Application:
Sediment traps are small containers placed in the water to collect particles falling toward the sea floor. The traps collect tiny sediment or larger accumulations called marine snow - made up of organic matter, dead sea creatures, tiny shells, dust and minerals.

General:
The construction of the sediment trap array ensures a permanently vertical position of the sampling tubes during deployment. The steering fin (optional) and the pivot joints force the array to be held at right angle to the current. Once the sampling period is done, a drop messenger (sold separately) causes the lids to close to avoid any contamination when retrieving the sampler through the water column.

Options:
The system is fully configurable. All parts are detachable and the main rack can be attached with 1, 2, 3 or 4 tubes to suit your needs for analysis. The sediment trap consists of detachable cylindrical sampling tubes mounted with lead weights at the bottom. The gimballed tube holders and fin are made of AISI 316 stainless steel. The tubes are made of partially transparent PVC and have an aspect ratio above 6.

Available models with Ø80 mm tubes with lids:
• 1 tube, 1 steering fin.
• 2 tubes.
• 2 tubes, 1 steering fin, 1 balance arm.
• 3 tubes, 1 steering fin.
• 4 tubes.

Sample volume:
• 1.9 L for each tube.

Note: All sizes of tubes can be manufactured upon request.

Deployment methods:
Seen to the image 10 is the 2 most common options of deployment for the sediment trap station system, the schematics are for your general information. Cannot estimate any details for buoys, anchors etc., as local conditions, current and depth range, etc., are to be considered and tested in practice.
