He was included in a cadre of technicians and engineers sent to the USA for training on the ATS System, which was carried out at the NASA Tracking Station at Rosman, N.C. In 1966 he was transferred to the NASA Applications Technology System Project for service at the Transportable Ground Station located near Toowoomba in Queensland. This lasted for 4 years and in that period Ken was promoted to Radar team leader, in charge of the operation and maintenance of a radar. He was then employed for about a year by IBM before joining AWA Ltd as part of a crew recruited to operate and maintain the AN-FPS 16 precision radars on the Weapons Research Establishment Range at Woomera in South Australia. He then served in HMAS Watson briefly before leaving the RAN in June 1961. He then served in HMAS Swan which carried out survey work on the Great Barrier Reef, as the senior radio and radar technician. In his time at HMAS Watson he passed a Fleet Board examination and was promoted to LREM. During this period he was promoted to REM2.Īfter eighteen months service in HMAS Anzac he was posted tot he RAN Radar Training School, HMAS Watson, located on the South head of Sydney Harbour where he served as senior technician with a staff of eight, maintaining several radar sets, many radar displays, HF, VHF, and UHF radio systems, and VHF Direction Finding equipment. Again he worked on radio and radar equipment, once more with an emphasis on Type 262 gunnery radar. He was then transfered to HMAS Anzac, a Battle Class destroyer. On completion of his training he joined HMAS Melbourne, an aircraft carrier, where he was employed on the maintenance of radio and radar, working predominantly on the Type 262 gunnery director radar.

He was sent to HMAS Cerberus and after his basic disciplinary training to the RAN Electrical School and trained there as a Radio Electrical Mechanic 3. On completion of his National Service he joined the RAN as a volunteer, agreeing to an initial engagement of six years. These projections will be of concern to the communities and policy makers of Lake George responsible for the management of the ecological and socio-economic systems.Ken was called up to carry out his National Service in the RAN in January 1955, He qualified as an Ordinary Seaman and Radar Plotter 3. Furthermore, by 2080–2,100 the mean air temperature is projected to warm up to +8.0 C under Representative Concentration Pathway 8.5. Using downscaled data from a coupled-climate model through to 2,100, projections with the trained classifiers suggest complete ice coverage will be a phenomenon of the past by the mid-to-late 21st Century. Simple machine learning classifiers are trained using local weather data to predict the presence of complete ice coverage on Lake George and are found to perform adequately compared to observations, with one configuration having an accuracy of 91%. For example, Lake George froze over in 19 despite the air temperature having a net warming effect on the lake in the month prior to ice-in. Over 60 years of meteorological observations from a nearby airport are analysed and a complicated picture emerges when considering the specific characteristics of each year. This transition from annual to intermittent ice cover is analogous to many other dimictic freshwater lakes globally.

Ice records at Lake George, an oligotrophic and dimictic freshwater lake in upstate New York, United States reveal that it has failed to freeze over completely 13 times since 1990.
