2020 Photo competition shortlist
In July 2020 all members of the Geoscience Society of New Zealand were invited to show off their photographic talent. The competition was split into three categories to commemorate the centennial of Milutin Milanković’s astronomical theory: Théorie mathématique des phénomènes thermiques produits par la radiation solaire.
The categories were:
1. Milankovich: Geological Cyclicity
2. Macro- and micro-scale geoscience
3. New Zealand Geoscience.
The shortlisted images in each section are shown below.
GSNZ members are able to vote for their preferred image in each section using the link provided in the 29 July Newsflash.
Voting closes on 14 August and the winners announced shortly after.
Milankovich: Geological Cyclicity
Interbedded sandstone and conglomerate of the Cretaceous Rewanui Formation, West Coast, South Island.
Glen Valtos, Western Lewis, Outer Hebrides, 2016. The road passes through a winding meltwater channel, carved beneath an ice sheet by water flowing eastward from a dammed lake of ice. This ice, on melting, drained down this glacial spillway. Past glaciations record evidence of cyclical temperature fluctuations.
Macro & micro-scale geoscience
New Zealand Geoscience
Te Mari Upper Crater Fumarole, Tongariro, 2020.
Mid-Cretaceous intrusion, Mt Tapuae-o-Uenuku, Marlborough.
Lake Johnson, 2020: the coring team dances about the boat as they try to find their footing and prepare to retrieve another sediment core, spoilt with their Queenstown scenery.
A long vapour trail left by a commercial jet hangs over Egmont Volcano and Fanthams Peak. The sun has set behind the main volcanic cone and low cloud is beginning to accumulate on the eastern slopes of the mountain.
