Core top alkenone biomarker unsaturation estimates (Uk'37) of sea surface temperature and alkenone concentration (C37total), and World Ocean Atlas estimates of 1955-2010 sea surface temperature (Boyer et al., 2018; Locarnini et al., 2019), Aqua MODIS estimates of 2003-2007 surface chlorophyll (NASA Goddard Space Flight Center, 2022 , doi:10.5067/AQUA/MODIS/L3B/CHL/2022), and modeled coccolithophore productivity (Losa et al., 2017, doi:10.3389/fmars.2017.00203) were obtained and compared for the eastern equatorial Pacific Ocean. Newly acquired alkenone biomarker data from Brown University supplements data from other sources (Bova, 2017 (doi:10.7301/Z0P26WKM); Conte et al., 2006 (doi:10.1029/2005GC001054); Dubois et al., 2009 ( doi:10.1029/2009PA001781); Horikawa et al., 2006 (doi:10.1029/2006GL025948); Kienast et al., 2012 (doi:10.1029/2011PA002254); Koutavas & Sachs, 2008 (doi:10.1029/2008PA001593); Liu & Herbert, 2004 (doi:10.1038/nature02338); Prahl et al., 2006 (doi:10.1016/j.gca.2005.08.02)). Core top and satellite-derived estimates of sea surface temperature and productivity were compared to assess the applicability of alkenone palaeothermometry and paleoproductivity reconstruction to the eastern equatorial Pacific.
