Abstract

During the 1950s and 1960s, F.J.H. Mackereth developed and published plans for a series of pneumatic samplers for lake sediments. Unfortunately, as the equipment was continually evolving during ensuing research, no user manuals, beyond the original publication, had been produced. Over the last few years there have been a few potentially very serious accidents with the 1-metre corer, which has prompted the authors to carry out a risk assessment. This highlighted two weaknesses in the design and its later developments. They can be corrected simply by checking for screw threads that may have been added to the exhaust port on the mini-corer, and by changing the operating procedure. An A4 nine-page user manual is now available from the authors. A small charge ( pound sterling 10 in 1998) will be made to cover handling costs and postage.
