31. These anomalous easterlies induce more equatorial upwelling and raise the thermocline in the east, amplifying the initial cooling by the southerlies. 32. The continual diffuse upwelling of deep water maintains the existence of the permanent thermocline found everywhere at low and mid-latitudes. 33. If this rise were to stop, downward movement of heat would cause the thermocline to descend and would reduce its steepness. 34. Galapagos fur seal population is drastically affected by El Nino, a period accompanied by high water temperatures and a deepening thermocline . 35. Finally, the turbulent entrainment of colder thermocline waters caused by wind stirring also results in the cooling of the surface waters. 36. During the summer, a 25 cm deep water layer reaches temperatures above 25 �C . ( something of a thermocline ). 37. Below the thermocline the water is normally anoxic and from November to April the fish are found no deeper than 20 m. 38. Alt = Diagram of location of ship, thermocline , towed pinger locater at end of tow cable, and blackbox pinger. 39. Later in the summer, trout like to stay in cold water below the second thermocline , which is typically 50 70 feet. 40. Rather than maintaining a simple depth, the planesman must now keep the boat beneath a thermocline in order to hide from sonar.
