The primary goal of the present study, which was conducted by the National Marine Fisheries Service, in OctoberlNovember 1995 and June 1996, was to assess benthic invertebrate communities and sediment characteristics at stations west and north of the Columbia River entrance. Clams, worms, oysters and mussels are examples of benthic organisms. Triplicate u.S. Anny Corps of Engineers Portland District P.O. The final step of the evaluation process is to combine the three LOE category classifications to determine the station assessment category. The data from each LOE are then summarized, interpreted using multiple indices, and integrated in Steps 2-4 in order to determine a LOE condition category. Infauna samples were rinsed with filtered s eawater by AECOM over a 0.5-mm-mesh sieve and transferred to 80% ETOH for sorting and storage.

The epifauna are representing the benthic organisms living on the surface of the bottom of the water body, while the infauna is represented with the benthic organisms living few centimeters beyond the bottom, mostly in subtidal zone. Just like temperature, pressure also varies across the benthic zone. Example sentences with the word infauna.infauna example sentences.

The anoxic nature of the sediments in which mangroves grow is likely to influence the dissolved oxygen (DO) dynamics of water in mangrove forests, and in turn influence the way benthic organisms utilize mangrove habitats. To facilitate the sorting process, all samples were stained in a saturated alcoholic solution of Rose B engal at least overnight, but no longer than 48 h. L. Emmett .
