Autonomous detection of ice core particles via deep learning
The presence of insoluble particles in ice cores carry fingerprints of multiple aspects of Earths past climate. Mineral dust records allow the investigation of dust source emissions, atmospheric transport and wind strength variability. Volcanic ash (cryptotephra) particles are emitted during eruptio...

The presence of insoluble particles in ice cores carry fingerprints of multiple aspects of Earths past climate. Mineral dust records allow the investigation of dust source emissions, atmospheric transport and wind strength variability. Volcanic ash (cryptotephra) particles are emitted during eruptions and deposited as individual layers in the ice. Their detection and characterization is fundamental for reconstructions of past volcanism and as a method to date and synchronize different sedimentary records, such as marine or terrestrial cores. Pollen grains and biological matter are often found in alpine glacial ice records at mid latitudes and are proxies for ecosystem changes and vegetation dynamics. To date, the analytical detection of these particles is often based on intensive manual microscopic investigations and require multiple laborious and often destructive extraction steps. Here, we present an analytical framework that can overcome these limitations, based on flow imaging microscopy coupled to deep learning neural networks for the autonomous detection and quantification of dust, volcanic tephra and pollen grain particles. The network architecture structure joins a Resnet-backbone Convolutional Neural Network and a Fully Connected Net and is trained in supervised mode.
