| Research Abstract |
Underway observations of carbon dioxide (CO_2) partial pressure were conducted in Tokyo Bay, and budget of CO_2 between surface water and atmosphere was evaluated。 At the innermost, low-salinity waters of the bay, CO_2 was continuously released to atmosphere due to oversaturation。 In most parts of the bay, however, CO_2 was taken up extensively during spring and summer, presumably by net photosynthesis of organic matter, and was nearly close to atmospheric equilibrium during autumn and winter。 The entire bay was a significant net sink of atmospheric CO_2。
