Scientists have been collecting atmospheric CO2 data for many years to monitor changes over time. Which of the following best describes why an island location, such as the Mauna Loa Observatory in Hawaii, is an ideal location to measure global CO2 concentrations? The island is also a dormant volcano, so there will be only anthropogenic atmospheric CO2 measured at the site. A The location is below the inversion layer, making it less prone to local effects from industry and transportation. B The location is far from any continent, providing atmospheric air samples that are less likely to be affected by industry and transportation. C The impact of primary producers in the surrounding Pacific Ocean is negligible, reducing the effect of photosynthesis and respiration on CO2 levels.65

There are different kinds of discoveries by scientist.  The option that best describes why an island location is that;

Carbon dioxide is known as CO 2 for short. It  is a vital trace gas in Earth's atmosphere.

It is also known to be a part of the carbon cycle, where carbon is exchanged between the Earth's oceans, soil, rocks etc.

The correct option is;

B.  The location is far from any continent, providing atmospheric air samples that are less likely to be affected by industry and transportation.

Explanation:

Mauna Loa observatory in Hawaii has the longest running record of air CO₂ content in the world which shows that the CO₂ level is increasing annually as represented in the Keeling curve. The observatory is far remote from industrial centers with a good access to air unadulterated by local CO₂.

The correct option therefore, is that the location is far from any continent, providing atmospheric air samples that are less likely to be affected by industry and transportation.
