Ecosystems

The term El Niño (Spanish for 'the Christ Child') refers to a warm ocean current that typically appears around Christmas-time and lasts for several months, but may persist into May or June. The warm current influences storm patterns around the globe. As...
Land use change is perhaps the most observable of all environmental changes. Because land use change is connected to a wide range of societal and environmental processes, a robust body of land use change research helps us understand an extensive variety...
South Florida is a unique but endangered ecosystem. Prior to significant human activity in the area (mid-1800's), south Florida constituted one of the largest wetlands in the continental United States. The Everglades, referred to by Marjory Stoneman...
Scientists travel to Florida several times a year to collect samples. In the Everglades, peat cores are taken and modern pollen traps are set throughout the area. The cores are cut into 2cm pieces. Each piece is treated with strong chemicals in a lab to...
Scientists studying the south Florida ecosystem have learned that invading cattail plants increased in number and are slowly displacing the native sawgrass communities along the margins of the canals. This may be due to increased nutrients entering the...
A number of photo galleries, including nature and project photo galleries, are available on the SOFIA website. Take a visual tour of south Florida, see scientists taking core samples, scientists working in the field, Everglades gage site photos,...
Using the EDEN website, you can monitor water levels at 100 marsh water-level gages and 394 tree islands in different locations in south Florida. The EDEN website also produces automated, daily-updated monthly percentiles plots of water level so that...
Data for rainfall, ET, and water-level height at gages can be explored, searched, and downloaded using a new online tool called Explore and View EDEN (EVE). Rainfall and evapotranspiration (ET) are important components of the water cycle, particularly in...
Scientists have gathered and studied data in support of Everglades Restoration covering a variety of topics: biology, chemistry, ecology, geology, hydrology, modeling, and digital data sets for geographic information systems (GIS). Datasets, along with...
By looking at core samples, which are vertical cylindrical samples taken out of the ground, scientists are able to see what past conditions were like. In south Florida, shallow sediment cores were collected within the bays, and the faunal and floral...
