Image Of the Day repeat Caption:
Kristen Hunter-Cevera cultured different types of colorful phytoplankton called Synechococcus, found in seawater samples from WHOIs Martha's Vineyard Coastal Observatory (MVCO). Hunter-Cevera, who recently earned her Ph.D. in the MIT-WHOI Joint Program, also used data from the FlowCytobot, an automated underwater microscope developed by WHOI scientists Heidi Sosik and Rob Olson, that tracked phytoplankton levels at MVCO for the past 13 years. Hunter-Cevera was lead author of a recent study that showed that as ocean temperatures rose over that time, annual blooms of Synechococcus occurred up to four weeks earlier than usual. Shifts like these could have major impacts on marine ecosystems.

Kristen Hunter-Cevera's Ph.D. thesis focused on exploring and understanding the population dynamics and diversity of photsynthetic bacteria called Synechococcus observed at the Martha's Vineyard Coastal Observatory (top). But getting them to grow in the lab, so she could study them in detail, proved challenging.
Image Of the Day caption:
Kristen Hunter-Cevera investigates abundant organisms in the ocean, a photosynthetic bacteria called Synechococcus, that are also an important food source in the marine food chain and produce a significant portion of Earth's oxygen. Despite their importance, they are hard to observe in open ocean, and some are hard to grow in the lab. Two WHOI scientists who discovered Synechococcus in the 1970s, John Waterbury and Freddy Valois, helped the MIT-WHOI Joint Program graduate student grow different types of Synechococcus cultures, distinguished here by different colors. so she can study the physiological and ecologial differences governing where and when they grow.
