30,000 years of landscape and vegetation dynamics in a mid-elevation Andean valley
McMichael, Chrystal; Witteveen, Nina; Scholz, Simon; Zwier, Maaike; Prins, Maarten; Lougheed, Bryan C.; Mothes, Patricia; Gosling, William D. (Journal article; Peer reviewed, 2021)The mid-elevation settings of the Andes are important biodiversity hotspots, yet little is known of their long-term ecology or environmental change. Here, we assess 30,000 years of landscape and vegetation dynamics on an ... -
Holocene changes in the position of the Southern Hemisphere Westerlies recorded by long-distance transport of pollen to the Kerguelen Islands
Zwier, Maaike; van der Bilt, Willem Godert Maria; Schneider, Tobias; D'Andrea, William J.; Bakke, Jostein; Van der Putten, Nathalie; Bjune, Anne Elisabeth (Journal article; Peer reviewed, 2024)The Southern Hemisphere Westerlies (SHW) are a vital part of the Southern Hemisphere's coupled ocean-atmosphere system and play an important role in the global climate system. The SHW affect the upwelling of carbon-rich ... -
Pollen evidence of variations in Holocene climate and Southern Hemisphere Westerly Wind strength on sub- Antarctic South Georgia
Zwier, Maaike; Bilt, Willem Godert Maria van der; de Stigter, Henko; Bjune, Anne Elisabeth (Journal article; Peer reviewed, 2021)The Southern Hemisphere Westerlies (SHW) play a major role in the global climate system. The winds drive ocean circulation and affect the Southern Oceans’ ability to take up atmospheric CO2. Recently, the SHW core belt has ... -
Stable Southern Hemisphere westerly winds throughout the Holocene until intensification in the last two millennia
van der Bilt, Willem Godert Maria; D’Andrea, William J.; Oppedal, Lea Toska; Bakke, Jostein; Bjune, Anne Elisabeth; Zwier, Maaike (Journal article; Peer reviewed, 2022)The Southern Hemisphere westerly winds sustain the Southern Ocean’s role as one of Earth’s main carbon sinks, and have helped sequester nearly half the anthropogenic CO2 stored in the ocean. Observations show shifts in the ... -
Winds of change : A multi-proxy approach to constrain Holocene climate and wind dynamics in the sub-Antarctic
Zwier, Maaike (Doctoral thesis, 2024-09-05)Kunnskap om tidligere tiders naturlige klimavariasjoner er hovednøkkelen for å forstå vår nåværende klimatilstand. Det er også viktig for å kunne vurdere omfanget og retningen til fremtidige klimaendringer som forventes ...
