CLAIMS

A modular agriculture system for use underwater, the system comprising:

a plurality of node elements (101) each including an agricultural unit:

a plurality of connection elements (201) for inter-connecting at least some of said nodes (101) to form a mesh-like structure with nodes (101) at the mesh junctions, said connection elements having a profile such that when in use and placed underwater they present a low resistance to the action of waves and currents;

a plurality of tensioning elements (310) for connection to the mesh-like structure to place the connection elements in tension; and

at least two anchor elements (301) for securing the mesh-like structure to the sea bottom. A system according to claim 1 wherein the connection elements have a low cross-section. A system according to any preceding claim wherein the or each agricultural unit (101) may be one of either a planter for seaweed and/or other underwater plants, or a feeder for fish and/or other underwater animals.

A system according to any preceding claim wherein at least some of the connection elements (201) are flexible.

A system according to any preceding claim, wherein at least one of the node elements (101) includes a coupling arrangement for a connection element which allows a connection element to move therethrough and thereby move relative to the node element. A system according to any preceding claim, wherein at least part of the connection elements (201) are biodegradable.

A system according to any preceding claim, wherein at least one of the node elements (101) includes a substrate to facilitate rooting of plants or seaweeds positioned on them. 8. A system according to any preceding claim, wherein the geometry of the inter-connected mesh-like structure comprising connection lines (201) and tensioning elements (301) is selected so that the tension applied via the tensioning element will distribute evenly through at least part of the mesh-like structure.

A system according to any of the preceding claim, wherein a or the anchor element (301) comprises a bottom fixture such as an anchor, or a surface penetrating component, a suction system, or a weight, or a combination of these.

10. A system according to any preceding claim, wherein a tensioning element comprises tension generating devices like coils, elastomers, pneumatic or hydraulic or

electromechanical actuators or ropes or cables pulled by floaters or by weights, possibly with the use of pulleys or other means to deviate the direction of the tension thus generated.

1 1. A system according to any preceding claim, wherein a node element (101) contains

means to distribute light or nutrients in its immediate vicinity.

12. A system according to any preceding claim, wherein a node element contains means to keep away or control predators or pests, like cages, sound emitters (possibly of very high or very low frequency), electromagnetic emitters (possibly of low frequency or of very high frequency, or of light) or substance emitters.

13. A system according to any preceding claim, wherein a node element contains fixtures like anchors or surface penetrating components or weights, or a combination of the above, to further reduce relative motion with respect to the ground.

14. A system according to any preceding claim, wherein a node element contains means to monitor the surrounding environment, means to mitigate the accumulation of sediments, to produce heat, to produce cold, to vary the percentage of some gases diluted in the surrounding water or any combination of the above.

15. A system according to any preceding claim, further including at least one service node element for inclusion in the mesh-like structure and containing means to provide useful services to the cultivation.

16. A system according to any preceding claim, wherein a node element or a service node element includes means for connection to power cables, to data cables or to pipes.

17. A system according to any preceding claim, further including a power hub, a data hub, a storage device or a combination of the above, for connection to a node element or service node element and/or to a connecting elements.

18. A system according to any preceding claim, further including one or more devices to convert into usable energy the mechanical energy from waves, the mechanical energy from currents, the light, the thermal energy from an underground reservoir, the salinity gradient, the thermal gradient or other sources of renewable energy.

19. A system according to any preceding claim, wherein the mesh-like structure of nodes and connecting elements is prepared in a way which allows for it to be deployed by an unmanned underwater vehicle.

20. A system according to any preceding claim, wherein the mesh of nodes and connecting elements is prepared in a way which allows for it to be assembled underwater by a mechanical system prior to deployment

21. A method of deploying the system of any of claims 1 to 20 comprising the steps of: i) providing at least two stores of tensioning lines at separated locations;

ii) connecting the tensioning lines from each of those stores to a controllably

moveable vessel;

Hi) withdrawing said tensioning lines from their respective stores by moving the respective vessels away from the respective stores of tensioning lines; and iv) attaching connection elements to and between said tensioning lines as they are withdrawn from the respective stores of tensioning lines.

22. A method according to claim 20 wherein the stores of tensioning lines are located on shore.

23. A method according to claim 21 or claim 22 wherein the stores of tensioning lines are each a roll of tensioning line.

24. A method according to any of claims 21 to 23 comprising the further steps of:

v) disengaging the tensioning lines from their respective stores once the mesh-like structure is complete; and

vi) towing a completed mesh-like structure away from the locations of the stores of tensioning line.

25. A method according to claim 24 wherein the ends of the tensioning lines disengaged from the stores are themselves connected to further controllably moveable vessels and the tensioning lines are kept in tension.

26. A method according to any of claims 21 to 25 wherein the controllably movable vessels may be remotely operated or manned, surface, aerial or underwater vessels or drones.
