Findings from a new scientific study, indicates deep ocean warming is accelerated by Antarctic meltwater with long-lasting impacts on the climate.
This paper discusses the impact of Antarctic meltwater on ocean circulation. Abyssal ocean circulation refers to deep ocean currents, which play a crucial role in regulating the Earth’s climate by transporting heat, carbon, oxygen and nutrients throughout the world ocean.
According to the study, under a high-emissions scenario, the rate of warming in the deep ocean is projected to accelerate over the next 30 years due to the input of meltwater from Antarctica. This meltwater reduces the formation of Antarctic Bottom Water, a cold and dense water mass that plays a crucial role in regulating the Earth’s climate. As a result, the abyssal ocean will experience warming and ageing, with potential long-lasting implications for global ocean biogeochemistry and climate. Overall the paper highlights the importance of understanding and addressing the impact of Antarctic meltwater on ocean circulation. This knowledge can help inform strategies for mitigating and adapting to climate change.
