  • [1] Secular trends in coastal upwelling proxies from a sediment record at 23°S encompassing 250 years reveal two distinct stages separated by a transition period between AD 1820 and 1878. Persistent interdecadal variability that roughly follows the Pacific Decadal Oscillation is accompanied by intensification of upwelling-favourable coastal winds and decreased coastal sea surface temperature since AD 1878. We propose that an increased land-sea thermal contrast along the arid coast of northern… CONTINUE READING
