Deposition of these fire particulates ( 19 ) would have been assisted by the 500 mm of rainfall received by the Men- tawai region during the 1997 wildfires and by atmospheric subsidence over the cold SST anomaly ( 6 ). Weakening and reversal of the monsoon and equatorial winds ( 7 ) in December 1997 also would have acted to further concen- trate nutrients and plankton into the Mentawai region from the upwelling plume offshore. Approximately 1.1 10 4 metric tons of Fe were released from the Sumatran wild- fires during 1997 ( 35 , 39 ), and exposure to sunlight and acid conditions during atmos- pheric transport in the smoke plume ( 36 ) would have allowed up to 90% of the Fe to exist as bioavailable Fe(II) ( 40 ). Only 0.2 to 0.8% of the Fe released from the Sumat- ran wildfires was required as bioavailable Fe(II) in the Mentawai region to meet the total Fe requirements of the 1997 red tide (Table 1) ( 13 , 41 ). Although these calcula- tions are estimates, it is clear that the 1997...
