Photographer Andrey Nekasov, 38,

Organisers from the Arctic Circle Dive Centre cut holes in the ice using hand-powered drills call borers.

Andrey added: 'Diving with the
belugas is really popular because they are so friendly. When we are
preparing to dive they pop their heads out and watch everyone getting
