Gateways and climate: The Drake Passage opening
(Istituto Nazionale di Oceanografia e di Geofisica, 2010-06)
The Oligocene opening of the Drake Passage between the southern tip of South America and the Antarctic Peninsula, and the subsequent evolution of the Scotia plate, have definitively separated Antarctica from the other ...
Dinoflagellate cyst distribution during the Middle Eocene in the Drake Passage area: paleoceanographic implicationsDistribución de quistes de dinoflagelados durante el Eoceno Medio en el área del Pasaje de Drake: implicancias paleoceanográficas
(Asociacion Paleontologica Argentina, 2014-06)
The middle-late Eocene (45-36 Ma) dinoflagellate cyst distribution in high latitudes of the Southern Hemisphere has been explained by a surface ocean circulation pattern characterized by extensive subpolar gyres around ...
Baroclinic Transport Time Series of the Antarctic Circumpolar Current Measured in Drake Passage
(American Meteorological Society, 2014-07)
The first multiyear continuous time series of Antarctic Circumpolar Current (ACC) baroclinic transport through Drake Passage measured by moored observations is presented. From 2007 to 2011, 19 current- and pressure-recording ...
Detrital-zircon geochronology of the eastern Magallanes foreland basin: Implications for Eocene kinematics of the northern Scotia Arc and Drake Passage
(Elsevier Science, 2009-07)
U/Pb detrital-zircon geochronology of eleven sandstones collected from Cretaceous through Oligocene strata of the eastern Magallanes foreland basin of southernmost Argentina records a dramatic provenance shift near the end ...
Twenty-five years of Mercator ocean reanalysis GLORYS12 at Drake Passage: Velocity assessment and total volume transport
(Elsevier, 2019-12)
Velocities in Drake Passage from the 25-year GLORYS12 Mercator Ocean reanalysis were compared with satellite altimetry-derived surface velocities and independent in-situ velocity measurements from the DRAKE (2006–2009) and ...
Copepod distribution in surface waters of the drake passage using continuous plankton recorder and a Pump-Net onboard system
(Instituto Oceanográfico, 2012-07)
There is no single instrument that can sample quantitatively the complete spectrum of pelagic organisms, or even all the components of zooplankton. Mesh size is the main factor affecting species selectivity in the Continuous ...
Anatomy of the Antarctic Circumpolar Current volume transports through Drake Passage
(American Geophysical Union, 2016-04)
The 20 year (October 1992 to August 2013) observation-based volume transport time series of the Antarctic Circumpolar Current (ACC) through Drake Passage (DP) across the Jason altimeter track #104 is analyzed to better ...
