthropogenic impacts especially on marine wildlife, and when appropriate, propose solutions to minimize potential disturbances. We have offices on the east coast (Cetos Atlantic), California (Cetos Pacific), and Hawai'i. All our personnel contribute on our various projects throughout the US and internationally.

Monitoring Surveys and Mitigation

Cetos Research LLC is a business arm of our collective with staff who bring the capability to lead and perform monitoring surveys for marine mammals and sea turtles, the experience to address mitigation work, and the background to produce environmental documentation such as EISs, EAs, BAs, etc. Our monitoring surveys can be performed from vessels and/or aerial based platforms for at-sea observations. Cetos LLC can supply a variety of reports and products, including but not limited to survey designs, mitigation plans, environmental reports, and more. These surveys are effective both as strategies to collect “baseline” data in waters where future projects will occur, or for real-time assessment of any effects of active offshore projects. Our reports cover issues related to ESA, MMPA, and NEPA.
