Age datums, and abundance of Discoaster brouweri and Coccolithus pelagicus in ODP Site 180-1115 sediments
The relative abundance of warm-water Discoaster brouweri vs. cool-water Coccolithus pelagicus provides a useful proxy for interpreting Pliocene surface water temperature trends at Ocean Drilling Program Site 1115 (Solomon Sea). Surface waters were mostly warm during the early Pliocene with a slightl...
