This is an aerial view of the flume marsh (Sep 96, courtesy Ron Kneib), looking south from the edge of the upper Duplin River toward the mainland. Several pieces of important saltmarsh- ecological research have been done here: i) examination of rates of import/export of organic carbon by Alice Chalmers and Dick Wiegert (early 80s); ii) examination of fates of water-column bacteria in flooding tidal waters by Christiane Krambeck and me (early 90s); iii) reexamination of rates of cordgrass productivity and response to nitrogen subsidy by Ting Dai and Dick Wiegert (late 90s). I am currently using this as my "Upper Duplin" site for my examination of seasonal/interannual patterns of change in living-fungal standing crops and productivities in naturally decaying smooth cordgrass (Spartina alterniflora) and black needlerush (Juncus roemerianus). The dark green/gray patches in the marsh near the mainland are needlerush zones. The flume itself is no longer being maintained, and has mostly collapsed; you can just make out the remnants of the boardwalks running from the still-functional Duplin-monitoring station south to the mainland.
