“The bottom of the ocean is more of a “sunken place” than it used to be.
In recent decades, melting ice sheets and glaciers driven by climate change are swelling Earth’s oceans. And along with all that water comes an unexpected consequence â the weight of the additional liquid is pressing down on the seafloor, causing it to sink.
Consequently, measurements and predictions of sea-level rise may have been incorrect since 1993, underestimating the growing volume of water in the oceans due to the receding bottom, according to a new study.
In the new investigation, researchers looked at more long-term impacts to the seafloor. They evaluated how much the shape of the ocean bottom may have changed between 1993 and 2014, taking into account the amount of water added to the ocean from liquid formerly locked up on land as ice. Previous research into seafloor stretching had omitted that extra water, the scientists wrote in the study.
To do that, they reviewed approximations of mass loss on land, as the ice melted and drained into the oceans, and compared that to estimates of sea volume changes. They found that around the world for two decades, ocean basins deformed an average of 0.004 inches (0.1 millimetres) per year, with a total deformation of 0.08 inches (2 mm).
However, there were distinct regional patterns to the seafloor’s bending and stretching, and the amount of sag in certain parts of the ocean bottom could be significantly higher â as much as 0.04 inches (1 mm) per year in the Arctic Ocean, for a total of 0.8 inches (20 mm), the study authors reported.
As a result, satellite assessments of sea-level change â which don’t account for a sinking ocean bottom â could be underestimating the amount that seas are rising by 8 percent, according to the study.
The accuracy of future sea-level estimates could be notably improved if the sinking of the ocean floor were incorporated into the calculations, “either based on modelled estimates of ocean mass change, as was done in this study, or using more direct observations,” the scientists concluded.

The long-established MÄori system of environmental management is holistic. It is a system that ensures harmony within the environment, providing a process of, as well as preventing intrusions that cause permanent imbalances and guards against environmental damage. Kaitiakitanga is a concept that has “roots deeply embedded in the complex code of tikangaâ. Kaitiakitanga is a broad notion which includes the following ideas: guardianship, care, wise management.
