“…The days of least ablation (May 12) and of most ablation (June 12) can be compared with the Broughton Island data (Crane, 1979) using the latter study's period of least ablation and greatest ablation. For least ablation, our Hudson Bay data indicate a Q* that was half as great and a Q H and a Q E that were much smaller.…”

“…The most intensive previous study over fast ice has been documented by Barry and Jacobs (1978) and Crane (1979), both reporting on work carried out at Broughton Island, N. W.T., which lies in Davis Strait just off the east coast of Baffin Island.…”

“…In one case, the overlying air is cold and the ablation is retarded, whereas in the other, it is warm and a downward directed sensible heat flux hastens ablation melt. These studies make a further division into days with large net radiation and those with small net radiation (Crane, 1979). The period of study of ablation of fast ice off Broughton Island took place during June and July.…”

This study treats the energy balance during fast-ice and floating-ice conditions and examines overall seasonal patterns. The rate of ablation of the fast ice was controlled equally by net radiation and air temperature. The ratio of net/solar radiation increased 2.5 times during the ablation period owing to the decrease in ice albedo. Air temperature in the ablation zone was up to 8°C colder than that over the adjacent snow-free terrestrial surface and

“…Ron Weaver coordinated some of this work while I was on leave from 1975 to 1976, and this collaboration facilitated our subsequent work together at the World Data Center (WDC)-A for Glaciology. Later, Rob Crane utilized the data collected off Broughton to determine the synoptic controls of ablating fast ice (Crane, 1979).…”

Abstract. The paper traces my career as a climatologist from the 1950s and that of most of my graduate students from the late 1960s. These decades were the formative ones in the evolution of climate science. Following a brief account of the history of climatology, a summary of my early training, my initial teaching and research in the UK is discussed. This is followed by new directions at the University of Colorado, Boulder from October 1968. The history of the World Data Center for Glaciology/National Snow and Ice Data Center in Boulder from 1977 is described and climate-cryosphere initiatives at the Cooperative Institute for Research in Environmental Sciences (CIRES). International activities and links are then reported, followed by a section on national and international committees. I then describe my activities during sabbaticals and research leaves. The paper concludes with discussion of my "retirement" activities and an epilogue.

“…One such potential mechanism involves the noted high sensitivity of net radiation over Arctic snow surfaces to variations in cloudiness and surface albedo (e.g. Jaco~s and others, 1973;Ambach, 1974;Crane, 1979). These studIes concluded that, for a high-albedo snow surface net radiation under clear skies is significantly lower thad the corresponding value under cloudy skies with identical surface conditions.…”

ABSTRACT.Hourly measurements of incoming short-wave and long-wave radiation, surface albedo, and net radiation were made on and around a plateau ice cap on north-eastern Ellesmere Island during the summers of 1982 and 1983. These data were stratified by cloud type and amount. All cloud types increased incoming long-wave radiation, especially low dense clouds, fog, and clouds associated with snowfall. Relative transmission of incoming short-wave radiation, expressed as a percentage of clear-sky radiation receipts, was high for all cloud types compared to clouds at lower latitudes. With high surface albedo (~0.75), net radiation was strongly and positively correlated with net long-wave radiation but showed little relationship to net short-wave radiation. By contrast, with low surface albedo «(0.20) net radiation was negatively correlated with net long-wave radiation but positively correlated with net shortwave radiation. Under high-albedo conditions, an increase in cloudiness led to higher values of net radiation but under low-albedo conditions net radiation decreased as cloud cover increased. Survival of a snow cover would seem to be favoured if the seasonal decline in albedo is accompanied by a corresponding increase in cloudiness.
