Cascadia Research conducts long-term research on humpback and blue whales both along the West Coast of the United States as well as off Central America. Cascadia is also a principal organization conducting and coordinating the SPLASH humpback whale research effort in the entire North Pacific. 

PURPOSES OF THE RESEARCH

The objectives of our research include:

• Determine the abundance of humpback and blue whales off California.
• Determine trends in these populations.
• Identify critical feeding habitats that need protection, and
• monitor potential human-caused threats to large whale populations off California.
