Abstract | dc.description.abstract | We reconstructed a high‐resolution, alkenone‐based
sea surface temperature (SST) record spanning the last
ca. 150 years, from a sediment core retrieved within the
main upwelling zone off Peru. A conspicuous SST
decline is evidenced since the 1950s despite interdecadal
SST variability. Instrumental SST data and reanalysis of
ECMWF ERA 40 winds suggest that the recent coastal
cooling corresponds mainly to an intensification of
alongshore winds and associated increase of upwelling
in spring. Consistently, both proxy and instrumental data
evidence increased productivity in phase with the SST
cooling. Our data expand on previous reports on recent
SST cooling in other Eastern Boundary upwelling
systems and support scenarios that relate coastal
upwelling intensification to global warming. Yet,
further investigations are needed to assess the role of
different mechanisms and forcings (enhanced local
winds vs. spin‐up of the South Pacific High Pressure
cell). | es_CL |
