New Paper: Using acoustics to learn about harbour porpoise behaviour in tidal environments

Last week our colleagues at SMRU and PAMGuard published a paper on an approach they developed to successfully find and track harbour porpoise in tidally active areas. Their paper entitled Passive acoustic methods for fine-scale tracking of harbour porpoise in tidal rapids was published in the Journal of the Acoustical Society of America.

NOAA Releases Draft Ocean Noise Strategy Roadmap

 

This month we were really excited to see the US National Oceanic and Atmospheric Administration (NOAA) release their draft Ocean Noise Strategy Roadmap for public comment. This is the first coordinated initiative by the US regulator to address issues of man-made noise in the oceans. And, SMRU Consulting is already collaborating on this novel effort as NOAA are currently assessing our (interim) Population Consequences of Disturbance (PCOD) framework to assess impacts of noise on Cook Inlet Beluga (more on this later!).

Check out the Ocean Noise Strategy efforts and the recently released Roadmap here. Public comments on the draft Roadmap are welcomed by NOAA until July 1, 2016.

Wave gliders: game changing technology for monitoring marine mammals

East Carolina University’s Blackbeard wave glider has survived its first at-sea trials this week and has been successfully deployed off the North Carolina coast. The Blackbeard wave glider is manufactured by Liquid Robotics and contains a St Andrews Instrumentation Decimus® system to detect marine mammals.

Opportunity sites are ocean optimism sites

Scientists have identified ‘opportunity sites’ for protecting marine mammals from ocean noise in the coastal waters of British Columbia. The team from SMRU, Oceans Initiative, Curtin University, and Cornell University has highlighted the importance of protecting habitats that experience low levels of shipping noise.

Sounds of the Sea: How to Listen to the World’s Largest Database of Marine Mammal Sounds

Did you know that bearded seals sound like spaceships? That blue whales can communicate across ocean basins? That humpback whales sing songs? And that dolphins make sounds through their blowholes?

Most terrestrial animals rely heavily on their senses of sight and smell to communicate. In water, these senses are limited because light is readily absorbed and scents do not diffuse in water as rapidly as in air. Marine mammals have therefore evolved to use sound as their primary means of communication.

The Secret Lives of Marine Mammals

This week, SMRU Consulting North America is participating in a workshop on biomonitoring (using animals to explore isolated habitats) and biologging (tracking animals to describe their behaviour).  The workshop, ‘Building a Bio-analytical Theory for the Analysis of Marine Mammal Movements’ is being held by the Peter Wall Institute for Advanced Studies and is sponsored by the University of British Columbia, the Pacific Institute for Mathematical Sciences, and the Canadian Statistical Sciences Institute.
