Eutrophication is a big word that describes a big problem in the nation's estuaries. Harmful algal blooms, dead zones, and fish kills are the results of a process called eutrophication — which occurs when the environment becomes enriched with nutrients, increasing the amount of plant and algae growth to estuaries and coastal waters.

Out to sea. Current deep-sea-mining proposals are expected to generate two types of sediment plumes in the ocean: "collector plumes" that vehicles generate on the seafloor as they drive around collecting nodules 4,500 meters below the surface; and possibly "midwater plumes" that are discharged through pipes that descend 1,000 meters or more into the ocean's aphotic zone, where ...

There are four main filtration options for dewatering tailings after thickening but prior to disposal: vacuum filters, centrifuges, belt presses, and filter presses. For every solution, it is recommended the filter feed slurry be thickened prior to filtration as this can substantially reduce capital and operating costs of the filtration operation.

These patches are formed by large, rotating ocean currents called gyres that pull debris into one location, often to the gyre's center. There are five gyres in the ocean: one in the Indian Ocean, two in the Atlantic Ocean, and two in the Pacific Ocean. Garbage patches of varying sizes are located in each gyre.

Pliant also proposes sending the nodules to the ocean's surface in packets using buoyancy, which it anticipates would be less energy-intensive than a riser system. "Each packet of nodules will require a significant initial energy input, but once it has positive buoyancy, it's an energy-free ride all the way up to the surface," Filardo explains.

Cleaning up rivers can help elevate the toxic materials that are poisoning the water. The clean up can be in the form of directly clearing the waste from the water. Another way to help clean up is by picking up the slightest hint of litter around the river before more trash accumulate and float in the river water. 4. Avoid Disposing Oil into Sinks

It is possible to estimate primary oceanic production from such chlorophyll concentration observations, leading to an overall figure of 50 GtC per year, or about 50% of terrestrial production. It is remarkable that the carbon stored in marine life is nearly 200 times lower than that in terrestrial environments (3 GtC versus 500 GtC).

Some mining techniques — like in-situ leaching, which uses acid and water to remove minerals from a site without significantly disturbing the surface — have much less environmental impact. In-situ mining techniques can use less water than open-pit mining and underground mining, and also reduce the risk of releasing ore dust into the atmosphere.

Seabed Mining (SBM) is a growing industrial field that involves extracting submerged minerals and deposits from the sea floor. To date, mining for sand, tin and diamonds has been generally limited to shallow coastal waters. Seabed Mining (SBM) should be distinguished from Deep Sea Mining (DSM) that occurs at a depth of 200 meters and greater.
