SUMMARY:Hot Water Drilling 101 – How to drill through an ice shelf - Pau

DESCRIPTION:If you want to know what’s happening underneath an 800m thic
 k ice shelf then melting your way through using a hot water drill is the q
 uickest and easiest method. BAS has been engaged in hot water drilling act
 ivities for the past 25+ years using the technique to access the oceanic r
 egime beneath ice shelves across the continent. The Polar Oceans Shelf Sea
 s group is responsible for a number of different drilling systems tailored
  to various ice thicknesses and conditions ranging from shallow 100m thick
  Arctic ice shelves to deep 2000m+ thick Antarctic ice sheets. Whilst the 
 basic principle of hot water drilling and the equipment used is relatively
  straightforward\, persuading the various components to work together to p
 roduce a suitable access hole in a harsh polar environment presents a numb
 er of challenges. I’ll talk through these challenges\, the basic princip
 les of hot water drilling\, the various components that make up a drill sy
 stem and the detail the projects in which this technique has been used suc
 cessfully.
