About
Alison Gray is an oceanographer who studies the circulation of the ocean and its impact on the physics and chemistry of the climate system. She uses observations from many different sources, including profiling floats, gliders, satellites, and ships, to investigate the dynamics of the ocean circulation on a variety of scales. Her research also aims to improve our understanding of the interactions between ocean circulation and global biogeochemical cycles.

The Southern Ocean carbon and climate observations and modeling (SOCCOM) project: A review
Progress In Oceanography · 2023 · 56 citations
The Southern Ocean serves as the primary gateway through which the intermediate, deep, and bottom waters of the ocean interact with the surface ocean (and thus the atmosphere), and it has a profound influence on the oceanic uptake of anthropogenic carbon and heat as well as nutrient resupply from the abyss to the surface. Yet it has been the least observed and understood region of the world ocean. The Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) project was implemented in…
Indo‐Pacific Sector Dominates Southern Ocean Carbon Outgassing
Global Biogeochemical Cycles · 2022 · 41 citations
Abstract The Southern Ocean modulates the climate system by exchanging heat and carbon dioxide (CO 2 ) between the atmosphere and deep ocean. While this region plays an outsized role in the global oceanic anthropogenic carbon uptake, CO 2 is also released to the atmosphere across large swaths of the Antarctic Circumpolar Current (ACC). Southern Ocean outgassing has long been attributed to remineralized carbon from upwelled deep water, but the precise mechanisms by which this water reaches the su…
Observational Evidence of Ventilation Hotspots in the Southern Ocean
Journal of Geophysical Research Oceans · 2021 · 37 citations
Senior authorCorrespondingAbstract Standing meanders are a key component of the Antarctic Circumpolar Current (ACC) circulation system, and numerical studies have shown that these features may locally enhance subduction, upwelling, as well as lateral and vertical tracer transport. Yet, observational data from these regions remain sparse. Here, we present results based on measurements made by a group of autonomous platforms sampling an ACC standing meander formed due to the interaction of the Polar Front with the Southwes…
The Four-Dimensional Carbon Cycle of the Southern Ocean
Annual Review of Marine Science · 2023-09-22 · 28 citations
reviewOpen access1st authorCorrespondingThe Southern Ocean plays a fundamental role in the global carbon cycle, dominating the oceanic uptake of heat and carbon added by anthropogenic activities and modulating atmospheric carbon concentrations in past, present, and future climates. However, the remote and extreme conditions found there make the Southern Ocean perpetually one of the most difficult places on the planet to observe and to model, resulting in significant and persistent uncertainties in our knowledge of the oceanic carbon c…
Journal of Atmospheric and Oceanic Technology · 2023-01-19 · 13 citations
articleAbstract Global estimates of absolute velocities can be derived from Argo float trajectories during drift at parking depth. A new velocity dataset developed and maintained at Scripps Institution of Oceanography is presented based on all Core, Biogeochemical, and Deep Argo float trajectories collected between 2001 and 2020. Discrepancies between velocity estimates from the Scripps dataset and other existing products including YoMaHa and ANDRO are associated with quality control criteria, as well…
