. Ecological study of the Amoco Cadiz oil spill : report of the NOAA-CNEXO Joint Scientific Commission. Amoco Cadiz (Ship); Oil spills -- Environmental aspects France; Oil spills -- Environmental aspects North Atlantic Ocean. 1979 Plantings Based on our preliminary plantings made in December 1978 and the nutrient analysis of initial substrate samples, we established 9 experimental plantings in May 1979, using primarily Puccinellia maritima (Fig. 3), to a lesser extent Juncus maritimus (Fig. 4), and to a lesser extent still because transplants were not locally abundant, Spartina maritima (Fig.

Amoco Cadiz (Ship); Oil spills -- Environmental aspects France; Oil spills -- Environmental aspects North Atlantic Ocean. 1979 Plantings Based on our preliminary plantings made in December 1978 and the nutrient analysis of initial substrate samples, we established 9 experimental plantings in May 1979, using primarily Puccinellia maritima (Fig. 3), to a lesser extent Juncus maritimus (Fig. 4), and to a lesser extent still because transplants were not locally abundant, Spartina maritima (Fig. 5). These experimental plantings were designed to determine transplant response to conventional ammonium sulfate + concentrated superphosphate and slow release (Mag Amp and Osmocote) fertilizer materials at different rates over a wide range of tidal elevations. All transplants were taken from the natural marshes at lie Grande and Kerlavos. Digging of transplants was confined to small areas along narrow drainageways (Fig. 6) and protected sites so as to impact the marsh as little as possible. Half of the 2900 May transplants were plugs (10 to 15 cm deep cores from 5 to 7 cm in diameter composed of root material with attached substrate) and half were sprigs (root material only) (Figs. 7, 8, 9). Holes for the transplants were made with a diameter soil auger (Fig. 10). Transplants were spaced m apart and the appropriate amount of fertilizer material was placed into the transplant hole prior to insertion of the transplant (Fig. 11). Planting was conducted just prior to the spring tide cycle so that transplants would be flooded shortly after FIGURE 3. Puccinellia maritima. 367.
