Letter to Oceanus

What I was looking for is research into how Galactic Cosmic Rays may effect the growth and migration of heterotrophic marine bacteria such as Roseobacter class. I have a hunch that if GCR rate is high, this will have a negative effect on the bacteria causing them to migrate away from the surface of the Ocean into the depths. At the same time the Cyanobacteria protected within the calcium shells of the diatoms will not have its DMS products stolen by the bacteria and will reproduce at a much faster rate resulting in blooms. Also the Zooplankton will migrate away from a higher GCR rate so there will be less feeding on Phytoplankton. Altogether my theory states that a higher GCR will result in Phytoplankton blooms and a Cooler planet as a result. But I can not verify this theory without field work that would need to be done, such as quantifying populations of marine bacteria at different times of the day, diurnal migrations, comparisons with populations for different rates of GCR coinciding with Solar activity. I have not been able to find any scientific work done on the GCR effects on bacteria growth. It makes sense that high frequency waves will cause mutations and cell damage to bacteria outside of a calcium shell. I believe this is the key to Climate on planet Earth.
