By some fortunate encounters and decisions, Adam Kerr found himself charting the seas of both the Antarctic and Arctic. This work was carried out first for the Falkland Island Government (now the British Antarctic Survey) and later for the Canadian Government. His period of charting polar seas was a core to much wider activity which involved the development of new navigational technology. In his later years, he worked as a Director of an international organisation that focuses on the safety and well-being of all those who work at sea. Throughout his career as a chart maker, he had parallel interests in fine art, recreational fishing and sailing. This book contains fascinating insights into what lies hidden beneath the polar seas in regions where temperatures sometimes drop as low as -62 C."
