Abstract

By the data of the Jiaozhou Bay (Shandong, China) from May 1991 to February 1994 and those of Hawaii from March 1958 to December 2007, with the statistics and differential equations analyzed were the seasonal variations in atmospheric carbon in the Northern Pacific Ocean (NPO), and in phytoplankton primary production in the Jiaozhou Bay, and its relationship in the study regions. The study unveiled that the seasonal change of the atmosphere carbon and primary production has the same period. In a year, the primary production and atmosphere carbon had two balance points: the points of May and October, during which the amount of atmosphere carbon decreased. As phytoplankton absorbed atmosphere carbon, When primary production in spring > 181.60 (mg/m2 d) ~ 297.57 (mg/m2 d) or 754.74 (mg/m2 d) ~ 1160.13 (mg/m2 d) in Sept. or 552.94 (mg/m2 d) ~ 890.69 (mg/m2 d) in Oct, the atmosphere carbon fell. Therefore, it is considered that from May to Oct. every year, phytoplankton growing in bloom controlled the increase of atmosphere carbon. From Dec. to next April, human discharging the carbon controlled its increase. The results supported the viewpoint shown by Yang (2010): the variation in atmospheric carbon was determined by human discharge and phytoplankton growth. The result in this paper showed that the earth ecosystem kept the percentage of the decrease amount of atmospheric carbon to its amount taken up by phytoplankton as 1.60% ~ 0.34% and maintained the dynamic balance of carbon by emitted by human being into the atmosphere and absorption of phytoplankton to atmosphere carbon. Therefore, the ecosystem was considered to be of the great power and accuracy.

Highlights

Since industry revolution, the atmosphere carbon concentration rises obviously every year, which leads to global warming and affects the climate and environment of the earth. 95% of the carbon in ecological circle lies in ocean, which is the largest carbon store of the earth
This paper showed the seasonal change of phytoplankton primary production in the Jiaozhou Bay from 1992 to 1994, that of atmospheric carbon from 1958 to 2007 in Mauna Loa in NOAA Earth System Research laboratory in Hawaii that of the atmosphere in the North Pacific ocean
The atmosphere carbon began to fall at the one balance point of May till it finished at the other balance point of October

Summary

Introduction

The atmosphere carbon concentration rises obviously every year, which leads to global warming and affects the climate and environment of the earth. 95% of the carbon in ecological circle lies in ocean, which is the largest carbon store of the earth. 95% of the carbon in ecological circle lies in ocean, which is the largest carbon store of the earth. It contains the CO2 from atmosphere and from mankind within river water, that is, the recycling mechanism and the physical, chemical and biological process, where oceans absorb and transfer CO2 in atmosphere and ocean will change with season, area and space. Loa Monitoring Station found that atmosphere carbon is not affected by partial carbon emission and the data of the carbon reflects the change of atmosphere carbon in north Pacific. The data from Mauna Loa Monitoring Station were valid and reliable, which were used by many researchers [10,11,12,13]
