高分辨率采样对于重建层状、纹层状或非生物扰动沉积物（例如，Bfitt等人，1992年），特别是在沉积速率低（0.1-1毫米/年）的环境中。我们已经开发了一种廉价的方法，以获得高分辨率的样品在毫米厚度的垂直截面的海洋沉积物盒芯。这种技术很容易适应任何实验室环境。该取样装置可以由普通实验室用品容易地构造，并且使用简单。采样速度很快：一个垂直25厘米的箱式岩芯分段可以在大约3小时内采样。
High-resolution sampling is important in reconstructing semiannual to annual faunal, geochemical, and sedimentological records in laminated, varved, or nonbioturbated sediments (e.g., Bfitt et al. 1992), especially in settings characterized by low (0.1-1 mm/yr) sedimentation rates. We have developed an inexpensive method to obtain high-resolution samples at millimeter thickness from a vertical section of a marine sediment box core. This technique is easily adapted to any laboratory environment. The sampling device can be constructed easily of common laboratory supplies and is simple to use. Sampling rates are fast: a 25-cm vertical subsection of a box core can be sampled in about three hours.
