Exceptionally rapid onset of coastal upwelling offshore Peru- Kiel marine scientists find significant changes in the eastern Pacific during the past 10,000 years

The coastal upwelling of cold and nutrient-rich waters off Peru and Ecuador is significant not only for the regional fishing industry, but also for the global carbon cycle and thus for the Earth's climate. As part of the Kiel Collaborative Research Centre 754, scientists of the GEOMAR Helmholtz Centre for Ocean Research Kiel examined how this system has developed and changed in the past. Their work showed that coastal upwelling only began there ~10,000 years ago, and then continuously expanded northward along the South American coast.

Ocean warming leads to stronger precipitation extremes

Recent event underlines importance of study by German and Russian scientists
Due to climate change, not only atmospheric, but also oceanic, temperatures are rising. A study published in the international journal Nature Geoscience led by scientists at the GEOMAR Helmholtz Centre for Ocean Research Kiel shows that increases in sea surface temperature can contribute to the development of stronger precipitation events. Their findings are underpinned by flash-flooding in June in the Olympic city of Sochi, Russia.

Scientists will use robots to explore deepest ocean

SCIENTISTS from the Oban-based Scottish Association for Marine Science (SAMS) will use custom-built robots to explore the deepest parts of the ocean in a bid to discover how life is sustained thousands of metres below the surface. 

The Southeast Pacific produces more nitrous oxide than previously thought - Kiel marine scientists publish new data on greenhouse gas emissions

In addition to carbon dioxide there are plenty of other greenhouse gases. Nitrous oxide is one of them. However, a global assessment of emissions from the oceans is difficult because the measurement methods used so far have only allowed rough estimates. Using a new technology for continuous measurements, researchers of the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Christian-Albrechts-Universität zu Kiel have now discovered that nitrous oxide emissions from the Southeast Pacific are much higher than previously thought.

Scottish scientists unearth effects of mining waste disposal

SRSL expertise to reduce environmental impact on seabed

 

Researchers from the independent Scottish Association for Marine Science (SAMS), near Oban, and its commercial partner SAMS Research Services Ltd (SRSL) conducted surveys in Papua New Guinea into the effects of deep-sea tailings placement (DSTP) on seabed biological communities.
