    I know one of the scientists at the Ocean Centre in N. Saanich who is involved in this study. I'll try and contact him to see if he has any updated data or background info to share.

    You know what bugs me about this one?
    The US Navy has been listening and recording VERY carefully for decades!!! The Canadian Navy listens to some degree as well. Has the government really exhausted every avenue to gain some of this information from the Navy or our southern Neighbours? What a waste of resources to spend time and money on hardware to collect information that is almost certainly being recorded already.

    agreed, TC - except the Navy recordings are likely classified and unavailable due to "National security concerns" - or other such rubbish..

    Agreed. It’s just that to me, even if we dedicated two public servants for a whole year to negotiate and work on some sort of collaboration with the US and Canadian navies to sort out and separate the info they need from that which is “classified”, it would still cost a mere fraction of the 7.2 million they are now going to spend.
    At last week’s vessel slow down wrap up meeting (the trial run in Haro Strait is over) all of the parties involved agreed that lack of food is the major problem facing our resident Orcas. Yes we need to work on vessel noise (whale watching will no longer be lumped on the conservation side) perhaps by slowing things down, but for crying out loud we need to feed the whales by bringing Chinook salmon back! Everyone involved agrees!!!
    So now we’re going to spend another 7.2 million listenening to them?? What??!?! Why?
    What a waste. I’m sure 7.2 million wouldn’t go that far rehabilitating rivers and spawning grounds but it sure would help. Too bad fancy new electronics are so much sexier than muddy boots on the ground actually accomplishing something.

    Listening to the Deep Ocean
    https://www.pri.org/stories/2011-12-29/listening-deep-ocean
    "It's a region where we have naval operations," says Robert Winokur, a Navy oceanographer. "It's [also] a region where the Canadian Navy has naval operations."

    He says allowing the general public to listen to that part of the ocean poses a threat to national security because someone — he won't say who — might use that information to target Navy vessels.

    Listening station to study impact of ship noise on whales
    September 15, 2015 Vancouver, B.C.: The Vancouver Fraser Port Authority (VFPA), with support from the University of Victoria’s Ocean Networks Canada and JASCO Applied Sciences, has deployed a hydrophone listening station that will monitor underwater vessel noise in the Strait of Georgia. Underwater noise has been identified as a key threat to at-risk whales.

    Moore, K. A. (2016). Evidence-informed conservation policies: Mitigating vessel noise within gray whale (Eschrichtius robustus) foraging habitat in British Columbia, Canada [graduate project]. Halifax, NS: Dalhousie University.

    Abstract
    Anthropogenic noise is increasing within our oceans from growing human use. This rise in the ambient soundscape of the marine environment is increasing pressure on the life processes and health of marine animals. Cetaceans rely on the use sound for their life processes, and are thereby particularly susceptible to anthropogenic noise, like that from boats and other vessels.

    Whale watching vessels are directly exposing whales to their noise output. The current literature postulates that baleen whales are less susceptible to smaller vessels, like whale watching boats, as smaller boats emit high frequency sound, presumed out of the range of baleen whale low frequency communication. This interaction is analyzed within the foraging habitat of the eastern Pacific gray whales (Eschrichtius robustus) in Clayoquot Sound, British Columbia using passive acoustic monitoring. Noise disturbance from whale watching vessels is investigated using acoustics to analyze the contribution of vessel noise to the background sound levels of gray whale foraging habitat, and the differences in gray whale vocalizations in the presence of vessel noise.

    Evidence of acoustic disturbance is coupled with an analysis of the current policy regime and characterization of the Tofino whale watching fleet whale encounters to recommend future management and policy adoption to minimize cumulative impacts of vessel noise on gray whales. The enablers and barriers to evidence use within policy and management are identified to ease amendments to the current strategies for effective whale conservation in BC. This evidence-use approach supports strengthening acoustic protection of cetaceans, which assists in safeguarding the local tourism activities of whale watching.

    Not sure where you get the time or info, Agent?!

    Good on ya for finding such, and spending time on such.

    I have to admit though, I get turned off from reading threads when instead of individual opinions and knowledge sharing - it's frequently becoming you sharing your lit search and links of research all over the forum

    Great, another potential restriction coming from a knee jerk reaction based on next to zero evidence. How about more strategies to feed the damn things? Ships and boats in the Gulf of Georgia are nothing new. This was not a problem with abundant fish stocks.
