WebZinc (Zn) is a key micronutrient for marine phytoplankton, with a global distribution that is similar to silicic acid.The processes that govern this relationship, despite the very … WebThe internal cycling of zinc (Zn) in the ocean has been a longstanding mystery. Particularly puzzling is the strong correlation between Zn and silicate (SiO44−), but not phosphate (PO43−), even though Zn is involved with cell functions that regulate PO43− uptake and are unrelated to SiO44− uptake.
Biogeochemical cycling of zinc and its isotopes in the Southern Ocean
WebJan 15, 2014 · Zinc (Zn) is involved in a number of biological processes in marine micro-organisms (see recent review by Sinoir et al., 2012), such as the important role as a cofactor in the enzyme carbonic anhydrase (Lippard and Berg, 1994) that promotes CO 2 uptake in marine algae ( Morel et al., 1994 ). Web43! with depth. Zn isotopic data beneath 1000m, for the Southern Ocean data presented here as 44! well as published data from the North Atlantic and North Pacific, are strikingly homogeneous, 45! with an average δ66Zn = +0.53±0.14‰ (2SD, 2SE = 0.03, n = 21).

Research efforts in one country alone could not hope to create a comprehensive understanding of trace element cycles in the global ocean. Much new understanding has come, instead, from global programmes that link together the efforts … 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.’. A change in any of these fluxes could have wide-ranging impacts on ecosystems and our climate. alberto intini
