A New Device for Collection of Interstitial Water
from Wetland Sediments
Ned H. Euliss, Jr. and Ronald K. Barnes
Abstract: A sampler for collection of interstitial water from wetland sediments is described. It differs from other sampling devices because it does not have to be filled with solution to facilitate diffusion, it does not have to be removed from the wetland to collect samples, and it can be used to draw repeated samples over time from identical locations. The device facilitates "in situ" measurement of a wide range of abiotic parameters such as electrical conductivity, redox potential, and pH in wetland sediments. The device has application in ecological investigations of sediment-borne wildlife diseases, studies of benthic invertebrates, measurement of nutrient exchange, and other aspects of wetland ecology.
Keywords: Benthos, diffusion-controlled sampler, interstitial water, peeper, pore water, sediment-water interface.
