Large pelagic fishes such as blue sharks and swordfish                          although "cold blooded," appear to use heat acquired at the                     surface to remain warmer than the water at depth for many                       hours.  Swordfish swim near the warm surface to feed at                         night, but move deep into cold water during the day.  They                      appear to manipulate their body temperature by a thermal                        hysteresis in the muscle which cools slowly in deep cold                        waters, but rewarms rapidly upon return to warm surface                         waters.  Blue sharks, which swim up and down hundreds of                        meters in continuous oscillations, may be obtaining the same                    thermal advantage.  However, their continuous oscillations                      may be necessary because they are less effective in managing                    temperature than swordfish.  Dr. Carey, who has pioneered                       research on this topic, will continue his investigations into                   the process of behavioral thermoregulation in these fish.  He                   will combine telemetered information with shipboard                             measurements of water temperature vs. depth, light and                          echosounder records to investigate the factors the fish                         respond to.
