in Hythe samples on both days. At all sites the chlorophyll a content significantly
declined with depth, and in all cases > 40 % of the total chlorophyll a in the
surface mm was found in the top 400 ýtm. See Table 6.6 for summary.
Overall, there was no significant differences in the chlorophyll a contents
between years for either Arlesford Creek (H = 0.9, df = 1, p=0.342) or the
Hythe (H = 0.24, df = 1, p=0.623).

The water content significantly declined over the course of day 1 (1999)
in cores from Arlesford Creek (H=31.45, df = 7, p
