A Nigerian geoscientist, Yusuf Azeez has joined a cohort of researchers studying the Antarctica for the stability of methane hydrates and the evolving morphology of the seafloor in response to rising global temperature.
This is contained in the progress report of the research made available to LEADERSHIP in Ilorin, Kwara State.
Yusuf, a doctoral researcher at Texas A&M University-Corpus Christi (TAMU-CC), joined other researchers in an international expedition to the Ross Sea, one of the most dynamic marine environments in the Southern Ocean.
He said the collective aim of visiting one of Earth’s most remote and environmentally critical regions was to investigate how polar regions were responding to climate change and what this translates to global carbon cycling.
The research, supported by a $1.7m grant from the U.S. National Science Foundation brought together a multidisciplinary team of oceanographers, climate scientists, and marine geophysicists.
”We are focused on methane hydrates, frozen deposits of methane beneath the ocean floor that are highly sensitive to temperature changes.
“If destabilised, these hydrates could release large quantities of methane, a greenhouse gas far more potent than carbon dioxide, into the atmosphere,” Yusuf said.
The Nigerian geoscientist said understanding where and how this happens was vital to refining climate projections.
”Using high-resolution bathymetric mapping, seismic profiling, and sub-bottom sonar technologies, the team identified zones of sediment deformation and possible gas seepage (clues to past and potentially active methane release).
“These findings will contribute to global efforts to track sources and sinks of greenhouse gases and improve the accuracy of predictive climate models,” he said.
Yusuf said the research outcomes will inform international climate assessments and help policymakers anticipate risks associated with rapid environmental shifts in polar systems.
Beyond the technical work, the expedition served as a training platform for early-career scientists, with Yusuf contributing to knowledge exchange in geophysical survey techniques, data interpretation, and environmental modeling.
