Unmanned Aerial Systems
The Cetacean Health and Life History Program continues to develop new tools for the assessment of marine mammals and contribute crucial data to our mandated research efforts. Our team works closely with colleagues in the Marine Mammal and Turtle Division to monitor the life history, condition and health of cetacean populations. Our data is essential to regular abundance estimates.

Evaluating Killer Whale Predation on Gray Whales
- Meet a One-Eyed, Six-Legged, Flying Whale Chaser:
Wayne Perryman and the Photogrammetry Program was featured at
The article highlights the lessons learned and the move forward to a less obtrusive method to spot marine mammals, with the use of an unmanned aerial system.
- Researchers deploy drones to spy on sperm whales:
Wayne Perryman was featured in the Pete Thomas Outdoors, action and adventure website as seen
The article highlights the goal of using an
unmanned aerial system to research large whales, such as the sperm whale. Unmanned aerial systems are non-invasive and can be flown closely to mammals without altering their behavior, unlike a normal aircraft or ship.
- CA Coastal Bottlenose Dolphin Health Assessment Research:
The Photogrammetry and Life History Program has initiated the development of a new marine mammal health assessment project. This is a collaborative effort with several institutions, bringing together a diversity of expertise. The first phase of fieldwork began in November 2008, and is focused on assessment of persistent organic pollutants (POPs), such as PCBs, DDTs, HCHs and PBDEs, in coastal bottlenose dolpins off San Diego County and around the Channel Islands.
Aerial Photos Give Perspective on Gray Whales:
Wayne Perryman and the Photogrammetry Program was featured in the San Diego Union Tribune as seen
on the UT San Diego website. The article highlights the goal of using aerial photogrammety to estimate reproductive and nutritive condition of
gray whales based on their size and shape.
Killer Whale predation on Gray whales: SWFSC scientist John Durban is featured in the BBC series "Ocean Giants" as seen
on the BBC One website. The video clip demonstrates killer whale tagging operations as part of an ongoing study to understand
killer whale predation on gray whales.
- Killer Whales soff La Jolla, CA
MMTD scientists encountered a pod of eight Killer Whales (Orcinus orca) off La Jolla on January 15, 2009. The pod included two adult males and two calves. The orcas chased a large school of Common Dolphin (Delphinus sp.) offshore.

- Snowball Fight! Scientist vs. Killer Whale:
Bob Pitman shares the story of his snowball fight with a Killer Whale in Antarctica. This amazing interaction took place during a field study with Wayne Perryman and Don LeRoi in 2007.
