Ocean Animal Emergency: Premiering November 25 at 8pm ET/PT on PBS (check local listings). The world's oceans are in trouble. Warming seas and man-made pollutants are combining to unleash toxic algae blooms that are decimating whales, sea lions and other marine mammals. NOVA explores this crisis through the exploits of Dr. Frances Gulland, a San Francisco veterinarian who runs the equivalent of a West Coast ER for marine mammals.
