The significance of PACE and its study of phytoplankton populations lies in its potential to enhance our understanding of ocean health and address challenges related to harmful algal blooms (HABs). The article states that "Understanding phytoplankton health can help predict harmful algal blooms," indicating that improved knowledge of these organisms is crucial for anticipating and mitigating the impacts of HABs, which can harm marine life and human health. Furthermore, the text highlights that "HABs can generate harmful toxins that sicken marine wildlife and humans," demonstrating the urgency of monitoring phytoplankton, since they are integral to both ecosystem health and public safety. Therefore, PACE's advanced measurements of the ocean's surface will provide vital information for managing and protecting marine environments from the detrimental effects of HABs, making its mission highly relevant.
"A Walk Through the Rainbow with PACE"
by Jessica Merzdorf
Why are there so many songs about rainbows? For NASA’s upcoming Plankton, Aerosol, Cloud, ocean Ecosystem mission, or PACE, the colors of the rainbow — or, if you prefer, the visible wavelengths of the electromagnetic spectrum — are the key to unlocking a wealth of new data on skies and seas around the world.
PACE’s high-resolution instruments will see ocean and atmosphere features in unparalleled detail when the mission launches in 2023. By measuring the intensity of the color that exits Earth’s ocean surface, PACE will capture fine details about phytoplankton — tiny plantlike organisms and algae that live in the ocean — that are the basis of the marine food web and generate half of Earth’s oxygen. Beneficial phytoplankton communities fuel fisheries, but harmful algal blooms (HABs) can poison animals and humans and disrupt tourism and fishing industries. . .
Understanding phytoplankton health can help predict harmful algal blooms, or HABs. When substances from land wash into the ocean, they sometimes become a feast for algae, allowing them to eat, grow and multiply rapidly. HABs can generate harmful toxins that sicken marine wildlife and humans and deplete oxygen in the water as bacteria feed on numerous dead algae.
“Harmful algal blooms are not recent. We have writings from indigenous tribes in the Pacific Northwest that talk about things happening on the beach,” said Cetinić. “It’s just that today we’re looking for it more, and also anthropogenic influences are making blooms more prevalent.”
