A new-type sampler using to collect undisturbed samples of shallow drilling sediment core in the coastal wetland geological surveys

摘要

1. Objective The problems associated with traditional equipment for sampling shallow drilling sediment cores include high production cost, short sample preservation time, inability to store in a freezer, and poor resistance to seawater corrosion (Table 1). We developed a sampler with a new design that overcame these problems. The new design worked well in our study and can efficiently support coastal wetland geological surveys.
