点一下不认识的单词。
Scientists from NOAA have placed new devices called Sofar Spotter buoys at important coral reef sites in the Florida Keys National Marine Sanctuary. These buoys help monitor the ocean's condition to protect the reefs.
The buoys float on the sea surface and measure wave energy, wind speed, sea surface temperature, and pressure. Underwater sensors also check the pH level and temperature near the seafloor in real time. This information shows how ocean acidification affects the reefs.
Ocean acidification happens when the ocean absorbs more carbon dioxide from the air. This causes the water to become more acidic and harms the coral reefs. The coral’s hard, calcium carbonate structure starts to erode and grow less. This damage threatens the many marine animals that live in the reefs.
Scientists will use the data from these buoys to better understand and protect coral reefs. The information helps them watch changes in the ocean and plan how to restore these important habitats.

难句解析
- 1
Scientists from NOAA have placed new devices called Sofar Spotter buoys at important coral reef sites in the Florida Keys National Marine Sanctuary.
难点在于“called Sofar Spotter buoys”是过去分词短语作定语，修饰“new devices”，意思是“被称为 Sofar Spotter 浮标的新设备”。整句：NOAA 的科学家在佛罗里达群岛国家海洋保护区的重要珊瑚礁点部署了被称为 Sofar Spotter 浮标的新设备。
- 2
The coral’s hard, calcium carbonate structure starts to erode and grow less.
难点在于“erode and grow less”两个并列动词，意思是“开始被侵蚀并且生长变慢”。整句：珊瑚坚硬的碳酸钙结构开始被侵蚀，生长也变慢了。
- 3
The information helps them watch changes in the ocean and plan how to restore these important habitats.
难点在于“plan how to restore these important habitats”中“plan”后直接跟“how to do”结构，表示“计划如何做某事”。整句：这些信息帮助他们观察海洋变化，并规划如何恢复这些重要的栖息地。
