“Addressing Computational Challenges in Earth Sciences with Advanced Technologies“

Wednesday 18 February 2026

Abstract

Earth Sciences New Zealand (ESNZ) brings together expertise spanning earthquakes, volcanic hazards, weather forecasting, biodiversity, and energy, land and water resource management, all united by a mission to deliver science that matters for Aotearoa New Zealand. Advanced technologies are increasingly central to translating this breadth of research into real-world outcomes for New Zealanders. We’ll highlight two recent examples that illustrate this technology-to-impact connection. First, we discuss real-time flood impact forecasting, using machine learning to emulate computationally demanding physics-based flood models – work that is already informing how communities receive and respond to flood warnings. Second, we present early investigations into the potential role of quantum computing for Earth science applications, including atmospheric chemistry and data assimilation optimisation problems.
