In September 2019, a team of 600 researchers from 19 countries united in a common mission known as MOSAiC--the Multidisciplinary drifting Observatory for the Study of Arctic Climate--whose mission is to chart conditions in the Arctic for one continuous year. This illustrated account of that incredible voyage features amazing images from acclaimed photographer Esther Horvath, who documents every step of the expedition. Learn how researchers prepare for the journey with survival training. Watch as they plow through the ice and set up a network of research stations that drift along on a floe across the North Pole. See them take ice samples, measure wind and temperature, and study every element of the atmosphere, terrain, and ocean to obtain data that will help shape the course of climate science for generations to come. Horvath's camera captures life on board the vessel, visits by curious polar bears, the wonders of the Arctic sky, the endless waves of wind-blown snow and ice, and the beauty and ferocity of some of the most brutal conditions on earth. Accompanying these pictures are texts and commentary by researchers taking part in the expedition. This stunning book offers a front-row seat to the most important climate research project in recent history and helps readers grasp why studying the Arctic is essential to our survival on this planet.
