"The Carbon Dioxide Information Analysis Center (CDIAC) is the primary climate-change data and information analysis center of the U.S. Department of Energy (DOE). CDIAC is located at DOE's Oak Ridge National Laboratory (ORNL) and includes the World Data Center for Atmospheric Trace Gases. CDIAC's data holdings include records of the concentrations of carbon dioxide and other radiatively active gases in the atmosphere; the role of the terrestrial biosphere and the oceans in the biogeochemical cycles of greenhouse gases; emissions of carbon dioxide to the atmosphere; long-term climate trends; the effects of elevated carbon dioxide on vegetation; and the vulnerability of coastal areas to rising sea level."

"Carbon Footprint of Nations (CFoN) is an interesting site sponsored by the Industrial Ecology Programme and Department of Energy and Process Engineering, Norwegian University of Science and Technology, in collaboration with the Center for International Climate and Environment Research-Oslo. People certainly hear about carbon footprints and their impact all the time, so this site may interest users concerned about the environment. CFoN clearly states that it provides carbon footprint data not included in the emissions inventories of the UN. The site primarily consists of a blog, the footprint calculator, and an FAQ section. Some blog postings are current, but others are not as up-to-date. Authors who post frequently are listed on the left sidebar, so users can go to all postings from a specific individual. The calculator allows visitors to select a country and view various components of its footprint, e.g., exports, imports, households.

The search function is basic; however, the site map link is right next to the search box, so users most likely will not need to search. The Press link offers access to a few media resources, most of which are European and in various languages. CFoN does not contain an overwhelming amount of information at this time. Although the site is fascinating to look through, it seems to be aimed at serious researchers or those who support the concept of carbon footprints. It worked fine on Internet Explorer 7 and Firefox 3.5.3. Currently, nothing is listed on the Terms and Conditions page. If CFoN becomes a more dynamic site with current postings, it could be of value to a wider audience." from Choice, November 2010.

Delving into the often-confusing world of carbon offset programs and research, CORE compiles data from authoritative governmental bodies and international organizations (e.g., US Environmental Protection Agency, World Bank, UN, and World Wildlife Fund). However, the site states that CORE does not reflect the views of these institutions nor does it obtain any official endorsements from them. An initiative of the Stockholm Environment Institute, CORE provides plenty of data regarding various types of legislation regarding carbon offset programs, both in the US and abroad. The site also includes a decent glossary to help the user navigate through the world of carbon offset and the policies and regulations that define it.
In addition to a general search box, the site offers three categories: Policy, Consumer, and Aviation. The category boxes open on the left side of the home page and contain a number of easily accessible subcategories, which provide the user with clear subject matter. The site contains quite a bit of legislative information as well as some additional information on companies and funds that embrace the carbon offset programs. This site can be described as having a bias toward promoting the subject matter, even though authoritative resources are cited. With that in mind, users should be wary of using this as a single stand-alone reference resource. Appropriate for a broad audience interested in carbon offset issues, CORE should be consulted along with additional resources on the topic. See related, Handbook of Carbon Offset Programs by Anja Kollmuss et al. (CH, Nov'10, 48-1588).

"GeoPlatform - Gulf Response, developed by partnering agencies of the Federal Geographic Data Committee, is a free, interactive tool that provides "near-real time information about the response effort." The site uses a Web-based GIS platform, the Environmental Response Management Application, developed by NOAA and the University of New Hampshire's Coastal Response Research Center. The goal of Gulf Response is to provide a comprehensive source for spill information for responders at federal, state, and local levels as well as the general public and community leaders.

Gulf Response has a clean landing page and includes a video tutorial on how to use the interactive map. The map allows users to place an array of different layers at one time, revealing an evolving picture of the BP Deepwater Horizon oil spill disaster and the ongoing environmental and fisheries response. Layer categories include Resource Management, Bioresources, Sampling, and more. Photos taken by the Shoreline Cleanup Assessment Team can be linked to the map and viewed by selecting the place marks on the map. Additional information can be viewed by selecting the information icon in the upper-left corner and then clicking on that area of the map or the map symbol of interest. Quick clickable tools also help users measure area and distance on the map. Navigation is fairly intuitive. However, one should not select too many layers at one time, because the map can become quite cluttered very quickly. An exceptional resource for anyone interested in learning about the disaster off the Gulf Coast." from Choice, December 2010.

"The University of South Florida Libraries, working in collaboration with other universities, have created a guide to information and data on the BP oil spill in the Gulf of Mexico as well as information on oil spills in other parts of the world.
