In 2015, a research project began to monitor the long-term movements an d volume changes of this ice deposit and to understand the microclimate of the cave. With two expeditions organized in October 2015 and September 2016, a complete study of the cave was carried out using a 3D laser scanner HDS7000 in 2015 and a scanner ScanStation P40 in 2016. Installation of barometric datalodgers, temperature and humidity in different areas of the cave provide a one-year record of the microclimate. In addtion, pollen traps have been installed to study the current flow of pollen on and inside the cave while preliminary analyzes of pollen grains held in the ice are in progress. The Cenote Abyss Ice Caves Research Project aim to shed light on the changing climate of the Dolomites over the past several hundred years, perhaps thousands of years, as well as on environmental changes more recent events that led to the melting of the cave glacier.
