Open ocean polynyas: How these holes in the ice mysteriously appear
For decades now scientists have been fascinated by polynyas, holes that appear in the polar sea ice whose causes are still unclear. Recent data from robots that recorded two of these cavities opening sheds light into how they are formed. Shawn WangI am a PhD student studying climate physics and marine geology at MIT and […]
Icebergs Fertilize Phytoplankton Growth
Icebergs contain iron, the limiting nutrient for phytoplankton in the polar regions. Icebergs, therefore, have the potential to stimulate biological productivity and carbon uptake. However, this will depend on the iceberg iron content, which is not well known. Therefore, a recent study sought to quantify the variability in iceberg iron content and subsequent carbon uptake. […]
