Time and Frequency Division at the National Institute of Standards and Technology

The Time and Frequency Division is an operating unit of the Physics Laboratory of the (US) National Institute of Standards and Technology (NIST). It maintains the primary frequency standard for the United States, develops and operates standards of time and frequency and co-ordinates US time and frequency standards with other world standards. The Division's website provides details of its services and research, frequently asked questions, a glossary, a database of full text, time and frequency publications written by NIST personnel since 1914, and links to related websites. Web exhibits include: a history of the measurement of time, a history of calendars, the invention of the quartz watch, the background to daylight saving time, and a short history of NIST time and frequency measurement.

NOAA's Aquarius : world's only undersea research station

Aquarius is an underwater laboratory situated adjacent to deep coral reefs in the Florida Keys National Marine Sanctuary. Scientists live underwater in Aquarius during ten-day missions to study the reef and surrounding ocean. Live webcams of the laboratory are available during missions. There are frequently asked questions; press releases; lessons about buoyancy, pressure, light and coral reefs; and summaries of past missions. Links to other websites about coral reefs and marine biology are listed. Aquarius is owned by the US National Oceanic and Atmospheric Administration (NOAA) and is operated by the NOAA Undersea Research Program's Undersea Research Center at the University of North Carolina Wilmington.

Soil Moisture and Ocean Salinity (SMOS)

The Soil Moisture and Ocean Salinity (SMOS) mission will be ESA's second Earth Explorer in orbit. Launched on 2 November 2009, with a minimum three year duration, SMOS will make global observations of soil moisture over land and of sea-surface salinity over the oceans to improve our understanding of the water cycle. Data from SMOS will be important for weather and climate modelling, water resource management, and agriculture, and will also contribute to the forecasting of hazardous events such as floods. This website from the European Space Agency (ESA) provides information about the mission, the satellite and the launch, together with a brief description of the underlying science. An image gallery, videos, animations and online resources are also provided.

Introduction to geology

This website for this course (12.001 Introduction to Geology, Spring 2008) is made available as part of the MIT OpenCourseWare project. It includes a syllabus, readings, lecture notes, laboratory practicals, assignments and handouts. The course introduces "major minerals and rock types, rock-forming processes, and time scales; temperatures, pressures, compositions, structure of the Earth, and measurement techniques; geologic structures and relationships observable in the field; sediment movement and landform development by moving water, wind, and ice; crustal processes and planetary evolution in terms of global plate tectonics with an emphasis on ductile and brittle processes." The notes are available as PDF files.

Genetics Selection Evolution

The Genetics Selection Evolution journal was created by the French National Institute for Agricultural Research (INRA) in 1960, and this site offers scientists and others online access to its contents. The primary focus of the journal is to present "original research on all aspects of genetics and selection in both farm and experimental animals." The journal is part of the BioMedCentral network of open access journals, and the homepage offers easy access to its latest peer-reviewed articles. Visitors to the journal's homepage can view a list of its current editorial board members, sign up to receive the journal's RSS feed, and also review manuscript submission guidelines. A sidebar on the left-hand side of the homepage includes a list of the most accessed articles, promotional devices (such as posters and leaflets), and a FAQ section.

BioSciEdNet

This impressive portal (referred to in the shorthand as "BEN"), was created by the National Science Digital Library (NSDL) in order to bring high-quality educational resources to science educators everywhere. The entire project is managed by the American Association for the Advancement of Science (AAAS), and the resources here total over 14,000, and they cover 77
discrete biological sciences topics. First-time visitors to the site will note that will they are not required to register to access these resources, however they may wish to do so in order to maintain a thorough list of the resources they find most useful here. The homepage is simple and to the point, and it features a "New Resources" area, and a collection of browsing options that allow users to pick out resources by type, audience, or subject. Persons who haven't used BEN before may wish to look at the "Using BEN" area for a bit of guidance.
