已经研制和测试了一种深海沉积物间隙沃茨现场取样装置。采样器在沉积物中1.5米深度收集一系列样品，从而可以准确地描绘孔隙沃茨中存在的化学梯度。在北大西洋收集的样品表明，在采样的沉积物中存在显着的梯度的K+和Ca2+。在爱尔兰和马萨诸塞州的科德角之间取样的间隙溶液的特征是K+的贫化和Ca 2+的富集。
A device for sampling the interstitial waters of deep-sea sediments in situ has been developed and tested. The sampler collects a series of samples over a depth of 1.5 meters in the sediment and thus makes possible the accurate delineation of chemical gradients existing in the pore waters. Samples collected in the North Atlantic indicate that significant gradients of K+ and Ca2+ exist in the sediments sampled. Interstitial solutions sampled between Ireland and Cape Cod, Massachusetts, are characterized by the depletion of K+ and the enrichment of Ca2+.
