Mystery of Siberian freshwater seal food choice solved

(Research Organization of Information and Systems) Seals native to Siberia’s Lake Baikal have been found to have a remarkable adaptation in their teeth that has allowed them to prosper even in the face of limited nutrient offerings.

Ice sheets on the move: How north and south poles connect

Over the past 40,000 years, ice sheets thousands of kilometers apart have influenced one another through sea level changes, according to new research. New modelling of ice sheet changes during the most recent glacial cycle demonstrates, for the first time, that during this period, changes in the Antarctic ice sheet were driven by the melting ice sheets in the Northern Hemisphere.

Evidence of the interconnectedness of global climate

(Harvard University) The analysis, published in Nature, shows for the first time that changes in the Antarctic ice sheet were caused by the melting of ice sheets in the Northern Hemisphere. The influence was driven by sea-level changes caused by the melting ice in the north during the past 40,000 years.

A rich source of nutrients under the Earth’s ice sheets

Trace elements such as iron and zinc are essential micronutrients for all kinds of organisms. Below ice sheets, which cover around ten percent of the Earth’s land surface, larger quantities of these substances are mobilised than previously assumed. This is shown by new data from Greenland and Antarctica, which were collected and analysed by an international research team.

Shift in atmospheric rivers could affect Antarctic sea ice, glaciers

Weather systems responsible for transporting moisture from the tropics to temperate regions in the Southern Hemisphere have been gradually shifting toward the South Pole for the past 40 years, a trend which could lead to increased rates of ice melt in Antarctica, according to new research.

New clues shed light on importance of Earth’s ice sheets

(Florida State University) Researchers examining subglacial waters both from Antarctica and Greenland found that these waters have higher concentrations of important, life-sustaining elements than previously thought, answering a big unknown for scientists seeking to understand the Earth’s geochemical processes.

Plastic pollution is everywhere. Study reveals how it travels

A study reveals the mechanism by which microplastics, like Styrofoam, and particulate pollutants are carried long distances through soil and other porous media, with implications for preventing the spread and accumulation of contaminants in food and water sources.
