The internal cycling of zinc in the ocean

WebThe removal of zinc from solution via adsorption processes is an important process in natural waters (CCREM 1991). Zinc can sorb to iron, aluminium and manganese (oxy)hydroxides (Lee 1975, Dzombak & Morel 1990), clay minerals (USEPA 1979d) and colloidal organic matter (Tessier et al. 1996).

The biogeochemical cycling of … Zinc-containing minerals in the Earth's crust exist primarily as sulfides, such as sphalerite and wurtzite, and carbonates such as smithsonite. Zinc minerals enter the terrestrial environment through weathering and human activities. Zinc is used by plants and other organisms, and then enters aquatic systems where it either settles into sediments or eventually enter the oceans. Zinc is a marine micronutrient that tends to be in higher concentration in the deep ocean and is tr… WebThe ocean carbon cycle. Carbon, a building block of life, is constantly moving through different environmental compartments such as biota, the atmosphere, the ocean, soil and sediment, as part of what is called ‘the global carbon cycle.’.
