Predicting water quality by relating secchi-disk transparency and chlorophyll a measurements to Landsat satellite imagery for Michigan inland lakes, 2001-2006
L. M. Fuller, R. J. Minnerick
2007, Fact Sheet 2007-3022
The State of Michigan has more than 11,000 inland lakes; approximately 3,500 of these lakes are greater than 25 acres. The USGS, in cooperation with the Michigan Department of Environmental Quality (MDEQ), has been monitoring the quality of inland lakes in Michigan through the Lake Water Quality Assessment monitoring program....
Protocol for Landsat-Based Monitoring of Landscape Dynamics at North Coast and Cascades Network Parks
Robert E. Kennedy, Warren B. Cohen, Alan A. Kirschbaum, Erik Haunreiter
2007, Techniques and Methods 2-G1
Background and Objectives As part of the National Park Service's larger goal of developing long-term monitoring programs in response to the Natural Resource Challenge of 2000, the parks of the North Coast and Cascades Network (NCCN) have determined that monitoring of landscape dynamics is necessary to track ecosystem health (Weber and...
Radiometric recalibration procedure for Landsat-5 Thematic Mapper data
Gyanesh Chander, Esad Micijevic, Ronald W. Hayes, Julia A. Barsi
2007, Conference Paper
The Landsat-5 (L5) satellite was launched on March 01, 1984, with a design life of three years. Incredibly, the L5 Thematic Mapper (TM) has collected data for 23 years. Over this time, the detectors have aged, and its radiometric characteristics have changed since launch. The calibration procedures and parameters have...
Using a remote sensing/GIS model to predict southwestern Willow Flycatcher breeding habitat along the Rio Grande, New Mexico
James R. Hatten, Mark K. Sogge
2007, Open-File Report 2007-1207
Introduction The Southwestern Willow Flycatcher (Empidonax traillii extimus; hereafter SWFL) is a federally endangered bird (USFWS 1995) that breeds in riparian areas in portions of New Mexico, Arizona, southwestern Colorado, extreme southern Utah and Nevada, and southern California (USFWS 2002). Across this range, it uses a variety of plant species as...

Irrigated Acreage Within the Basin and Range Carbonate-Rock Aquifer System, White Pine County, Nevada, and Adjacent Areas in Nevada and Utah
Toby L. Welborn, Michael T. Moreo
2007, Data Series 273
Accurate delineations of irrigated acreage are needed for the development of water-use estimates and in determining water-budget calculations for the Basin and Range carbonate-rock aquifer system (BARCAS) study. Irrigated acreage is estimated routinely for only a few basins in the study area. Satellite imagery from the Landsat Thematic Mapper and...
Just Add Water and the Colorado River Still Reaches the Sea
Edward P. Glenn, Karl W. Flessa, Michael Cohen, Pamela L. Nagler, Kirsten Rowell, Francisco Zamora-Arroyo
2007, Environmental Management (40) 1-6
A recent article in Environmental Management by All argued that flood flows in North America’s Colorado River do not reach the Gulf of California because they are captured and evaporated in Laguna Salada, a below sea-level lakebed near the mouth of the river. We refute this hypothesis by showing that (1) due...
