The bottom of the ocean is a very important place for marine life.Just about 90% of all marine species live at least part of their life associated with the bottom. We call this mode of life 'benthic.' These species can be found in the intertidal, shelf, bathyal, abyssal, and hadal zones.Some species even live under the surface of the bottom of the ocean (called infauna).The bottom of the ocean is a major area of decomposition where organic material is recycled (cells are broken down and nutrients are released by bacteria and fungi).ome species even live under the surface of the bottom of the ocean (called infauna).

Including the costs of refueling aircraft carriers and other items, such as outfitting new ships, raises the overall average cost of the Navyâs plan to $20.7 billion per year, CBO estimates. That figure is slightly less than CBOâs estimate of the average annual cost of the Navyâs 2014 plan.CBOâs estimate of the cost of new-ship construction in the Navyâs 2015 shipbuilding plan is $66 billion, or 13 percent, higher over the next 30 years than the Navyâs estimate.eport. CBO estimates that the cost of the Navyâs 2015 shipbuilding planâan average of about $21 billion per year (adjusted for inflation) over 30 yearsâwould be one-third higher than the funding that the Navy has received in recent decades.
