Rin Moriyasu

Rin received his BA in chemistry from Whitman College in Walla Walla, WA. There, he studied the inclusion of water in biogenic aragonite of Scleractinian corals. He is currently a second year graduate student, in the Marine and Environmental Biology department at University of Southern California, working for Dr. James Moffett. Recently, Rin did fieldwork … Continued

Martin Wolf

Martin Wolf is an atmospheric chemist who studies the effects of aerosols on climate. His current research focuses on the role of particle chemistry in cloud nucleation, the radiative budget, and precipitation. He is also studying the effects of energy policy on anthropogenic particulate emissions. Martin’s goal for this cruise is to examine how sea … Continued

Nicole M. Travis

Nicole is a PhD candidate at Stanford University, studying oceanography under the guidance of Dr. Karen Casciotti. She is interested in marine nitrogen cycling, stemming from previous work in algal biofuel production and from studying ecological impacts of wastewater treatment plants. Her current projects investigate how algae and nitrifying microbes in the upper ocean leave … Continued

Justine Albers

Justine Albers joined Dr. Alyson Santoro’s research group at UC Santa Barbara as a technician after receiving her B.A. in Biology from Swarthmore College in 2017. In the Santoro lab, she studies the genetic diversity of nitrogen-cycling microbes in the ocean. She also works as a research technician in Dr. Lizzy Wilbanks’s lab at UCSB, … Continued

Dalton Hardisty

Dr. Dalton Hardisty is a paleoceanographer whose research focuses on reconstructing the distribution of redox-sensitive elements, mostly prominently iodine, in ancient seawater and links to oxygen availability in the geological past. This work includes placing both proxy constraints on ancient marine elemental cycles through measurements in sedimentary archives as well as experimental controls on processes … Continued

Jarek Kwiecinski

Jarek Kwiecinski is an undergraduate student studying environmental engineering at the Massachusetts Institute of Technology (MIT). Before coming to MIT, he worked with researchers at the University of New Mexico to study microbial growth efficiencies and nutrient cycling in desert soils. He now works as an undergraduate researcher in MIT’s Earth, Atmospheric, and Planetary Sciences … Continued

Diana Dumit

Diana graduated from Barry University in December of last year with a bachelor’s degree in Marine Biology and Chemistry, specializing in Biochemistry. She will be joining Dr. Andrew Babbin’s lab at MIT this fall as a graduate student studying the biogeochemistry of nitrogen. Her interests in biogeochemistry stems from past research on the cycling of … Continued

Karen Casciotti

Dr. Karen Casciotti is marine chemist who specializes in tracing the marine nitrogen cycle using stable isotopic measurements. Her current research focuses on understanding how nitrogen is cycled in oceanic suboxic zones. Of particular interest is how microbial processes control the inventory of bioavailable nitrogen in the ocean and the production of nitrous oxide, a … Continued

Colette Kelly

Colette Kelly is a graduate student in the Casciotti lab at Stanford University. Her area of focus is the cycling of nitrous oxide, a potent greenhouse gas, in oxygen minimum zones such as the eastern tropical North Pacific Ocean. Through field work, experiments, lab analyses, and modeling, she seeks to understand how climate-related changes to … Continued

Andrew Babbin

Dr. Andrew Babbin is a nitrogen biogeochemist, chemical oceanographer, or microbial ecologist, depending on whom you ask. He and his group study how microorganisms reshape their local environment, whether a coral reef, a hydrothermal vent, or in the case of this cruise, an oxygen minimum zone. The bablab, as they are known around MIT, try … Continued
