More Citizen Science Sampling Kits Being Shipped Out

By Jay T. Cullen

@JayTCullen and @FukushimaInFORM

Shown below are sampling kits that will ship out today for our citizen science volunteers in Tofino, Winter Harbour, Hadia Gwaii – Sandspit and Port Hardy BC.  Staged for pick up are Lax Kw’alaams, Prince Rupert, Powell River and Haida Gwaii – Masset.  Results of seawater monitoring for Fukushima derived radioactivity will be made public as they are available.

Looking For Fukushima Contamination in Mushrooms and Soil of Western North America

By Jay T. Cullen

Chanterelle Cantharellus cibarius
 

The purpose of this diary is to report results from a recently published, peer reviewed study (behind paywall) examining the degree of Fukushima contamination in fungi and soil of western North America. The diary is the most recent contribution to an ongoing series which aims to provide evidence from scientific studies assessing the impact of the Fukushima Daiichi disaster on the environment and the health of residents of North America. Trappe and colleagues measured the activity of cesium isotopes (134-Cs half life ~ 2 years; 137-Cs half life ~30 years) in wild mushrooms, soil and leaf litter of the west coast from California up to Vancouver Island. The conclusions of the study were as follows:

  1. No activity measurements exceeded levels thought to impact human health
  2. 137-Cs activity increased in fungi and soil towards the north
  3. 134-Cs increased to the south in leaf litter
  4. Chanterelles did not significantly bioconcentrate Cs isotopes
  5. 137-Cs and 134-Cs activities were highly variable from sample to sample
  6. 137-Cs levels largely reflected non-Fukushima sources from either atmospheric weapons tests in the last century or the Chernobyl disaster in 1986

How do we process seawater samples?

By Jay T. Cullen

The InFORM team is busy processing samples returned to us from our citizen scientist volunteers who collected seawater at various locations in November.  When we receive the seawater we first filter it through a 1 micron ( 1 micron = 10-6 meter) cartridge to remove larger debris and sediments that might be present.

Testing the waters for Fukushima

Story by John Gleeson

Despite the doom porn circulating on the Internet, there has been no radiation from Fukushima detected yet along the Salish Sea – or if you prefer, the Strait of Georgia.

That’s according to Jay Cullen, a chemical oceanographer at the University of Victoria.

December Citizen Seawater Sampling by SurfRider VI in Port Renfrew BC

Dec. 14, 2014

Port Renfrew BC

Surfrider Foundation Vancouver Island chapter is helping to coordinate citizen science sampling in the South Island region and in particular Port Renfrew.  SurfRider_VI_logo

Lucas Harris is Vice Chair of the chapter and headed out to catch the surf yesterday.  Surfrider will begin coordinating with interested volunteers in Port Renfrew for the January 2015 sampling.  Thanks to Surfrider for all of the help in making the InFORM project a success thus far.  If you are interested in the health of our oceans and are interested in connecting with like minded people who also love to surf check out their organization.
