Maintenance: Here are some tips Iâve gathered from my own personal use and from some other users for extending the life of these headphones: 1  Donât charge them overnight. If possible, take them off the charger after 2 hours or as soon as theyâre charged. 2  Dry off the earbuds with a towel after each use.
The ocean is thereÂ­fore the greatest of the carbon reservoirs, and essentially determines the atmospheric CO 2 content. The carbon, however, requires centuries to penetrate into the deep ocean, because the mixing of the oceans is a rather slow (Chapter 1) .
Carbon is stored in four main reservoirs. 1  In the atmosphere as CO2 gas. 2  In the hydrosphere (oceans and surface waters) as dissolved CO2. 3  In the biosphere where it occurs as organic compounds in organisms. 4  In the Earth's lithosphere as carbonate minerals, graphite, coal, petroleum.
