| 520 | |a"A very important aspect of any limnological study of any lake is the geology of the lake. In order to determine the past history, the modern baseline as to the condition of the lake, knowledge of the activities within the sediment must be known for future studies. In order to obtain this knowledge, proper and undisturbed bottom sediment samples must be collected, analyzed and sometimes even stored for future reference and comparison. As a support service, Technical Operations keep a well-stocked supply of numerous types of coring and bottom grab samplers. The scientific sampling equipment ranges from the very light samplers used from small boats to the very large, requiring heavy cranes and ships. In the following report, numerous most commonly used samplers and their uses are described. Application and types of sediment each sampler will collect accompanies the samplers' descriptions"--Introduction, page 1. |
