Pandoravirus sediments. Pandoraviruses, like other marine viruses, prey on plankton, which are organisms that live in the water column and form the basis of the food chain for other marine species. More study and research needs to be done in order to confirm the prevalence of Pandoraviruses in different environments. Currently, not much is known about their role in marine ecosystems. Pandoraviruses do have approximately 93% of their genes that are unidentifiable with any other microbes, suggesting they may belong to an as of yet undescribed "fourth domain" aside from Bacteria, Archaea, and Eukaryotes. Viruses as a whole are not popularly
Arctic National Wildlife Refuge Wildlife Refuge is the only refuge that regularly dens polar bears in that local region, and contains the most consistent amount polar bears in the area. The Arctic basin is the shallowest ocean basin on Earth. It is the least salty, because of low evaporation and large current of freshwater from rivers and glaciers. River mouths and calving glaciers, are continually moving ocean currents contribute to a unique marine ecosystem in the Arctic. The cold, circulating water is rich in minerals, as well as the microscopic organisms (such as phytoplankton and algae) that need them to grow. Marine animals thrive
