Intermediate trophic level (ITL) organisms can interfere with navigation and surveillance equipment, making it difficult to carry out some operations efficiently. To address the issue, the Navy started researching this marine life last year. Naval Research Laboratory (NRL) oceanographer Brad Penta led the research project

Microplastics Accumulate in Deep-Sea Life Hotspots

Research published this month reveals that microplastics often accumulate on the deep sea floor in the same place as diverse and dense marine life communities. This is because the same submarine sediment flows that transfer the oxygen and nutrients needed to sustain life, also transport microplastics from urban rivers to the deep-sea floor via pathways such as submarine canyons.  The findings result
