Testing the chemical calibration of Sediment Profile Imagery (SPI) with novel in-situ pore water gel probe techniques: a proof of concept study.

沉积物剖面图像（SPI）最近被用来研究底栖生物群落和沉积物之间的关系。然而，SPI图像还没有真正校准关于沉积物氧化还原和沉积物生物地球化学。这项概念验证研究旨在使用DET和DGT凝胶探针的原位技术对SPI图像进行首次颜色/化学校准，以确定与aRPD（表观氧化还原电位间断）和生物扰动相关的生物背景下的高空间分辨率氧化还原敏感特征。

Sediment Profile Imagery (SPI) has been used recently to look at the relationship between benthic communities and sediment. However the SPI image has not really been calibrated with respect to the sediment redox and sediment biogeochemistry. This proof of concept study aims to use the in-situ technique of DET and DGT gel probes to undertake the first colour/chemical calibration of SPI images in order to determine high-spatial resolution redox sensitive features in a biological context relating to aRPD (apparent redox potential discontinuity) and bioturbation.
