Nicoya Peninsula sediment core field work (2010)

VIMS students shown collecting bog and marsh samples on the Costa Rica Nicoya peninsula. The samples will be dated to help understand the palaeoseismicity of the region. In the image, a Russian peat corer is used to sample peat and other woody plant material. The coring chamber - the wide metal part visible near the water - is pushed into the subsurface. Extension rods, as shown here, can be used to push the corer deeper. When the target depth is reached, a T-handle is used to rotate the entire core assembly 180 degrees. In doing so, a sharp metal edge cuts longitudinally to capture an undisturbed sample of material. The corer is then pulled back up to recover the sample. Image courtesy of Jim Spotila.
