Geology of Wisconsin: Survey of 1873-1879, Volume IV

Abstract

In the preface of the preceding volumes, sufficient explanation has been made of most matters requiring consideration in such connection. For reasons explained in the preface of Vol. III, and for others that have arisen since, the earlier portions of this volume have rested in type, awaiting the completion of the remainder, for a length of time much to be regretted. Consideration of this fact is due to the authors of Parts I, II and III. The atlas accompanying this volume includes, besides those relating to its subject matter, the general maps that more properly belong with Vol. I, with which no atlas will be issued. They are here included for economy and convenience of distribution. The maps accompanying Vols. II, III and IV are intended to be combined to form a single atlas. If bound in folio, as planned, it will be reduced to a convenient size.

Glacier modeling in support of field observations of mass balance at South Cascade Glacier, Washington, USA

The long-term USGS measurement and reporting of mass balance at South Cascade Glacier was assisted in balance years 2006 and 2007 by a new mass balance model. The model incorporates a temperature-index melt computation and accumulation is modeled from glacier air temperature and gaged precipitation at a remote site. Mass balance modeling was used with glaciological measurements to estimate dates and magnitudes of critical mass balance phenomena. In support of the modeling, a detailed analysis was made of the "glacier cooling effect" that reduces summer air temperature near the ice surface as compared to that predicted on the basis of a spatially uniform temperature lapse rate. The analysis was based on several years of data from measurements of near-surface air temperature on the glacier. The 2006 and 2007 winter balances of South Cascade Glacier, computed with this new, model-augmented methodology, were 2.61 and 3.41 mWE, respectively. The 2006 and 2007 summer balances were -4.20 and -3.63 mWE, respectively, and the 2006 and 2007 net balances were -1.59 and -0.22 mWE.
