"Dredge" is the general usage in America and ,,dredger" is used in most parts of the world.
Dredger is defined as a vessel that is used to excavate the sediments from the seabed with the purpose of:
- Creating new harbors, waterways, bridges, docks
- Maintaining the channels or waterways clean
- Land reclamation
- Mining on the seabed
- Beach nourishment
- Deepening the waterways
- Extracting minerals from underwater deposits
- Removing polluted sediments from rivers, harbors basins
The dredgers can be classified in 2 categories:
- Mechanical Dredgers: involves the use of grab or bucket to loosen the material taken from the seabed
- Hydraulic Dredgers: they are loosening the material through a pipe system connected to a centrifugal pump
- Amphibian Dredgers

What minerals are mined with dredges?

How is sand harvested or extracted?
Sand is typically harvested or extracted from beaches, riverbeds, and quarries using mechanical dredging equipment or suction dredges. In some cases, sand may also be collected manually with shovels and wheelbarrows. It is important to consider the environmental impacts of sand extraction, as it can lead to habitat destruction and erosion.
What is the different between placer mining and quartz mining?
Placer mining is recovering gold dust that has washed into streams and rivers (panning and sluice boxes, as well as dredges today) . Quartz mining involves traditional mining of gold bearing quartz rock, and requires digging,transporting, and crushing the rock to extract the gold.
What tools do marine biologists use?

How old is the oldest animal?
The Giant Tortoise seems to be the animal with the longest life span. For years, the oldest known living animal was a Giant Galapagos Tortoise named Harriet. The giant tortoise was taken from the Galapagos Islands by naturalist Charles Darwin in 1835 as a personal pet during his five-year voyage on the HMS Beagle. On that voyage was a young naval officer, John Clements Wickham. After studying Harriet whilst formulating his theory of evolution, Darwin handed the tortoise on to Wickham when the latter sailed for Brisbane to take up a post as police magistrate. Over the years, the tortoise was carefully tended, and in 1958, was moved to naturalist David Fleay's wildlife park on the Gold Coast. She was moved to Australia Zoo on the Sunshine Coast in 1987 where she enjoyed celebrity status until her death on 23 June 2006.
