            "description": "This animation shows the population density of the world in the years 1990, 1995, 2000, as well as a population density estimated for the year 2015.  These figures have been adjusted to match United Nations totals.  The most dramatic differences in population are not readily visible in this animation because they are located in cities.  The maximum population density in 1990 was about 79,000 people per square kilometer, while the estimated maximum population density in 2015 will be about 236,000 people per square kilometer.  Developing areas in Africa, Latin America, and Asia change the most visibly. || ",

            "title": "Mississippi Dead Zone",
            "description": "Recent reports indicate that the large region of low oxygen water often referred to as the 'Dead Zone' has spread across nearly 5,800 square miles of the Gulf of Mexico again in what appears to be an annual event. NASA satellites monitor the health of the oceans and spots the conditions that lead to a dead zone. These images show how ocean color changes from winter to summer in the Gulf of Mexico. Summertime satellite observations of ocean color from MODIS Aqua show highly turbid waters which may include large blooms of phytoplankton extending from the mouth of the Mississippi River all the way to the Texas coast. When these blooms die and sink to the bottom, bacterial decomposition strips oxygen from the surrounding water, creating an environment very difficult for marine life to survive in. Reds and oranges represent high concentrations of phytoplankton and river sediment. The National Oceanic and Atmospheric Administration (NOAA) ships measured low oxygen water in the same location as the highly turbid water in the satellite images. Most studies indicate that fertilizers and runoff from human sources is one of the major stresses impacting coastal ecosystems. In the third image using NOAA data, reds and oranges represent low oxygen concentrations. || ",

            "title": "Urbanization around the Pearl River Estuary in China from 1973 through 2001 (WMS)",
            "description": "The region around the Pearl River Estuary in southern China experienced rapid urban growth in the 1980s and 1990s. This growth was spurred by the establishment of special government economic zones, particularly in Shenzhen, just to the east of the estuary. Urban areas increased by more than 300% between 1988 and 1996. This growth can be directly assessed by remote sensing measurements from space, particularly by comparing images from the Landsat sensors for the last thirty years. This animation shows nine such images in sequence, from the years 1973, 1975, 1977, 1979, 1988, 1992, 1995, 2000, and 2001. || ",
