polar : (a) of or relating to a geographic pole or the region around it (b) coming from or having the characteristics of such a region — Webster
Polar regions of Earth also known as Earth’s frigid zones, are the regions of Earth surrounding its geographical poles (the North and South Poles). These regions are dominated by Earth’s polar ice caps, the northern resting on the Arctic Ocean and the southern on the continent of Antarctica. — Wikipedia

When people who haven't been to the Arctic think of this remote and cold region, they may picture animals, such as polar bears, narwhal or ringed seals, and the people who live there. Rarely does this vision include modern cargo ships and ocean liners.

Working in the Arctic Fram Strait, scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have found microplastic throughout the water column with particularly high concentrations at the ocean floor. Using model-based simulations, they have also found an explanation for this high level of pollution. According to their findings, the two main ocean currents in Fram Strait transport the microscopically small plastic particles into the region between […]

Owing to the excellent dispersion ability, diffraction gratings are playing an important role in widespread fields ranging from spectrometers to chirped pulse amplifiers. However, decades of extensive study on various broadband high-efficiency resonant gratings mainly focuses on those operating only at -1st order.
