In winter, cold water masses in the North Atlantic sink from the sea surface into the deep ocean. This process, known as convection, is one of the key components of the large-scale ocean circulation. Based on long-term observations, scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel have now demonstrated the influence of increased surface freshening in summer on convection in the following winter. As the researchers write now in the international journal Nature Climate Change, enhanced surface freshening and warmer winters have significantly shortened the duration of ocean convection in the last decade.

How Much Snow Accumulates in North America Each Year? More Than Scientists Thought
There’s a lot more snow piling up in the mountains of North America than anyone knew, according to a first-of-its-kind study.
Lack of Water is Key Stressor for Urban Trees
A recent study finds that urban trees can survive increased heat and insect pests fairly well – unless they are thirsty. Insufficient water not only harms trees, but allows other problems to have an outsized effect on trees in urban environments.
Flood, Drought and Disease Tolerant – One Gene to Rule Them All
An international collaboration between researchers at the University of Copenhagen, Nagoya University and the University of Western Australia has resulted in a breakthrough in plant biology. Since 2014, the researchers have worked on identifying the genetic background for the improved flood tolerance observed in rice, wheat and several natural wetland plants. In a New Phytologist, article, the researchers describe the discovery of a single gene that controls the surface properties of rice, rendering the leaves superhydrophobic.
A laser focus on super water-repellent metals
In a laboratory at the University of Rochester, researchers are using lasers to change the surface of metals in incredible ways, such as making them super water-repellent without the use of special coatings, paints, or solvents.
