Up to 12 different prey fish species were sampled with a 12-m bottom trawl during April, July, and September along two Lake Huron transects (Thunder Bay, Hammond Bay). At each transect in each month, two replicate 10-min tows were conducted at each of three depths (18, 46, 82 m) during the day and night. Once the fish were onboard in a given tow, they were sorted to species, weighed (in aggregate), and up to 50 individuals per species were measured to the nearest total length.

The study area is located ~40 km southeast of downtown Tucson, and is bounded by the Rincon Mountains on the north, the Empire Mountains on the southeast, and the northernmost Santa Rita Mountains on the southeast. The map area covers the southern part of the Vail 7 ½' Quadrangle, including all the Paleozoic rocks in the Colossal Cave area. Field mapping was completed during October 2000 through April 2001 as part of a multiyear mapping program directed at producing complete geologic map coverage for the Phoenix-Tucson metropolitan corridor. A 1:24,000 scale map is the primary product of this study (Plate 1). This map consists almost entirely of new mapping but locally incorporates data from published mapping by...

These files contain scans of Topographic Reconnaissance maps of Antarctica. The source maps were published at 1:250,000-scale by the U.S. Geological Survey in cooperation with the National Science Foundation. The extent of their coverage can be seen in the “Topographic Reconnaissance Index - 250k” layer of the Atlas of Antarctic Research viewer. Use the “VIEW” link below to look at a low resolution version of the map. Then download the selected map at full resolution by clicking the download link. The metadata for each of the maps is contained in the “Full Map”download file. The maps were scanned at a ground resolution of 25.4 meters and range from 10 to 30 megabytes.They are provided in two formats: Full Map ...
