From space to the deep sea
Phytoplankton ecology, ocean color remote sensing, deep sea carbon export, and more

Welcome!
Hi, I’m Dr. Sasha J. Kramer (she/her)! In July 2025, I started my lab as an Assistant Professor at Boston University in the Department of Earth & Environment.
Research in my lab focuses on characterizing surface ocean phytoplankton communities using a combination of in-water data and remote sensing. From these surface ocean measurements, we can consider the implications of changing phytoplankton community composition for biogeochemical cycles (e.g., carbon export) and in response to extreme events like coastal wildfires. My work combines oceanographic fieldwork, remote sensing data, and lab work using optical and molecular tools. I enjoy incorporating new approaches and methods to observe phytoplankton across scales. Please feel free to contact me if you have questions, are looking for code or data that is not here or on PANGAEA, SeaBASS, or GitHub, or need a copy of a paper that you can’t find online.
