A Neanderthal's specialised burning structure compatible with tar obtention

Here we present multiproxy evidence of a new type of Neanderthal hearth discovered in Vanguard Cave (VC) (Gibraltar), which is dated ∼ 65 kyr, and ass…

Isn’t it cool, as a paleoclimate #scientist, to co-author this new #archaeological #scientific #publication first-authored by Juan Ochando?
https://doi.org/10.1016/j.quascirev.2024.109025
With Belen Martrat and Barend van Drooge at IDAEA-CSIC and Joan Villanueva, Oriol Teruel, and me at ICTA-UAB.

I am honored to co-author the new #scientific #publication first-authored by Petter Hällberg! This time, it is the use of #levoglucosan rather than #GDGTs—as #paleohydrology rather than #paleotemperature #ClimateProxies this time!—which granted me this #collaboration and co-authorship!

Disentangling seasonal and annual precipitation signals in the tropics over the Holocene: Insights from δD, alkanes and GDGTs

Rainfall seasonality in the tropics has a substantial impact on both ecosystems and human livelihoods. Yet, reconstructions of past rainfall variabili…

My first first-authored #scientific #publication as a former #postdoc at ICTA-UAB, published in #Journal of #Chromatography A one year and a half ago, deserves a #thread on #Mastodon as well!
We selectively extract #levoglucosan and its isomers from complex matrices, such as #sediments, for quantification by liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS)!

Selective extraction of levoglucosan and its isomers from complex matrices using ligand exchange-solid phase extraction for analysis by liquid chromatography-electrospray ionization-tandem mass spectrometry

The analysis of trace quantities of monosaccharide anhydrides (MAs) in sediments is complicated by the lack of fast and reliable technologies to selec…

To all #EGU24-goers (in #person and #virtual), I will have not one, but two first-authored #presentations on Tuesday 16 April 2024 in two different, non-EOS #sessions.
Ergo, one of my two first-authored presentations is a solicited one.
