The location of Ucluelet BC is shown on the following map:
he results for the Ucluelet sample are reported decay corrected to the date of sampling (February 19, 2015). A good check on the quality of the data is to decay correct to the date of peak Fukushima input to the coastal ocean off Japan which is roughly April 6, 2011. These decay corrected values for 137Cs and 134Cs are 6.4 and 5.2 Bq m-3 respectively. As we know that pre-Fukushima levels of 137Cs were about 1.2 Bq m-3 owing largely to atmospheric weapons testing fallout in the 20th century the Bq m-3 this shows the Fukushima 137Cs/134Cs input ratio was equal to 1 and is consistent with previous marine monitoring work.
Monitoring of seawater and marine biota contamination will continue with the help of citizen scientist volunteers in the coming months and years to determine the impact of the Fukushima disaster along the coast of North America. Those interested should consult the following monitoring programs:
Results will be posted here as they become available.
