New Paper: Depth drives the distribution of microbial ecological functions in the coastal western Antarctic Peninsula

Congrats to Avishek Dutta and the team for their recent paper in Frontiers in Microbiology. Here’s the abstract… The Antarctic marine environment is a dynamic ecosystem where microorganisms play an important role in key biogeochemical cycles. Despite the role that microbes play in this ecosystem, little is known about the genetic and metabolic diversity of […]

2023 PAL-LTER, SWARM, and Friends Workshop

Four years is a long time to wait, but last week, the waiting was over, as we held the first in-person PAL-LTER and Friends Science Workshop since 2019. On Tuesday, the PI team met to discuss the latest field season and to prepare for the challenges of next one. And then on Wednesday and Thursday, […]

An Adélie Penguin on the cover of Ecosphere

Kudos to PAL researcher Darren Roberts, whose photo of an Adélie Penguin was featured on the March 2023 issue of Ecosphere, the journal of the Ecological Society of America. The photo was chosen to feature a recent paper, Long-term patterns in ecosystem phenology near Palmer Station, Antarctica, from the perspective of the Adélie penguin, by […]

Record Low Antarctic Sea Ice Extent in 2023

Last month, the amount of sea ice around Antarctic broke a new record low, according to the National Snow & Ice Data Center. This year’s minimum extent is the lowest recorded since 1979, and it broke the previous record low set just last year. Following the low, and the peak of austral summer, the sea […]


2023 Palmer School Outreach Programs Underway

It’s hard to believe the 2023 PAL field season is halfway over, and the main research cruise is already back at port. But that doesn’t mean our outreach work is done. Far from it, we’re just getting started! The goal of the PAL outreach team is to bring Antarctic research to classrooms across the country, […]


2023 Virtual Classroom Programs

Educators: Sign-up now to join Polar Scientists on a research expedition to Antarctica We are currently recruiting 12-18 educators and their students (grades 5-9) to join the Palmer Station Long-term Ecological Research Program (PAL LTER) team on their 2023 field season in Antarctica. Students will learn about Antarctic food web ecology and how scientists are using […]
