ABSTRACT:
A sampler device for supporting glass slides and/or polymer scrims or pads under water for the collection of plant and animal samples. The device comprises a frame having a top member, a bottom member, and left and right side members. The top and bottom members have a plurality of vertically aligned slots therein for receiving and holding the edges of a plurality of glass slides. The top and bottom members also have generally horizontally extending grooves for mounting a scrim or pad thereon. A guard is pivotally mounted to the frame, and movable between a closed position, in which portions of the guard overlap the ends of the slots in the top and bottom members of the frame, thereby securing the slides in the frame, and an open position in which the guard does not overlap the ends of the slots so that slides can be inserted into and removed from the slots. In the closed position the guard also overlaps the grooves to secure the scrim or pad therein. A lock is provided to retain the guard in its closed position. A mounting bolt extends through the top and bottom of the frame. Eyes on the mounting bolts permit lines to be attached to the bolts for securing the sampler device under water.
