Tin in oceans



High concentrations of tin in the North Atlantic, discovered by two Florida State University oceanographers, have been linked with waste incineration and the burning of fossil fuels in North America and northern Europe. The oceanographers say that the tin in the North Atlantic was transported there primarily through the atmosphere.

In what the National Science Foundation (NSF) is calling the first systematic study of tin in the oceans, Meinrat O. Andreae, associate professor of oceanography, and James T. Byrd, an oceanography graduate student, found that concentrations of tin are up to 20 times greater in the North Atlantic Ocean than they are in the uncontaminated equatorial and tropical Pacific Ocean. NSF funded the research.
