Eruption deduction.In the article "Hot, Hotter, Hot: Climate seesawed during dinosaur age" (SN: 10/7/06, p. 228), the explanation for the increased ocean-surface temperature seemed to focus solely on atmospheric effects. I wonder if variations in undersea volcanism volcanism or vulcanism Any of various processes and phenomena associated with the surface discharge of molten rock or hot water and steam, including volcanoes, geysers, and fumaroles. might have contributed to the sudden spike in Pacific Ocean surface temperatures during the Aptian epoch of the Cretaceous period Cretaceous period (krĭtā`shəs), third and last period of the Mesozoic era of geologic time (see Geologic Timescale, table), lasting from approximately 144 to 65 million years ago. . If so, then a moderately higher release of volcanic ash See under Ashes. See also: Ash might have contributed to the sudden drop in ocean-surface temperatures.
