Description

Results of laboratory experiments examining growth and N2-fixation rate of two isolates of Crocosphaera watsonii, WH0401 and WH0402, in response to three levels of CO2 (190, air, and 750) at a light intensity of 155 umol quanta m-2 s-1. Isolates of C. watsonii, a unicellular marine N2-fixing cyanobacterium, were obtained from the western tropical Atlantic Ocean and cultured in the laboratory.

Detailed methods and results are described in the following publication (see Figure 2):
