On the I08S, we have Participants and Principal Investigators from 16 different institutions and 7 different countries. Here, who we are and what we are going to do during the I08S Cruise. The list is still incomplete!
Alison M Macdonald, Woods Hole Oceanographic Institution
I am chief scientist for the 2016 I08S cruise; a physical oceanographer with a great interest in the large-scale currents of the ocean and the characteristics of ocean properties. As we here on the surface are beginning to see changes in our environment that we attribute to the carbon dioxide and other greenhouse gasses that we have been putting into the atmosphere for the last 300 years, so too are we seeing changes in the ocean. I am particularly interested in how deep currents move water properties that are changing with time around the globe. As chief scientist my main task is to ensure that all groups involved in our expedition have ample opportunity to measure the broad variety of ocean properties they intend to investigate.
I am co-chief scientist for the 2016 I08S cruise. Currently, I am studying the circulation of the Red Sea, an extremely salty marginal sea in the North Indian Ocean. I did my BSc in Oceanography and a Master Degree in Remote Sensing both in Brazil. I have completed a PhD in Marine Sciences at University of Tasmania (Australia) in 2015. My PhD research was about the currents of the South Indian Ocean and the impacts of salinity on the circulation. During my PhD, I have participated in two cruises in the South Indian Ocean, mostly dedicated to measure the eastward South Indian Countercurrent and the Leeuwin Current System.
Heather Page, Scripps Institution of Oceanography
Being stung by a jellyfish as a young girl first sparked Heather Page's
interest in marine biology. She earned undergraduate degrees in Marine Biology and Environmental Sciences from University of North Carolina Wilmington. She is currently a PhD Candidate at the Scripps Institution of Oceanography where she studies ocean acidification on coral reefs. During the cruise, she'll be assisting with alkalinity measurements.
Having grown up surrounded by both the North and Baltic Sea in northern Germany, becoming an oceanographer has long been a dream of mine.
After an undergraduate degree in physical oceanography at the University of Kiel / GEOMAR in Germany, I focused on interdisciplinary ocean sciences during my master studies at the University of Bergen, Norway.
I am currently a PhD student at ETH Zürich. I use a biogeochemical model to assess controlling factors of phytoplankton biogeography in the Southern Ocean, with a particular focus on coccolithophores and diatoms. Furthermore, I am interested in the implications of changes in phytoplankton community structure on biogeochemical cycles. On this cruise, I'll be assisting with chlorophyll and CDOM measurements.
Earle Wilson, University of Washington
I am a fourth-year graduate student in the School of Oceanography at the University of Washington. At present, my main research interest is Southern Ocean dynamics. More specifically, I use model simulations and ocean observations to investigate the processes that control circulation and mixing in the Southern Ocean. I am also part of the Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) group. While on board the Revelle, I will assist with the collection of hydrographic data and deploy Argo floats for the SOCCOM project. This will be my first multi-week research cruise and my first time visiting the Southern Ocean!

Natalie Freeman, University of Colorado BoulderI grew up about 30 miles from Kansas City (go Royals! go Chiefs!) with a special love for school/learning, dancing, violin and musical theatre. Somewhere along the way I caught the 'bug' for all things climate. In 2012 I earned a BS in Mathematics (and a minor in Dance) from the University of Kansas. Currently, I'm a 4th year PhD student at the University of Colorado Boulder in the Department of Atmospheric and Oceanic Sciences and affiliated with the Institute of Arctic and Alpine Research (http://instaar.colorado.edu/people/natalie-freeman/). I'm fascinated by and passionate about the Southern Ocean because of its integral role in the climate system - my research thus far has focused on using a combination of hydrographic and satellite data to investigate changes in Southern Ocean biogeochemistry and frontal systems. On I08S, in addition to the duties as a CTD watch-stander, I look forward to working with the scientists and the other students and being exposed to and learning about the many facets of observational oceanography. Given my research interests, I'm particularly excited to actually help sample the Southern Ocean and cross the Antarctic Polar Front! I extend my utmost gratitude and thanks to the I08S team and the generous funding agencies for this unique learning opportunity and experience.
David Webb, University of New South Wales I completed my undergrad in physics and mathematics at the University of New South Wales (UNSW) and am presently a PhD canditate for Climate Science at the Climate Change Research Centre (CCRC) at UNSW. My current research is focused on wave dynamics in the Southern Ocean. In particular, I am using idealised model simulations to investigate how coastal structures and topography can influence the temperature and density structure of Antarctic coastal waters, and the impact this has on global climate. During my time on the I08S cruise I will be participating as a CTD watch-stander. This will be my first encounter with observational oceanography and I'm very excited to be working and learning with a new group of students and researchers whilst in the Southern Ocean.
Sarah Bercovici, RSMAS University of MiamiI’m a fourth year graduate student in the Ocean Sciences department at the Rosenstiel School of Marine and Atmospheric Science (RSMAS) at the University of Miami. My focus is marine chemistry, and I’m interested in biogeochemical cycling on Antarctic Shelves and in the deep Southern Ocean. In particular, I would like to understand how local biogeochemical processes at these high southern latitudes influence the deep ocean on a global scale. On this I08S cruise, I’ll be the student assistant for the CFC (Chlorofluorocarbon) group and I will be collecting radiocarbon samples for dissolved organic carbon.
Jim Happell, RSMAS University of Miami
I am an Associate Research Professor in the Department of Ocean Sciences at the University of Miami. I also direct the Tritium Laboratory at the Rosenstiel School of Marine and Atmospheric Science (RSMAS). I specialize in providing high quality measurements of anthropogenic tracers such as Tritium, Sulfur hexafluoride (SF6) and Chlorofluorocarbons (CFCs) that can be used to provide time information on deep ocean circulation patterns. On the I08S expedition, I will serve as the lead SF6/CFC technician.

Norm Nelson, Earth Research Institute, University of California, Santa Barbara (UCSB)
Maverick Carey, University of California, Santa BarbaraI grew up in Honolulu, Hawaii and have loved surfing, fishing, and the ocean in general my whole life. I got my undergraduate degree in Marine Science, with an earth systems emphasis, from the University of San Diego. There I worked as part of a research team that compared sedimentation between developed and undeveloped watersheds on St. John, USVI. I now live in Santa Barbara, and work as a lab technician in the Carlson Lab at UCSB (University of California, Santa Barbara). I run Dissolved Organic Carbon analysis on seawater samples, with the goal of understanding the interaction between microbial communities and organic matter in the ocean. On the I08S cruise I will be collecting seawater samples for Dissolved Organic Carbon analysis, as well as assisting in collection of radiocarbon samples.
I am the manager and supervisor for the Oceanographic Data Facility (ODF) within Shipboard Technical Support (STS) at Scripps Institution of Oceanography. STS/ODF provides the hydrographic data from CTD casts and discreet analysis of salinity, nutrients and dissolved oxygen for global repeat hydrography programs. I will be doing the onboard analysis of nutrients (nitrate, phosphate, silicate, nitrite, and ammonia). I will also oversee the analytical analysis and data quality of dissolved oxygen and salinity.
I am from the University of Miami onboard the Revelle to measure CFCs and SF6 along with Jim Happell. I am Lab Supervisor of Daily Operations at the Tritium Lanoratory, and usually measure tritium in my regular work, but am hiring on to measure the CFCs on this mission. This is my 4th trip to the Southern Ocean.
Michael Fong, Scripps Institution of Oceanography
I am a third year graduate student at the Scripps Institution of Oceanography. My interests are in the chemistry of CO2 in seawater and the changes in ocean chemistry that result from increasing oceanic uptake of atmospheric CO2. In the Andrew Dickson lab at SIO, my work has been focused on validating and refining spectrophotometric pH measurements. On the cruise, I will be making pH measurements.Michael Fong, Scripps Institution of OceanographyLand-Based:
Although I earned my degree as a Physical Chemist from the University of Miami, I got very interested in Oceanography while doing my thesis under Frank J. Millero at the Rosenstiel School of Marine and Atmospheric Science (RSMAS). I now lead the “Autonomous pCO2 on ships” program at NOAA/AOML in Miami, FL. Our purpose is to outfit ships of opportunity (SOOP) with our “State of the Art” autonomous underway surface pCO2 system and collect data in a continuous mode over the recurring track of commercial and research vessel in order to monitor the spatial and temporal variations of the CO2 system over the oceans. For this cruise, I will install one of our instrument onboard the Roger Revelle to collect high quality surface pCO2 data.
Andy Pickering, Oregon State University College of Earth, Ocean, and Atmospheric Sciences
I'm a postdoctoral research associate at Oregon State University, working with Jonathan Nash. My research looks at internal waves and mixing, and how those affect larger scale ocean circulations. I won't be sailing on the I08S cruise, but am traveling to Perth beforehand to help install 'chi-pod' instruments on the CTD frame. These are sensors developed by the Ocean Mixing Group at Oregon State University that measure small temperature fluctuations caused by turbulence, from which we infer rates of turbulent mixing and diffusivity. I'll be training and working with Hannah Dawson, who will watch over the instruments during the cruise and hopefully troubleshoot any problems that arise.
Anill Rick Rupan, University of Washington
I am a research engineer at the University of Washington (UW) School of Oceanography where I manage the day to day operations of the Argo (http://www.argo.net/) and SOCCOM (http://soccom.princeton.edu) float programs. I will be preparing 11 SOCCOM floats to be deployed in the southern ocean off of the R/V Revelle. The floats will take temperature, salinity, pressure, pH, nitrate, fluorecence, and optical backscatter readings of the 2000m of the souther ocean every 10 days for the next 5 - 7 years. This data will help scientists accross to world learn more about the how the southern ocean effects the worlds climate.
François Fripiat, Vrije Universiteit Brussel (Belgium)
I'm currently a postdoc in the Analytical, Environmental, and Geo-chemistry department at the Vrije Universiteit Brussel (Belgium). My research interest is on the application of stable isotopes (N, Si, O) to unravel biogeochemical cycles both in the modern and past oceans. During the IO8S cruise, I won’t be onboard but nitrate δ15N and δ18O will be sampled for us. Our main interest will be in the calibration of this proxy for paleoceanography purposes and to better understand what processes control the partitioning of nitrogen along with the meridional overturning circulation. The δ15N of particulate matter in sediments provide a view of nutrient consumption:supply ratio in past oceans and are used to formulate and test hypotheses on ocean productivity and fluctuations in atmospheric pCO2 over glacial cycles.
