Abstract

Method and system is described for marine surveying. The method involves operations for exploring and developing hydrocarbons with one or more unmanned vehicles. The unmanned vehicles are used to perform marine surveying and to obtain one or more samples that may be used to identify chemical, hydrocarbon and/or biologic information, which may be used for environmental monitoring of bodies of water.

First claim

The invention claimed is:

1. A method for performing a marine survey comprising:
a) transporting a plurality of sample containers on an unmanned vehicle to a potential location of target material in a body of water, wherein the target material comprises one or more of biological, chemical, hydrocarbons, and any combination thereof and wherein the unmanned vehicle is one of unmanned surface vehicle and an unmanned airborne vehicle;
b) detecting the presence of the target material in the body of water and if the target material is present in the body of water obtaining a sample of the target material;
c) disposing the obtained sample into one of the plurality of sample containers on the unmanned vehicle; and
d) repeating the steps (b) to (c) for another sample, wherein the obtained samples are stored in individual sample containers of the plurality of sample containers.

2. The method of claim 1 , further comprising performing remote sensing in a survey area to identify the potential location of the target material.

3. The method of claim 1 , further comprising inhibiting microbial or enzymatic activity from the obtained sample.

4. The method of claim 1 , wherein obtaining the sample of the target material comprises:
contacting sampling material from one of the plurality of sample containers with the target material; and
retrieving the sampling material having adhered target material as the obtained sample into one of the plurality of sample containers.

5. The method of claim 1 , wherein obtaining the sample of the target material comprises:
unsealing a sampling vessel to obtain a fluid;
sealing the sampling vessel with the fluid disposed within the sampling vessel;
retrieving the sampling vessel having the fluid disposed within the sampling vessel as the obtained sample into one of the plurality of sample containers.

6. The method of claim 1 , further comprising
identifying an additional sampling location to obtain one or more of sediment samples, biological samples, chemical samples, other non-hydrocarbon samples and any combination thereof;
directing the unmanned vehicle to the identified additional sampling location;
obtaining one or more samples at the identified additional sampling location;
obtaining one or more samples at the identified additional sampling location; and
analysing the obtained sample for geochemical or biological materials.

7. The method of claim 1 , wherein obtaining the sample of the target material comprises:
acquiring one or more images with an imaging module associated with at least one sampling container; and
retrieving the sampling container as the obtained sample into one of the plurality of sample containers.

8. The method of claim 1 , further comprising:
performing a large pattern search from the potential location, wherein the large pattern search comprises detecting the target material;
if the target material is detected, performing a sampling pattern search to obtain the sample; and
if the target material is not detected, determining whether to continue the large pattern search.

9. The method of claim 1 , wherein detecting the presence of the target material comprises searching for target material by pumping fluid through a target detection module to identify the target material.

10. The method of claim 1 , wherein detecting the presence of the target material comprises searching for the target material by analysing the surface of the body of water to detect certain wavelengths to identify the target material.

11. The method of claim 1 , wherein detecting the presence of the target material comprises searching for the target material by:
deploying an unmanned aerial vehicle above the unmanned vehicle;
obtaining electromagnetic radiation images with the unmanned aerial vehicle; and
analysing the infrared and visible light images to identify the target material.

12. The method of claim 1 , wherein one or more of the plurality of sample containers is configured to:
unseal the sample container if target material is detected.

13. The method of claim 12 , wherein the sample container is configured to seal the sample container after a set period of time once the sample container has been unsealed.

14. The method of claim 1 , further comprising managing the temperature within the one of the one or more sample containers on the unmanned vehicle.

15. The method of claim 14 , wherein the temperature is maintained with the range between about 10° C. and about −100° C.

16. The method of claim 1 , further comprising deploying a distributed sensor network to identify locations of particular target materials.

17. The method of claim 1 , wherein obtaining the sample of the target material comprises:
passing a fluid through a sampling conduit to interact with a sampling material;
interrupting the fluid passing through the sampling conduit; and
using the sampling conduit as the sample.

18. The method of claim 1 , wherein obtaining the sample of the target material comprises:
passing a fluid through a filter;
passing the fluid through a solid phase extraction module; and
using the filter and the solid phase extraction module as the sample.

19. The method of claim 1 , wherein detecting the presence of the target material comprises:
pumping a fluid from the body of water through a target measurement device to indicate the presence of the target material; and
notifying the sampling component to obtain a sample if the target material is present.

20. A marine target identification system comprising:
an unmanned vehicle having a propulsion component, a communication component, a target detection component, and a sample component, wherein the propulsion component is configured to maneuverer the unmanned vehicle, the target detection component is configured to identify target material, the sample component is configured to obtain one or more samples of a target material, and the communication component is configured to communicate signals associated with the obtained samples, wherein the target material comprises one or more of biological, chemical, hydrocarbon, and any combination thereof, and wherein the unmanned vehicle is one of unmanned surface vehicle and an unmanned airborne vehicle.

21. The system of claim 20 , wherein the sample component comprises a sample assembly having a plurality of individual sampling containers.

22. The system of claim 20 , wherein one or more of the plurality of individual sampling containers has a sampling vessel that is configured to unseal the sampling vessel to obtain the target material; and seal the sampling vessel with the target material disposed within the sampling vessel.

23. The system of claim 20 , wherein the target detection component comprises a target detection module and a pump, wherein the pump is configured to obtain surface compounds and pass the surface compounds to the target detection module to identify the target material.

24. The system of claim 23 , wherein the target detection component comprises a receiver configured to receive images; and analyse the images to identify certain wavelengths associated with the target material.

25. The system of claim 20 , wherein the unmanned vehicle has a camera configured to obtain one or more images as one or more samples are obtained.

26. The system of claim 20 , further comprising a deployment unmanned vehicle having a deployment propulsion c
