A cutting device for coupling to a water vessel propelling device. The cutting device comprises a base extending between a proximal end and a distal end and is coupled to a shaft of the water vessel propelling device. An upper arm is coupled to the base. A lower arm is coupled to the base. A track extends along the base. A blade slidably engages within the track for displacing between the upper arm and the lower arm. An actuator displaces the blade relative to the track. A cutting edge is on the blade for severing a foreign object that is positioned between the upper arm and the lower arm of the base.

The application describes a system for harvesting seaweed. The system includes a frame structure (202) and a first device mounted (204,206) on the frame structure. The first device receives a tube net comprising the seaweed and selectively separates its apical tips protruding out of the tube net. The systems also includes a second device (212,214) mounted on the frame structure for receiving the tube net comprising partially harvested seaweed.

The present disclosure relates to apparatus and methods of seaweed farming and harvesting, and improvements relating thereto.

Disclosed are a system and method for growing and/or monitoring macroalgae and aquatic plants in a large body of water. The method includes placing a mass or collection of the seaweed/aquatic plants in the body of water at a location where the water is at least 300 meters deep, and monitoring a depth of the seaweed/aquatic plants until the seaweed/aquatic plants sink below a sequestration threshold depth. The system includes a platform on or from which the seaweed or aquatic plants are grown, wireless detection equipment on the platform, and a wireless data signal transmitter on the platform, configured to transmit a wireless signal that indicates a depth of the sinking seaweed or aquatic plants.
