IFAA 2024, Sponsorship and Patronage

Thank you for your support!

The 13th International Symposium on Fossil Algae has the patronage of the Società Geologica Italiana and Società Paleontologica Italiana, and of the International Fossil Coral and Reef Society. Moreover, we are grateful to the International Association of Sedimentologists for a sponsorship in the framework of the IAS sponsored conference initiative.

Oceano aMICO2


In Milan, for the first time, two important academic institution (Università Milano-Bicocca and Politecnico di Milano) are teaming together to host the Oceano aMICO2 event. This is a divulgative event on CO2 reduction strategies centered around the Ocean. The theme is extremely relevant and the strategies discussed may shape the new mitigation of current climate change scenarios.

In the flyer you will find the link to subscribe to the event.

The initiative is open to everyone including school teachers, students and curious!

The initiative will be in Italian

here’s the link to follow the event remotely: https://politecnicomilano.webex.com/politecnicomilano-it/j.php?MTID=m911d89fd218eb8f543beb71d232e2195

EGU 2023

The CresciBlu team was in Wien for the EGU 2023 conference! During this time we have presented some of our work so far and shared our results with the huge and welcoming European Geological community! It was a blast!


Everybody was in Milano-Bicocca for the work-in-progress meeting of the CBR project. Extremely happy and satisfied for all the work! Stay tuned for the next updates!

During the coring operation, high stability is required due to the brittleness of the coralligenous samples.  In order to reach this stability, the ROV has to be firmly anchored to the reef surface. Hence, we designed an ad hoc anchoring system by testing different types of screw: the common ones used for wood, self-drilling screws, and finally drill bits commonly used for concrete and metals. The first two options failed because an excessive axial force was needed and the resulting thread was not able to withstand enough pulling force. Instead, the last option seemed to be the best since it allows easier penetration in the material. Then, a specifically designed test rig was used to find the current consumption and the axial thrust required to penetrate in the coralligenous sample.

However, drill bits alone are not sufficient to assure vertical force resistance so we are going to mate them with a rubber expansion sleeve. Once the holes are made, a mechanism is going to move up just the tip of the screws that is opportunely constrained to it by a sphere on the top. Hence, each rubber sleeve is going to be compressed and will expand providing sufficient grip with the sidewalls of the holes.

Specific tests already validated such a system but we cannot wait to try it underwater!
