The field team of Jamie Howarth (Victoria University), Sean Fitsimons (University of Otago) and Adelaine Moody (Victoria University) have just returned from sampling large/deep in central Canterbury – Lake Tekapo, Lake Ohau and Lake Pukaki. Using a special piece of equipment known as a Mackereth corer they collected cores up to 6 m in length. Photo credit: Pip Watt.
