Embodiment 1
[0085] OCAM
[0086] The Georgian cotton fiber is needle-punched felting, thus the preparation has a width of 0.91 m, a length of 4.54 m and a length of 4.12 m 2 Surface area of cotton fiber matrix. Then the tablets are sprayed with saturated alumina on both sides of the tablets. The sheet was then dried and used in the field test described below.

[0088] Materials and methods for field test
[0089] Regarding field deployment, two locations can be selected for field trials. The ship used for the operation is LUMCON’s RJV Whiskey Pass, a 9m single-hull open structure ship powered by two high-power outboard motors.
[0090] The first location (location 1) is Timbalier Island (29°05'N, -90°32'W) south of Cocodrie, Louisiana. Deploy at the northwestern tip of the island, as an intermediate-scale vortex is suspected in this area. This is due to the known major coastal currents from the east and the southwardly curved crescent of the island. Immersion oil or surface oil may be present here.
[0091] At this location, we use two immersion sampling devices in sequence. Each device consists of a 0.9×4.5m piece of sheet-shaped adsorbent material, fixed to two sections of steel bars (one at each end). Wrap the material around the rebar and fix it with cable ties. The material is towed from a rod connected to the bow and extending t...

[0100] Field observation results
[0101] For location 1, a front part with some accumulated drifts was observed, indicating a vortex type morphology. The boat drifted generally in a circular shape during sampling, which also indicated that there were small intermediate-scale vortices in this area.
[0102] When the first piece of material was retracted, it was visibly discolored with a slight black tint. We retracted the device and wringed as much as possible (first try) into the pre-labeled 950ml EPA standard prepared amber bottle. We did not get a lot of substances from this operation, about 1-2 bottles of liquid plus dissolved and suspended substances.
[0103] When the second immersion sampling device was withdrawn, almost all the sampled materials were dark-dark gray to black. It is also obvious from the bottom of the material that we have used it to reach the bottom sediment. With the second immersion device using a more effective hand-twisting method, we increased the amo...
