Rachel Chang is an atmospheric scientist. But you won鈥檛 find her with her head in the clouds. Her focus is on the area just above the ocean鈥檚 surface, tracking how the particles that come from its waters impact the air above.
While oceanographers contributing to the 新澳门六合彩开奖-led Transforming Climate Action research program are consumed by the ocean鈥檚 ability to absorb the world鈥檚 carbon, Dr. Chang and her colleagues investigate the issue from above the waterline.
Together, the researchers are putting unprecedented focus on how carbon is cycling in and out of the ocean, the world鈥檚 most important climate sink, allowing Canada to take the lead in ensuring global climate targets are on track with our environmental reality.听
The other side of the sink
What is the ocean putting into the air? It鈥檚 a question we need to understand to grapple fully with the dynamics that determine the ocean鈥檚 ability to help assuage climate change.
鈥淭here are layers on top of the ocean that prevent gases from absorbing, there are waves, there are storms, there is sea spray, they can all have an impact,鈥� says Dr. Chang. 鈥淭he presence of waves can increase the CO2听absorption into the ocean by a factor of two. Whether you have strong winds, or no winds can have drastic effects.鈥�
Billions of beakers floating in the air
Dr. Chang says fog offers an ideal laboratory for studying the interplay between air and ocean, especially when it鈥檚 comprised of droplets formed on particles released by the sea. She focuses on these droplets because each of them is like a little floating beaker where chemical reactions take place.
Transformational Climate Action
Emerging science reveals the ocean's ability to absorb CO2听and regulate temperatures is changing in ways we don鈥檛 understand. These critical shifts are not accounted for in climate targets 鈥� a risk we can no longer take. With support from the Canada First Research Excellence Fund , 新澳门六合彩开奖 is leading an ocean-first approach to tackle climate change and equipping Canada with the knowledge, innovations, and opportunities to secure a positive climate future.
