The present invention discloses an automatic pressure-retaining sampling apparatus and method for deep-sea specific layer seawater, relating to the technical field of deep-sea sampling. The sampling apparatus includes a rotation unit configured to drive sampling valves in a multi-sequence sampling filter unit to be opened and closed; the multi-sequence sampling filter unit configured to sample seawater and stabilize plankton; an injection unit configured to inject seawater or stabilization solution into the multi-sequence sampling filter unit; a pressurization unit configured to adjust a pressure of the multi-sequence sampling filter unit; a layer identification unit configured to automatically identify deep-sea target layers; a control unit configured to receive data transmitted from other units and control other units; and an outer frame configured to support other units. According to the present invention, through the coordinated operation of various units, a specific seawater layer can be automatically selected.

The present invention discloses a multi-sequence seawater sampling apparatus and method with thermal insulation and pressure retention, relating to the technical field of marine microorganism sampling. The apparatus includes an outer frame, a flow velocity regulation unit, a rotation unit, a multi-sequence sampling unit, and a control unit. The multi-sequence sampling unit is disposed in the outer frame and includes a plurality of sampling modules. Each of the sampling modules includes a sampling valve, a sampling bottle, a gas phase shutoff valve, and a back pressure valve that are connected in sequence. The plurality of sampling valves are circumferentially distributed at a top of the outer frame, and control ends of all the sampling valves face the rotation unit. The rotation unit is disposed at a center of the top of the outer frame, and an end of the rotation unit abuts against the control end of the sampling valve.

A system and method for capturing ice particles in a vacuum is provided. The system includes a clamshell apparatus. The clamshell includes a stand and a base positioned on top of the stand. A pair of linear actuators is operatively connected to the stand and a lid. The lid is operatively connected to the based movable between an open and closed position. The lid includes a grid with a plurality of apertures. An ultralight gel is positioned within the plurality of apertures and a soft metal sheet positioned behind the grid and the ultralight gel.
