Andrew T Fisher

About

Professor Andrew T. Fisher is a faculty member in Earth and Planetary Sciences at UC Santa Cruz, specializing in hydrogeology. His research focuses on groundwater systems, hydrothermal circulation, and coupled fluid-heat-solute flows. He leads hydrogeology simulations, including projects supported by NASA that model hydrothermal systems on ocean worlds. His work encompasses the study of the hydrogeology and thermal evolution of oceanic crust, including ridge flanks, seamounts, and convergent margins. Additionally, he investigates groundwater recharge processes, managed recharge strategies, and the development of associated incentives and tools. Professor Fisher and his group also focus on water resources, including supply and quality, and the development and testing of new tools and methods for hydrogeological research. The UCSC Hydrogeology Group, which he is part of, explores these topics through numerical simulation and field studies, contributing to a deeper understanding of subsurface fluid dynamics and their implications for both Earth and planetary sciences.

• Numerical Simulation of Cool Hydrothermal Processes in the Upper Volcanic Crust Beneath a Marine Sediment Pond: North Pond, North Atlantic Ocean

  Journal of Geophysical Research Solid Earth · 2021 · 10 citations

  Abstract Low temperature hydrothermal systems hosted in the volcanic oceanic crust are responsible for ∼20% of Earth's global heat loss. Marine sediment ponds comprise an important type setting on young ridge flanks where hydrothermal circulation advectively extracts lithospheric heat, but the nature of coupled fluid‐heat transport in these settings remains poorly understood. Here we present coupled (fluid‐heat) numerical simulations of ocean crustal hydrogeology in and below North Pond, a sedim…

• Toward Natural Language Generation by Humans

  Proceedings of the AAAI Conference on Artificial Intelligence and Interactive Digital Entertainment · 2015 · 10 citations

  Natural language generation (NLG) has been featured in at most a handful of shipped games and interactive stories. This is certainly due to it being a very specialized practice, but another contributing factor is that the state of the art today, in terms of content quality, is simply inadequate. The major benefits of NLG are its alleviation of authorial burden and the capability it gives to a system of generating state-bespoke content, but we believe we can have these benefits without actually e…

• Recharge net metering (ReNeM) is a novel, cost-effective management strategy to incentivize groundwater recharge

  Nature Water · 2023-10-18 · 9 citations

  articleOpen access

  Abstract Managed aquifer recharge, which uses available water to augment groundwater resources, holds promise as a strategy to reduce chronic groundwater overdraft. However, water management agencies often confront hurdles when implementing managed aquifer recharge. Favourable sites for recharging water are often located on private land, and common-pool resource conflicts frequently disincentivize voluntary private participation. We introduce recharge net metering (ReNeM), a conceptually novel,…
