Abstract: A seagrass planting system that includes a planting spike. The planting spike includes: a tine end feature having a converging portion and a base portion having disposed thereon a seagrass securing mechanism for securing a seagrass segment; an alignment guide feature extending from the base portion, spanning from a first end to second end, and including a first alignment edge and a second alignment edge disposed on an area located between the first end and the second end; and force receiving feature extending at an angle relative to the second end.

Abstract: A securing clip includes: an enclosure body including a first end, a second end, and one or more sidewalls that extend between the first end and the second end; one or more fragment module securing tangs extending, from one or more of the sidewalls, into the cavity such that when at least a portion of the fragment module is placed within the cavity, at least a portion of the fragment module securing tang is designed to engage with the fragment module and prevents and/or impedes removal of at least a portion of the fragment module from the cavity; and one or more substrate securing tangs extending from the enclosure body and away from the cavity, each substrate securing tang designed to prevent and/or impede removal of the securing clip when the securing clip is placed into a substrate aperture defined within the substrate.

Abstract: A tether guide operable through a wide range of tether/fleeting angles while causing minimal wear and having a reduced size compared to a levelwind wheel. The tether guide may include a series of rollers approximating the curved shape and radius of levelwind wheel. The tether guide may include downward facing guide wings matched to a curved roller profile, but flaring out to capture and guide tether into rollers. Sensors may be included on the tether guide to provide information about tether location, including whether the tether is engaged in the tether guide.

Abstract: A system for carrying a tether guide, including a counter-balanced support system with two pivot points, where a first pivot allows the tether guide to travel up and down and the second pivot allows the tether guide to match the tether angle. Both pivots may be passive pivots. A shuttle that carries the tether guide may be electronically cammed to follow variable pitch helical grooves of a winch drum as the tether guide traverses across the drum length.

Abstract: A tether guide system operable through a wide range of tether/fleeting angles while causing minimal wear to the tether. The tether guide system may include a series of rollers arranged in a curved path. Also disclosed are tether guides with a sliding belt, a guide surface, or a guide wheel, all for use in the disclosed tether guide system.
