Tropical ocean‐atmosphere controls on inter‐annual climate variability in the Cretaceous Arctic
[1] The first annually resolved sedimentary record from the Cretaceous is used to develop time series of inter‐annual and decadal scale climate variability from the Arctic Ocean. Analysis of records spanning 1000 years reveals strong per-iodicities in the quasi‐biennial oscillation and El Niño ‐ Sou...
