An Australian national science agency called CSIRO launched an experiment in antarctica that went terribly wrong – in a way that ended up going wonderfully right. A free-floating ocean robot was sent to collect data from the Totten Glacier. Though, a current pulled it away from its destination and westward. It ended up in a place vrey difficult for scientists to analyze, and it returned with extremely rare and valuable data.
The ocean float has salinity and temperature sensors and was meant to go below the water and surface once every 10 days to transmit its data to satellites. Robots like these are used frequently in ocean research and sometimes for measuring the impact of climate change on the waters and glaciers. This specific one was meant to study the Totten Glacier in regards to how much the global sea levels could rise if the glacier melted.# Lost Robot Reveals Troubling Data About Antarctic Glaciers
A robot ocean float, initially lost beneath the ice of Antarctica, has returned with crucial data about the melting rates of the Denman glacier and Shackleton Ice Shelf. The robot traveled under the denman Glacier and the Shackleton ice shelf, diligently measuring water salinity and temperature from the seafloor up to the base of the ice. Unable to surface and transmit data directly, its location became a mystery to the research team.
However, the robot left a trail. Each attempt to surface resulted in the float bumping the underside of the ice shelf, allowing it to measure the ice’s depth. By comparing this data to satellite measurements, researchers were able to reconstruct the robot’s path and pinpoint the origin of its 195 collected data profiles.
The data revealed a concerning disparity: while the Shackleton Ice Shelf appears safe from warm water intrusion for now, the Denman Glacier is being actively melted from below by warmer currents. This is particularly alarming, as the Denman Glacier alone holds the potential to raise global sea levels by nearly 5 feet. This revelation underscores the urgency of understanding these vulnerable areas, especially as some climate change damage may already be irreversible, and the world’s coastlines are facing significant danger.
## What this means for future science
The successful recovery of data from this lost robot demonstrates a novel approach to gathering facts in challenging environments. It highlights the potential for autonomous underwater vehicles to provide valuable insights into the dynamics of glaciers and ice shelves, even when direct communication is unfeasible.This method could be crucial for monitoring vulnerable areas and improving predictions of future sea level rise.
