Base provided with a water level and two levelling screws. Net weight approx. 1 kg Water Samplers LIMNOS Water Sampler The Water Sampler LIMNOS is an approved and uncomplicated instrument to take water samples up to 30 m depth. The LIMNOS Water Sampler consists of the holder device made of PVC and exchangeable 1000 ml glass bottles as sampling vessels. The LIMNOS Water Sampler is attached to a wire and lowered into the water in closed condition in order to prevent sample contamination by surface water. The sampler is opened by means of a messenger upon reaching the desired water depth. When the messenger hits the anvil, the silicone tubings spring up to allow water to move in and the air to leave the bottle. For investigations of the sample, the glass bottles are taken from the holder device, so that the sample cannot be falsified by pouring from one vessel to another. 436 140 LIMNOS Water Sampler for use up to 30 m water depth, with two glass bottles 1000 ml each and Plastic Covered Messenger 436 145 Glass Bottles 1000 ml for use up to 30 m water depth, (package of 10 pcs.) 440 002 Plastic Covered Messenger, 500 g, up to 6 mm rope diameter MICROS Water Sampler The Water Sampler MICROS is an uncomplicated and approved instrument to take samples up to 100 metres water depth. The slim shape allows the sampling from tubes as small as 80 mm diameter. Special feature of this water sampler is the possibility to sterilize the instrument for sampling (auto-clavetreatment). The MICROS Water Sampler consists of a frame made of stainless steel, a bottle holder of Teflon with silicone tubings and an exchangeable glass bottle with 500 ml capacity as sampling vessel. The MICROS Water Sampler is attached to a wire and lowered into the water in closed condition (with silicone tubings snapped off) in order to prevent sample contamination by surface water. The sampler is opened by means of a messenger upon reaching the desired water depth. When the messenger hits the anvil, the silicone tubings spring up to allow water to move in and the air to leave the bottle. The glass bottle can be taken from the holder device, so that the sample will not be falsified by pouring from one vessel to another. 436 160 MICROS Water Sampler for use up to 100 m water depth, with one glass bottle 500 ml and Plastic Covered Messenger 436 165 Glass Bottles 500 ml for use up to 100 m water depth (package of 3 pcs.) 440 002 Plastic Covered Messenger, 500 g, up to 6 mm rope dia. 3 Water Samplers Standard Water Sampler acc. to Ruttner With this handy and versatile apparatus, water samples can be taken from any desired depth. The closing mechanism of the sampler has proved itself to be most satisfactory over many years; the water sampler is of simple and practical design and guarantees reliable results. The Standard Water Sampler, still open, is lowered by rope into the water. Upon reaching the desired depth, the messenger is let down on the rope. When it strikes the Standard Water Sampler, the closing mechanism is released and the lids of the sampling tube close. A thermometer ranging from -2° to +30°C, indicates the temperature of the sample; the temperature can easily be read through the plastic tube of the sampler. The water sample can be drawn off through the discharge cock in the lower lid for the various analyses. 436 131 Standard Water Sampler acc. to Ruttner, capacity approx. 1000 ml Dimensions: length 56 cm, Ø 10 cm, weight 4.5 kg 436 132 ditto, but capacity approx. 2000 ml Dimensions: length 75 cm, Ø 10 cm, weight 5 kg 436 136 Spare Thermometer measuring range -2° to +30° C, divided in 0.2° C (set of 3 pcs.) 440 000 Spare Messenger made of stainless steel. With 6 mm bore. Weight 400 g Industrial Water Sampler The Industrial Water Sampler is an improved version of the Standard Water Sampler and was developed to comply with the demands for more exact analytical tests. The inside of the sampling tube is metalfree and thus tests for the determination of trace elements are possible. A thermometer is not built-in. 4 436 152 Industrial Water Sampler, capacity approx. 1000 ml. Dimensions: length 60 cm, Ø 8 cm, weight 2 kg 440 000 Spare Messenger made of stainless steel. With 6 mm bore, weight 400 g Water Samplers The TPN Transparent Plastic Nansen Water Sampler combines the most advanced technological procedures with the traditional methods of construction. This instrument meets the highest requirements in today´s Oceanography. It has been tested the world over under various conditions and approved as very satisfactory on board the German Oceanographic Research Vessel "Meteor". Outstanding features: transparent sampling tube of shockresistant polycarbonate, large circular inlet, greasefree ball valves with Teflon-seals, capacity 1.7 litre, graduated sampling tube, light weight 3 kg in the air, 1.5 kg in the water. The outer measurements do not exceed those of the traditional metallic Nansen Bottle. Easy to service, as all component parts readily replaceable. 436 201 TPN Water Sampler, capacity 1.7 litre, incl. messenger 436 202 Triple Thermometer Tube for three reversing thermometers 436 205 Storage Rack for wall mounting, stainless steel 440 000 Spare Messenger 400 g, made of stainless steel, up to 6 mm rope diameter MERCOS Water Sampler The MERCOS Water Sampler is an approved and uncomplicated instrument to take water samples for ultratrace metal analysis as well as for microbiological investigations. The MERCOS Sampler consists of the holder device and exchangeable 500 ml Teflon Bottles as sampling vessels which can be used up to 30 m water depth. All fittings are made of titanium. The MERCOS Sampler is attached to a plastic-coated steel hydrographic wire and lowered into the water in closed configuration in order to prevent sample contamination by surface water. The sampler is opened by means of a plastic-covered messenger upon reaching the desired water depth. When the messenger hits the anvil, the silicone tubings spring up to allow water to move in and the air to leave the bottle. In case of serial operation, a second messenger for release of the next sampler is given free at the same time. For the determination of tracer elements in seawater the system Sampling Bottle=Storage Bottle = Reaction Vessel is realized, so that the samples cannot be falsified by pouring from one vessel to another. In order to sterilize the bottles for microbiological investigations the Teflon Bottles incl. coupling pieces and silicone tubings can easily be taken from the holder. 436 252 MERCOS Water Sampler, with two Teflon Bottles 500 ml and Plastic Covered Messenger 436 254 MERCOS Water Sampler, with four Teflon Bottles 500 ml and Plastic Covered Messenger 436 255 Teflon Bottle, 500 ml, for 30 m water depth 440 002 Plastic Covered Messenger, 500 g, up to 6 mm rope diameter 5 Water Samplers Plastic Water Sampler PWS The Plastic Water Sampler PWS features all plastic (PVC) constructions with a free flushing design by large inlets.The sampling tube is completely metal-free. The end stoppers of the sampler are connected by a strong latex rubber tubing. A messenger dropped down the wire from the surface releases the end stoppers for closure. The PWS can be used as a series water sampler and is designed to release a second messenger below the sampler in order to actuate a series of samplers along the wire. When operated as a single instrument on the wire, we recommend to use a Centered Mounting Rack which holds the sampler in a vertical position. Water may be drained from the sampler by opening the stop cock at the lower end. 436 300 436 302 436 305 436 315 436 325 Plastic Water Sampler PWS, incl. messenger capacity 1.7 litre capacity 2.5 litres capacity 5.0 litres capacity 10.0 litres capacity 30.0 litres Free Flow Water Sampler The Free Flow Water Sampler is an innovative design which has been developped in co-operation with the Institut für Ostseeforschung, Warnemünde (Germany). An outstanding feature of the Free Flow Water Sampler is the free-flushing construction of the sampling tube where no cone or ball-valve hinders the flow of the water through the tube. The Free Flow Water Sampler is made of plastic (PVC) and the sampling tube is completely metal-free. The end stoppers are connected by a strong latex rubber tubing. Upon reaching the desired water depth the sampler is closed by a messenger dropped down the wire. The Free Flow Water Sampler can also be used in nearly all multi sampler systems (Multi Water Sampler, Rosette, Carousel). The free-flushing design avoids the retarding effect, so that the sample corresponds to the parallel measured data of a CTD Probe. A second messenger below the sampler can be released in order to actuate a series of samplers along the wire. When operated as a single instrument on the wire, we recommend to use a Centered Mounting Rack which holds the sampler in a vertical position. Water may be drained from the sampler by opening the stop cock at the lower end. 436 342 436 343 436 345 436 380 436 385 436 390 436 395 440 000 6 Free Flow Water Sampler, incl. messenger capacity 2.5 litres capacity 5.0 litres capacity 10.0 litres Accessories Centered Mounting Rack for PWS and Free Flow Water Sampler 1.0 - 2.5 litres ditto, for 5.0 litres version ditto, for 10.0 litres version ditto, for 30.0 litres version Spare Messenger, 400 g, with 6 mm bore Water Samplers Universal Water Sampler This Universal Water Sampler has been developed as a combination of many standard instruments, incorporating their assets and eliminating their shortcomings. A new kind of lid attachment and tightening guarantee it to be absolutely leak-proof. Outlet and air-inlet faucets facilitate easy removal of the sample. The lids are arrested automatically in an open position and do not hinder the free flow of water through the completely open tube. This prevents clogging or bobbing and guarantees that the water is taken from the exact sampling depth desired. When used as a single instrument on the wire, we recommend to use a Centered Mounting Rack which holds the sampler in a vertical position. All inside parts are completely metal free, so that the water sample is uncontaminated and suitable even for electrolytic tests. The Universal Water Sampler can be used as a series water sampler and is designed to release a second messenger down the wire below the sampler in order to actuate a series of samplers along the wire. When operated as a single instrument on the wire, we recommend to use a Centered Mounting Rack which holds the sampler in a vertical position. If desired, the Universal Water Sampler can be delivered as a Plankton Sampler with a transparent plastic tube instead of the non-transparent tube. 436 403 Universal Water Sampler, capacity 3.5 litres, with transparent plastic tube and a clamping device for a cable with a maximum thickness of 6 mm ( 1/4").

The Horizontal Water Sampler can be attached to any line or wire up to 6 mm ( 1/4 ") in diameter. Water samples can be taken from any desired depth. When lowered for sampling, the sampling tube is kept completely open, allowing the water with its sediment and silt to flow through it undisturbed. The cylinder is held parallel to the current by a stabilizing rudder. The lids are arrested in an open position and do not hinder the free flow of water through the completely open sampling tube until released by a messenger. An approved lid attachment and tightening guarantee the sampler to be absolutely leak-proof. The sampling tube is metal free, so that the water sample is uncontaminated. Outlet and air-inlet faucets facilitate the easy removal of the sample. A messenger-operated release device closes the sampler when the desired sampling depth has been reached. The water sample can subsequently be examined in the laboratory to determine the weight, particle size of the sediment, mineral components etc. The non-transparent sampling tube prevents light from reaching the trapped organisms, as required in productivity studies. The Horizontal Water Sampler can also be delivered with a clear transparent plastic tube which allows visual examination of the contents. 436 510 Horizontal Water Sampler, with non-transparent plastic tube, capacity 2.0 litres, with messenger, net weight 10 kg 436 520 Horizontal Water Sampler, with transparent plastic tube, capacity 2.0 litres, with messenger, net weight 10 kg 440 000 Spare Messenger, 400g stainless steel, up to 6 mm rope diameter Oil Sampler acc. to Schomaker The Oil Sampler acc.to Schomaker is designed to collect an oil layer which contaminates the water surface. This instrument has been developed by Deutsches Hydrografisches Institut (DHI) and, for the first time, allows to keep the part of water in such samples small and to collect sufficient oil for the determination. The operation and handling of the instrument is quite simple: The sampler is thrown onto the water surface and held by a Nylon line. The floating bodies bring the oil sampler into the right position so that the oil sample flows in a layer of only a few millimeters thickness through the inlet funnel into the glass bottle. The collected sample has a volume of approx. 150 ml. The instrument is pulled out of the water by means of the Nylon line, the glass bottle is screwed off and the sampling dates are written onto the label. 8 436 550 Oil Sampler acc. to Schomaker 436 555 Spare Glass Bottles (package of 10 pcs.) Automatic Water Sampler Automatic Water Sampler Multi-Limnos The Water Sampler Multi-Limnos has been designed to take automatically up to 10 water samples in depths up to 30 metres. The system is equipped with 10 Duran glass bottles of 1 litre capacity each. The bottles are screwed into a Limnos head and attached to the base plate. When the system is lowered to the desired water depth all bottles are closed. They are opened one after the other according to the preselected time intervals. When the bottles are filled with water, they are closed automatically by integrated ball valves. The bottom anchoring system offers the possibility to choose the water depth and, if required, change the depth with each operation. The system can be handled by one person. As marking at the water surface a float in the size of a handball is used. The state-of-the-art electronics, optimized in power consumption, are designed for ambient temperatures from -40°C up to +85°C. As option a conventional suspension for operation of the instrument from a boat is available. 436 980 Automatic Water Sampler Multi-Limnos, Economy Version with 10 Duran glass bottles 1 litre, incl. 6 floats and anchorage (without bottom weight).

Weight 5 kg ditto, but lead-weighted to enable greater depths to be reached. Weight approx. 10 kg Spare Messenger for releasing the closing mechanism, with 6 mm bore. Weight 400 g Special Closing Mechanism for Bottom Samplers acc. to Ekman-Birge and Lenz To extract samples in shallow waters with the Bottom Samplers acc. to Ekman-Birge and Lenz this special closing mechanism can be used to push the samplers into the water bed and then release the closing mechanism. The receiving aperture for the rod tripper is 20 mm Ø. Special Closing Mechanism. Weight 400 g Bottom Sampler acc. to Van Veen With the Bottom Sampler acc. to Van Veen samples can be extracted from any desired depth. While it is being lowered, both levers are locked wide apart whereby the jaws are open. Upon making contact with the water bed, the locking mechanism is released and when the rope is pulled taut to raise the sampler, the jaws close. Bottom Sampler acc. to Van Veen, small model with a surface of 250 cm2, made of stainless steel. Overall dimensions approx. 20 x 30 x 60 (cm). Weight approx. 5.5 kg ditto, large model with a surface of 1000 cm 2, made of stainless steel. Overall dimensions approx. 35 x 42 x 90 (cm). Weight approx. 25 kg Sediment Sieve Net For sieving samples taken by Bottom Samplers. Consisting of a galvanized steel frame 40 x 25 (cm); a net bag of synthetic material with 250 microns mesh size (other mesh sizes available on request) and two carrying ropes of Nylon. Sediment Corer Sediment Corer Designed to obtain samples from soft, sandy and medium-hard bottoms. The Sediment Corer is easy to handle and can be operated manually with a push rod in shallow waters as well as in greater water depths by using a rope. The exchangeable core tube has a length of 600 mm and an inner diameter of 72 mm. When the corer is dropped into the water, the plastic valve flap on the top of the transparent plexiglass tube is held open and ensures free flow of the water through the corer tube. The corer is pushed by hand into the sediment (using the offered transverse bar or a rod) or penetrates into the bottom by its own weight (using a rope or wire). When the desired sample has been taken and the corer is lifted out of the sediment, the water pressure onto the valve flap closes the tube during hieving. Upward movement creates a vacuum, so that the sediment sample is retained in the tube and cannot get lost as the corer is retrieved. After raising the corer out of the water, the supplied piston is put into the lower end of the tube. The cage with rope stirrup is taken off and the tube with the core sample is placed onto the piston. When the tube is now pressed onto the piston, the core sample can be removed for examination. 437 400 Sediment Corer incl. transparent core tube, net weight approx. 6 kg 437 405 Replacement Core Tube, transparent, 600 mm long x 70 mm i.d. 437 406 Special Core Tube, made of stainless steel, 600 mm long x 70 mm i.d. 437 410 Transverse Bar to be fixed onto the stirrup for sampling by hand Hand Net acc. to Böttger Small rectangular net with an opening of 25 x 25 (cm). Net bag 35 cm deep with a mesh size of 500 microns (other mesh sizes available upon request). The net frame is made of stainless steel and the handle joint is prepared to receive the Telescopic Rod (Cat. No. 438 305). 438 310 Hand Net acc.to Böttger 13 Plankton Nets Plankton Nets acc. to Apstein The Plankton Nets acc. to Apstein, used in limnological investigations, are manufactured in various shapes® and sizes. MOnyl synthetic tissue is employed as sieve material. Plastic (ABS) Cowls are used for quantitative nets. A minimum of service is needed since all metal parts are protected against corrosion. Rotting of the textile, as is usual with silk gauze, is impossible. The mesh ® of this MOnyl synthetic tissue does not change by swelling of the threads, as is the case with silk.

The Hamburg Plankton Net is equipped with a net bag of MOnyl® with 500 micron mesh size. The overall length of the net is 10 metres. When the Hamburg Plankton Net is towed, the drag to the fine-meshed net is supported by a coarsemeshed covering net and 5 Nylon ropes along the net. For the security of the Hamburg Plankton Net a predetermined breaking-point has been constructed into the bridle, which makes the net collaps when the dynamic pressure becomes too strong. The Hamburg Plankton Net is beeing towed at a speed of 0.5 up to 4 knots. It can be used in each desired depth. Even under wind forces 7- 8 it has been operated successfully. th th On the 44 and 45 research cruise of the German Research Vessel ”Walter Herwig” to Iceland the Hamburg Plankton Net was used with excellent results. So in hauls of 0.5 to 2 hours 14 - 35 kgs of pure plankton were collected. These quantities have been platefrosted and are sufficient for radiochemical analysis. In only 16 hauls of the Hamburg Plankton Net more than 200 kgs frosted plankton plates have been collected.

For horizontal collections the MultiNet® is used with a V-Fin Depth Depressor, to carry out vertical collections, a stainless steel support is securely attached to the bucket holder and enables a quick lowering to depth. Equipped with 5 resp. 9 net bags the MultiNet® can be delivered in 3 sizes (apertures) : Mini (0.125 m2), Midi (0.25 m2) and Maxi (0.5 m2). Operation: In its initial position the MultiNet® is brought to water with all net bags closed. The water flows freely through the frame allowing to lower it to the greatest desired depth with high paying out speed where the first net bag is opened by push button control from the Deck Command Unit. At the end of the desired period of horizontal collection resp. after passing the desired depth interval in case of vertical operation, the first net bag is closed by a second command. The second net is opened simultaneously. This procedure is repeated for the remaining net bags, while the Deck Command Unit indicates the number of the active net bag. During operations of Mini and Midi versions the last net (No. 5) remains open, it collects plankton from the smallest desired depth up to the water surface. During operations of the Maxi version the last net (No. 9) can be closed before reaching the water surface. The system consists of a mains powered Deck Command Unit and a stainless steel frame with canvas part to which 5 (9) net bags are attached by means of zip fasteners. The net bags are opened and closed by means of an arrangement of levers which are triggered by a battery powered Motor Unit. The commands for actuation of the net bags are given via single or multi-conductor cable (not included in our scope of delivery) between the Underwater Unit and the Deck Command Unit. A wide selection of mesh sizes for the net bags is available to meet the requirements of all standard and non-standard applications. For common horizontal collections a mesh size of 300 microns (mesh sizes from 100 to 500 microns available ) is recommended, for vertical collections mesh sizes from 55 to 500 micron are applicable. An integrated Pressure Sensor (measuring range according to customer’s requirements) allows continuous supervision of the actual operating depth which is indicated together with all relevant system data at the LCD-display of the Deck Command Unit. Two Electronic Flow Meters (option) with automatic angle compensation can be mounted to the Underwater Unit: one inside the opening of the Underwater Unit for the determination of the amount of water passing through the opened nets, one outside the opening for the determination of clogging effects. Options: • Offline-Set In case that a conducting cable is not available on board of the vessel an Offline-Set is available which enables to pre-programme the required sampling depths via personal computer. With the Offline-Set the activation of the net bags is carried out automatically according to the pre-selected depth intervals. All measuring data are stored inside the Offline-Set during the operation and can be read by a PC when the MultiNet® is back on board. • CT-Set Together with the optional CT-Set the system offers the full capability of a state-of-the-art oceanographic Multi Parameter Probe. The CT-Set consists of one conductivity sensor, one temperature sensor and an additional electronics board which are completely integrated into the Motor Unit of the MultiNet®. From the CTD data the system computes salinity, density and sound velocity according to UNESCO formulas. • Additional sensors of various parameters • Data memory up to 4 MByte • Battery powered Hand-Terminal, special version for online operations to replace the mains operated Deck Command Unit when no mains supply is available. • Special version for operational depths down to 6000 metres Features Horizontal and vertical operations Easy handling Bi-directional communication Standard depth range 3000 metres Long distance FSK-telemetry (> 10000m) Low power consumption Battery operated Underwater Unit, max. voltage of 5 V at the conductor cable • EC-conformity (CE) EN 50081-1, EN 50082-1 • Electronics operate from -40°C up to +85°C • • • • • • • 20 Ordering Information 438 120 MultiNet® Type Mini consisting of: a.

The Visibility Disc is equipped with a rope of 3 metres length. There are 10 marks in distances of 200 mm on the first 2 metres above the disc. The Visibility Disc is lowered into the water and reading of the depth is made by means of the marks at the rope when the disc is no longer visible in the water. It is lowered another 0.5 m and then heaved slowly again. The second reading is made when the disc becomes discernible. Now the arithmetic mean from both readings has to be made to determine the visibility depth.

The 6 digit LCD display shows the towing distance in metres. Thus the water volume can be easily calculated by multiplication of the measured value (metres) with the opening area of the plankton net. Due to the indisturbed flow of the impeller from the front a high measuring accuracy even in case of low water velocities (from 0.1 m/s) is guaranteed. A flow from the backside does not influence the measuring value. The counter can be reset by a turning knob to 0. The instrument is maintenance-free. The only movable part is the exchangeable impeller. The built-in Lithium battery allows a continuous operation of 5 years.

By means of the Dipping Bar acc. to Jens the current speeds of streams, channels and small rivers up to 60 cm water depth can be measured. The Dipping Bar has, besides its sturdy construction and simple operation, the advantage that with one single and short measurement the average current of a vertical measuring line can be determined. Therefore, the quantity of water of a discharge section can be ascertained quickly and secure. The Dipping Bar acc. to Jens is constructed after the principle of a torque balance; it takes up all individual current speeds of the vertical measuring line integratingly. The powers operating on the measuring rod produce a turning moment and distract the measuring rod away from the vertical line. By means of an adjustable weight rod a counter turning moment is produced so far that the measuring rod is brought back into the vertical line. From the division on the weight rod there can be read the figure which is equivalent to the adjusted turning moment. This figure and the corresponding immersion depth are typed into the programmed calculator. The display indicates the current speed of the actual measuring point in cm/sec. Additionally, by linear approximation covering some measuring points over a section of a running water, the calculator delivers the discharge quantity of the complete section in m3/sec. 28 445 600 Dipping Bar acc. to Jens for current speeds up to 150 cm/sec.

The ability to measure this process is of great importance when accessing marine pelagic systems. In practice the most sensitive method for measurements of photosynthesis is to measure the absorption of carbon dioxide. The high sensitivity of carbon dioxide absorption measurements allows the use of this method under all circumstances, at low and very high algal concentrations and under low light and temperature conditions. Based on the 14C method, using the absorption of the radio-active 14C isotope of carbon (SteemannNielsen, 1952), the ICES Incubator is the ICES standard incubator for phytoplankton primary production measurements. The incubator shown here has been mainly developed for monitoring purposes. It should be used preferentially for water samples taken from a mixed water layer which has a fixed temperature. For calculations of productivity per square meter additional data on vertical water attenuation are needed as well as daily irradiance values. Additional measurements of the amount of phytoplankton (based on chlorophyll-a concentration measurements) should be carried out for interpretation purposes. The ICES Incubator consists of an illuminated transparent plexiglass tank incorporating a turning wheel on which 12 experimental bottles can be clamped. The tank is filled with water which is set in motion by an adjustable circulating pump. Thus the turning wheel is set in rotation at speeds up to 10 rpm with the experimental bottles acting as paddles. Tank connections for a second water circulation allow for 450 000 temperature adjustments of the water by using external tempering equipment. The 12 experimental bottles of 50 ml capacity each have different optical coatings, so that each bottle has individual transmission rates and thus generating a number of 12 different irradiance (or light intensity) levels. The illumination unit is equipped with 10 fluorescent tubes with a wave spectrum according to ICES specifications, each one of which can be switched individually. For higher irradiance levels a second illumination unit can be mounted onto the ground plate of the ICES Incubator.
