The New Millennium Observatory (NeMO) is a seafloor observatory off the coast of Oregon, which studies the relationships between submarine volcanic events and the chemistry and distribution of hydrothermal vents and the biologic communities that depend on them. The research activities at NeMO provide an extraordinary educational opportunity, both from the daily reports from expeditions at sea and ... Full description.

Estuaries have physical traits, and scientists use a variety of measurements such as water depth, salinity, and current speed to describe an estuary. This site describes the various measurements that make up the physical properties of an estuary, using Narragansett Bay as an example. Specific sections of this site focus on water chemistry (temperature, salinity, oxygen, chlorophyll a, and pH), circulation ... Full description.

Ocean chemistry, particularly the carbon cycle, is featured in text and illustrations, with quantitative graphics and a lab demonstration. Graphics include the global carbon cycle from 1980-1989, annual carbon dioxide flux, ocean chlorophyll concentration east of Buenos Aires, and a cartoon showing upwelling of nutrients. Full description.

With three levels to choose from on each page - beginner, intermediate or advanced - this site provides a good introduction to the structure of the ocean. Included are excellent graphics and text about patterns of ocean salinity and temperature with depth, as well as surface currents, deep ocean circulation and even the water cycle. Extensive in-text links provide the means for users to explore the ... Full description.

The Mote Marine Laboratory Phytoplankton Ecology Program focuses on microscopic plants in the oceans, many of which produce harmful toxins. This program addresses phytoplankton behavior, photophysiology and bloom dynamics. This site contains data from investigations, which utilize remote sensing technology for monitoring natural phytoplankton blooms as well as laboratory studies to understand how ... Full description.

This site has been created by the University of Rhode Island's Office of Marine Programs as part of the Narragansett Bay Commission's Environmental Monitoring for Public Access and Community Tracking (EMPACT) project.
