Description

A device for measuring primary production of seaweed and a system including the same {AN APPARATUS FOR MEASURING PRIMARY PRODUCTION OF BENTHIC ALGAL AND A SYSTEM COMPRISING THE SAME}

The following description relates to an apparatus for measuring primary production of seaweed and a system including the same.

The activity in which autotrophs in an ecosystem produce organic matter from inorganic matter for a certain period of time is called primary production, and the amount of organic matter produced at this time is called primary production. Organic matter produced by primary production can be a source of growth for the next-stage organisms in the food chain, and the basis for the survival of all other organisms. Therefore, primary production is considered an important factor in maintaining the ecosystem.

Primary production occurs in ecosystems where autotrophs survive, such as terrestrial and marine ecosystems, and about 50% of the planet's total primary production occurs in marine ecosystems. In addition, it is estimated that about 7% of the primary production of marine ecosystems is contributed by coastal algae. For example, seaweed serves as a primary producer of oxygen and nutrients through photosynthesis. Furthermore, it is also a direct prey for marine life. Therefore, the vegetation of coastal algae plays a key role in energy transfer and biogeochemical circulation in marine ecosystems.

Meanwhile, with recent global warming, the concentration of carbon dioxide in seawater is increasing. Increasing the concentration of carbon dioxide in seawater causes changes in the marine environment and destroys marine ecosystems. For example, fish may lose their sense of smell, their populations may decline rapidly, and crustacean marine life may interfere with the growth of the shell. At this time, if the productivity of the seaweed is high, the seaweed can accelerate the removal and fixation of carbon dioxide in seawater. Therefore, the role of seaweed in order to maintain a healthy marine ecosystem is being emphasized.

However, while studies on the measurement of primary production of coastal algae have been conducted for a long time, effective measurement methods and research results are very lacking. For example, a device for measuring the primary production of seaweed generally has a closed chamber structure. However, the closed chamber has problems such as lack of carbon dioxide and nutrients inside the chamber. Eventually, the primary production of seaweed may not be properly measured. Therefore, there is a need for additional techniques for measuring the primary production of seaweed and seaweed forests.
In this regard, Korean Laid-Open Patent Publication No. 10-2011-0075385 (2011.07.06) discloses a seaweed farm using seaweed and a method of calculating the amount of carbon dioxide and total inorganic carbon removed therefrom.

Hereinafter, with reference to the accompanying drawings, a description will be given of an apparatus 1 for measuring a primary production amount of seaweed and a system 2 for measuring a primary production amount of seaweed including the same according to embodiments.

In the present specification, the primary production of seaweed refers to the amount of organic matter produced by seaweed from inorganic matter for a certain period of time. And, measuring the primary production amount of seaweed means measuring the amount of organic matter produced by the seaweed. In one embodiment, it may include measuring the concentration of oxygen generated by the algae through photosynthesis.

1 is a perspective view of an apparatus 1 for measuring a primary production amount of seaweed according to an embodiment. Referring to FIG. 1, the apparatus 1 for measuring the primary production amount of seaweed according to an embodiment includes a chamber 10, a pump 11, a sensor 12, and a supply pipe 13.

The chamber 10 has a space for accommodating the algae 30 therein. The shape of the chamber 10 has a shape of a horn, a horn, and a column, and the bottom surface has a shape of a polygon or a circle. For example, the chamber 10 may have a square truncated shape, as shown in FIG. 1. However, this is only an example, and the shape of the chamber 10 is not limited by the drawings.

At one side of the frame of the chamber 10, a hinge may be provided to put the seaweed 30 therein. For example, when a hinge is provided, a finishing material such as rubber may be used so that the chamber 10 is completely sealed. However, the means for sealing the chamber 10 is not limited to a hinge, and may include various means for inserting the seaweed 30 into the chamber 10 by an opening or closing method or a switch method.

The side surface of the chamber 10 is composed of a film through which light can pass. When the shape of the chamber 10 has a shape of a horn and a pillar, the upper surface of the chamber 10 is also composed of a film through which light can pass. As for the kind of film, an acetate film having high light transmittance may be used, for example.

The chamber 10 is connected to the pump 11 to continuously receive seawater outside the chamber 10 into the chamber 10. Accordingly, the chamber 10 has a flow-through structure in which external seawater is continuously supplied.

The chamber 10 and the pump 11 are connected through a supply pipe 13. The supply pipe 13 may be a separate component or may be fixed to one side of the chamber 10 or the pump 11. In addition, the chamber 10, the pump 11, and the supply pipe 13 may be integrally formed. The positions of the chamber 10, the pump 11, and the supply pipe 13 are not limited to the drawings, and any positions capable of connecting the chamber 10 and the pump 11 to the supply pipe 13 are possible.

The pump 11 may be driven by a battery connected to one side of the pump 11. However, the battery is only an embodiment, and the pump 11 may be directly connected to a power source, or another separate driving supply source capable of driving the pump 11 may be connected.

Two or more sensors 12 are provided, including an internal sensor provided inside the chamber 10 and an external sensor provided outside the chamber 10.

The type of sensor 12 may be an oxygen concentration measuring sensor capable of measuring the amount of dissolved oxygen in the space in which the sensor 12 is provided. In addition, it may be an atmospheric pressure sensor that measures the atmospheric pressure of carbon dioxide. However, the oxygen sensor and the barometric pressure sensor mentioned are only one embodiment, and various sensors for measuring the primary production amount of seaweed 30 inside the chamber 10 are possible.

Meanwhile, the sensor 12 may further include an optical sensor that measures the amount of light transmitted into the chamber 10. Using the measured value of the optical sensor, a relational expression between photosynthesis and irradiance of the seaweed 30 can be secured, and the result of measuring the primary production amount of the seaweed 30 and the measurement environment can be modeled. However, the optical sensor is not an essential element in measuring the primary production amount of seaweed 30.

Hereinafter, when the sensor 12 is the above-described oxygen concentration measuring sensor, measuring the primary production amount of the seaweed 30 inside the chamber 10 using the first production amount measuring device 1 of seaweed shown in FIG. 1 Examples will be described.

For example, a first internal oxygen sensor 121 for measuring the amount of dissolved oxygen in the chamber 10 is provided inside the chamber 10, and an external oxygen sensor 122 for measuring the amount of dissolved oxygen in seawater outside the chamber 10 ) Is provided outside the chamber 10. In this case, the primary production amount of seaweed 30 inside the chamber 10 may be measured using Equation 1 below.

However, the measurement of the primary production amount of seaweed 30 using Equation 1 is only an example, and the formula for measuring the primary production amount of seaweed 30 is not limited to Equation 1 above.

In addition, if the relationship between the amount of dissolved oxygen and the atmospheric pressure of carbon dioxide in the sea area in which the primary production amount of the seaweed 30 is to be measured is checked, the carbon dioxide removal and fixation rate of the seaweed can be obtained according to the dissolved oxygen amount measured by the oxygen sensor.

4 is a graph showing a relationship between time and dissolved oxygen and time and carbon dioxide pressure in a sea area in which the apparatus 1 for measuring the primary production amount of seaweed is installed according to an embodiment. Referring to FIG. 4, a pattern in which the amount of dissolved oxygen increases during the daytime when the amount of light is relatively high, and decreases the amount of dissolved oxygen during the night time when the amount of light is relatively low. In addition, it can be seen that the carbon dioxide atmospheric pressure increases or decreases in an inverse relationship with the amount of dissolved oxygen with respect to the amount of light. Since the amount of dissolved oxygen and the atmospheric pressure of carbon dioxide are controlled by biological factors, such a strong correlation exists.

5 is a graph showing the relationship between the amount of dissolved oxygen and the concentration of carbon dioxide that can be confirmed from FIG. 4. Referring to FIG. 4, it can be seen that the concentration of carbon dioxide decreases as the amount of dissolved oxygen increases, and the concentration of carbon dioxide increases as the amount of dissolved oxygen decreases. Accordingly, it can be confirmed that the dissolved oxygen amount and the carbon dioxide concentration have an inverse relationship, and can be expressed by Equation 2 below.

Meanwhile, in the above-described embodiment, the apparatus 1 for measuring the primary production amount of seaweed comprising one chamber 10 is illustrated, but the chamber 10 may be provided in plural.

2 is a perspective view of an apparatus for measuring primary production of seaweed according to another embodiment.

In the following description, except that the blank chamber 101 and the second internal oxygen sensor 123 are further included in the primary production amount measuring apparatus 1 of seaweed according to the embodiment described with reference to FIG. The same symbols are used for constituent elements, and duplicate descriptions are excluded.

Referring to FIG. 2, the apparatus for measuring the primary production amount of seaweed according to another embodiment includes an experimental group chamber 10, a blank chamber 101, a pump 11, a sensor 12, and a supply pipe 13 containing seaweed. It consists of including. The experimental group chamber 10 and the blank chamber 101 accommodating the seaweed may be provided in plural to increase the accuracy of the measurement of the primary production amount of the seaweed 30, but is not limited to the drawings.

The blank chamber 101 has the same conditions as the experimental group chamber 10 containing seaweed, except that it does not contain seaweed therein. That is, the blank chamber 101 serves as a control group that does not contain seaweed under the same conditions.

The blank chamber 101 is connected to one side of the pump 11 to continuously receive seawater outside the blank chamber 101 into the blank chamber 101. At this time, the pump 11 may supply external seawater to the inside of the blank chamber 101 under the same conditions as the experimental group chamber 10 containing seaweed.

In addition to the above-described, internal sensor and external sensor of the experimental group chamber 10 containing seaweed, three or more sensors 12 may further include a sensor inside the blank chamber 101.

Hereinafter, by further providing the blank chamber 101 and the sensor inside the blank chamber 101, an embodiment in which the accuracy of the primary production measurement of the seaweed 30 inside the experimental group chamber 10 containing the seaweed can be improved will be described.

For example, the sensor 12 is an oxygen concentration measuring sensor. A first internal oxygen sensor 121 is provided inside the experimental group chamber 10 containing seaweed, and an external oxygen sensor 122 is provided outside the experimental group chamber 10. In addition, a second internal oxygen sensor 123 is further provided inside the blank chamber 101.

Here, from the amount of dissolved oxygen measured by the first internal oxygen sensor 121 inside the experimental group chamber 10 containing seaweed, the amount of dissolved oxygen measured by the second internal oxygen sensor 123 inside the blank chamber 101 as a control group By excluding, it is possible to measure the primary production amount by pure seaweed. That is, it is possible to increase the accuracy of measuring the primary production amount by the seaweed 30 inside the experimental group chamber 10 containing the seaweed.

In addition, as a difference between the amount of dissolved oxygen measured by the second internal oxygen sensor 123 and the amount of dissolved oxygen measured by the external oxygen sensor 122, the primary production amount of other microbial communities in the sea area where the measuring device is installed can be separately measured. . For reference, to measure the primary production amount from the dissolved oxygen amount, refer to Equation 1 above.

That is, according to the above-described embodiment, by providing the blank chamber 101 and the sensor inside the blank chamber 101, it is possible to increase the accuracy of measuring the primary production amount of the seaweed 30 inside the chamber 10 containing the seaweed. In addition, in the same manner as described above, by using the relationship between oxygen and carbon dioxide in the sea area where the measuring device is installed, the carbon dioxide removal ability of the seaweed and microbial community can be measured.

On the other hand, a seawater detection unit 20, a user operation panel unit 21, and a control unit 22 are further included in the above-described primary production amount measurement device 1 to provide a system for measuring the primary production amount of seaweed (2). I can.

3 is a block diagram for explaining the system 2 for measuring the primary production of seaweed. In this embodiment, except for the seawater detection unit 20, the user operation panel unit 21, the control unit 22, and the flow rate customized pump 111, except for the same configuration as the above-described embodiments, the same component Symbols are used, and redundant descriptions are omitted.

Referring to Figure 3, the primary production amount measurement system 2 of seaweed is a chamber 10, a customized flow rate pump 111, a sensor 12, a supply pipe 13, a seawater detection unit 20, a user operation panel unit ( 21) and a control unit 22.

The seawater detection unit 20 is provided around the apparatus 1 for measuring the primary production amount of seaweed, and detects the oxygen concentration of seawater outside the chamber 10 and the vegetation density of seawater outside the chamber 10. The location of the seawater detection unit 20 is not limited to the drawings, and any location capable of detecting the oxygen concentration of the outer seawater and the vegetation density of the surrounding seawater is possible.

The user operation panel unit 21 is connected to one side of the seawater detection unit 20 and includes a notification unit 211 and an operation unit 212. When the seawater detection unit 20 receives data on the oxygen concentration and vegetation density of external seawater, the notification unit 211 shows the received data. The operation unit 212 adjusts the flow rate of seawater supplied from the flow rate customized pump 111 to the chamber 10 according to the data checked by the notification unit 211.

For example, when the oxygen concentration of the external seawater detected by the seawater detection unit 20 is high, the operation unit 212 rapidly adjusts the flow rate of seawater supplied into the chamber 10 from the flow rate-customized pump 111. In addition, when the vegetation density of external seawater detected by the seawater detection unit 20 is high, the manipulation unit 212 rapidly adjusts the flow velocity of the seawater. In this way, by adjusting the flow rate of the flow rate customizable pump 111 with the control unit 212, the environment outside the chamber 10 and the inside of the chamber 10 can be similarly set. However, this is only an example, and the flow rate can be variously adjusted according to various environments of external seawater.

The control unit 22 is further provided on the other side of the seawater detection unit 20. The control unit 22 automatically adjusts the flow rate of seawater supplied to the chamber 10 from the flow rate customized pump 111 according to the oxygen concentration and vegetation density of the external seawater detected by the seawater detection unit 20. That is, the control of the operation unit 212 of the user operation panel unit 21 is automatically performed.

As described above, the system for measuring the primary production amount of seaweed includes the operation unit 212 or the control unit 22 of the user operation panel unit 21, so that the environment outside the chamber 10 and the inside of the chamber 10 are similar. Can be set. After setting the environment outside the chamber 10 and the inside of the chamber 10 similarly, measurement accuracy may be improved by measuring the primary production amount of seaweed 30.
