Overview
The Maxim iButton temperature logger is a self-contained, self-powered, and field-rugged package that measures just over 0.5 inches in diameter. Based on iButton technology, the logger consists of a computer chip, temperature sensor, and battery enclosed in a 16mm thick stainless steel can.
Mechanics
The small size of the temperature data logger allows it to be securely hidden in important monitoring areas. Each iButton has a unique ID to ensure traceability. The logger uses its stainless steel can as an electronic communications interface. By simply touching the logger to the DS1402 USB reader, the user can set up deployments, upload data, and view the logger status using Maxim OneWireViewer Software or 3rd party programs.
Design
iButton loggers are rugged enough to withstand environmental hazards, indoors or outdoors. The durable stainless steel package is resistant to dust and moisture. A full line of accessories are available for mounting and deploying the loggers including adhesive pads, keychain fobs, and underwater housings.
Applications
Common applications include water temperature profiling, cargo transportation monitoring, ambient air monitoring, animal roosting behavior studies, new product research & development, wide-area temperature networks and much more.

Washington and Jefferson College students create semester-long field studies
When late-winter snow falls on a nature preserve near Washington, Pa., melted divots surround Eastern skunk cabbages. 
 The cabbage’s capability to generate heat is one of many topics students in a Washington and Jefferson College ecology course investigate during a single semester of classes. 
 The ecology class starts with a trip to the Abernathy Field Station, a natural area where all students and faculty can contemplate science, literature, art or life itself. 
 Students in the school’s ecology capstone each choose a topic to study. At the end of the semester, they draw their conclusions and share findings with students, professors and the public at a student research symposium.

Planning stream restorations is becoming more important as the number of projects increases nationwide, in efforts to enhance water quality and habitat health of surrounding areas. 
 
Researchers at the State University of New York College of Environmental Science and Forestry (SUNY ESF) and Syracuse University led a study of two streams in upstate New York that had undergone restoration. They found restoration work created large areas of "transient storage" where water is temporarily retained behind restoration structures that enhanced downwelling to rates not observed in reference reaches. In natural streams, these transient storage zones are known to host biological and chemical processes that allow the stream to clean itself.
Read MoreWisconsin trout stream temperature study shows benefits of shade trees
When settlers in Central Wisconsin cleared the land of hardwood forests, the loss of shade warmed the some of region's stream temperatures beyond what cold-loving species like brook trout could take. Recently published results of a data collection and modeling effort there shows managers how much stream habitat would still be suitable for trout if trees still lined the banks. 
 
The link between shade from streamside trees and water temperatures is well established, said Ben Cross, study author and doctoral student in Washington State University's School of the Environment. So is the link between stream temperatures and brook trout distribution. 
 
Cross and his colleagues wanted to take the link a step farther and calculate just how much trees helped cool streams.
