Patricia Jean Langhorne NZAM (born 1955) is a British-New Zealand Antarctic sea ice researcher.

For a time she led the observational component of one of New Zealand’s National Science Challenges – the Deep South.

From there she moved to Clare Hall[3] at the University of Cambridge, UK, where she completed her PhD in 1982, under the supervision of Peter Wadhams, on crystal alignment in sea ice.

This resulted in collaboration on examining the strength of sea ice with Bill Robinson, Vernon Squire and Tim Haskell.

[5] The work was published in Nature and underpinned the use of sea ice runways for large aircraft.
