Great collaboration with @NORCEresearch and @sios_svalbard in the context of my SIOS-Access project GLASS. We managed to survey all glaciers in the Brøggerhalvøya peninsula (Svalbard) with a hyperspectral sensor in order to map glacier algae and cryoconite!

ICEBOOST is a machine learning model that generates ice thickness maps for any of the world's glaciers.

It is trained with 3.7 million data. Its error is up to 40% lower than existing models.

In machine learning, a model can be guided by data in several ways.

However, if the model can generalize well enough, it doesn't care about extra data.

Modeling deep ice canyons in Greenland. Big circles are measurements.

Gradient Boosted Trees.

The ice distribution of the Aletsch glacier, Switzerland, modeled with a multi-layer peceptron. The circles are the measurements.

The distance between a point inside a glacier and the glacier borders may be a powerful predictor for the ice thickness at that location.

The distance calculation has to account for the presence of nunataks (regions with no ice, blue).

Aletsch and sorrounding glaciers.

Map of surface latitude slope over the Aletsch glacier in the eastern Bernese Alps, along with randomly generated locations inside the glacier perimeter.

I am investigating how good the slope can be as a predictor of ice thickness when fed to Graph neural network.

Today my second Marie Curie Fellowship starts with @CaFoscari, @uciess, @NASAJPL

The SKYNET project goal: better constrain the ice volume of Earth's glaciers, using generative AI.

We address the question: "can neural nets support humans in detecting particles in paleo records - ice and beyond ?"

The elevation pattern of mars.
Data: Mars Orbiter Laser Altimeter (MOLA)

** Mars has no sea level - the altitude scale has therefore another zero. The zero is Mars gravitational and rotational equipotential surface, called aeroid.

@TerribleMaps From an algorithm perspective, try to fit as many switzerland as possible inside a fixed region, being allowed to rotate switzerland but not overlap. Maximization problem. Whoever created the map has been thinking.

[Niccolò Maffezzoli @nico_maffe]

In the process of investigating to which extent #NeuralNetworks can predict subglacial topographies and ice volumes in high-mountain Asia glaciers.

Quando il ghiaccio sparì dal Nord Atlantico
@cnrisp e @CaFoscari dimostrano che nell’ultima era glaciale-nel Nord Atlantico-le riduzioni di ghiaccio marino si verificarono nell’arco di 250 anni in concomitanza con eventi di rapido aumento delle temperature
