Marine environment vertical gradient simulation experiment device

Abstract

A marine environment vertical gradient simulation experiment device comprises a base, a barrel and a top cover, the barrel is composed of a series of layer blocks, and each layer block is provided with an independent temperature control module, an independent illumination control module, an independent substance concentration control module and an independent environment monitoring module. Through independent control of the temperature, illumination and substance concentration of each layer block, the vertical profile gradient change of the temperature, illumination and substance concentration of the marine environment can be simulated, and an unprecedented simulation experiment device is provided for marine ecosystem research under climate change. The method has good expansibility and applicability, the simulation precision and the construction cost of the vertical section can be controlled by increasing and decreasing the number of the layer blocks, and the requirements of different experiment purposes are met.

Description

technical field [0001] The invention relates to the field of marine environment, in particular to a marine environment vertical gradient simulation experiment device. Background technique [0002] Human activities have led to a significant increase in the concentration of greenhouse gases represented by carbon dioxide, and the problem of climate change with global warming as the main feature has become increasingly prominent, becoming one of the most severe challenges to human sustainable development. As the largest active carbon pool on earth, the ocean absorbs nearly one-third of the carbon dioxide emitted by human beings and acts as a "buffer" for climate change. However, in the process of mitigating climate change, the ocean is also deeply affected by climate change. For example, the absorption of carbon dioxide from the atmosphere by the ocean will change the balance of the seawater carbonate system, causing "ocean acidification", which in turn changes the community st...
