PhD student Johanne Vad (back, right) conducting fieldwork in Greenland, in association with the CALVE marine project. Johanne ‘s focus was the collection of Greenland subtidal sponges during shallow water dives within kelp forests and in the vicinity of maerl beds. The aim of the work is to collect, identify and study sponge sensitivity to oil contaminated seawater, as interest of oil companies in offshore drilling in Greenland is increasing.

The Leverhulme funded research program CALVE “Calving Glaciers: long term evidence and validation” attempts to utilize terrestrial and marine proxies to recreate movements of a large tide water glacier in southwestern Greenland, Kangiata Nuňata Sermia (KNS). The marine team focuses on a proxy which reconstructs temperature and salinity of the marine environment utilizing schlerochronolgy and composition of coralline algae skeletons (the abundance and ratios of Mg, Ca, and O primarily). Target species are called maerl, which are free living species that grow in 360˚ and create diverse habitats in areas of high current in the marine-fjord transition zone near the KNS glacier.
