Melting of Greenland and Antarctic ice sheets is one of the main responses to the rising atmospheric greenhouse gas concentrations. It will potentially have a destabilizing effect on the large-scale ocean circulation, imposing interhemispheric climate change over the next decades to centuries. Assessing the intensity of the climate anomalies driven by ice-sheet melting and ocean circulation slowdown is necessary for accurate climate change predictions, and thus paramount for tracing climate adaptation strategies.

Dr. Aguiar is an oceanographer and postdoctoral researcher at the Physical Oceanography Division at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML). Dr. Aguiar’s research is cross-disciplinary, focusing on past and future changes in the Global Meridional Overturning Circulation and the carbon cycle in response to buoyancy fluxes in high latitudes of the North Atlantic and the Southern Ocean. His main tools to understand dynamical and biogeochemical processes in the ocean are Earth System Models, ocean observations, and paleoclimate cores (especially through oxygen isotope ratios). He has expertise in configuring and running the Modular Ocean Model (MOM6), CESM, and UVic model.

Current Work

Dr. Aguiar’s current research aims to investigate how ice shelf melting in the Southern Ocean affects local and global ocean circulation, and to understand how melting processes (e.g., Calving and Basal Melting) are represented in Earth System Models forced by virtual freshwater fluxes.
