Sound Budgeting Field Trial in Stellwagen Bank

April 11, 2008

Stellwagen Sanctuary Noise Monitoring to be Model for “Sound Budget” Research Worldwide – The hydrophone array deployed in Stellwagen Bank is far more than a ship-strike warning system; it is the first large field test of what many bioacousticians have been long calling for: a global network of monitoring systems that will dramatically increase our understanding of […]

More evidence of fish being affected by shipping, energy development noise

January 4, 2018

A couple of recent studies have added to the increasing evidence that anthropogenic ocean noise can have deleterious effects on fish. As the years go by, it’s becoming clear that it’s not just whales and dolphins that are struggling with human noise in the sea. A lab-based study of European sea bass found that recordings […]

Humpback bottom-feeding is (somewhat) affected by shipping noise

August 20, 2016

AEI lay summary of:  Blair HB, Merchant ND, Friedlaender AS, Wiley DN, Parks SE. 2016. Evidence for ship noise impacts on humpback whale foraging behaviour. Biol. Lett. 12: 20160005. http://dx.doi.org/10.1098/rsbl.2016.0005 A new study looks for the first time at the impact of human noise on an important type of humpback whale foraging activity, bottom-feeding on […]

Fantastic ocean noise presentation from Leila Hatch of NOAA

May 18, 2014

Earlier this month, Leila Hatch, one of NOAA’s leading experts on ocean acoustics and a long-time researcher in and around Stellwagen Bank National Marine Sanctuary, presented an hour-long talk on ocean noise.  It’s been archived on the Open Channels website, and is available for streaming and download on Vimeo.   It’s by far the best […]

New paper details the acoustic quality of critical whale habitats

November 27, 2013

AEI lay summary of:R. Williams, C.W. Clark, D. Ponirakis, and E. Ashe.  Acoustic quality of critical habitats for three threatened whale populations.  Animal Conservation (2013). Innovative research along the coast of British Columbia has quantified the degree to which shipping noise is reducing the distance at which whale vocalizations can be heard.  This is one […]

New paper quantifies shipping noise impact on whale communication space

August 16, 2012

The latest paper to be published by the research team that’s been studying noise levels in and around the Stellwagen Bank National Marine Sanctuary concludes that in the waters off Boston, increasing shipping noise has reduced the area over which whales can hear each other to about one-third of what it used to be. “We […]

Fish survey sounds reduce humpback songs 120 miles away?

January 22, 2012

AEI lay summary of the following paper:Risch D, Corkeron PJ, Ellison WT, Van Parijs SM (2012) Changes in Humpback Whale Song Occurrence in Response to an Acoustic Source 200 km Away. PLoS ONE 7(1): e29741. doi:10.1371/journal.pone.0029741Read or download online (free) An ongoing research project that monitors whale calls and shipping noise in Stellwagen Bank east […]

AEI annual report, Ocean Noise 2009 is now available

March 15, 2010

The Acoustic Ecology Institute has published Ocean Noise 2009, the fourth in its annual series of reports reviewing new research and regulatory developments in ocean noise. AEI’s annual recaps are widely anticipated and circulated among ocean noise scientists and regulators, as well as within NGO and journalist communities. The report can be viewed or downloaded […]

New maps track ships drowning out whale communication

February 23, 2010

Ongoing research in Stellwagen Bank National Marine Sanctuary is providing ever more compelling visualizations of shipping noise and the much quieter calls of whales in the area. Scientists from Woods Hole Oceanographic Institute, NMFS, and Cornell have deployed networks of sound recorders, which allow them to track individual whales and ships and see how their […]

Breakthrough technique measures how much ocean noise reduces whales’ communication area

January 6, 2010

I’ve just finished reading what must be the most exciting research paper I’ve seen this year, barely nudging out a similar paper addressing terrestrial noise impacts. A small group of researchers, with Chris Clark of Cornell as the lead author, took a giant step forward in addressing the impacts of ocean noise on the communication […]

MMS acoustic monitoring workshop includes AEI ocean noise report as key reading

November 9, 2009

Thanks to Brandon Southall’s blog on his new SEA-inc website, which is fast becoming one of the best places to stay abreast of key ocean acoustics research, I heard today the details of what’s planned at the upcoming Minerals Management Service three-day workshop on Acoustic Mitigation and Monitoring Systems for Marine Mammals.  The workshop website […]

Whale Protection Listening System Near Boston Shipping Lanes

April 7, 2008

Listening Buoys Deployed in Shipping Lanes Near Boston – Ten hydrohones installed in December in and near Stellwagen Bank National Marine Sanctuary are now active, monitoring the busy shipping lanes for whales. When a whale is heard, tanker captains are notified within a half hour, and required to slow down (which reduces noise) and post lookouts, […]
