Atmospheric scientist have been observing carbon dioxide levels over several years and in different areas. They want to know how much concentrations of CO2 have been increasing and where it is coming from. They also want to know which of Earth's features act as a carbon sinks. A carbon sink involves the removal of carbon from the atmosphere  and storage of carbon somewhere else. Known carbon sinks include the ocean and forests. The scientist use a number of sampling methods.   What is the best sampling plan for determining how well ocean functions as a carbon sink?  1. Daily samples for a year in many places over land and ocean. 2. Hourly samples for one day in many places over land and ocean.   3. Daily samples for a year above a likely spot in the ocean.   4. Hourly samples for one day above a likely spot in the ocean.
