A Diamond Jubilee for Line P

“In a time when you can work on Line P data without actually being to sea, who here has been to Station Papa?” About 2/3 of the hands in ~100 person room go up. “Who’s been since 2000?” 40 hands. “Who went in the 90’s?” 20 hands. “In the 80’s?” 10 hands. ” In the 70’s?” 5 hands. “In the 60’s?” Still, 2 hands go up. “Who’s been in winter?” 15 hands up, a hearty “Thank You!” and a round of applause from the room.

This was the amazing group that I was surrounded by at the two day meeting celebrating 60 years of science on Line P at the Institute of Ocean Sciences in Sidney, BC the last grey days of November, 2016. In this room sat some of the great forethinking oceanographers of a generation that have tirelessly pushed for continued funding, and collected samples, at what is now the longest continuously monitored station in the entire global ocean.

Update on Offshore Seawater Monitoring: Interview with CFAX 1070 AM

Interview with Ian Jessop on CFAX 1070 AM Radio in Victoria about newly published offshore monitoring data from InFORM and our partner project Our Radioactive Ocean.  Interview begins at the 33:50 mark of the Soundcloud file below.

 

Summer 2014 Offshore Monitoring for Fukushima Contamination

By Jonathan Kellogg and Jay T. Cullen

Results from surface water samples collected in August 2014 during three oceanic research cruises are now available. These seawater samples were analyzed to characterize the distribution of Fukushima derived radionuclides 137-Cesium (137Cs half life ~30 years), and 134-Cesium (134Cs half life ~2 years). Based on the distribution of 134Cs, the Fukushima plume was not consistently present yet on the BC coast. It is likely that peak concentrations of radiocesium will be present offshore in the next year.

Update: Sampling for Fukushima Derived Radionuclides in the Northeast Pacific and Arctic 2015

By Jay T. Cullen

Locations where surface seawater samples were collected for the InFORM project in July 2015. Surface seawater temperatures at the time of collection are shown with values greater than 16C in the anomalous region referred to colloquially as “the blob”.


The purpose of this short post is to update readers on the activities of the Integrated Fukushima Ocean Radionuclide Monitoring (InFORM) project. This post is the most recent in a series documenting scientific research into the impact of the Fukushima Dai-ichi disaster on environmental and public health. Surface seawater samples were collected from the icebreaker CCGS Sir Wilfrid Laurier as it traveled between Victoria BC to Dutch Harbor Alaska during July 2015. These seawater samples will be analyzed to characterize the distribution of Fukushima derived radionuclides 137-Cesium (137Cs half life ~30 years), and 134-Cesium (134Cs half life ~2 years). As in previous years this information will help to determine how well model predictions of the activities and progression of ocean borne contamination across the Pacific Ocean match with observations. Understanding the spread of this contamination provides important information on the impact of the Fukushima Dai-ichi disaster on the health of the Pacific ecosystem and the North American public. The evolution of the contaminant plume in time and space also helps the scientific community to better understand ocean mixing which is a key parameter toward understanding the oceans role in mitigating atmospheric greenhouse gas increases and climate change.

Sampling for Fukushima Derived Radionuclides in the Northeast Pacific and Arctic 2015

By Jay T. Cullen

Bow of the CCGS Laurier. Great ship and crew for science operations in the Arctic.
The purpose of this short post is to update readers on the activities of the Integrated Fukushima Ocean Radionuclide Monitoring (InFORM) project. This post is the most recent in a series documenting scientific research into the impact of the Fukushima Dai-ichi disaster on environmental and public health. Today the icebreaker CCGS Sir Wilfrid Laurier will leave Victoria BC bound for Dutch Harbor Alaska and then up through Bering Sea and Strait to the Arctic Ocean. On the way the InFORM project will collect surface seawater to characterize the distribution of Fukushima derived radionuclides 137-Cesium (137Cs half life ~30 years), and 134-Cesium (134Cs half life ~2 years). As in previous years this information will help to determine how well model predictions of the activities and progression of ocean borne contamination across the Pacific Ocean match with observations. This provides important information on the impact of this contamination on the health of the Pacific ecosystem and the North American public that rely on the ocean for their food, livelihood and recreation. The evolution of the contaminant plume in time and space also helps the scientific community to better understand ocean mixing which is a key parameter toward understanding the oceans role in mitigating atmospheric greenhouse gas increases and climate change.
