The ocean’s contribution to climate change may not be as visible as that of the atmosphere, but in lock-step with the atmosphere, the ocean is changing. The physical dynamics of its currents and temperature are changing, as well as its chemical and biological aspects; its biogeochemistry. Knowing the ocean’s biogeochemistry, including ecosystem health and the ocean’s ability to absorb carbon, … Read More about Observing ocean health: RBR, Dalhousie and DFO collaborate to develop new biogeochemical sensors
It Walks the Line: a Wirewalker™ record deployment
In September of 2016, a surface wave-powered Wirewalker™ descended to the bottom of its 100-m wire, reversed direction, and smoothly ascended to the surface. Onboard, a payload of instruments took detailed measurements of physical and biological properties in Southern California’s La Jolla submarine canyon. It was the first cycle the Wirewalker would complete at the La Jolla canyon mooring – … Read More about It Walks the Line: a Wirewalker™ record deployment
Lake Tahoe’s Nearshore Network and Protecting Water Clarity
Renowned for its cobalt blue colour and clarity, at 1,900 m elevation, Lake Tahoe is North America’s largest alpine lake. It straddles the California-Nevada border and on all sides rise the peaked Sierra Nevada mountains. Over two million people visit the Tahoe region annually; Frank Sinatra once owned a casino on Lake Tahoe’s shore. It’s little surprise then, that when … Read More about Lake Tahoe’s Nearshore Network and Protecting Water Clarity
Fin-ished? Citizen scientists cast CTDs as part of an investigation of salmon mortality in British Columbia’s Salish Sea
In 2014, the Salish Sea Marine Survival Project (SSMSP) began, launching over thirty scientific studies into the lifecycle of Coho and Chinook Salmon of the Salish Sea. These West Coast fisheries collapsed over twenty years ago, and have not since recovered. At the close of this five-year program, researchers hope to understand why salmon mortality is so high. Their aim … Read More about Fin-ished? Citizen scientists cast CTDs as part of an investigation of salmon mortality in British Columbia’s Salish Sea
