Hinsoddau Oer

The cold climate research group unites cross-disciplinary scientists in the School of Earth and Ocean Sciences who are interested in processes in some of the most extreme environments on Earth.

Our studies develop insights into the state, behaviour and dynamics of Earth system processes in the polar regions through a combination of field research, laboratory experimentation and numerical modelling.

We are interested in how life exists in extreme environments and how processes in the coldest places influence the workings of the whole Earth.

Aims

We aim to understand the causes and consequences of change in the Earth system by using glaciology, biogeochemistry, microbiology, palaeoceanography and palaeoecology.

Specialist low temperature environmental simulation cabinets

The cold climate laboratory has Weiss Low Temperature simulation cabinets, which can mimic conditions in some of the most extreme environments on Earth. We can control light, temperature (-40°C to +80°C) and gas content.

Precision titration facilities

We use Unisense optodes and electrodes to measure oxygen and pH at the microscale.

Field measurement of meteorological, water and biogeochemical parameters

We can measure and log a variety of biogeochemical parameters (pH, EC, light) using Campbell Scientific data loggers and associated probes in the laboratory and in the field.

We use a Fast Rapid Rate Fluorometer (Photon Systems Instruments 3500F) to measure the photophysiology of microalgae and cyanobacteria cultured in our Weiss Low Temperature cabinets. The FRRF can measure photoacclimation as well as standard proxies of productivity and down regulation.
