MIT OpenCourseWare: Introduction to Geology

If you are having difficulty remembering the details of the Earth's geological structure or the nature of major minerals and rock types, you can consult this excellent introductory course offered as part of MIT's OpenCourseWare initiative. The materials are drawn from Professor Lindy Elkins-Tanton's Spring 2008 "Introduction to Geology" course, and they include a syllabus, a course calendar, readings, lecture notes, and assignments. The course is designed for undergraduates, though anyone can benefit from examining the materials. Visitors can make their way through lecture notes that cover metamorphic rocks, rock deformation, earthquakes, and the formation of continents. The site also contains some great handouts which cover time scales, New England geology, and oxygen isotopes. Finally, visitors can also send feedback about the course.

Measurements of atmospheric composition in the ultraviolet and visible

This site, offered by the US National Aeronautics and Space Administration (NASA), provides “the results and ongoing data studies for the study of ozone and other gases, aerosols, radiances, and ultraviolet radiation, and what has been learned about atmospheric pollution and air quality from the international science missions making these measurements.” More specifically users can access tropospheric composition data, obtained using ultraviolet and visible spectroscopy, for total ozone concentrations, aerosol index, radiative cloud fraction, surface UV flux, cloud fraction, as well as the atmospheric concentrations of pollutant gases such as sulphur dioxide, nitrogen dioxide, formaldehyde, bromine monoxide and chlorine dioxide. Active dates for the available atmospheric composition records depend on the instrument used to collect the data, with some datasets dating back to 1978. The site also provides information about the specific instruments used to collect these measurements and documentation on how to download and interpret the available datasets.

American Society of Limnology and Oceanography

If you've ever wondered about the fields of limnology or oceanography, you
need look no further than the homepage of the American Society of Limnology
and Oceanography (ASLO). On their site, visitors can learn about their
professional activities, which include international symposia, conferences,
and their scholarly journals. In their "About ASLO" area, visitors can learn
about the discipline and read up on ASLO history. Most visitors will get the
most use out of the "Programs" area. This section of the site includes an
image library, articles about ethical considerations in the field, resources
for early career scientists, and programs for current students. The image
library is a highlight here, and it includes well over 2000 images submitted

Scirus reviewed - Péter's Digital Reference Shelf

Scirus stands out among the few multidisciplinary science-oriented databases that are freely available on the Web by virtue of its capable and intelligent software.... and deep indexing and searching of more than 53.5 million scholarly and/or professional documents.....
Scirus has been progressing and expanding steadily since its debut in 2001. With the significant additions of tens of millions of high quality scholarly papers, it is an outstanding source even for users whose libraries don’t have subscription to many digital journal packages. It is a very good free federated search engine for those who are looking for scholarly publications, and can live with finding a few far less than scholarly pages in the process.

Database Documents Names for More Than 150,000 Diptera Species

Distinguishing between insect pests and partners starts with an ironclad identification. So Agricultural Research Service (ARS) entomologist Chris Thompson headed up efforts to accurately identify and name almost 157,000 flies, gnats, maggots, midges, mosquitoes and related species in the order Diptera.

Diptera is one of the four largest groups of living organisms on Earth, and its members are critical components in virtually all non-marine ecosystems. Carl Linnaeus, who devised the scientific classification system still in use today, compiled the first index of Diptera species names in 1758. But even though an average of 800 new Diptera names are proposed every year, the nomenclature has not been comprehensively updated since 1805.

The group assembled the tenth edition of the Biosystematic Database of World Diptera (BDWD). This massive index contains nomenclature data for 156,599 living and extinct Diptera species in 154 families and 11,671 genera—around 10 percent of the known biodiversity in the world today.

The BDWD, which is available at www.diptera.org, has two components. The Nomenclator allows users to check names, confirm species status, and obtain information about type, family classification and sources for all names in the collection. The Species database is being designed to answer queries about different species, including their distribution, biological associates and economic importance.

Microbial Life-Educational Resources

The Marine Biology Laboratory of Woods Hole, Massachusetts and Montana State University re the collaborators on this easily navigable website of educational resources about microbial life. The goal of the site is to provide expert information about microorganisms for K-12 classrooms, university educators, and the general public. They effectively accomplish their goal here, with a host of resources, in formats appropriate for different knowledge levels, in a well-organized manner. For all of the topics covered, three levels of information are provided. Resources such as newspapers, websites, and magazine articles are provided for general learners; journal articles and academic reviews are provided for advanced learners; and activities, assignments, and readings are provided for educators. Interestingly, one of the activities found in the "Teaching
Methods" tab on the left side of the homepage, is how to use the Socratic Method with students, with question suggestions, rules of participation, and what to expect from the students. An interesting part of the website is its focus on the microorganisms that live in extreme nvironments. Visitors can learn about the many types of extremes environments, the extremophiles, and how to teach about extreme environments in K-12 classrooms, by clicking on the "Extreme Environments" tab on the left side of the homepage. The photos of the extreme environments resemble abstract art with their close ups of the microorganisms in their environment. By clicking on the "Online Resources" tab on the left hand side of the homepage, visitors will be taken to a virtual index of their resources, where they can also narrow their view
by resource type, subject, environment type, and grade-level. Each category that can be used to narrow results also shows how many entries are available for that category. [KMG]
