Seasonal to interannual upper-ocean variability in the Drake Passage
Year-round monitoring of the upper-ocean temperature variability in Drake Passage has been undertakensince September 1996 through repeat expendablebathythermograph(XBT) surveys. The closely spaced measurements (6–15 km apart) provide the rst multi-year time series for examining seasonal to interannual variability in this Southern Ocean choke point. While the temperature sections reveal the se...
متن کاملSurface flux and ocean heat transport convergence contributions to seasonal and interannual variations of ocean heat content
We present an observation-based heat budget analysis for seasonal and interannual variations of ocean heat content (H) in the mixed layer (Hmld) and full-depth ocean (Htot). Surface heat flux and ocean heat content estimates are combined using a novel Kalman smoother-based method. Regional contributions from ocean heat transport convergences are inferred as a residual and the dominant drivers o...
متن کاملThe Seasonal and Interannual Variability
The Labrador Sea, as one of a few places of deep water formation, plays an important role in the Meridional Overturning Circulation. While the interior of the Labrador Sea, where the deepest convection takes place, is known to experience variability on time scales ranging from days to decades, little is known about the variability of the other components of the Labrador Sea circulation the boun...
متن کاملAnalysis of seasonal and interannual variability in transpacific transport
[1] The purpose of our analysis is both to evaluate the meteorological component of the seasonal and interannual variability of transpacific transport and to identify meteorological features that can be used to estimate transpacific transport. To accomplish this goal, we simulate the transport of nine continental tracers with uniform emissions and two-week lifetimes using the global Model of Oz...
متن کاملSeasonal variability of upper ocean heat content in Drake Passage
[1] Mixed-layer depth (MLD) is often used in a mixed-layer heat budget to relate air-sea exchange to changes in the near-surface ocean temperature. In this study, reanalysis heat flux products and profiles from a 15 year time series of high-resolution, near-repeat expendable bathythermograph/expendable conductivity-temperature-depth (XBT/XCTD) sampling in Drake Passage are used to examine the n...
