Orca Sound Participation Journal

  • Participation journal:
    • The training for this project was minimal yet fun and engaging. The participant is instructed to listen to several audio clips of different sounds that occur in the Salish Sea. Many of the sounds are anthopogenic like noises from speed boats, fishing vesicles, military SONAR, aircraft, and construction. But there are also a lot of natural sounds made by the inhabitants of the Salish sea like the harbor seal, sea gulls, gray whales, humpback whales, orcas, harbor porpoise, and California sea lions just to name a few. The participant is instructed to listen to all the different kinds of sound they might here and is then told to report any suspected identifications of orca sound to the researchers. I began listening to the natural sounds first because that is what I was most interested in hearing. Natural sounds we somewhat quieter and subtler than what I thought they would be so I turn the volume up on my headphones to get a better listen. I then switched to listening to human made sounds. I'm not sure if the researchers deliberately made these recordings louder than the natural ones but I actually hurt my ears a bit when I first played one of them. The pile drivers used in harbor construction and the military sonar were especially loud. 
    • The most interesting aspect of this project was the training. Being able to hear all the different sounds, natural and otherwise, that occur in our oceans was truly enlightening. Sitting and listening to the live audio feeds gives you time to reflect on how massive the ocean is and how massive a task it must be to communicate in in. Listening to harbor and shipping channel activities also gives you an idea of how far Man's reach has really gone. We have explored only a faction of our oceans yet our activities have polluted much of it whether it's an oil spill or noise pollution. Although I wasn't able to hear any orcas, I mostly just heard shipping vessels and ferries, I still enjoyed the experience and was able to appreciate the evolution of these creatures to their environment.
    •  I mostly listened to the audio feeds on the weekends Oct 28 from 5-6pm (training), Nov 3th from 8-9:30pm, and Nov 10th from 4-5pm.
  •  I think this project would be a cool thing to do every once in awhile, mainly when there is more natural activity in the Salish Sea around summer. This is definitely a project that I would encourage my friends to do if only to listen to the recordings of animals.

OrcaSound Public Outreach

Public outreach: My overall experience with this project is positive. It only took a quick google search and then some playing around with search filters to find an interesting citizen science project. I'm not exactly sure if this project is actively advertised but it is easily searchable. One thing that I would change about the project is making sure the audio training files are offered in several formats so everyone can participate regardless of their computer software specifications. Also, making the training mandatory would increase the barrier of entry but would also make sure participants aren't misinterpreting sounds. I think the educational aspect of this project is the strongest piece of it. Computer software can mostly do a better job at picking up natural sounds than humans can so long as the sounds are similar to ones recorded before. Combine that with the fact that you don't really have to pay a computer program and humans quickly become obsolete. However, t...

An Introduction to OrcaSound

Your blog posts will have multiple components over the course of the semester: O rcaSound Citizen Science Project: This project exists to monitor the habitat of the endangered Northwest Pacific orca by detecting and identifying the sounds of orcas and any dangerous noises. OrcaSound primarily uses computer software to distinguish natural from anthropogenic sounds; however, Human ears can do a better job of detecting unusual or new sounds. Therefore OrcaSound maintains live audio feed from its 5 hydrophones and also publishes recordings or various sounds and distinct orca calls.  OrcaSound is run by a broad coalition of organizations including Beam Reach, Colorado College Physics and Environmental Science Dept, The Orca Network, Port Townsend Marine Science Center, the Orca Behavior Institute, Cetacean Research Technology, and many others. Primarily, OrcaSound is funded by the National Oceanic and Atmospheric Administration.  The citizen scientists are primarily ...

OrcaSound Project Design

Project design: Once an unusual, man made, or natural sound is identified, the participant is instructed to make an entry on  a community spreadsheet and send an email to an inbox maintained by the researchers. From there, the data is aggregated and used to study when the southern resident orcas and other species are active in the Salish Sea. researchers can then make recommendations to policy makers about noise pollution levels and activity levels of the aquatic wildlife.  Reviewing data could be made easier by creating some sort of tool or app that allows the listener to flag the exact time within the audio recording that they heard the sound. The way that the project is set up now, participants can only describe what they heard and only through running a separate software program can they provide an audio clip of what they heard. This limits the quality of data being collected. I think the partnerships that OrcaSound have forged in order to maintain the hydrophones are ...
