North Atlantic Deep Water be detected by its high salinity, high oxygen content, nutrient minima, high C/C, and chlorofluorocarbons (CFCs). CFCs are anthropogenic substances that enter the surface of the ocean from gas exchange with the atmosphere. This distinct composition allows its path to be traced as it mixes with Circumpolar Deep Water (CDW), which in turn fills the deep Indian Ocean and part of the South Pacific. NADW and its formation is essential to the Atlantic Meridional Overturning Circulation (AMOC), which is responsible for transporting large amounts of water, heat, salt, carbon, nutrients and other substances from the Tropical Atlantic to the Mid
Sirena Deep Philippine legends of the sirenas, which are a mix of mermaids and sirens. The new name will now appear on geologic and bathymetric maps. Sirena Deep The Sirena Deep was discovered in 1997 by a team of scientists from Hawaii. Its depth (10,732 metres) is thought to be second or third only to the Challenger Deep and possibly Horizon Deep, currently the deepest known places in the ocean. It lies along the Mariana Trench, 200 kilometers to the east of the Challenger Deep and 145 km south of Guam. The Sirena Deep was most probably formed, not through transform fault
