The National Science Foundation (NSF), under its Geosciences program (CFDA 47.050), awarded a $499,095 Project Grant to the University of Maryland, College Park. This award aims to develop a novel, miniature, fiber-optic multiparameter sensor (FOMS) capable of long-term, under-ice deployment to monitor greenhouse gas cycling within lakes.

The FOMS will simultaneously measure parameters critical for understanding a lake's influence on climate change, ecosystem health, and human impacts, including carbon dioxide, methane, temperature, pH, salinity, and dissolved oxygen. The project will also develop machine learning-based sensor calibration models to transform the FOMS into an intelligent sensing system. The data collected using stationary moorings and mobile underwater robotic platforms will inform a modeling framework to optimize future deployments and improve the quantitative understanding of greenhouse gas production, consumption, and transport in ice-covered lakes.
