Tritium and radiocarbon dating of Canada Basin deep waters

Article Abstract:

Tritium radiocarbon dating calculations puts the Canada Basin's age at 500 years old. This part of the Arctic Ocean actually contains two disconnected basins. It is difficult to determine where elements such as carbon are produced and introduced into these deep waters.

Neptune's deep chemistry

Article Abstract:

Astrophysical research findings suggest some of the planet Neptune's atmosphere may have come from below a methane-rich ocean which might cover the planet. Methane in Neptune's atmosphere may be produced by a quenched reaction inside the planet.
