Joe Hitchen, Oxford University Physics Department, describe the different stages of sea ice growth and the formation of hollow tubes of ice in the ocean known as brinicles. Every year, millions of square kilometres of the Arctic ocean freeze over as sea ice forms but this growth is controlled by processes on the scale of millimetres and centimetres. At this scale, sea ice is not a pure solid but a mixture of ice crystals and concentrated brine known as a "mushy layer". I will describe the different stages of sea ice growth and the formation of hollow tubes of ice in the ocean known as brinicles.

Sea Ice Growth: Mushy layers, Convection and Brinicles

Short talks from University of Oxford Physics Department. 



Contains episodes previously published as:

(1) 'Astrophysics: An Introduction'

(2) 'Lab, Camera, Action!': "Lab, Camera, Action! is a series of short videos presented by Dr Andrew Steele about physics, explaining basic concepts, the work done here in Oxford, and even some experiments to try at home. These engaging tutorials cover a range of topics from spectroscopy, superconductivity and the transit of Venus in a clear, accessible way which will appeal to science enthusiasts everywhere."

(3) 'Physics Flash Talks': 'A showcase of research at Oxford Physics through exciting 10 minute presentations delivered by graduate research students. The topics span the breadth of research at Oxford and include topics such as climate change, exoplanets, magnetism, the higgs and quantum computers.'
