阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

A study in the journal Nature suggests that the color of our oceans is changing due to climate change. Over the past 20 years, low-latitude oceans 【小题1】 (become) greener. It’s well established that rising global temperatures, 【小题2】 (drive) by the burning of fossil fuels, are making dramatic changes to our oceans, from increasing sea levels and intensifying storms to acidifying (酸化) the water itself.

【小题3】 NASA satellite known as Aqua just celebrated its 21st birthday in May, making it one of the longest still-running space probes. It has collected a lot of data on the color of our oceans, which is 【小题4】 (actual) an essential climate variable (变量) and can reflect changes in ocean ecosystems. After analyzing the data, researchers found that, 【小题5】 average, our oceans are becoming greener, with significant shifts in about 56% of the ocean surface.

The 【小题6】 (result) suggest that the effects of climate change are already being felt in surface marine microbial (微生物) ecosystems, 【小题7】 those effects have not yet been detected. Therefore, the findings might be useful for ocean 【小题8】 (conserve) and management. For instance, knowledge of places 【小题9】 the surface-ocean microbial ecosystem is changing might be useful for identifying regions of the open ocean 【小题10】 (set) up marine protected areas.
