Ship noise extends to frequencies used by endangered killer whales

When an endangered orca is in hot pursuit of an endangered salmon, sending out clicks and listening for their echoes in the murky ocean near Seattle, does the noise from the nearby shipping lane interfere with them catching dinner? To find out, scientists measured underwater noise as ships passed their study site 3,000 times. This unprecedented characterization of ship noise will aid in the understanding of the potential effects on marine life, and help with possible mitigation strategies.

Mandatory Ship Reporting System for North Atlantic Right Whales

 The Coast Guard is helping to get the word out about the importance and effectiveness of speed limits and the responsible use of the safety exception as they relate to the North Atlantic Right Whale. Therefore,  some of the annual seasonal speed restrictions, in the mid-Atlantic areas, came into effect on November 1, 2015 and will remain in effect until April 30, 2016.“NOAA’s robust and practical enforcement strategy has yielded very positive results – particularly on approaches to pilot stations.” said Rear Adm. Paul Thomas, assistant commandant for prevention policy.“The safety exception is an important part of the process. We greatly value the input provided by professional mariners, who benefit from a reasonable enforcement approach that considers the challenges of ensuring safe navigation in confined waters.”Also,  the National Oceanic and Atmospheric Administration’s National Marine Fisheries Service (NMFS) is conducting a survey of its North Atlantic Right Whale Mandatory Ship Reporting (MSR system). The purpose of the survey is to evaluate and improve the MSR program.If you are a mariner operating or working on a vessel 300GT or greater on the east coast of the United States, or who has operated in this area in the past, NMFS is seeking your input on ...
