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.
cold water corals
Cold-Water Corals
Reef-forming cold water deep sea corals are a unique archive to study past ocean dynamics and climate.
Mobiles Labor für das VERIFY Projekt
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.
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.
stalagtites and stalagmites
Stalagmites are an important archive to study past climate.
Sampling water from the ocean.
Ocean Tracers
Climate driven cycles of heat and carbon in the ocean are studied through the use of trace isotopes such as radiocarbon.

The Aeolotron Wind-Wave Tank
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.
Th/U sample preparation
Th/U Laboratory
Preparation of the samples for high-precision Th/U dating requires the chemical purification of both trace elements from natural samples.
