In August 1908, a white mob attacked Springfield, Illinois’s Black community, destroying homes and businesses and lynching two Black men. National outrage over the violence helped spur the movement that created the NAACP the following year.

The Caribbean Coral Reef Ecosystems (CCRE) program began with a collaborative field project conceived by six National Museum of Natural History scientists during the early 1970s. The scientists interests included a range of disciplines central to reef ecology, including: invertebrate and vertebrate zoology, botany, carbonate geology, and paleobiology. The primary work site is the Carrie Bow Marine Field Station, a research station at Carrie Bow Caye (16°48′9″N 88°4′55″W) on the Meso-American Barrier Reef in Belize. The program is an extended duration study of coral reefs, mangroves, sea grass meadows, and the sandy bottoms. It has been a functioning research program since the early 1970s when it was called the Investigations of Marine Shallow-Water Ecosystems (IMSWE).

The Smithsonian Marine Station at Fort Pierce is a research center that specializes in Floridian marine ecosystems and lifeforms. The research is focused mostly on the Indian River Lagoon and also on the offshore waters of Florida's central and east coast. The first director of the station was Mary Rice, who was also instrumental in its founding. The station is a part of the National Museum of Natural History, which is part of the Smithsonian Institution of Washington, D.C. Its purpose is to be a field station which will draw scientists and students from the Smithsonian and other institutions from around the world, in which they will investigate animals, plants, and physical processes of oceans and rivers. The information obtained at the station will be published in forms and scientific journals. It also provides administrative and logistical management of the Caribbean Coral Reef Ecosystems Program, that is based at the Carrie Bow Cay Field Station. Both stations are important to the Smithsonian Marine Science Network.
An artificial reef (AR) is a human-created freshwater or marine benthic structure. Typically built in areas with a generally featureless bottom to promote marine life, it may be intended to control erosion, protect coastal areas, block ship passage, block the use of trawling nets, support reef restoration, improve aquaculture, or enhance scuba diving and surfing. Early artificial reefs were built by the Persians and the Romans. An opportunity artificial reef is built from objects that were intended for other purposes, such as sinking oil rigs (through the Rigs-to-Reefs program), scuttling ships, or by deploying rubble or construction debris. Shipwrecks may become artificial reefs when preserved on the seafloor. A conventional artificial reef uses materials such as concrete, which can be molded into specialized forms (e.g. reef balls). Green artificial reefs incorporate renewable and organic materials such as vegetable fibres and seashells to improve sustainability and reduce energy consumption, pollution, and greenhouse gas emissions. In some cases, artificial reefs have been developed as artworks. Artificial reefs generally provide hard surfaces where algae and invertebrates such as barnacles, corals, and oysters attach and spaces where different sizes of fishes can hide. The accumulation of attached marine life in turn provides intricate structures and food for assemblages of fish. The ecological impact of an artificial reef depends on multiple factors including where it is situated, how it is constructed, and the ages and types of species involved. While the artificial reefs allow for coral growth, it changes the ecosystem as the relative growth for different species is not always the same. Studies have found that macroalgal, cyanobacterial groups, and coral that are fast growing, grow in artificial reefs at different rates than they would grow in natural reefs. Considerable research is being done into construction methods and the effects of artificial reefs. Many of the materials used early on are now considered undesirable. A 2001 literature review suggested that about half of the reefs studied met their objectives. Long-term planning and ongoing management were identified as essential factors in success. A more recent analysis of reefs world wide between 1990 and 2020 concludes that artificial reefs can be useful tools for restoring marine ecosystems if they are strategically designed to suit their specific location and its resource needs.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
