The net was about 30 cm long had 0.333 mm nylon mesh. The system was lowered to the seafloor where an anchor attached to the net frame by a spool of line became fixed. The net was towed at ~1.5 knots away from the anchor until the line was fully extended whereupon it triggered a choke rope closing the net. Distance covered by the sampler was about 10 m. A scaled up version with 70.1 cm x 70.1 cm mouth opening also described [Wiebe and Benfield 2003 Plate 23 A]."@en ;

  skos:definition "A funnel-shaped net designed to trap organisms at its closed-end while being trawled along the seafloor. It is composed of a non-fixed wide mouth attached to the main wire and held open horizontally by an otter board at each side; a tickler chain is mounted across the lower edge of the net to keep it in contact with the ground, whereas a float fixed to the top of the net ensures its vertical spread. Typically, a semi-balloon otter trawl has a mouth size of approximately 2m x 8.5m; the net has a fine mash and it is mounted to a head rope of maximum 14m in length. This type of trawl is ideal for deep-water sampling of megafauna near the seafloor, mostly for conducting species diversity, abundance and biomass studies. The semi-balloon otter trawl is also known as OTSB, OTSB 14 and Marinovitch Trawl. Ref: Methods for the Study of Marine Benthos, fourth edition by WILEY Blackwell."@en ;

It was constructed of 4.4 cm stretch mesh body and 3.7 cm mesh intermediate and cod end, with a 1.3 cm inner liner in the cod end. Buoyancy on the headline was provided by one centrally placed glass sphere having a positive buoyancy of 5 kg. Twenty three 13 x 15 cm plastic mud rollers were spaced evenly along the footrope (17 m), with three loops of 6 mm chain in between each set. A pair of sweep lines on each side separated the \"V\" doors by 7 m from the wing ends of the net. The height of the wing ends between headline and footrope was 1.5 m. The doors, each measuring 1.5 x 1 m and weighing 180 kg; were connected by bridles 50 m in length, through a swivel to the single trawl warp. Reference: Merrett, N.R. and Marshall, N.B., 1980.

Bottles are typically lowered vertically through the water column although a horizontal version is available for sampling near the seabed or at thermoclines or chemoclines. Because of the lack of metal parts the bottles are suitable for trace metal sampling, although the blue polyurethane seal used in the Alpha version may leach mercury.

Instead of following the flow of the stream, the inertia of large (dense) particles causes them to hit the sides of the container and fall to the bottom, where they can be removed. The cyclone geometry and flow rate define a cut point, which is the size of the particle that will be removed from the stream with 50% efficiency.

It has a typical sampling area of 0.25 m2 (0.2 m2 - 0.29 m2) and a penetration depth up to 30 cm. This grab consists of a rectangular (but sometimes triangular) frame forming a stable support for a sampling bucket attached to a pivoted arm. On reaching the seabed, tension in the wire is released which causes the sampling bucket to pivot through 90 degrees pushing seabed sediment into the bucket. The bucket locates onto an inclined rubber-covered steel plate, sealing it completely. Weights are attached to the grab to minimize the lateral movement of the supporting frame during sample collection."@en ;

A pump collects up to 16 individual samples into gas-impermeable 250 ml bags, each within protective enclosures, which can be pre-filled with preservative. Sampling can be set-up via a Windows software interface, allowing the user to programme for water samples to be taken at specific times. It also has the capability for remote control sampling through an Iridium satellite interface, allowing remote sampling activation. Each bag fill can be performed either as a one shot operation, or as a repeat fill. The repeat fill feature allows a sample bag to be filled gradually over a period of time, with the amount of fill for each stage being preset through the user interface. Larger sampling bags can also be fitted as necessary. The sampler operates up to approximately 20 m depth, and can pump 100 ml in approximately 90 seconds.

The corer is lowered vertically until it impacts with the seabed. At this point the instrument is triggered by a trip as the main coring stem passes through its frame. While pulling the corer out of the sediment a spade swings underneath the sample to prevent loss. When hauled back on board, the spade is under the box."@en ;

The sampler scoops a sediment sample from the top 10cm of the seabed. It brings up virtually un- disturbed, unwashed samples to the surface from any depth. Its specialty is sampling benthic organisms living at or immediately below the water/bottom interface and sediment containing a significant population of non-sessile forms. When the grab touches the bottom, inertia from a self-contained weight releases a catch and helical springs rotate the inner half cylinder by 180 degrees. After turning, the scoop remains closed by the residual torque of the scoop spring. Because the rotation of the bucket is very rapid, its shear strength is far greater than the sediment strength, thus cutting cleanly, particularly in soft clays, muds, silts and sands. Manufactured in 316 stainless steel with a sampling area of 0.042m sq. There is the option of adding a landing table."@en ;

  skos:definition "A custom-designed gas-tight serial water sampler developed by the University of Minnesota. The system is designed for deployment at the seafloor for long-term operation to take time-series fluid samples from deep-sea environments such as cold seeps and hydrothermal vents. The serial sampler is a modular system that is based on independent and identical sampling modules, which are designed to collect six 160 ml gas-tight fluid samples maintained at high pressure to a depth of 4000 meters. With two working modes, the sampler can be deployed either as part of a seafloor cabled observatory for remote control, or as a stand-alone device for autonomous operation. The titanium housing of the system is pressure rated to 6000 m, but the gas-tight samples are only maintained at high pressures to a depth of 4000 m."@en ;

It consists of a cylindro-conical funnel (collecting area of 0.125 m2) with a phenolic composite baffle (cell dia. 9.5 mm) to prevent large objects clogging the system. The trap is fitted with 24 x 250 ml or 24 x 500 ml polypropylen sampling bottles. It is capable of 18 month deployments (24 months with Lithium batteries) and has a sampling interval of 1 minute. It has a maximum operating depth of 1000 m (PETP) or 5000m (Aluminium) or 6000m (Titanium)."@en ;

  skos:definition "The KC Pore-water pressing bench allows pore-water extraction of any kind of sediments, from sediments rich in organic material, to sandy sediments. Sediment cores are segmented and placed in the pressing house, which is closed by means of the handle on top of the house. An over-pressure is applied (fed-in) at the reduction valve and the valves of the houses in operation are opened. The resulting compression of the sediment matrix leads to expelling of the pore-water, which is sampled in containers beneath the pressing house. Operation in a glove bag prevents atmospheric contamination with, for example, oxygen, so anaerobic analysis of the pore-water is possible. The standard cylinders are made from black Polyoxymethylene (POM). However, the cylinders and all accessories are also available as AISI 316 stainless steel for special purposes. The pressing bench consists of 5 pressing houses, each 100 ml. They can hold a maximum sample diameter of 40 mm. The instrument has a maximum operating pressure of 4 bar (400 kPa)."@en ;
