Ecological study of the Amoco Ecological study of the Amoco Cadiz oil spill : report of the NOAA-CNEXO Joint Scientific Commission ecologicalstudyo00noaa Year: 1982 Because we wanted to compare the marsh at lie Grande with other marshes in the vicinity, we also visited the marsh in the estuary at Kerlavos ca. 5 km from lie Grande (Fig. 2). This marsh contained less Juncus, no Spartina, and was dominated by Puccinellia maritima, Armeria maritima (Mill.) Willd., and Triglochin maritima along with Plantago maritima L., Cochleria officinalis L., Halimione portulacoides and Aster tripolium L. Ther

Willd., and Triglochin maritima along with Plantago maritima L., Cochleria officinalis L., Halimione portulacoides and Aster tripolium L. There was evidence of marsh removal by cleanup operations in the Kerlavos marsh also, but it appeared that the marsh was much less heavily impacted than that at lie Grande. We chose to use this marsh area as a supplemental study site. FIGURE 2. Marsh in estuary at Kerlavos. Areas without vegetation represent sites of marsh removal during Amoco Cadiz oil cleanup operations. PROCEDURE Substrate Substrate samples were taken at the transplant source sites for each species and also at the experimental planting sites each year. These samples were analyzed for elemental concentrations, pH, organic matter, and volume weight by the North Carolina Department of Agriculture Soil Testing Division using their routine methods. 366
