[1] The canyon is believed to have formed through mass failures, and subsequently evolved through underwater erosion.
[2] Continental shelves off major river deltas and estuaries act as interfaces between terrestrial environments and depositional regimes in the deep sea.
[3] The Amazon River is 6,770 km long and with its numerous tributaries drains a watershed of 7,050,000 km2.
[8] As a result, this actually helped develop the Amazon fan lobes and overall structure.
[9] One of the conclusions of this study stated that organic carbon buildup on the Amazon deep sea fan is controlled by changes in glacioeustatic sea-levels.
