Possibly counterintuitively, sediment layers are most likely to stay undamaged on the seafloor than on land, so they can offer a much better record of the area’s history. The seafloor is a more steady, oxygen-poor environment, minimizing disintegration and decay (2 factors researchers discover much more fossils of marine animals than land occupants) and protecting finer information.

Samples from various locations differ drastically in time protection, returning just to 2008 for some and back possibly more than 15,000 years for others due to extremely various sedimentation rates. Researchers will utilize methods like radiocarbon dating to identify the ages of sediment layers in the core samples.

Tiny analysis of the sediment cores will likewise assist the group evaluate the method the eruption impacted marine animals and the chemistry of the seafloor.

“There’s a variety of life and sediment types discovered at the various websites we surveyed,” stated Alastair Hodgetts, a physical volcanologist and geologist at the University of Edinburgh, who took part in the exploration. “The earliest location we checked out– a location scarred by ancient glacier motion– is a fossilized seascape that was totally unforeseen.”

This function, too, informs researchers about the method the water relocations. Currents streaming over a location that was deteriorated long earlier by a glacier sweep sediment away, keeping the ancient surface noticeable.

“I’m really thinking about evaluating seismic information and associating it with the layers of sediment in the core samples to produce a timeline of geological occasions in the location,” stated Giulia Matilde Ferrante, a geophysicist at Italy’s National Institute of Oceanography and Applied Geophysics, who co-led the exploration. “Reconstructing the past in this method will assist us much better comprehend the sediment history and landscape modifications in the area.”

The group has actually currently collected measurements of the quantity of sediment the eruption provided to the sea. Now they’ll work to identify whether older layers of sediment record previously, unidentified occasions comparable to the 2008 eruption.

“Better understanding past volcanic occasions, exposing things like how far an eruption reached, and how typical, serious, and foreseeable eruptions are, will assist to prepare for future occasions and minimize the effects they have on regional neighborhoods,” Watt stated.
