Definitions

  • the object of the present invention is, as the title states, to provide both a device and the method for representative sampling of gases and dissolved and particulate matter, that is, in the form of particles, contained in a body of water.
  • the present invention is characterized by the constructive details presented by the device, which make it possible to take representative samples of gases and dissolved and particulate matter contained in a water handle, as well as to achieve a novel closure system characterized by the absence of internal latex or external traction springs resulting in an independence in the closing force between both mouths. Therefore, the present invention is circumscribed within the field of oceanographic technology and instrumentation.
  • Suction pumps are used when large volumes of water are required because these devices can be used even with the ship moving.
  • the suction pumps are limited to the first meters of the water column due to the complexity of their handling and inaccuracy in determining its exact depth at the time of obtaining the samples.
  • the reference device for sampling water at any depth is the oceanographic bottle (such as US50941 13; US 4846004, U S4037477 and US3815422).
  • these devices consist of a cylinder with two end caps, an upper vent plug and a water outlet at the bottom of the bottle.
  • gases and dissolved matter have a Lagrangian behavior, that is, they move with the body of water.
  • particulate matter is operationally divided into two categories: suspended and settling. Suspended particulate matter has a dynamic similar to gases and dissolved matter moving within the body of water. On the contrary, the sediment particulate matter has vertical sedimentation rates that infer a totally different dynamic behavior.
  • the sedimentation rates of the particles in the ocean are determined by the differences in density between them and the surrounding water. Recent results show that sedimentation rates of particles in the ocean vary between ⁇ 0.7 m / d and> 980 m / d (Alonso-González et al., 2010). Assuming an average velocity of the material that sediments in the ocean of 100 m / d, the particles collected by the current oceanographic bottles are deposited at the bottom of them in about 14 minutes. However, the sampling profiles usually last an average of 2-4 hours, depending on the depth, so that all the sedimentation material is at the bottom of the bottle when it reaches the surface.
  • the problem is that, according to the established protocol, the gases (O2, CO2, etc.,) and dissolved material (pH, Alkalinity, etc.,) are first sampled, extracting, in the current devices, all the particulate material that has settled during this process. This implies that when the parameters associated with the sedimentation material are subsequently sampled (particulate organic matena, phytoplankton, zooplankton, etc.), they are being drastically underestimated.

  • the operation of the device of the present invention is based on the channeling of the flow of water through the body caused by the rise of the oceanographic rosette until the operator decides to close the device to the selected depth by remotely activating the firing system. of bottles featuring oceanographic rosettes.
  • the torsion spring installed at both ends moves the hemispherical head piston towards the device closing while the compression mechanism acts to seal it against the tonca.

  • the procedure associated with the device of the present invention refers to the manner of proceeding in the collection of water samples from the device of the present invention.
  • the sampling procedure is the one established internationally, water samples are first taken for the analysis of gases and dissolved matenal and subsequently of sediment particulate material. However, each sample will be taken from the appropriate water outlet to its end; thus the samples for analysis of dissolved gases and dissolved and suspended matter will be taken from the outlet located at the middle level of the body, while samples for measurements of sediment particulate matter will be taken from the outlet located in the lower part of the body.
