Johan Gunnar Andersson in the context of "Geomorphologist"

The Yangshao culture (Chinese: 仰韶文化; pinyin: Yǎngsháo wénhuà) was a Neolithic culture that existed extensively along the middle reaches of the Yellow River in China from around 5000 BC to 3000 BC. The Yangshao culture saw social and technological development in the region, with advancements in agriculture, architecture, and crafts.

The culture is named after the Yangshao site, the first excavated site of this culture, which was discovered in 1921 in the town of Yangshao in western Henan by the Swedish geologist Johan Gunnar Andersson (1874–1960). The culture flourished mainly in Henan, as well as the neighboring provinces of Shaanxi and Shanxi.

Solifluction is a collective name for gradual processes in which a mass moves down a slope ("mass wasting") related to freeze-thaw activity. This is the standard modern meaning of solifluction, which differs from the original meaning given to it by Johan Gunnar Andersson in 1906.

Grytviken (/ˈɡrɪtviːkən/ GRIT-vee-kən Norwegian: [ˈɡɾŷːtviːkn̩]) is a hamlet on South Georgia in the South Atlantic. Formerly a whaling station, it was the largest settlement on the island. Grytviken is located at the head of King Edward Cove within the larger Cumberland East Bay, considered the best harbour on the island. The location's name, meaning "pot bay", was coined in 1902 by the Swedish Antarctic Expedition and documented by the surveyor Johan Gunnar Andersson, after the expedition found old English try pots used to render seal oil at the site. Settlement was re-established on 16 November 1904 by Norwegian Antarctic explorer Carl Anton Larsen on the long-used site of former whaling settlements.

Grytviken is built on a substantial area of sheltered, flat land and has a good supply of fresh water. Although it was the largest settlement on South Georgia, the island's administration was based at the nearby British Antarctic Survey research station at King Edward Point. The whaling station closed in December 1966 when dwindling whale stocks made it financially unviable.

The archaeology of China is researched intensively in the universities of the region and also attracts considerable international interest on account of the region's civilizations. Scholar-officials during the Song dynasty (960–1279) who took up antiquarian pursuits were the first to systematically analyze objects and monuments from China's antiquity.

The application of modern scientific archaeology to Chinese sites began in 1921, when Johan Gunnar Andersson first excavated the Yangshao Village sites in Henan. Andersson believed that prehistoric Chinese culture had a "Western Origin". In fact, most archaeologists at that time believed that all human civilizations, including Chinese, originated in the broader Middle East and then spread to different regions of the world. This statement caused an uproar in China. Chinese archaeologists hope to find evidence to refute this argument, which has led to a series of Chinese-led archaeological projects.
