During the next few months, VIMS scientists will be providing an inside look into their experiences as they visit the waters around Antarctic on research expeditions. Mar Arroyo, a first-year VIMS graduate student affiliated with Dr. Elizabeth Shadwick’s laboratory, will take part in a cruise to East Antarctica from mid-December through January. Meanwhile, researchers led by Dr. Deborah Steinberg will be taking part in the Palmer Long-Term Ecological Research Program (PAL-LTER) at the U.S. Palmer Station on the Antarctic Peninsula from late December to mid-February.
Shadwick Lab Expedition
I’m a first-year graduate student in Dr. Elizabeth Shadwick’s lab at VIMS. I received my BSc in Marine and Atmospheric Science from the University of Miami in May 2016, with a focus in chemical oceanography. At UM, I spent more than 60 days at sea, participating on research cruises with NOAA and CLIVAR/GO-SHIP. I’m interested in inorganic carbon chemistry in the Southern Ocean and the impacts of the changing sea-ice environment on the carbon cycle. For the next six weeks, I will be on a voyage to the Southern Ocean and the Mertz and Totten Glaciers in East Antarctica on the RV Aurora Australis. The Totten Glacier has been recently named the fastest thinning glacier in East Antarctica. I’m excited to see the changes to the carbon system from years ago because of this glacier melt.
Growing up on the coast of Maine, the ocean has always been an important part of my life. Studying at Bowdoin College, I realized I was very interested in the interactions between the physics and biology of the ocean. Plankton are the ideal organisms for studying these interactions as passive drifters of the ocean. The Antarctic represents an environment still relatively understudied, particularly regarding plankton. My interest in climate change and plankton led me to pursue my Ph.D. in Dr. Steinberg’s zooplankton ecology lab. For my dissertation, I have the opportunity to conduct research on the Palmer Antarctica Long-Term Ecological Research cruise every January. Specifically, I am studying pteropods, open-ocean snails important in food-web and biogeochemical cycling, and how they may be affected by climate change in the region.
I am a first-year graduate student at the Virginia Institute of Marine Science working with Dr. Debbie Steinberg. Our research group is participating in the 25th annual Palmer Antarctica Long-Term Ecological Research (PAL LTER) cruise this January. I went on my first PAL LTER cruise two years ago as a William & Mary undergraduate and have since hung around the Steinberg lab with hopes of getting back to the ice. My broad scientific interest lies in how ecosystems respond to climate change. Rapid warming in the region we study—the Western Antarctic Peninsula—has lead to substantial ice loss in recent decades. I am excited to join researchers from around the world working to identify the implications of these changes.
ng my Honors thesis on acorn worm ecology and intertidal zonation. Dr. Steinberg offers a spot on the cruise to a William & Mary undergraduate each year, and this year I was lucky enough to get chosen! I look forward to expanding my research experience through this trip!
