    The onset of neoglaciation in Iceland and the 4.2 ka event 
    Geirsdóttir, Áslaug; Miller, G H; Andrews, John Thomas; Harning, David; Anderson, Leif S.; Florian, Christopher; Larsen, Darren; Thordarson, Thorvaldur (Copernicus GmbH, 2019-01-08)
    Strong similarities in Holocene climate reconstructions derived from multiple proxies (BSi, TOC – total organic carbon, δ13C, C∕N, MS – magnetic susceptibility, δ15N) preserved in sediments from both glacial and non-glacial lakes across Iceland indicate ...

    Response of biological productivity to North Atlantic marine front migration during the Holocene 
    Harning, David John; Jennings, Anne E.; Köseoglu, Denizcan; Belt, Simon T.; Geirsdóttir, Áslaug; Sepúlveda, Julio (2021-02-08)
    Marine fronts delineate the boundary between distinct water masses and, through the advection of nutrients, are important facilitators of regional productivity and biodiversity. As the modern climate continues to change, the migration of frontal zones ...

    The Saksunarvatn Ash and the G10ka series tephra. Review and current state of knowledge 
    Óladóttir, Bergrún Arna; Thordarson, Thorvaldur; Geirsdóttir, Áslaug; Jóhannsdóttir, Guðrún Eva; Mangerud, Jan (Elsevier BV, 2020-03)

    Tracking Holocene drift-ice limits on the northwest–southwest Iceland shelf: Comparing proxy data with observation and historical evidence 
    Andrews, John Thomas; Jónsdóttir, Ingibjörg; Geirsdóttir, Áslaug (Informa UK Limited, 2019-01-01)
    We detail variations in the weight percent (wt%) of quartz, a proxy for drift ice, in fifteen marine sediment cores from the northwest, west, and southwest Iceland shelf throughout the past 10 cal ka BP. We present the first map of iceberg distributions ...
