• "Although the effects of UV-B radiation are strongly species-specific, marine bacterioplankton and phytoplankton can be negatively affected [36]."
• "In the northern Bering and southern Chukchi Seas, primary production occurs over a shallow shelf (50 to 200 m) and as the zooplankton and bacterioplankton cannot fully deplete this carbon source, it is either transferred to the benthos or advected downstream [17]."
• "While plankton are found in the greatest abundance in surface waters, in areas that are too deep for primary production to occur, zooplankton and bacterioplankton can make use of organic material that sinks down from the surface waters above."
