Since the public had an opportunity to comment on the Navys DEIS, did the public have an opportunity to comment on the Navys requested LOA to harass marine mammals?
Yes, the public had an opportunity to provide written comments about the Navy’s LOA request to the NMFS. Letters had to be postmarked no later than November 22, 1999 and sent to: Donna Weiting, Chief, Marine Mammal Conservation Division, Office of Protected Resources, National Marine Fisheries Service. What is the decibel level the Navy has asked permission to use in their LOA request to NMFS? The NMFS announcement of the Navy’s LOA request states that a 180 dB sound field will extend 2 kilometers from the ship. This means that the source level from the ship will be 246 dB. What is the difference in impact on marine life when LFAS is used at 203 dB which was the highest level in the Hawaii tests as compared to 246 dB which is the level the Navy intends to use the system at in normal operations? As you can imagine 246 does not equal 203. Because the decibel scale is logarithmic, higher dB values reflect much higher sound pressure levels. Therefore, a decibel level of 246 represents 20,0
