PalaeOpen
PalaeOpen: Open Palaeoecological Data – analysing the past building foresight
COST Action CA23116 | 2024–2028 | Group member: Anna Tichá
A European network bringing palaeoecological data into the public domain, harmonising them and making them useful for nature conservation.
A case study on productivity, ocean ventilation and carbonate dissolution from the S-SE Brazilian Margin – insights for marine carbon storage.
Estudo de caso sobre produtividade, ventilação oceânica e dissolução de carbonato na margem continental sul e sudeste brasileira – insights para o armazenamento de carbono marinho.
Funded by: FAPESP 2022/03830-3
Collaboration with Prof. Karen B. Costa, University of São Paulo | Filip Scheiner as a partner investigator
This project studies palaeoceanographic sites along the south-eastern Brazilian continental margin to better understand processes that control carbon storage in the ocean. It tests whether the geometry of bottom water masses, together with enhanced productivity and organic matter flux, may act together to affect carbon storage, combining ¹⁴³Nd/¹⁴⁴Nd, Cd/Ca, Zn/Ca and δ¹¹B with micropalaeontological indices.

Seagrass/seaweed meadows – overlooked Phanerozoic ecosystems: their contribution to shelf biodiversity and identification in the fossil record
Funded by: Czech Science Foundation 23-05217S | PI: Katarína Holcová
Seagrass and seaweed meadows are important but overlooked biodiversity hotspots, yet they rarely fossilise. This project combines palaeontology and organic geochemistry to develop indirect markers for recognising them in the fossil record, and evaluates their contribution to shelf biodiversity through the Phanerozoic.
The Langhian Mediterranean-Paratethys enigma: hydrography based on Nd isotopes proxy on foraminifera revealing changes in paleoceanography
Funded by: Czech Science Foundation 20-05872S | PI: Katarína Holcová | Collaboration with Dr Lukáš Ackerman, Institute of Geology, CAS
This project reconstructs oceanographic interactions in the Mediterranean-Paratethys system during the closure of the Indian-Mediterranean gateway in the Middle Miocene. It combines high-precision Nd isotope analyses on foraminifera with Mg/Ca, δ¹⁸O and δ¹³C, together with palaeoecological and sedimentological approaches.
