Systems and methods for monitoring ocean-based carbon dioxide removal devices and accumulation of a target product
An apparatus includes a first member having a housing that encloses a power source and a controller, a second member coupled to the first member that is seeded with a target product, and a sensing module coupled to the first member to allow power from the power source to be transmitted to the sensing module and sensor data from the sensing module to be transmitted to the controller. The sensing module including a sensor oriented toward at least a portion of the second member. The sensor configured to obtain sensor data associated with at least one characteristic of the target product.
1. A method, comprising:
releasing a deployment of passive substrates into a portion of a body of water, the passive substrates being seeded with a target product, the deployment including a sensor buoy, the sensor buoy including a first member configured to at least temporarily maintain a positive buoyancy of the sensor buoy, a second member seeded with the target product, and a sensing module having a sensor oriented toward at least a portion of the second member;
obtaining sensor data associated with at least one characteristic of the target product of the second member;
allowing the passive substrates and the target product seeded thereon to sink as a result of the passive substrates transitioning from a positively buoyant state to a negatively buoyant state;
determining, based at least in part on the sensor data, an amount of biomass accumulation associated with the target product of the second member when the passive substrates transition to the negatively buoyant state; and
determining a carbon sequestration capacity associated with the target product of the passive substrates based at least in part on the amount of biomass accumulation associated with the target product of the second member.
2. The method of claim 1 , further comprising:
retrieving the sensor buoy after allowing the passive substrates to sink.
3. The method of claim 1 , wherein the sensor buoy includes a scuttling device, the scuttling device includes a chamber that defines an inner volume in communication with an inner volume of the first member, a plug movably coupled to the chamber, and a motor disposed in the inner volume of the chamber, the method further comprising:
moving the plug, via the motor, from a closed state in which the chamber is sealed allowing the first member to maintain the positive buoyancy of the sensor buoy to an open state in which the plug allows a flow of water into the inner volume of the chamber.
4. The method of claim 3 , wherein the first member includes a one way valve in communication with the inner volume of the first member, the method further comprising:
transitioning the one way valve from a closed state to an open state in response to the flow of water into the inner volume of the chamber;
allowing air to flow out of the inner volume of the first member while the one way valve is in the open state until the sensor buoy becomes negatively buoyant; and
allowing the sensor buoy to sink as a result of becoming negatively buoyant.
5. The method of claim 3 , further comprising:
remotely actuating the motor to move the plug from the closed state to the open state.
6. The method of claim 1 , wherein each passive substrate from the plurality of passive substrates is formed from natural materials.
7. The method of claim 1 , wherein each passive substrate from the plurality of passive substrates is formed at least in part from wood.
8. The method of claim 1 , wherein the sensor includes at least an image capturing device, the sensor data associated with at least one characteristic of the target product of the second member includes imaging data of the target product of the second member captured by the image capturing device.
9. The method of claim 1 , wherein the passive substrates are configured to transition from the positively buoyant state to the negatively buoyant state after a period of time of the target product accumulating biomass.
10. The method of claim 1 , further comprising:
obtaining, at the sensor buoy, data associated with at least one environmental characteristic of the portion of the body of water in which the deployment is deployed, and
wherein the determining the amount of biomass accumulation includes determining the amount of biomass accumulation based on the sensor data and the data associated with the at least one environmental characteristic.
