A VALUE OF BIOMINERAL'S ARCHIVE
Seasonal Temperatures and Acidification of sensitive Marine settings:
Insight of an uNmatched macro-invertebrate Archive
TEMPERATURE AND pH
Keys chemico-physical factor for life
An enhancement in the amplitude of the seasonal cycle of sea surface temperature and in the ocean acidification is expected in the next decades as consequences of human-induced carbon dioxide injection in the atmosphere. Marine organisms, particularly those that build calcium carbonate shells and skeletons, will undergo enormous physiological challenges, threatening the future of ocean ecosystems. Unfortunately, the high uncertainty about the future evolution of the chemical-physical condition of the ocean undermine actions to mitigate the anthropogenic impact. Can we obtain a better estimation of the risks?
FOSSILS AS CLIMATE ARCHIVE
Quantifying future changes looking onto the past
Knowing history to understand the present and, therefore, to defend and build the future has always been an established assumption. Brachiopods, uncommon elements of the modern marine ecosystem, were widespread during the deep time of Earth, i.e. the Palaeozoic era. As fossils, they are archives of past climatic condition, unexperienced by humanity. Studying their growth and chemical composition in present and past specimens will allow a more precise understanding of the future evolution of the ocean and pursue action to mitigate global warming.
ABOUT BRACHIOPODS
"Brachiopods constitute one of the most intriguing and challenging phyla groups that can be studied by paleontologist"
- 1968, Sir Alwyn Williams.
"Predominantly sessile, filter-feeding marine invertebrates, with a ciliated, tentaculate feeding organ or lophophore and a bivalved shell"
- 2007, Bernard L. Cohen
"the microstructure of the brachiopod shell is so intimately bound up with the metabolism of the living organism as to be of profound importance systematically"
- 1972, C. Howard C. Brunton
"It is vitally important that we reach a better understanding of the processes governing morphology in such a paleontologically important group in which well over 95% of species are extinct"
- 2016, Sandra J. Carlson

At the Department of Earth Sciences, people are actively involved in broad and far-reaching research activities encompassing a wide range of temporal and spatial scales.
CLAUDIO GARBELLI, Ph.D.
Nature always fascinated me. During the school years, my favourite topics were Biology, Chemistry and Geology. Alongside the academic route, I was fortunate to encounter great mentors who intrigued by speaking about Biological Evolution and the Geobiological History of the Earth. I am now surer than in the past that knowledge derived by Natural Sciences is among the best resources to understand the role of men in the biosphere's theatre.
I obtained the PhD in Natural and Environmental Sciences at the University of Milan in 2015, and I was an MSCA fellow at the University of Cambridge from April 2021 to April 2023.
