Acoustics

Notes from the field: guest post from Laura Bogaard

September 25, 2016

It was another beautiful day in the North Island neighborhood and Team Dolphin was all aboard our trusty research vessel, Wishart. We were cruising up Tribune Channel in search of our study animal, the Pacific white-sided dolphin (Lagenorhynchus obliquidens). The water was a magnificent pale blue—a reflection of the late-summer sky, and an indicator that this channel […]

Quiet(er) Marine Protected Areas

September 25, 2015

    Sound is as important to marine mammals as vision is to us.  Our new research, published open access in Marine Pollution Bulletin, has mapped areas that are important to 10 marine mammal species in BC, and overlaid those maps with maps of chronic ocean noise from shipping.  Most studies of this kind focus on […]

Co-founder wins prestigious Pew Fellowship to protect whales

February 24, 2015

We’ve been making a lot of noise about ocean noise for years.  Today, the Pew Charitable Trusts’ Marine Fellows Program announced that they’re listening.  Our co-founder, Dr Rob Williams, won a 3-year Pew Fellowship in Marine Conservation. He will use the award to expand his studies of impacts of ocean noise on whale, fish, and the interactions […]

It’s a fish-eat-fish world: does noise affect them?

February 17, 2015

We’re so grateful for this week’s special guest post from Inge van der Knaap, a Erasmus Mundus Master’s student in Marine Biodiversity and Conservation. Inge and her assistant, Sofya Reger, recently completed a beautiful experiment on noise and fish in collaboration with Salmon Coast Field Station.  Inge produced a great video introducing people to her study. […]

SHIPS PASS IN THE NIGHT

March 03, 2014

  Killer whales depend on a quiet ocean to navigate, find food and choose mates.  Much of our work with acousticians at Cornell involves estimating how much acoustic habitat whales are losing from chronic, rising levels of noise.  Here’s a simple animation that describes that work. In addition to masking the whales’ calls, animals can […]

A WEEK IN THE LIFE OF HARO STRAIT AND DOUGLAS CHANNEL

November 12, 2013

We recently published a paper reporting ocean noise levels in important whale habitats along the BC coast.  At the same time, we released an animation that outlined the key concepts.  Our research showed that the most important habitats for killer whales were the noisiest; important habitats for humpback whales were comparatively quiet. We thought you […]

Secret to a Sound Ocean

October 23, 2013

[vsw id=”77623625″ source=”vimeo” width=”425″ height=”344″ autoplay=”no”] Sound is as important to whales as vision is to humans. Our scientific research (with Chris Clark and Dimitri Ponirakis at Cornell University’s Bioacoustics Research Program) is measuring how noisy or quiet important habitats are to fin, humpback and killer whales in British Columbia, Canada, and how we think […]

Happy Spring!

March 26, 2013

“In the spring, at the end of the day, you should smell like dirt.” ― Margaret Atwood, Bluebeard’s Egg It’s officially spring!  Cherry blossoms are a sure sign that spring has sprung in the Pacific Northwest.  But for Pacific white-sided dolphins, spring means herring.  Each spring, Pacific herring find their way to inlets and coastal areas to […]

National Monuments and Marine Protected Areas

March 25, 2013

Today, President Barack Obama designated five new national monuments, including Cattle Point on San Juan Island in Washington state. This is exciting news, not only because Cattle Point is beautiful and has historic  relevance, but because important feeding habitat of one of the most critically endangered marine mammal populations in the US is just off Cattle […]

Acoustic ecology of harbor and Dall’s porpoise in BC

March 11, 2013

We are fascinated by porpoise.  We’ve published abundance estimates for harbor and Dall’s porpoise in the continental shelf waters of BC and then reanalyzed the data to produce pretty maps of harbor and Dall’s porpoise distribution. Our colleague Anna Hall has spent years studying these neat critters and is helping to identify how these two ecologically similar […]
