Scientists study the glacier melting risk in Greenland

This week, an international team of 80 scientists and crew will embark on the RSS David Attenborough to sail for Greenland in order to determine whether the melting glaciers on the island could affect the climate and currents in the Atlantic Ocean. The mission, which will last five to six weeks, leaves Britain, after Western Europe and Britain experienced their warmest month of June on record. This caused power outages, closed schools, and increased deaths. Kelly Hogan, marine geophysicist with the British Antarctic Survey, which is leading this mission, said in an interview aboard the vessel that the heatwaves in Europe and the UK in recent months had really made it clear how difficult it was for us to adjust to even small changes in climate. The expedition is a part of a PS20million project called GIANT – Greenland Ice Sheet to AtlaNtic Tipping Points - that aims to better understand the melting and breaking down of glaciers into the ocean, and their impact. Scientists worry that the melting of freshwater may disrupt a rotating ocean current system which regulates Europe's climate. This could lead to extreme weather conditions and higher sea levels. Matt Neill is a ship captain who has made several trips to Antarctica, including his first as a cadet in 2011. He says he's seen first-hand the effects of climate change. "Lots are of glaciers all?receding extremely quickly and more than you think." He said that it is more important now than ever to collect data and improve models during these dynamic times.

BOATY MBOATFACE

Officially, the ship was named after veteran naturalist Attenborough. But to many Britons, it will forever be "Boaty McBoatface" after this suggestion won a 2016 public poll.

Named instead for a high-tech submersible that will be on the vessel, it will dive to 1500 meters below the glacier mixture - a mix of sea ice & snow that forms where the glacier meets the sea. It will map its geometry and how it affects the glacier. Sam Smith, an operations engineer with the National Oceanography Centre said that it would be collecting data never before collected.

The data collected will be used to create next-generation climate model and a system of early warning for glacier failure.
