The Neuer Lab in ASU news!

The Neuer group’s latest achievement has been featured in a Biodesign Institute news story and on ASU Now, as the first laboratory group to receive a research grant in the new Center for Fundamental and Applied Microbiomics. This center’s mission involves the study of the structure and function of complex microbial systems, with the Neuer Lab’s focus being on the oceanic microbiome. The $687,521 National Science Foundation’s Biological Oceanography grant will allow the Neuer group, in collaboration with Associate Professor Dr. Hinsby Cadillo-Quiroz, to expand upon their research on the aggregation of pico-phytoplankton by incorporating both laboratory and field investigations – which will help shed light to the potential contribution that the eukaryotic fraction of pico-phytoplankton may have on the oceanic biological carbon pump in oligotrophic ocean regions.

Neuer, Susanne, Morten Iversen, and Gerhard Fischer. 2014. The Ocean’s Biological Carbon Pump as Part of the Global Carbon Cycle . Limnol. Oceanogr. e-Lectures, doi:10.4319/lol.2014.sneuer.miversen.gfischer. Abstract The Biological Carbon Pump includes all those processes in the ocean that cause organic carbon formed photosynthetically by phytoplankton (primary production) in the sunlit surface layer (the euphotic zone) to be removed from contact with the atmosphere. It is a mechanism that sequesters carbon dioxide (CO2) for weeks to hundreds or even millions of years (geological time-scales). Together with the physical carbon pump, the biological carbon pump constitutes the ocean’s CO2 sink, and these two major processes in the global carbon cycle have removed about 2- 2.5 Pg Carbon per year (last decade average)(I Pg=1015g). Today, about half of the CO2 emitted from fossil fuel burning and land use changes remains in the atmosphere, and the other half is captured by land sinks and the ocean. The modern carbon cycle is often completely separated from the short- and long-term carbon cycles of the geological past, and students from biology or biogeochemistry rarely learn about these processes and the respective timescales in a joint lecture. The purpose of this interdisciplinary lecture thus is to cover processes related to the biological carbon pump and how it functions, while paying close attention to the relevant timescales in the global carbon cycle. Note that we focus mainly on the production and sinking of particulates, we do not delve into detailed mechanisms of carbon sequestration due to the removal of dissolved organic matter. Topics will include an introduction to the different carbon pumps (biological, carbonate and physical), followed...
