The Aeolotron

The largest active annular wind-wave tank in the world, the Aeolotron, is used to study small-scale exchange processes between the ocean and the atmosphere.

Mobile Laboratory of the VERIFY project

The mobile laboratory is used to monitor source-specific combustion gases (CO2, CO, CH4, NOx) in the atmosphere with the focus on domestic heating and traffic emissions.

High Alpine research station Jungfraujoch in the Swiss Alps

Since 1986, IUP is measuring here atmospheric 14CO2. Today the clean air station Jungfraujoch is part of the ICOS atmosphere station network.

Th/U Laboratory

Preparation of the samples for high-precision Th/U dating requires the chemical purification of both trace elements from natural samples.

Ocean Tracers

Climate driven cycles of heat and carbon in the ocean are studied through the use of trace isotopes such as radiocarbon.

Cold-Water Corals

Reef-forming cold water deep sea corals are a unique archive to study past ocean dynamics and climate.

MC-ICPMS Laboratory

Preparation of high-precision isotope measurements with semi-automated multi-collector inductively coupled plasma mass spectrometers.

detecting bubbles generated by breaking waves

Breaking waves and bubble clouds

Bubble clouds, generated by breaking waves, play a role in the exchange of gases between the ocean and the atmosphere. Bubble sizes are measured using imaging techniques.

ICOS CRL flask CO2 Extraction and Graphitization Line

The Karl Otto Münich Central Radiocarbon Laboratory of the European Research Infrastructure ICOS prepares atmospheric CO2 samples for 14C analysis by AMS.

measuring heat and gas transfer at the ocean

Air-Sea Interactions

Physical processes controlling the exchange of heat and gases between atmosphere and ocean as well as the properties of wind generated waves are studied using imaging techniques.

Speleothems

Stalagmites are an important archive to study past climate.

The rooftop atmospheric observatory

Measuring greenhouse gases and other atmospheric constituents above Heidelberg.

Radiocarbon Laboratory

Carbon dioxide extraction from speleothem samples and carbon graphitization to trace the past global carbon cycle.
