DESCRIPTION:Abstract: With increased human exploration and exploitation of 
 the seas\, our oceans have become noisier than ever\, driven by an increas
 e in commercial ships by more than 50% (in terms of deadweight). In Canada
 \, recent demands have led to a 20% increase in commercial shipping traffi
 c and the development of new seaport infrastructures to accommodate larger
  commercial vessels. With broadband noise in the 50Hz-10kHz range and sour
 ce levels of 150-180 dB\, there is a clear need to further study the envir
 onmental impact of such noise generation. The effects of underwater radiat
 ed noise (URN) on various components of the marine ecosystem\, from mussel
 s to marine mammals\, have been extensively studied in different disciplin
 es. Responses to noise vary between: (I) audibility\, (II) behavioral resp
 onses and stress reflected in altered vocalizations\, (III) masking of sou
 nds necessary for communication\, localization\, and foraging\, (IV) physi
 ological auditory threshold shifts\, and (V) physical damage (injury) to t
 he auditory system. Due to these effects\, ship noise is considered a sour
 ce of environmental pollution and should be monitored regularly through sh
 ip noise measurements. In this presentation we will discuss the impact of 
 increasing shipping activities on the health of marine biofauna. We will l
 earn what regulatory measures are currently being proposed to mitigate noi
 se pollution at global\, regional and local levels. We will also present t
 he activities of our laboratory to measure\, detect and assess the impact 
 of ship noise. Finally\, we will present a unique\, open-access dataset fo
 r URN from small ships and make the surprising observation that the noise 
 from small ships is comparable to that from large ships.\n\nSpeaker(s): Ro
