AWI’s underwater robot Tramper successfully recovered

On 27 August 2017, deep-sea researchers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) recovered the underwater robot Tramper, which had been taking measurements at a depth of 2435 metres for nearly 60 weeks – the first long-term mission involving a crawler under the Arctic sea ice. For the first 24 weeks, the robot took biogeochemical readings at various sites, just as it was intended to. Unfortunately, because of a broken tread, Tramper got stuck in the same place in January, though it continued to record the…

Polar 6 is the first German research aircraft to traverse the North Pole

At 2:10 pm UTC on 22 August 2017, the Polar 6 became the first German research aircraft to fly over the North Pole. The aircraft “departed from (10:11 am UTC) and returned to (5:00 pm UTC) Station North (81.5°N, 16W)”, as Dr Thomas Krumpen reported in an email sent from Greenland.

New findings on the past and future of sea ice cover in the Arctic

Temperatures in the Arctic are currently climbing two to three times faster than the global average. The result – and, thanks to feedback effects, also the cause – is dwindling sea ice. In a study published in the actual volume of Nature Communications, geo- and climate researchers at the Alfred-Wegener Institute, Helmholtz Centre for Polar- and Marine Research (AWI) show that, in the course of our planet’s history, summertime sea ice was to be found in the central Arctic in periods characterised by higher global temperatures – but less CO2 – than today.

Underwater robot scheduled to surface after a year exploring the Arctic depths

On Tuesday, 22 August the research icebreaker Polarstern will depart the Norwegian port of Tromsø for a unique expedition to the Arctic: the autonomous underwater robot TRAMPER is scheduled to resurface, after a full year of deep-sea exploration in the Arctic. It and other robotic systems jointly designed by deep-sea and aerospace researchers in the context of the Helmholtz Alliance ROBEX will now undergo nearly three weeks of testing under real-world operating conditions. The purpose of ROBEX is to develop new technologies for exploring remote regions…

Into the unknown - high altitude research aircraft explores the upper levels of the Asian Monsoon

The Asian Monsoon System is one of the Earth’s largest and most energetic weather systems, and monsoon rainfall is critical to feeding over a billion people in Asia. An international team of scientists led by the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) is now conducting the first-ever scientific mission to the upper levels of the monsoon system, using a high-altitude research aircraft flying out of Nepal. The results will help to better understand how this important weather system affects global climate and how it…

Time to rise and shine

The copepod species Calanus finmarchicus schedules its day using a genetic clock that works independently of external stimuli. The clock shapes the copepod’s metabolic rhythms and daily vertical migration. This in turn have an enormous influence on the entire food web in the North Atlantic, where Calanus finmarchicus is a central plankton species. Wherever the high-calorie copepod is, determines where its predator species are. The results of the study will be published in the journal Current Biology.

Antarctic biologists meet in Belgium

Antarctic scientists from all over the world meet in Leuven, Belgium, from July 10th to 14th. “Scale matters” is the overarching theme of the 12th biology symposium organized by SCAR, the Scientific Committee on Antarctic Research. From the small molecular scale, through population and large ecosystem scale, biological processes and diversity span all these levels, and the contributions are accordingly variable.

Falling sea level caused volcanos to overflow

Throughout the last 800,000 years, Antarctic temperatures and atmospheric carbon dioxide concentrations showed a similar evolution. However, this was different during the transition to the last ice age: approximately 80,000 years ago, temperature declined, while the carbon dioxide content of the atmosphere remained relatively stable. An international research team led by the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Alfred-Wegener-Institute Helmholtz Centre for Polar and Marine Research has now discovered that a falling sea level may have…
