Conference snapshot: Listening to the Salish Sea

Body: 

One of the hot topics at the Salish Sea Ecosystem Conference this week is the impact of shipping noise on marine mammals such as the region's endangered Southern Resident Killer Whales. As vessel traffic increases in the Salish Sea, so does chronic noise, which scientists say can alter whale behavior or even mask communication between species. Now scientists are saying that this may be an even bigger issue, affecting species across the board.

Conference coverage from Salish Sea Currents

Body: 

Watch for updates and stories from the 2016 Salish Sea Ecosystem Conference in Salish Sea Currents. We are sending ten science writers to Vancouver to cover key findings—from the fascinating to the decision-critical—emerging from more than 450 talks scheduled for this week's conference. These stories will be published throughout the year on the Encyclopedia of Puget Sound. If you want a sense of what is happening during the week, our writers and others will be posting to Twitter using the hashtag #SSEC16.
