who is the ross ice shelf named after
Ross Ice Shelf The ice shelf is named after Captain Sir James Clark Ross, who discovered it on 28 January 1841. It was originally called The Barrier, with various adjectives including Great Ice Barrier, as it prevented sailing further south. Ross mapped the ice front eastward to 160Â°W. In 1947, the US Board on Geographic Names applied the name Ross Shelf Ice to this feature and published it in the original US Antarctic Gazetteer. In January 1953 the name was changed to Ross Ice Shelf; that name was published in 1956.[4][5]
Refrigerator The first practical vapor compression refrigeration system was built by James Harrison, a British journalist who had emigrated to Australia. His 1856 patent was for a vapor compression system using ether, alcohol or ammonia. He built a mechanical ice-making machine in 1851 on the banks of the Barwon River at Rocky Point in Geelong, Victoria, and his first commercial ice-making machine followed in 1854. Harrison also introduced commercial vapor-compression refrigeration to breweries and meat packing houses, and by 1861, a dozen of his systems were in operation.
