The study looked at how the pH levels in Jiaozhou Bay changed over time and space, and how this affected the growth of marine organisms. They found that from May to October, the pH in the bay increased, making it more favorable for marine life to thrive. The pH levels in the bay were relatively high and stable during these months, creating a good environment for marine organisms to grow. The researchers observed that the pH levels in the bay mouth and surrounding areas also increased over time, further supporting the growth of marine life in the bay.
