How does the Sound Fixing and Ranging (SOFAR) channel support our study of climate change?

W) The deep SOFAR channel is populated with organisms extremely sensitive to ocean temperature change

X) World War II submarines gathered rich and extensive data sets about the SOFAR channel that can be compared with current data

Y) Video monitoring of marine mammal mating behavior is useful because mating behavior in this region is impacted by temperature

Z) Speed of sound is temperature-dependent in the SOFAR channel
Z) SPEED OF SOUND IS TEMPERATURE-DEPENDENT IN THE SOFAR CHANNEL
