A1 East Transect – 2017

Permanent Site: A1 East Transect; Depth: 7.7 Meters (25.4 Feet); Distance from river mouth: 1.8 Kilometers (1.1 Miles) West; Pre/Post Dam Removal: 6 years post-dam removal; Lat/Long: 48.13870775, -123.5855312; Site Description: Transect is in eastern part of Freshwater Bay. Sediment is primarily sand/sandy mud. Previous small boulders appear to still be buried. The sand on the entire transect is covered in a thin, brown layer of diatoms (small, unicellular microseaweed). Seaweeds are typically scarce at this site but this year small bull kelp (Nereocystis luetkeana) were present (0:15 seconds) as well as a single, flat bladed Desmarestia (0:23 seconds) and long, flowing sheets of red seaweed (0:29, 0:55 seconds). The patch of eelgrass (Zostera marina) seen in 2011-2012 has not returned. Three species of crabs are seen on this video: graceful kelp crab Pugettia gracilis (0:23 seconds), graceful crab Metacarcinus gracilis (1:09 seconds), and Dungeness crab Metacarcinus magister (1:45 seconds).
