CO2 from Limestone

[AbbyNormal]

Besides firing it in a kiln or soaking it with acid rain, can some other process cause crushed up limestone, seashells and marls to decompose and produce CO2?

Some thing happening in nature, it sounds dumb but could these substances be baked in the sun and cause some CO2 emissions?

Not really a major source:

More than 98 percent of U.S. carbon dioxide emissions can be traced to the combustion of fossil fuels. Less than 2 percent comes from other industrial sources, including the manufacture of cement and lime. Total estimated emissions increased by 1.5 percent (22 million metric tons of carbon), from 1996 values of 1,479 million metric tons to 1,501 million metric tons of carbon in 1997 (Table 6).(23) Compared with 1990 emissions levels, the increase is 145 million metric tons of carbon or 10.7 percent. U.S. carbon emissions have increased every year since 1991 (Figure 1).

Finding ambient CO2 in what can be described as a suburban area to be higher than an urban area. Soil in the area is marl, a chalky clay. A few constuction sites in the area so lots of exposed marl, no one is running generators.

Trying to look for reasons why the CO2 is higher than in town.

Is there a large body of water nearby?

 

[AbbyNormal]

yes, the Caribbean, 1/2 mile away from leeward, one mile from windward. Actually water 1/2 mile north,1/2 mile west (leeward), and east (windward)

The town I mentioned is right on the leeward coast, maybe 1.5 miles to the windward.

Impossible to be more than 3 miles inland anywhere on island

Some swamp NE as well, maybe its coming from there.

It's also suspected that there are pockets of CO2 under the ground beneath the seas around the Caribean. bimr probabilly didn't take into account your location he quotes "on the average" value's. Anbody brewing up rum around you too?

 

[AbbyNormal]

Negative on the distillation of rum or having a brewery in the neighbourhood. Miles away from the breweries and restaurants with microbreweries. Could be a rasta moonshiner in the bush I suppose

Garbage dump is far away, but swamps and maybe some cattle and chickens not far away.

People expell CO2. Is anybody nearby doing any heavy breathing....?

Could the pictures and other information in this site be of help ?

The difference could be caused by variations in air movement, rather than CO2 sources.

 

[AbbyNormal]

The prevailing winds are out of the ENE here, today it switched out of the SE fairly brisk, CO2 dropped

I looked at a couple of days and it doesn't make sense to me. The area of the US with the highest concentration of fossil fuel burning id nuetral to slightly possitive and other areas with little fossil fuel use are nuetral???? Even the most forrested areas are all nuetral to adding????

dcasto,
That's interesting. Maybe Intelligent design? Putting trees where CO₂ feed content and fossil fuel burners where CO₂ byproduct is low. Le Chatelier would have approved.
