Hannah and Susan are off to Antarctica!!!!
October 19, 2018
Hannah Dawson and Susan Rundell are about to set sail across Drake Passage to Palmer Station on the Western Antarctic Peninsula. Once there, they’ll spend 2 months studying sea-ice algae and phytoplankton to understand their importance for Antarctic coastal ecosystems. Good luck!
You can follow their adventures on Susan’s blog (http://antarcticalgae.home.blog), on twitter (@uw_young) and instagram (youngalgae)
Susan Rundell has started her dual PhD in Oceanography and Astrobiology at UW. She’ll be studying marine Rubiscos and is off to Antarctica with Hannah Dawson for some exciting fieldwork. Congratulations Susan on being awarded a very prestigious NSF Graduate Research Fellowship!
We’re off to study sea ice algae in Antarctica!
We have been funded through the National Science Foundation Office of Polar Programs to study how sea ice algae deal with large changes in salinity and temperature during the spring melt. This research will help us understand the underlying mechanisms that control biological productivity in the Western Antarctica Peninsula and how it may change in the future.
Simons Foundation Early Career Award in Marine Microbes
Jodi Young has received an Early Career Award from the Simons Foundation to study how marine Rubiscos play a key role in global carbon fixation and how this role may influence CO2 fixation rates by phytoplankton in the future.
UW Innovation Award!
We are the recipients of a 2018 UW Innovation Award to build a laboratory scale system to grow sea ice and study the microbes that live within it!

Polar Science Weekend at the Pacific Science Center
March 2-4, 2018
Hannah Dawson was part of the "Polar Science Weekend 2018” at the Pacific Science Center in Seattle. Together with Zac Cooper of the Deming Lab Group (UW), we demonstrated how life can evolve in extremely cold environments, such as sea-ice brines.
Welcome our newest member!
Big welcome to Connor Williams, born Feb 23rd. Future Oceanographer! (notice he’s already sporting an awesome Palmer Station, Antarctica onesie)

Congratulations Viviana for a fantastic senior project in our lab, investigating "Productivity of Antarctic Diatom Nitzschia lecointei with the addition of Glycine betaine under different salinity concentrations". Great presentation and report. Well done and Good Luck in your future endeavors!!!
Fieldwork in Barrow, Alaska: Studying sea-ice algae
May 4th - 11th, 2017
The Young Lab group joined with the Deming Lab group (UW) to collect biological samples from sea ice near Barrow, Alaska as part of the Gordon and Betty Moore Foundation funded project "Understanding infection dynamics among marine viruses and microbial hosts in extreme polar environments". We had a great time riding snow mobiles, coring ice and learning about the local Barrow community. For more details on the work we were doing, check out our research page. We can't wait to go back!
Protocols paper out! Measuring Rubisco kinetics in diatoms

New paper out – Rubisco kinetics in diatoms
May 23rd, 2016
Diatoms are important primary producers in the ocean. This recent study published in the Journal of Experimental Botany shows that the enzyme used to fix CO2 during photosynthesis, Rubisco, has a much wider kinetic variation in diatoms than previously thought, which influences the requirement for carbon concentrating mechanisms. The lack of a relationship between Rubisco catalytic speed and CO2 affinity in diatoms contradicts our current understanding of Rubisco catalysis and highlights the need to study a wider range of photosynthetic organisms. Check it out here!
