lakes and will prepare charts of ice cover and ice characteristics as far as 
this is possible to establish from the air. It is planned to test experimental | 
infrared sensing devices to determine if they may be used for ice thickness 
measurement.. The utility of high altitude Air Force aerial photos and also 
_the satelite pictures are under study. 
Detailed ice surveys are sitiNed for the coming winter. Selected, 
rather small, ice fields will be surveyed for ice thickness, quality, color, 
strength, sina foreign materials. Concurrent observations will be made of x 
water and air temperatures, wind, and incoming and reflected radiant energy. 
Projects will be coordinated with Canadian Department of Transport, Univ- 
ersity of Michigan and to smaller extent with Public Health Service and 
Weather Bureau, ae appropriate. 
WATER QUALITY. Activities in this extremely broad field will be 
coordinated with the Public Health Service and other agencies. Lake Survey 
efforts at this time are quite limited. A network of water temperature recorders 
is being established this year. Ten highly sensitive recorders will be installed 
on U. S. shore of the Great Lakes. A similar project under the Canadian De- - 
partment of Transport will cover the’ Canadian waters. 
CURRENTS AND FLOWS. In the field of currents and flows, two projects 
- are in operation; one, the Hine tore in harbors and the other, surges and seiches. 
Three harbors in Lake Michigan were selected for the surveys of currents. 
A field party will trace the current moxemunts and recording instruments will
