Check out this Overview, which shows a fish farming operation in the Saronic Gulf, just off the eastern tip of Greece’s Peloponnese peninsula. Fish farming — or pisciculture — involves raising fish in tanks or enclosures, usually for food. In 2015, Greece had at least 300 of these farms and raised more than 242 million pounds (109 million kg) of fish and mussels.

Sarychev Peak is located on Matua Island in the Kuril Islands of Russia. When the volcano erupted on June 11, 2009, the expulsion of debris caused significant interruption to air traffic between east Asia and North America. The eruption was also so great that astronauts aboard the International Space Station were able to photograph the plumes of ash and smoke rising from its cone, as the force of its shock waves dispersed all clouds covering the area.

Seaweed farms on Nusa Lembongan – a small island located southeast of Bali, Indonesia – have an average harvest of 50,000 pounds per month. Once the seaweed is extracted from the water, it is dried by the sun for 3-7 days, depending on the season.

Seaweed farms surround Sisan Island, off the south coast of South Korea. In “fields” like these, seaweed is often grown on ropes attached to buoys, which hold the crop near the water’s surface. The southern waters of South Korea are ripe with aquaculture operations like these; in fact, this region produces 90% of the nation’s seaweed crop.

Serra de Santa Bárbara is an inactive volcanic peak on the island of Terceira in the Azores, Portugal. At 3,350 feet (1,021 m), it is the highest point on the island.

It consists of 15 vessels that were deliberately sunk in 1963 to form a breakwall for small boats. In addition to providing safe harbor, the wrecks also created a popular dive and snorkel site, attracting a variety of marine life such as wobbegongs, trevally, kingfish, yellowtail and other tropical fish.

Kiribati is a low-lying island nation in the Central Pacific Ocean. The 102,000 residents of Kiribati may be forced to relocate as increased ice melt causes the Pacific Ocean to rise and submerges its islands. Fiji has boldly offered to take in the people of Kiribati if that occurs. Tarawa, an atoll that serves as the capital of the country and is home to half of it’s population, is seen here.

Residential development is seen among tracts of palm trees and other vegetation in the town of Teluk Panglima Garang, Malaysia.

In the center of the desert there are a number of raised, hardened formations that were once the sites of shallow lakes, thousands of years ago.

Peat ponds and polders form a unique landscape in the Twiske, a large recreation area and nature reserve in the northwest of the Netherlands. Polders are low-lying pieces of reclaimed land protected by dikes, and roughly 4,000 of them exist in the Netherlands. Located just north of Amsterdam, the Twiske is home to a wealth of reed and water birds, foxes, ermines, and other wildlife.

Uluru, or Ayers Rock, is a large sandstone formation in the Northern Territory of Australia. The monolith - towering 1141 feet high with an expanse of 2.2 x 1.2 miles - is a sacred site to the Aboriginal people of the area who first settled there 10,000 years ago. While the first Australian tourists arrived at Uluru in 1936, annual visitor numbers rose to over 400,000 by the year 2000. Increased tourism at the site provides regional and national economic benefits, but also creates an ongoing challenge to balance conservation, cultural values, and visitor needs.

Ice melt in the Uummannaq Fjord in Greenland is seen in this Overview. The edges of Greenland’s ice sheet melt every summer; however, because the sheet is steepest at the edge, and flatter towards the middle, the warming of summer exposes a larger area of ice to melting every year. This particular Fjord is the second largest in eastern Greenland behind the Kangertittivaq Fjord.

Vail Ski Resort is located in Eagle County, Colorado, USA. Spanning 5,289 acres, Vail is the third largest single mountain ski resort in the United States and has the fourth largest skiable terrain in North America.

Rising 2,860 m (9,380 ft), Villarrica covers an area of 400 square kilometers. The volcano’s most recent serious eruption was in 2015, which caused the evacuation of thousands of people in nearby communities.

Wadi Rum is a village that has been populated by humans since prehistoric times (8th century BC). Early inhabitants left their mark in the form of rock paintings, which have been thoroughly analyzed by historians.

The Waimakariri River flows for 94 miles (151 km) across the South Island of New Zealand, beginning in the Southern Alps and emptying into the Pacific Ocean.
