Published 2010-07-01“…A longer period of transgression towards the top of the succession may be related to a rise in sea-level or accelerated tectonic subsidence, whereas a major regression commencing at around 23.3 Ma probably coincides with the opening of the Drake Passage and the growth of the East Antarctic Ice Sheet.…”

Published 2005-12-01“…The most relevant differences in the associated circulation to volume extremes of the Regions I and whit respect to the Region II would be: 1) the displacement of the circulation systems towards higher latitudes, 2) the greater relevance of the middle latitude systems, 3) the smaller importance of the systems located on the Drake Passage and 4) the presence at 500 hPa of a smaller longitude stationary waves train that crosses the continent at subtropical latitudes coming from the central Pacific in NW-SE direction.…”

Air-Sea CO<sub>2</sub> fluxes in the Atlantic as measured during boreal spring and autumn
Published 2010-05-01“…The Southern Oceans sampled in the Drake Passage behave as an average uptake rate of −1.1 ± 0.9 mol m<sup>−2</sup> yr<sup>−1</sup> while the distal shelf of the Livingston Island acted as a slight source of CO<sub>2</sub> to the atmosphere.…”

The INALT family – a set of high-resolution nests for the Agulhas Current system within global NEMO ocean/sea-ice configurations
Published 2019-07-01“…Large-scale measures such as the Drake Passage transport and the strength of the Atlantic meridional overturning circulation are rather robust among the different configurations, indicating the important role of the hosts in providing a consistent embedment of the regionally refined grids into the global circulation. …”

The evolution and population genetics of hydrothermal vent megafauna from the Scotia Sea
Published 2013“…ESR and Southwest Indian Ridge kiwaids) is no earlier than 25.9 Ma, consistent with a spread from the Pacific into the Scotia Sea and beyond via now-extinct active ridge connections or mediated by a Miocene onset of the Antarctic Circumpolar Current (ACC) through a newly-opened Drake Passage.</p> <p>This project also investigated the population genetics of three undescribed species found at two vent fields ~ 440 km apart at either end of the ESR: <em>Kiwa</em> sp., a peltospirid gastropod and <em>Lepetodrilus</em> sp. limpets. …”

Eocene-Oligocene southwest Pacific Ocean paleoceanography new insights from foraminifera chemistry (DSDP site 277, Campbell Plateau)
Published 2022-11-01“…The negative Ce anomaly sharply increased two times at ∼35 and ∼31 Ma, indicating enhanced seawater ventilation synchronously with the opening of the Tasmanian and Drake Passage gateways, respectively. The Oligocene glaciation is recorded by a major increase of bottom seawater δ18O during the EOT (Eocene-Oligocene Transition) while Mg/Ca-temperatures remain rather constant. …”

A global view on stratospheric ice clouds: assessment of processes related to their occurrence based on satellite observations
Published 2022-05-01“…Gravity waves are mostly related to SICs at midlatitudes, especially over Patagonia and the Drake Passage. However, the second-highest correlation coefficients show that the cold tropopause temperature, the occurrence of double tropopauses, high stratospheric aerosol loading, frequent UTLS clouds, and gravity waves are highly correlated with the SICs locally. …”

Airborne glyoxal measurements in the marine and continental atmosphere: comparison with TROPOMI observations and EMAC simulations
Published 2023-01-01“…Observations of glyoxal in aged biomass burning plumes (e.g. observed over the tropical Atlantic off the coast of West Africa in summer 2018, off the coast of Brazil by the end of the dry season 2019, and the East China Sea in spring 2018) could be traced back to related wildfires, such as a plume crossing over the Drake Passage that originated from the Australian bushfires in late 2019. …”
