Several independent research projects that are listening to fish and whales in waters along the coast from New Jersey to Maine have joined together as the NorthEast Passive Acoustic sensing Network (NEPAN). This map shows the location of the various research programs that will be taking place through 2017:
The NEPAN website offers a good overview of the aims of each of these projects. Of particular interest is a real-time buoy deployed near a Coast Guard gunnery range off Rhode Island, which will help the Coast Guard to avoid initiating live-explosive exercises when any of the few remaining critically endangered North Atlantic right whales are in the area. The array of long-term recorders along the edge of the continental shelf will also provide some key new information on seasonal presence of many whale species, as well as helping clarify how far offshore they tend to be during migration (again, especially crucial information for the right whales).
