D2 East Transect – 2017

Permanent Site: D2 East Transect; Depth: 12.1 Meters (39.7 Feet); Distance from river mouth: 0.3 Kilometers (0.2 Miles); Pre/Post Dam Removal: 6 years post-dam removal; Lat/Long: 48.15233001,-123.56829403; Site Description: This site is right off the mouth of the river. In 2016 it was actively being buried in sand but this year the substrate was returning to mainly gravel. Brown seaweed was scarce except on the last ten meters of the transect, which were never buried in sand. Six different species of brown seaweeds were observed in this section though only acid kelp Desmarestia were common (2:07, 2:17 seconds). Red seaweeds were present on the entire transect (0:30, 1:14, 2:22 seconds) though not abundant. Invertebrates were absent on the first 20 meters of the transect and only a few were seen on the last ten meters. None are visible on video except numerous dead clam shells (0:23, 0:47 seconds). Woody debris is frequently seen at this site (0:04, 1:58 seconds).
