Mesoscale eddies transport deep-sea sediments
Mesoscale eddies, which contribute to long-distance water mass transport and biogeochemical budget in the upper ocean, have recently been taken into assessment of the deep-sea hydrodynamic variability. However, how such eddies influence sediment movement in the deepwater environment has not been explored. Here for the first time we observed deep-sea sediment transport processes driven by mesosc...
متن کاملUniversal structure of mesoscale eddies in the ocean
[1] Mesoscale eddies dominate oceanic kinetic energy at sub-inertial frequencies. Their three-dimensional structure has, however, remained obscure, hindering better understanding of eddy dynamics. Here by applying the composite analysis of satellite altimetry and Argo float data to the globe, we show that despite remarkable regional differences in amplitude, extent and polarity, etc., mesoscale...
متن کاملAn avenue of eddies: Quantifying the biophysical properties of mesoscale eddies in the Tasman Sea
[1] The Tasman Sea is unique characterised by a strong seasonal western boundary current that breaks down into a complicated field of mesoscale eddies almost immediately after separating from the coast. Through a 16-year analysis of Tasman Sea eddies, we identify a region along the southeast Australian coast which we name ‘Eddy Avenue’ where eddies have higher sea level anomalies, faster rotati...
متن کاملDeep mesoscale eddies in the Canada Basin, Arctic Ocean
[1] Numerous eddies have been identified in a seven year time series of mooring observations in the Canada Basin, Arctic Ocean. We focus on a series of deep eddies centered at 1200 m depth, and occupying up to 1500 m of the water column. The deep eddies are found to be spatially localized, only ever being observed at one of four mooring sites of the Beaufort Gyre Observing System in the Canada ...
