Our polar oceans and diatoms, a kind of microalgae, in particular play a major role in regulating atmospheric carbon dioxide. Led by oceanographers Dr. Rebecca Robinson and Dr. Mark Brzezinski, our SNOWBIRDS Transect team has been studying how the influence of nitrogen and silicon on the productivity of diatoms is recorded in sediments.

Cleaning up a sea of data

October 5, 2017 Gabi Serrato Marks 0 Comments data, database, deep-sea, Ocean, oceanography

Oceanographers have been drilling sediment cores from the ocean for decades to understand past ocean conditions, but they have inconsistent archiving techniques. In other words, the data was a mess. A new database brings together more than 2,000 sediment cores from the North Pacific, which will help us better understand the ocean and climate over time.
