Sea Ice, Ice Cores, & Brine Life
The ocean is going through drastic ecological changes that are most visible in polar regions. Scientists primarily study the impacts of climate change on ice sheets, sea ice, marine ecosystems and atmospheric conditions to understand the dynamics undergoing such systems.
The diversity, adaptations, and ecological roles of microbes from limited nutrients, high and low light concentrations, and changing ice have long lasting effects on the larger ecosystems.
Ongoing research by oceanographer, microbial ecologist and National Geographic Explorer Alli Fong and the Perpetual Planet team aims to deepen our understanding of polar microbes and their vital ecological roles, helping us better grasp the impacts of climate change on these fragile systems. By studying sea ice cores—long cylinders of ice drilled from sea ice and glaciers—they can learn about historical climate conditions and the ecosystems trapped within. These cores contain air bubbles, temperature data, and microbial life that offer insight into both past environmental conditions and current biological processes.
