In 1992 the Geological Survey of Greenland (GGU) initiated the project SUPRASYD in order to carry out an economic assessment of the Ketilidian orogen in South Greenland, especially the supracrustal rocks in the southern and eastern parts of the orogen (see Dawes & Schønwandt, 1992). Geological investigations in the area east of Nanortalik and along the east coast of South Greenland as far as 62°N had previously indicated that acid metavolcanic rocks were an important constituent of the supracrustal rocks, and it was therefore expected that the region might have a significant potential for sulphide deposits.

Old, archived geologic maps are often available with little or no associated metadata.  This creates special problems in terms of extracting their data to use with a modern database.  This research focuses on some problems and uncertainties associated with conflating older geologic maps in regions where modern geologic maps are, as yet, non-existent as well as vertically integrating the conflated maps with layers of modern GIS data (in this case, The National Map of the U.S. Geological Survey).   Ste. Genevieve County, Missouri was chosen as the test area.  It is covered by six archived geologic maps constructed in the years between 1928 and 1994. Conflating these maps results in a map that is internally consistent with these six maps, is digitally integrated with hydrography, elevation and orthoimagery data, and has a 95% confidence interval useful for further data set integration.

As a first stage in planning a regional mapping programme on the south-east coast of Greenland from Scoresby Sund to Kap Farvel, the available material from previous expeditions has been examined and a provisional geological map is being compiled. A programme of isotopic age determination has been started in collaboration with F. J. Fitch (London University) and J. A. Miller (Cambridge University) in order to help localise areas in which to concentrate future detailed geological mapping. The Geological Survey of Greenland will be very pleased to receive information gathered on recent expeditions to this coast which may be of help in planning and which could prevent a senseless dupliaation of effort.

In the course of conversation with Professor J. Park, the Director of our School of Mines. I first heard of the occurrence of a gigantic pedunculated Cirripede in certain Tertiary deposits on the east coast of the North Island of this colony. I then wrote to Mr. T. F. Cheeseman, the Curator of the Auckland Museum, in which some remains were exhibited: in answer to my request, Mr. Cheeseman very generously loaned me these remains, and the following notes are founded on them. I will here express my thanks to this gentleman for the readiness with which he has, in this and other instances, complied with my request for the loan of specimens out of his museum. But these few fragments do not represent all that is known of the animal; for I understand that abundant material, collected by Professor Park during his geological survey, is entombed in boxes in the Colonial Museum at Wellington, and Professor Thomas, of Auckland, also possesses, as he informs me, a fair supply of valves, collected by himself.I have, however, not been able to examine either of these collections. And although the present contribution is very incomplete, yet I hope that it will stimulate the possessors of better material to supplement or correct my remarks; at any rate, it will serve to direct the attention of European geologists and zoologists to the existence in late geologic times of a Cirripede remarkable chiefly for its gigantic size, far surpassing any member of the group hitherto, known to science.

Purpose The purpose of this study was to investigate the relationship between oral language, literacy skills, age, and dialect density (DD) of African American children residing in two different geographical regions of the United States (East Coast and Midwest). Method Data were obtained from 64 African American school-age children between the ages of 7 and 12 years from two geographic regions. Children were assessed using a combination of standardized tests and narrative samples elicited from wordless picture books. Bivariate correlation and multiple regression analyses were used to determine relationships to and relative contributions of oral language, literacy, age, and geographic region to DD. Results Results of correlation analyses demonstrated a negative relationship between DD measures and children's literacy skills. Age-related findings between geographic regions indicated that the younger sample from the Midwest outscored the East Coast sample in reading comprehension and sentence complexity. Multiple regression analyses identified five variables (i.e., geographic region, age, mean length of utterance in morphemes, reading fluency, and phonological awareness) that accounted for 31% of the variance of children's DD—with geographic region emerging as the strongest predictor. Conclusions As in previous studies, the current study found an inverse relationship between DD and several literacy measures. Importantly, geographic region emerged as a strong predictor of DD. This finding highlights the need for a further study that goes beyond the mere description of relationships to comparing geographic regions and specifically focusing on racial composition, poverty, and school success measures through direct data collection.
