System and research method for long-term acidification adaptability research of large marine algae

Abstract

The invention discloses a system and research method for a long-term acidification adaptability research of large marine algae, and belongs to the field of algae physiological ecology. The system comprises a culture workshop and a workshop long-running water system, the workshop location is selected within 1 km from a natural sea area, and the roof of the workshop is translucent glass fiber reinforced plastic tiles; the workshop long-running water system comprises a water storage tank, a carbon dioxide enrichment tank and an algae culture tank; water in the water storage tank is diverted fromthe natural sea area, the water storage tank, the carbon dioxide enrichment tank and the algae culture tank communicate by drainage pipes, and the drainage pipes are equipped with valves to control water inlet amounts and water outlet amounts; and the carbon dioxide enrichment tank is equipped with a carbon dioxide enrichment machine to adjust the pH value of sea water by an aeration method. According to the system, a relatively stable seawater acidification culture system for large algae is established through a method that the workshop long-running water carbon dioxide enrichment system communicates with the natural sea area, and a pilot scale research on long-term acidification adaptability of large algae developed under natural conditions is realized by using the system.

Description

technical field [0001] The invention belongs to the field of marine environment monitoring, and in particular relates to a system and a research method for studying the long-term acidification adaptability of large marine algae. Background technique [0002] Affected by global climate change and human activities, carbon dioxide (CO 2 ) emissions continued to increase. As a natural carbon dioxide storage pool, the ocean absorbs about 30% of the total carbon dioxide emitted by humans, causing ocean acidification. Since the Industrial Revolution, the pH of the ocean surface has dropped by 0.1 units. By 2100, the value is projected to decline further by 0.3 to 0.4 units. The increase in seawater acidity will change the chemical balance of seawater, and pose a huge threat to various marine organisms and even ecosystems that depend on the stability of the chemical environment. In the process of irreversible ocean acidification, algae must adjust physiologically, biochemically ...

Problems solved by technology

However, more and more studies have found that indoor simulation experiments have space limitations, and the experimental period is short, which makes it difficult to reflect the physiological adaptability of algae to ocean acidification under natural conditions; on the other hand, although a few foreign scholars use pH differences in natural sea areas Carry out long-term adaptability research, but it is difficult to maintain a relatively stable seawater carbonate system, and the repeatability of the experiment is poor
