Nannoworks alumni and University of Toronto postdoctoral fellow, Dr. Jose Dominick Guballa returned to Room 014 for a Nannochats presentation on his research chapters on “Coccolithophore assemblage composition during the Greenland Interstadial–Stadial 20 transition and their response to the Youngest Toba Tuff (YTT) supereruption ∼74,000 years ago in the northeastern Arabian Sea”.
The Toba supereruption originating from Toba Lake in Sumatra, Indonesia was thought to have triggered a positive feedback loop towards a stadial period. To prove this, coccolithophore assemblages relating to the layer of the Youngest Toba Tuff supereruption were studied to account for changes in the climate. It was found that the supereruption did impact assemblages briefly but did not become a cause for climate change.
The presentation was then followed by a visit to the Sedimentology Laboratory for a short presentation on the various fossils being studied in the laboratory, endearingly lead by the “Nannoverts Group”. The sauropod and pterosaur fossils shown in the photo are replicas, but the common interest in all kinds of fossils is real as shown in the picture below.
