I'm no expert here but sea water is a good insulator of radiation. But once removed the carbon in any substance remains.
Well this is getting in a little deep but Carbon dating, as far as I know it anyways,relies on measuring only the C 14 atoms which remain in the fossil or whatever.
The Earth's atmoshphere is constantly bombarded by cosmic radiationevery day, from memory everything in the universe is subjected toapprox 1/2million cosmic rays every hour. When these rays enter our atmosphere theycollide with otheratomsforming energetic neutrons which in turncollide with nitrogen atoms which change the proton/neutron mix to formasix protoneight neutroncarbon-14 atom.Carbon-14 is radioactive and has a half life decay cycle of around 5 and half thousand years. That is unlike normal Carbon atoms it actually decays and dissipates over timereverting back to it's original atomic structure as the radiation dissipates. This stuff gets into everything by way of the food chains but only remains at a finite level while the living organism is consuming the stuff. When the plant or animal or human dies it stops taking the stuff in and it then starts to dissipate over a very finite time frame. By measuringhow much of it is left in any given fossil it can be determined when the intake stopped, ie death occured hence it's age.
Well that's my brief and general understanding of it anyways and am not aware how oceanic conditions play any role in it.
