 ### Ian Carroll
 
-Dr. Ian Carroll is a data scientist in the Ocean Ecology Lab (OEL) at NASA Goddard Space Flight Center and associate research faculty at the University of Maryland Baltimore County, with a background in mathematical ecology and cyberinfrastructure education. Project scientists in the OEL work closely with the Ocean Biology Distributed Active Archive Center (OB.DAAC) to improve satellite data products for ocean biogeochemistry and atmospheric science. As a NASA Openscapes mentor, Ian will help the ocean color research community navigate the OB.DAAC's transition to Earthdata Cloud, which commences with the [PACE Mission's](https://pace.oceansciences.org/) first light in early 2024.

+Dr. Carroll is an Associate Research Scientist at the University of Maryland Baltimore County working at NASA Goddard Space Flight Center on phytoplankton community ecology and data science. Phytoplankton are a diverse collection of photosynthetic organisms, found in all water bodies, that range in size from less-than a micron to millimeters in length. Despite their small size, their presence in the photic zone can be detected from space due to their light-absorbing pigments. Dr. Carroll investigates machine learning approaches to predicting the community composition (abundances of each type) of phytoplankton using data from ocean color instruments. He also supports science data production for NASA's PACE mission.
