Global Seafloor topography from Satellite Altimetry
Maps of seafloor elevation based on data collected by satellites. The satellite can't "see" the bottom of the ocean, instead it measures the elevation of the ocean and infers the shape of the seafloor. It seems like magic, but it's really science. See how cleverly it's done on the methods page.

About Coral Reefs
"Coral reefs are complex, biologically diverse ecosystems. Countless studies, books and papers have been devoted to exploring and understanding the nature of these unique marine environments. These four essays discuss some of the most important aspects of coral reefs. Many of their physical and biological characteristics are discussed in detail. Coral reef threats, both natural and anthropogenic, also are explored."

Coral Reefs
"... two sections devoted to learning about coral reefs: an online tutorial, and an educational roadmap to resources. The Coral Tutorial is an overview of the biology of and threats to coral reefs. The tutorial is rich in substance and is presented in easy-to-understand language. It is made up of 11 "chapters" or pages (plus a reference page) that can be read in sequence by clicking on the arrows at the top or bottom of each chapter page. The tutorial includes many illustrative and interactive graphics to visually enhance the learning process. The Roadmap to Resources complements the information highlighted in the tutorial.

"There has been significant bleaching of hard and soft corals in widely separate parts of the world from mid-1997 to the last months of 1998. Much of this bleaching coincided with a large El Nino event, immediately switching over to a strong La Nina. Some of the reports by experienced observers are of unprecedented bleaching in places as widespread as (from west to east) the Middle East, East Africa, the Indian Ocean, South, Southeast and East Asia, far West and far East Pacific, the Caribbean and Atlantic Ocean."

"The IUCN Red List of Threatened Species provides taxonomic, conservation status and distribution information on taxa that have been evaluated using the IUCN Red List Categories and Criteria. This system is designed to determine the relative risk of extinction, and the main purpose of the IUCN Red List is to catalogue and highlight those taxa that are facing a higher risk of global extinction (i.e. those listed as Critically Endangered, Endangered and Vulnerable). The IUCN Red List also includes information on taxa that are categorized as Extinct or Extinct in the Wild; on taxa that cannot be evaluated because of insufficient information (i.e. are Data Deficient); and on taxa that are either close to meeting the threatened thresholds or that would be threatened were it not for an ongoing taxon-specific conservation programme (i.e. Near Threatened)."

Specifically, the synthesis of information will support the definition of science-based targets for avoiding species extinctions, protecting critical areas within the hotspots, and developing conservation strategies that will enable the persistence of biodiversity over time.

USDA PLANTS Database
The PLANTS Database is a single source of standardized information about plants. This database focuses on vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories. The PLANTS Database includes names, checklists, automated tools, identification information, species abstracts, distributional data, crop information, plant symbols, plant growth data, plant materials information, plant links, references, and other plant information. PLANTS reduces costs by minimizing duplication and making information exchange possible across agencies and disciplines.
