The maximum of the anomaly between 10.89 and 11.00 m below seafloor correlates with the maximum abundance of microtektites. Iridium abundances, which show the most significant anomaly, reach 0.16 ppb, which is evidence for an extraterrestrial component. 90.3612 90.3612 5.384 5.384 90.3612 5.384 1988-06-15T04:40:00
