Edmond's research has shown that the ocean absorbs vast amounts of carbon dioxide from the atmosphere, mitigating the impacts of climate change. However, as atmospheric carbon dioxide levels continue to rise, the ocean's ability to absorb carbon dioxide is diminishing. This leads to ocean acidification, which can have severe consequences for marine organisms and the entire marine ecosystem.

Edmond's research has also highlighted the role of the biological pump in regulating atmospheric carbon dioxide levels. The biological pump refers to the process by which marine organisms convert carbon dioxide into organic matter, which is then exported to the deep ocean. Edmond's work has shown that the efficiency of the biological pump is influenced by a variety of factors, including ocean temperature and nutrient availability.

The practical applications of Edmond's research on climate change are far-reaching. His work has helped to inform policy decisions on climate change mitigation and ocean conservation. It has also provided valuable data for scientists who are studying the impact of climate change on marine ecosystems and developing strategies to adapt to its effects.

Bermuda Atlantic Time-series Study (BATS)

Trevor Edmond played a pivotal role in the establishment and implementation of the Bermuda Atlantic Time-series Study (BATS), a long-term oceanographic research program that has revolutionized our understanding of the ocean's role in the global carbon cycle and climate change. Begun in 1988, BATS is the longest-running time-series study of biogeochemical and physical properties of the ocean in the world.

BATS has been instrumental in providing scientists with a comprehensive dataset to study the seasonal and interannual variability of the ocean's physical, chemical, and biological properties. This data has been essential for understanding the role of the ocean in absorbing carbon dioxide from the atmosphere, as well as the impact of climate change on the ocean's ecosystems.

One of the most important findings from BATS is that the ocean is absorbing more carbon dioxide from the atmosphere than previously thought. This has helped to slow the rate of climate change, but it has also led to ocean acidification, which can have harmful effects on marine ecosystems.

The data from BATS has also been used to study the impact of climate change on the distribution of marine organisms. For example, scientists have observed a northward shift in the distribution of some fish species, as well as changes in the abundance of certain types of phytoplankton.

The BATS program has made significant contributions to our understanding of the global carbon cycle and climate change. The data collected from BATS has been used to develop climate models and to inform policy decisions on climate change mitigation and ocean conservation.

Ocean acidification

Ocean acidification is a serious threat to marine life and ecosystems worldwide. It is caused by the increasing levels of carbon dioxide in the atmosphere, which are absorbed by the ocean and cause a decrease in pH. Trevor Edmond's research has been instrumental in raising awareness about ocean acidification and its potential consequences.

Decreased pH
As the ocean absorbs more carbon dioxide, its pH decreases, making it more acidic. This can have a negative impact on marine organisms, particularly those with calcium carbonate shells or skeletons, such as corals and shellfish.
Reduced calcification
Ocean acidification can make it more difficult for marine organisms to build and maintain their shells and skeletons. This can lead to weaker shells and skeletons, making them more vulnerable to damage and predation.
Shifts in species distribution
Ocean acidification can cause shifts in the distribution of marine species. Some species may move to areas with less acidic water, while others may become extinct.
Impacts on food chains
Ocean acidification can disrupt food chains by affecting the availability of food for marine organisms. For example, ocean acidification can reduce the growth of phytoplankton, which are a food source for many marine animals.
