Scientists Warn of 'Flying Blind' Without US Ocean Monitoring System

The Threat to Ocean Monitoring

The Trump administration's plan to dismantle an ocean observation system vital to understanding the climate crisis and marine ecosystems would “severely degrade” the accuracy of weather predictions and El Niño forecasts, with economic consequences for the US, European and American scientists have warned.

The Ocean Observatories Initiative

The Ocean Observatories Initiative (OOI), run by the US National Science Foundation, is a vast network of seafloor systems, underwater gliders and moored surface platforms that feeds data to researchers, policymakers, educators and mariners worldwide. The initiative, which covers both US coastlines and extends into the North Atlantic and Southern Ocean, has been used to study marine heatwaves, harmful algal blooms, subduction zone earthquakes, ocean acidification and fisheries variability.

The Data Analysis

Decommissioning the US system, which plays a major part in a global ocean observation network, would lead to a massive increase in error in the annual estimates of ocean heating rates, according to research published last month. Removing US observations alone would produce a 163% increase in error for annual ocean heating rates.

The Impact Analysis

The loss of US observations, in a year predicted to be an El Niño year, with “supercharged” weather extremes, could also “lose the ability to see it coming clearly to act in time”. The stakes are concrete: farmers in the US and across South America use El Niño forecasts to decide what to plant and when – whether to expect drought or flooding shapes every agricultural decision months in advance.

The Prediction

“The US government wants to save less than a billion in sensors, which are the eyes and ears of the ocean” said Abrahams. “We have hundreds of billions in climate costs per year. The cost of the observation system is a fraction of the climate costs from hurricanes and storms that hit the US. ” The system, is, Abraham said is “quite an inexpensive way to reduce climate-related costs”.
