Intertropical Convergence Zone limits climate predictions in the tropical Atlantic
The strongest climate fluctuation on time scales of a few years is the so-called El Niño phenomenon, which originates in the Pacific. A similar circulation pattern exists in the Atlantic, which scientists under the leadership of GEOMAR Helmholtz Centre for Ocean Research Kiel have studied in more detail. Their results, now published in the international journal Nature Communications, contribute to a better understanding of this climate fluctuation and pose a challenge for prediction models.

Dynamics in the root zone
Nutrient contamination of groundwater as a result of nitrogen-based fertilisers is a problem in many places in Europe. Calculations by a team of scientists led by the UFZ have shown that over a period of at least four months per year, nitrate can leach into the groundwater and surface water on about three-quarters of Europe's agricultural land. The proportion of areas at risk from nitrate leaching is thus almost twice as large as previously assumed. (2020-12-09)

Image-based navigation could help spacecraft safely land on the moon
In research recently published in the AIAA Journal of Spacecraft and Rockets, a multidisciplinary team of engineers demonstrated how a series of lunar images can be used to infer the direction that a spacecraft is moving. This technique, sometimes called visual odometry, allows navigation information to be gathered even when a good map isn't available. The goal is to allow spacecraft to more accurately target and land at a specific location on the moon without requiring a complete map of its surface. (2020-12-07)

The paper published today in the Philosophical Transactions of the Royal Society A. (2020-11-23)
