California Channel Islands Acoustic Receiver Array

From 2000 to 2005, PIER maintained a large acoustic receiver array encompassing five of the Channel Islands and three points along the mainland (Point Vicente, Point Dume, and Point Conception).  The objectives of the array were to assess the movements of key species (i.e., giant seabass, California sheephead, white seabass, kelp bass) in and around the Islands.   As seen in the map below, each yellow circle represents the range of one acoustic receiver (VR2). These receivers, located in the center of the yellow circle, have been determined to have an average detection range of 500 meters. These receivers are designed to pick up the acoustic signal emitted by transmitters that have been surgically implanted in select species of fish.  During the project duration, the PIER researchers implanted over 200 acoustic tags in four species of California coastal fishes.
