An expanded Oligocene-Miocene boundary interval recovered in the Cape Roberts Project CRP-2A core from beneath the Ross Sea, Antarctica, has yielded a high-resolution integrated chrono stratigraphy that has, in turn, enabled a new, more direct, calibra tion of magnetic polarity and biostratigraphic events. The Oligocene-Miocene boundary interval in the CRP-2A core comprises three ∼60-m-thick, rapidly deposited (>0.5 m/k.y.) sedimentary sequences (sequences 9, 10, and 11). In sequences 10 and 11, single-crystal, laser-fusion 40Ar/39Ar analyses of anorthoclase phenocrysts from two tephra horizons independently calibrate the CRP-2A magnetic-polarity stratigraphy and age model. Sequences 10 and 11 encompass subchron C6Cn.3n, which is dated as 24.3 ± 0.1 to 24.16 ± 0.1 Ma. Sequence 9 is interpreted to encompass subchron C6Cn.2n and the Oligocene-Miocene boundary, which is dated as 24.0 ± 0.1 Ma. These ages are ∼0.2 m.y. older than those of the geomagnetic polarity time scale calibrated from seafloor-spreading ridges and ∼0.9–1.3 m.y. older than the newly proposed astronomically calibrated ages. We contend that the discrepancy with the astronomically calibrated ages arises from a mismatch of three 406 k.y. eccentricity cycles or a 1.2 m.y. modulation of obliquity amplitude in the astronomical calibration of the Oligocene–Miocene time scale.
The draw threw up the possibility of a Clasico semi-final, with Barcelona and Madrid on collision course to meet in the last four should both make it that far. The other side of the draw is clearer. First-time quarter-finalists RB Leipzig of Germany will meet Atletico Madrid, runners-up to city rivals Real the last time the Champions League final was played in Lisbon in 2014. Atletico knocked out holders Liverpool in the last 16. The winners of the Leipzig v Atletico quarter-final will face either Paris Saint-Germain or Atalanta in the last four. The quarter-finals will be played between August 12 and 15 in the Portuguese capital, with matches shared between Benfica’s Estadio da Luz and Sporting’s Estadio Jose Alvalade. The semi-finals are scheduled for August 18 and 19, with the final on August 23 at the Estadio da Luz.

The situation in Lisbon itself is particularly concerning, with lockdown restrictions reimposed last week on 19 neighbourhoods across the northern periphery of the city as virus cases increase at a worrying rate. FacebookTwitterWhatsAppEmail分享 Barcelona and Bayern Munich will meet in the quarter-finals of the UEFA Champions League should both sides make it through, Friday’s draw for the final eight confirmed. Both teams still need to complete their last-16 ties, with Bayern almost there having won 3-0 away to Chelsea in the first leg, while Barcelona are due to host Napoli after a 1-1 draw in Italy. Meanwhile, if Manchester City can finish the job in their last-16 tie against Real Madrid, Pep Guardiola’s team will go on to a quarter-final against either Juventus or Lyon. City won 2-1 in Madrid in the first leg in March, while Juventus must overturn a 1-0 deficit from the first leg of their last-16 tie against Lyon. Postponed in March as the pandemic took over, all remaining last 16 second legs are due to be played on August 7 and 8. The winners will advance to the Final Eight, which will be held as a unique straight knockout tournament in Lisbon due to the difficulties caused by the coronavirus.

Vroon is confident that the envisaged restructuring will provide a generous runway to implement its strategic plans,” Vroon said.The agreement is subject to final documentation and credit committee confirmation.The company’s restructuring was prompted by an overall downturn in the maritime industry, driven in particular by offshore oil and gas.Namely, Vroon’s offshore-support-vessel subsidiary Vroon Offshore Services was heavily impacted by a reduction in demand, resulting from the severe downturn. However, the company said that its other businesses were all performing in line with expectations.Now that the restructuring agreement has been reached, Vroon said it would continue to keep its focus on measures aimed at strengthening its financial structure.Vroon is active in several shipping business sectors and its fleet of 200 vessels includes livestock carriers, offshore-support vessels, dry-cargo and container vessels, product/chemical tankers, asphalt/bitumen tankers and car carriers.The company employs 350 staff at its shore-based facilities and around 2,800 marine personnel worldwide.
