Table 2. Log-log slopes and fits between viral and prokaryotic abundance in the epipelagic, mesopelagic, and bathypelagic layers in the three different oceans and in all the subtropical ocean and power-law log-log slopes and fits of the relationship between depth and viral abundance in the three different oceans and in all the tropical and subtropical oceans.
