The Shipek Sediment Sampler is designed for sampling 

 unconsolidated sediment, from soft ooze to hard-puck coarse sand. 

 The device is capable of bringing virtually undistrubed, unwashed 

 samples to the surface from any depth. Basically the unit is composed 

 of 2 concentric half cylinders. The inner semi-cylinder, or sample 

 bucket, is rotated at high torque by 2 helically wound external 

 springs. Upon contact with the bottom it is automatically triggered 

 by the inertia of a self-contained weight upon a sear mechanism. 

 At the end of its 180° travel the sample bucket is stopped and held 

 at the closed position by residual spring torque. 



After closure the sample is given optimum protection from 

 washout during the return trip by the cylindrical configuration of 

 the unit. Once on deck, the sample bucket may be disengaged from 

 the rest of the device by releasing two retaining latches at each 

 end of the upper semi-cylinder. The sample is then readily accessible 

 for immediate study or transport to off-site laboratory facilities.
