Core top alkenone sea surface temperature and productivity data compared to modern observations in the eastern equatorial Pacific

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.
