Bermuda’s Tale of Two Time Series: Hydrostation S and BATS*
This paper describes the oceanic variability at Bermuda between 1989 and 1999, recorded in two over-lapping hydrographic time series. Station S and Bermuda Atlantic Time Series Study (BATS), which are 60 km apart, both show that a multidecadal trend of deep warming has reversed, likely as a result o...
