Geothermal springs of NZ

The Stott lab team at GNS sampling Artist's Palette at Waiotapu (Matt, Caitlyn and Jean) 

The 'Map of Africa' feature at Orakei Korako. Lots of thermophilic amoebae found here!

Me and some sampling gear by Devil's Bath at Waiotapu.

Alum Cliffs (and a striking yellow arsenic deposit) at Waiotapu.

Frying Pan Lake, one of the largest geothermal lakes in the world at Waimangu Volcanic Valley. The temperature of this lake fluctuates between 50 and 60°C, making it a very interesting place to look for protists!

Devil's tongue feature at Orakei Korako geothermal field. Striking temperature gradation. 

 A cool example of selection... super hot stream (pink) flows into cooler one (green) and and only the heat tolerant (pink) microbes can survive. Stream rapidly cools and other life quickly appears again downstream.

A hot stream at Waiotapu.

Arsenic cave at Waiotapu.

Edge of Champagne pool, one of the most charismatic hot pools of New Zealand at Waiotapu.

Me at Waiotapu with sample from Alum cliffs arsenic deposit.
