Predicting multi-year North Atlantic Ocean variability
24 We assess the skill of retrospective multi-year forecasts of North Atlantic ocean 25 characteristics obtained with ocean-atmosphere-sea ice models that are initialized with 26 estimates from the observed ocean state. We show that these multi-model forecasts can 27 skilfully predict surface and subsurface ocean variability with lead times of 2 to 9 years. We 28 focus on assessment of forecast...
متن کاملNitrous oxide in the North Atlantic Ocean
In order to get a comprehensive picture of the distribution of nitrous oxide (N2O) in the North Atlantic Ocean, measurements of dissolved nitrous oxide were made during three cruises in the tropical, subtropical and coldtemperate North Atlantic Ocean in October/November 2002, March/April 2004, and May 2002, respectively. To account for the history of atmospheric N2O, we suggest a new depthdepen...
متن کاملNorth Atlantic surface-ocean control of Pleistocene deep-ocean circulation
Deep basins of the North Atlantic were occupied by a cold 13 C-depleted (nutrient-rich) water mass during glaciations, and a warmer 13C-enriched (nutrient-poor) water mass (modern NADW) during interglaciations. This mode of deep-water variability is related directly to migration of the North Atlantic Polar Front. Down-core stable isotope records from the Atlantic and Antarctic suggest that 13C ...
متن کاملOpen ocean dead zones in the tropical North Atlantic Ocean
Here we present first observations, from instrumentation installed on moorings and a float, of unexpectedly low (< 2 μmolkg) oxygen environments in the open waters of the tropical North Atlantic, a region where oxygen concentration does normally not fall much below 40 μmolkg. The low-oxygen zones are created at shallow depth, just below the mixed layer, in the euphotic zone of cyclonic eddies a...
متن کاملPolar vortex controls coupling of North Atlantic Ocean and atmosphere
[1] The structure of the North Atlantic leading atmospheric winter variability mode strongly depends on the state of the polar stratospheric vortex. If the polar vortex is strong, one teleconnection pattern emerges in the upper troposphere, while two mostly independent ones appear when the vortex is weak. The anomaly patterns associated with the different polarities of these modes show strong d...
