Foraging in the Abyss: Killer Whales and Submarine Canyons
Some killer whales have specialized in navigating submarine canyons to hunt marine mammals that exploit deep-sea species. How do they do it?
How do marine mammals make decisions about diving?
PhD candidate Rhea Storlund decided to take an unconventional approach to understand how marine mammals dive by asking human breath-hold divers about the decisions they make.
Grey Whales — the other Pacific Northwest resident whale
Grey whales face many threats ranging from entanglements and ship strikes, to loss of habitat and reduced prey availability. Researchers are collecting data this summer needed to quantify and mitigate these threats.

Decoding the secret lives of killer whales one micro-second at a time
Long gone are the days when a biologist could analyze a set of behavioural data by hand. Advancements in technology have put an end to that. Fortunately, teams of statisticians are coming to the rescue.
Grey Whale Watching in Baja California Sur, Mexico
It’s that time of year again, when people and grey whales head to the lagoons of Baja, Mexico for the annual winter event.
Long-term studies quantify the prey requirements of pinnipeds, and help predict the effects of nutritional stress.
Two new studies answer the question: “How much fish does a seal need?” One of the most common threats to marine mammal populations is reduced food supply, either due to the effects of climate change or human fishing pressure.
How big is that whale?
New data from stranded whales is yielding better estimates of body sizes needed to determine drug dosages, and assess the health and food requirements of whales.
You can’t beat a healthy heart
