Students and faculty at Yellowstone National Park on the Fall 2015 UWAB workshop.
Graduate student Elena Amador at the NASA Nordic Astrobiology Summer School in Iceland
Graduate Student Giada Arney at Shark Bay in Western Australia. Shark Bay is home to living stromatolites, photosynthetic microbial mats that exist in the fossil record as early as 3.5 billion years ago.
Graduate student Brett Morris at Yellowstone National Park's Grand Prismatic Spring, studying the microbes that lend the spring its bright colors.

Early earth's air pressure was less than half of today's

A new study led by UWAB alum Sanjoy Som together with UWAB professors Roger Buick and David Catling and others implies that early Earth's atmospheric pressure 2.7 billion years ago was less than half of modern day. The researchers used gas bubbles trapped in ancient sea-level lava flows as a "paleobarometer". The sizes of the bubbles record the pressure of the atmosphere bearing down on the cooling lava billions of years ago. This low atmospheric pressure suggests that early microbes may have been consuming atmospheric nitrogen, but there was not an efficient process to release that consumed nitrogen back to the atmosphere like there is today.
