Emiliano Cimoli
UTas
Current ACEAS Activities:

Sea-ice algal biomass and cryogenic minerals are two poorly constrained properties of Antarctic sea ice that propagate directly into Southern Ocean estimates of primary production and carbon export. Ice-associated biomass and pigments are still quantified through destructive coring and melting, sparse in space and slow to process. Cryogenic gypsum, precipitating in sea-ice brines and increasingly hypothesised to ballast phytoplankton on release during melt, is even less well known, with no Antarctic assessment yet despite a seasonal ice cycle large enough to influence carbon export. My contribution to ACEAS is to make both measurable with the same tools.

 

Drawing on approaches from ocean colour and geological remote sensing, I am adapting shortwave-infrared hyperspectral imaging with machine learning and field-deployable computing to retrieve biomass, pigments and cryominerals from ice-core sections, filtered melt samples and under-ice survey, at the scales at which they vary. My ongoing contribution is methodological, proving these approaches so they are ready for the next round of national programs and voyages, and the resulting quantities feed Theme 2 estimates of Southern Ocean productivity and carbon export. Over 2026 to 2028 this delivers a led paper on the hyperspectral and AI/ML workflow, FAIR-archived imagery integrated into Seamap Antarctica, and an open-source code release. I will also deliver versioned SOPs, bring the new AAD Specim FX-fusion scanning station and ship-mounted camera into routine operation, and train students and staff so the capability is voyage-ready for the upcoming marginal ice zone campaign and aligned Antarctica InSync and BEPSII activities.
