Andreas received a Master degree in Biology from Stockholm University 2015. As a PhD student, in the lab of Dr. Rachel Foster at Stockholm University, his research is focused on microbial symbiotic relationships between Diatoms and nitrogen-fixing cyanobacteria. He is specially interested in how the coordination and communication within these associations depend on external environmental … Continued

Melody graduated as valedictorian of SciTech High School in Pennsylvania, class of 2013. She is currently pursuing a Bachelor of Science in Biology, with a concentration in Marine Biology, and a minor in chemistry from Millersville University. She has participated in undergraduate research involving marine primary productivity and organism distribution. She is looking forward to … Continued
Sarah Weber is a new PhD student in Biological Oceanography at the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) in Germany, where she is a part of Dr. Maren Voss’s working group. Sarah has a general interest in marine biogeochemistry, with a focus on nitrogen fixation (diazotrophy). For her thesis, Sarah will be exploring … Continued
Cruise Report: Ecosystem Dynamics of Hydrothermal Vent Communities
Long before heading out for a major multidisciplinary research cruise like this one, most ships’ captains, funding agencies, and participants expect to have a detailed Cruise Plan in their hands. I’ve been chief scientist on 38 research cruises over the years and now know these documents are actually Fantasy Plans. When you work in the deep … Continued
Maren Voss studied Biology and Biological Oceanography in Kiel, Germany, at the Institute of Marine Research (today called GEOMAR). Her PhD was on carbon and nitrogen stable isotope signatures in sedimenting particles and how the history and processes of the upper water column are reflected in these data. To learn the specific analytical method for … Continued
Joseph Montoya is a biological oceanographer with research interests at the interface of biology and geochemistry. His lab specializes in studies of the marine nitrogen cycle and the role of N2-fixation (diazotrophy) in structuring the flow of nitrogen and energy through planktonic ecosystems. Much of his lab’s work has focused on N cycle processes in … Continued
Annalisa Bracco is a professor in the School of Earth and Atmospheric Sciences at Georgia Tech. She is a physical oceanographer and her group’ research focuses on understanding the role of the ocean circulation in transporting and mixing physical and biogeochemical tracers at scales ranging from 100 m to ocean basins. She is particularly interested in linking physical processes to climate variability, biodiversity and … Continued
