Disposable antifouling covers for geophysical survey equipment

1. A disposable antifouling cover for use with marine geophysical survey equipment, the disposable antifouling cover comprising:

a first elongate body of plastic material configured to occlude a majority of an exterior surface of a portion of the marine geophysical survey equipment, wherein the body of plastic material comprises:

a leading edge and an opposite trailing edge defined by the elongate body,

an exterior surface,

an interior surface, wherein the interior surface defines a negative image of a positioning device of the marine geophysical survey equipment,

an interior volume, and

a proximal end defined by the elongate body, the proximal end comprising an aperture into the interior volume.

2. The disposable antifouling cover of claim 1 wherein the elongate body defines the negative image of a wing of a positioning device.

3. The disposable antifouling cover of claim 1 wherein the exterior surface and the interior surface define complementary shapes such that the disposable antifouling cover is stackable by placing the disposable antifouling cover in an abutting relationship with another disposable antifouling cover.

4. The disposable antifouling cover of claim 1 wherein the exterior surface and the interior surface define complementary shapes such that the disposable antifouling cover is stackable by telescoping the disposable antifouling cover into another disposable antifouling cover.

5. The disposable antifouling cover of claim 1 further comprising a second elongate body of thin plastic material that defines an exterior surface, an interior surface, and an interior volume, the interior surface of the second elongate body defines a negative image of the portion of the marine geophysical survey equipment, and the second elongate body within and abutting the first elongate body.

6. The disposable antifouling cover of claim 1 further comprising a coating on the exterior surface configured to reduce marine growth on the exterior surface.

7. The disposable antifouling cover of claim 1 further comprising a latch feature defined by the elongate body proximate the aperture, the feature configured to provide a latch force when the disposable antifouling cover is installed on the portion of the marine geophysical survey equipment.

8. The disposable antifouling cover of claim 7 wherein the latch feature further comprises at least one selected from the group consisting of: a first flange member defined at the aperture, where the first flange member protrudes inward relative to the aperture; a protrusion defined on the interior surface; and a ridge defined on the interior surface.

9. The disposable antifouling cover of claim 1 wherein the thin plastic material has a thickness of one millimeter or less.

10. The disposable antifouling cover of claim 1 wherein the exterior surface further comprises at least one selected from the group consisting of: features no larger than 1 millimeter; features no larger than 0.1 millimeter; have features no larger than 0.01 millimeter; have micro-texture that reduces hydrodynamic drag; an anti-fouling coating.

11. The disposable antifouling cover of claim 1 wherein the disposable antifouling cover further comprises a deformable section configured to deform to provide a latching force to hold the disposable antifouling cover on the portion of the marine geophysical survey equipment.

12. The disposable antifouling cover of claim 1 wherein the deformable section comprises at least one selected from the group consisting of: a heat shrinkable section; a chemically shrinkable section; and an electromagnetic radiation shrinkable section.

13. A disposable antifouling cover for use with marine geophysical survey equipment, the disposable antifouling cover comprising:

a first elongate body of plastic material configured to occlude a majority of an exterior surface of a portion of the marine geophysical survey equipment, wherein the body of plastic material comprises:

a leading edge and an opposite trailing edge defined by the elongate body,

an exterior surface,

an interior surface, wherein the interior surface defines a negative image of a portion of the marine geophysical survey equipment,

an interior volume,

a proximal end defined by the elongate body, the proximal end comprising an aperture into the interior volume, and

a latch feature defined by the elongate body proximate the aperture, the feature configured to provide a latch force when the disposable antifouling cover is installed on the portion of the marine geophysical survey equipment.

14. The disposable antifouling cover of claim 13 wherein the latch feature further comprises at least one selected from the group consisting of: a first flange member defined at the aperture, where the first flange member protrudes inward relative to the aperture; a protrusion defined on the interior surface; and a ridge defined on the interior surface.

15. A disposable antifouling cover for use with marine geophysical survey equipment, the disposable antifouling cover comprising:

a first elongate body of plastic material configured to occlude a majority of an exterior surface of a portion of the marine geophysical survey equipment, wherein the body of plastic material comprises:

a leading edge and an opposite trailing edge defined by the elongate body,

an exterior surface,

an interior surface, wherein the interior surface defines a negative image of a wing of a positioning device of the marine geophysical survey equipment,

an interior volume, and

a proximal end defined by the elongate body, the proximal end comprising an aperture into the interior volume.
