For example, in Fedex Corp. v. United States, [10] the taxpayer performed repairs upon jet engines by removing them from the airplane and then having parts replaced. The taxpayer argued that these expenses were deductible, but the IRS stated that the costs should be capitalized.
Water is the medium of the oceans, the medium which carries all the substances and elements involved in the marine biogeochemical cycles. Water as found in nature almost always includes dissolved substances, so water has been described as the "universal solvent" for its ability to dissolve so many substances.
The ocean is currently suffering from the impacts of human damage including pollution, acidification, species loss, and more. This could prove particularly catastrophic given that the ocean takes up the largest part of the planet and serves as the home to many organisms, including the algae that provides around half of the oxygen on Earth.

Biological oceanography is the study of how organisms affect and are affected by the physics, chemistry, and geology of the oceanographic system.Biological oceanography may also be referred to as ocean ecology, in which the root word of ecology is Oikos (oικoσ), meaning ‘house’ or ‘habitat’ in Greek.
Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...
Another example among spiders is the species Moggridgea rainbowi, the only Australian member of a genus otherwise endemic to Africa, with a divergence date of 2 to 16 Ma ago. [ 20 ] However, oceanic dispersal of terrestrial species may not always take the form of rafting; in some cases, swimming or simply floating may suffice.
[2] [8] In groundwater wells, biofouling buildup can limit recovery flow rates, as is the case in the exterior and interior of ocean-laying pipes where fouling is often removed with a tube cleaning process. Besides interfering with mechanisms, biofouling also occurs on the surfaces of living marine organisms, when it is known as epibiosis.
Ocean Conservancy and its International Coastal Cleanup is an example of a public-facing campaign that aims to increase participation in conservation efforts among every day civilians. On a predetermined date every year, Ocean Conservancy promotes The International Coastal Cleanup to rally communities to volunteer to collect trash from the ...
