Tell us a little bit about yourself. I am from the Northwest of the UK so was incredibly fortunate to grow up surrounded by national parks such as Eryri National Park (Snowdonia) and the UK coast. Thanks to this upbringing I am passionate about the outdoors and enjoy walking, cycling, bird watching and paddleboarding. I also enjoy travelling and have been lucky enough to visit some amazing places through my research. When I am at home, I enjoy cooking and exploring new cuisines.

What kind of scientist are you and what do you do? I find it quite hard to define what I do but broadly I am a palaeoecologist. My research focuses on understanding ecosystem responses and recovery from environmental stress using single celled marine organisms called foraminifera. Using a combination of techniques including geochemistry, statistical analyses and more recently micro-CT scanning I can understand how these marine organisms were growing, living, and evolving over millions of years and how that relates to the climate through geological time. I love learning new techniques and combining them with traditional methods to view ecosystems from a new perspective. One of the great things about my research is I get to wander through geological time and investigate interesting periods for example my current research focuses on ocean recovery following the end-Cretaceous mass extinction event (the one that killed the dinosaurs) but I am now also working on projects related to the Messinian Salinity Crisis when the Mediterranean Sea dried up.

What is your favorite part about being a scientist, and how did you get interested in science? I have always been interested in science, even as a small child I loved reading books about volcanoes and marine life. I really enjoyed science in school but really struggled with the pure science aspects, especially anything involving math, which I always felt would hold me back from being a scientist. Luckily, I had a great support network, and I was able to overcome a lot of these struggles and gain a place at the University of Leeds to study geology, a subject I was always curious about but never saw myself doing as a career. 14 years later and I’m still studying geology, so it was definitely a good choice! Geology turned out to be the ideal subject as it combine all the sciences to understand the world we live in. I am still intimidated by maths but try to push through that so much so that most of my research involves statistics and coding something I would never have though possible even five years ago. One of my favorite things about being a scientist, and a geologist, is the opportunity to travel. I have been able to visit at least six different countries including Chile and New Zealand and have participated in research expeditions to the South Atlantic and currently the Tyrrhenian Sea.

This is me on-board RRS Discovery in the South Atlantic standing next to the sediment cores we had just collected from the Falkland Plateau.

How does your work contribute to the betterment of society in general? A lot of my research focuses on understanding how ecosystems respond to climatic events which is really important and fundamental to understanding how ecosystems will respond to current and future human induced warming events. There is a lot of focus on ecosystem restoration in current scientific policy, particularly in the marine environment, yet there are still a lot of gaps in our understanding of recovery processes. My research works to address these gaps by using various events in geological time and uncovering the patterns and processes of ecosystem recovery. By filling in these gaps policy makers can make more informed decisions about marine restoration projects and marine monitoring.

What advice do you have for prospective scientists? I have been extremely fortunate to have had amazing mentors in my career and have therefore been given a lot of useful advice. The best piece of advice I’ve been given was to be patient. There is a pressure to continuously get results and keep moving on to bigger and better things and it’s very easy to get caught up in that mentality. But science takes time and sometimes in your career it can be much more beneficial to maybe take a sidestep and learn something new rather than pushing forward all the time. I still struggle with this advice but now try and take a step back before making big decisions. Another great piece of advice that is applicable for everyone is to write everything down. You might think you will remember, but you won’t! Even now I refer to notebooks from 8-10 years ago to get information or to go back to ideas I had but never had time to explore.

Victoria’s shipboard role is being a paleomagnetist.

Field work summer of ’22, Central Mongolia. The research team discusses structural geology problems. Victoria joined as a member of the Utah Paleomagnetic Center at the University of Utah.

Tell us a little bit about yourself. Describe your hobbies and interests outside of science. I spend a lot of time outdoors; skiing, hiking, rollerblading or skateboarding. I also read lots of fantasy books and enjoy listening to live music. I try to travel as often as I can and immerse myself in different cultures.

What kind of scientist are you and what do you do? I am a graduate student and I identify as a Rock Magnetist. I analyze the magnetic properties of rocks and minerals to learn more about geological processes, environmental conditions, and the history of Earth’s magnetic field. I am passionate about early geoscience education. I spent a year working with a local middle school, bringing hands-on experiments and facilitating field trips revolving around earth science and geology. I volunteer at outreach events as often as I can.

What is your favorite part about being a scientist, and how did you get interested in science? I have a very non-linear path. I took a few years off between high school and college, working at a local bar with no thought about higher education. I decided to go back to school and entered college as an anthropology major, took one geology course and fell in love. Our Geoclub held field trips every long weekend, where I was able to spend time camping outside with friends and learning about rocks. It is those moments that made me want to become a geologist. I also have an undergraduate degree in anthropology. I try to use it as often as possible, with my senior thesis being an archeo-magnetic study on Floridan potsherds. I am also currently involved in geoarchaeology research on roman concrete. I am president of Energy Club (an adaption of AAPG) at the University of Utah. With this club, I coordinate monthly seminars with industry professionals with the aim of teaching undergraduate student’s transferable skills (importance of machine learning in geoscience, adobe Illustrator for figure making, etc) and sharing career trajectories (hosting career panels filled with government, industry, and academics). We also hold a yearly department poster session with monetary awards for both graduate and undergraduate students. This coming year, we hope to hold an “earth science art exhibit” where students and professors can show off their artistic side with paintings of field sites, ‘beautiful’ data sets, and even a ‘bake your thesis’ category. 

Field work in the Tetons in Wyoming, we had to get helicoptered in and we camped on the ice!

How did you learn about scientific ocean drilling? I told my advisor I would love to be on a research vessel and he shared with me the call for a paleomagnetist for this expedition.

How does your work contribute to the betterment of society in general? Magneto stratigraphy helps us date sediments. Rock magnetism can tell us about the strength and direction of the magnetic field at a certain time and location. It is also used to better understand tectonic processes. 

More field photos from the ice after we helicoptered in. ! I assisted a friend with their work, acting as a geotech as they cored lake sediments for paleoclimate studies.

What advice do you have for prospective scientists? It truly is for anyone! People from all different backgrounds find their way into geoscience.

Have you received a piece of advice from your friends/mentors/advisors that has helped you navigate your career? Don’t be in a rush. Do what makes you excited, doing it fast while stressed out helps no one.

Camping and conducting research on the ice.

Background includes the ocean and various aspects on a research vessel. The foreground has people holding a core that was pulled from the ocean floor with one person cutting a section of the core.
I’m on board a research vessel. We carried out a gravity core during an oceanographic cruise and I’m cutting the core into 1-meter-long subsections. 

I’m a marine geologist thus interested in studying of solid Earth. Particularly, my research activity is focused in studying the evolution over time of our submerged Earth system, in this case taking attention on how deep basins, forming at the rear of a mountain chains and named back-arc basins, forms and their relationships with volcanoes or magma upwelling. Over this my interest are toward the various geological risks that can affect our life and that are earthquakes 

and related tsunamis, landslides and tectonically- or climate change-controlled sea level changes. I realize these studies integrating the geophysical methods with geological information coming from sampled sediments. Geophysical methods are based on instruments (multibeam swath bathymetry, high-resolution sub-bottom profiles, single and multichannel seismic data) that allow to investigate the seafloor and the sub-seafloor rocks. The seafloor morphology in back-arc basins is more complex than one might imagine: here seafloor can reach depth over 4000 m below seafloor, and there are numerous submerged mountains that can be of volcanic- or tectonic-origin and can have dimensions sometimes huge. Between these mountains several canyons, sometimes hundred km long, flow from the coast to the oceanic deep moving enormous quantities of sediments. Deep basins or back-arc basins are formed as a consequence of the convergence between two plates or block of continents. The force generated by the convergence push the denser and heavier, even if thinner, oceanic crust to sink under the other oceanic crust (see the Mariana system) or continental crust (see the Apennine system) which, being less dense, floats. The subducting oceanic crust, called a slab, retreats as it sinks, forcing the upper continental or oceanic crust to follow it. This means that a block of crust breaks away from the continent and drifts, creating the conditions for magma to rise. The break is realized throughout the formation of discontinuities or faults generating earthquakes and, being 

submerged, the energy released is able to trigger tsunamis. Sometimes the fragmentation of rocks creates conditions of gravitational instability that trigger landslides and gas emissions. Furthermore, seismic images of the rocks have revealed particular events associated with the lowering of the sea floor during past ice eras. Identifying and analyzing the frequency, recurrence, intensity of these events in the past, and how the Earth system reacts to these thermal changes will help better constrain modeling of future global changes. All these events and phenomena are recorded within sediments, thus by drilling and sampling it we are able to identify them and date. Combining these information with the seismic images of the subseafloor and with the seabed we can reconstruct the history of submerged continental margins and of deep basins, and also do paleo-climate reconstruction. All these studies improve risk analysis and make the lives of people and animals safer. Knowing our earth system allows us to adequately protect it.

Tell us a little bit about yourself and describe your hobbies and interests outside of science. Outside of science I have a passion for dance. In my life I have practiced different types of dance: modern and jazz dance, southern dance, african dance and recently I started pole dancing. This also inspired me to create a performance that combines pole dancing with science, which speaks to the health of the sea. The pole dancer moves in a volume of air as fishes move in a volume of water. I also like fashion and art.I love cats, I love them like children and I cried a lot and I still cry for the loss of my cat named Tiger. Two years after his death I got another cat, she is female, and I am in love again.

What kind of scientist are you and what do you do? Describe what your role is and your title; this can be on the ship and/or in your current career. I am a first level researcher at the Institute of Marine Sciences – National Research Council. I carry out all the activities ranging from writing a proposal, to participating in the oceanographic cruise in order to collect data, processing, analysis and finally writing an article or presentations of results. On board I often play the role of head of mission, but I also take part in technical operations, such as deployment and recovery of the seismic system, core sampling, morphobathymetric acquisition.

Do you use proxy data for research? What are those proxy data? The paleo-morphology of the seafloor to have evidence for climate change. Foramnifera to date sediment layers and turbidites to date earthquakes. Chemism of magmatic rocks to have information on processes that occur in the earth interior.

Background is an office setting with a screen showing scientific results. The person in the foreground is pointing at this screen with results and is smiling.
I’m working in my office. I am analyzing the high-resolution image of the seabed looking for structures capable of generating earthquakes or evidence of climate changes that occurred in the past (paleoclimatic study). 

Do you conduct outreach, and if so, who do you communicate science to? Not systematically. Occasionally, I take part to events and with my dance and science performance, or a geophysical lab we have created (bathymetric maps, map of submerged risks, seismic method)

What is your favorite part about being a scientist, and how did you get interested in science? My favorite part is the beginning. When I was young, before university, I read popular magazines and one day I read about a large oceanographic ship that went out to sea collecting data to explore the depths of the ocean in order to understand the processes that allowed its evolution. I was so fascinated by it that I decided to enroll in the faculty of geology with the idea of going to sea. But I was at the university of a small city in central southern Italy, where the main studies were aimed at the tectonics of mountain systems and the seismogenic faults that had generated large earthquakes destroying several villages in the region. Towards the end of my fourth year of university I had lost hope of going to sea, but one day a professor said “there might be a possibility for some students to join a group on an oceanographic cruise. Are any of you interested?” I immediately said “I’m interested!”. A few months later I was on a ship and that was the beginning of my scientific life. But I had to leave my family and many of my friends and move from south to north Italy.

Discuss other scientific interests. I am interested in astrophysics, knowing how the Universe evolves and whether there are other life forms beyond us. This is just a curiosity and when I have the opportunity, I go to listen seminars or read some more informative articles. My legend is Margherita Hack, a great astrophysicist who loves cats.

How did you learn about scientific ocean drilling? During my work, I used data acquired during the old ODP program and thus I know of this huge and important program.

Multipart scientific figure showing a transect of drill holes, the rock sections for each drill site, and the seismic data for each drill hole. These data, together, help understand the sub-seafloor and shape of the sea floor.
This figure is a summary of my work. I integrated the analysis of geological data derived from wells drilling with seismic images of the sub-seafloor and the morphology of the seabed. 
 

 How does your work contribute to the betterment of society in general? Through the analysis of how the mantle rises, how faults control the exhumation of the mantle, how fluids circulate along fault planes influencing block movements, how faults can rupture generating earthquakes, the recurrence and the sliding of blocks. All this helps us to better understand the evolution of the Earth and evaluate its geological risks.

Are you training the next generation of scientists? I train students through curricular internships, graduate thesis and doctoral students.

What advice do you have for prospective scientists? Be passionate, courageous, opened, positive, build good relations and try to fly to go where your scientific imagination tells you to go, but at the same time be rigorous.

Have you received a piece of advice from your friends/mentors/advisors that has helped you navigate your career? Become an expert in an area and build your skills so that you become strong in your research area.

Tell us a little bit about yourself, describe your hobbies and interests outside of science. I like to hike with friends, mountain bike, climb, football, basically all kind of sports that imply being outdoor in the mountains. In Germany, I trained a football team of international students and we played a European tournament in Athens (Greece).

What kind of scientist are you and what do you do? I am a PostDoc researcher in Marine Geology, especially focusing on i) mud volcanoes, gas- and mud-spewing structures similar to magmatic volcanoes; and ii) paleoseismology, studying the effect of extreme events related to earthquakes on the sedimentary archive of the ocean seafloor. In a sense, I am using i) mud volcanoes as deep boreholes to explore the interior of subduction zones (unreachable through scientific drilling), by analyzing their sediments’ / fluids’ geochemical and mineralogical composition; and ii) event deposits to reconstruct the paleoseismic history of a certain region.

Background includes research and mechanical equipment on a scientific research vessel. Foreground includes a person trying on a bright orange thermal immersion suit while smiling.

Do you conduct outreach, and if so, who do you communicate science to? I am trying to convey my science to the general public through diverse media (radio podcasts, news magazines, conferences/talks), in order to explain the societal application (and relevance) of what can be seen as quite abstract such as scientific research.

What is your favorite part about being a scientist, and how did you get interested in science? I started as and onland geologist as a university student due to my love for the outdoors and evolved into a marine geologist. I did not know anything related to marine geology until my PhD. I like basically everything that has to do with scientific innovation and green-energy, plus I am fascinated by biology.

How did you learn about scientific ocean drilling? If you are a marine geologist you should know the history of DSDP-ODP-IODP by heart 😉 I also participated in a previous IODP expedition.

How does your work contribute to the betterment of society in general? Subduction zones are where all the most destructive earthquakes (Mw>8) happen on earth. Nonetheless, several aspects of these complex geotectonic settings still remain obscure. Through the study of mud volcanism and paleoseismology I am trying to understand fluid and solid cycles in subduction zones, which play a role in their evolution and record past earthquakes. Understanding the seismic hazard coming from subduction zones and informing the population and the stakeholders on the risk implicated is key for an effective risk management.

View is from an aerial perspective so the background is the base of the ship deck, wooden planks. The person in the foreground is securing a piece of equipment used in pulling rock core up out of the ocean and onto the vessel.

Are you training the next generation of scientists? I am advising several PhD/MSc/BSc students, and I taught university courses/gave seminars to future scientists in the past.

Do you engage in community science? Whenever I discover something new on the seafloor I try to involve the local population in taking part with the naming process of the features.

What advice do you have for prospective scientists? It is above all a vocational path, in particular marine geoscience. I was born in the Italian Alps and could never have imagined that I would love being on a research vessel so much. Nothing will forge you better as a scientist then your motivation and drive for knowledge.

Brandon was helping retrieve seismometer instruments that traveled all the way down to the seafloor and recorded geophysical data to understand earthquake hazards along the Middle America subduction zone.

Tell us a little bit about yourself. I grew up in Colorado along the foothills of the Rocky Mountains. I am passionate about the outdoors and spending time in nature. In my free time, I enjoy skiing, mountain biking, hiking, paddle boarding, disc golf, fitness, and cooking. I recently got into BBQing (smoked meats and veggies), and various fermentation projects (kombucha and fermented hot sauce).

What kind of scientist are you and what do you do? I am a solid-earth geophysicist and my research lies at the intersection of tectonics, geophysics, structural geology, and basin analysis. I am interested in the structure and evolution of the Earth’s lithosphere at tectonic plate boundaries. I primarily use active-source geophysical data to indirectly image the properties of rocks deep in the subsurface that we cannot “see” otherwise. I get excited about using new technology to make stronger connections between tectonic processes and the geologic record. My research studies processes in the Earth’s lithosphere on both geologic time scales and human time scales. Tectonic plates move very slow, so it can be challenging to think about dynamics that take place over millions of years! I am also interested in geology on human time scales, such as earthquakes, volcanic events, and the role of geosciences in providing energy for our society. 

What is your favorite part about being a scientist, and how did you get interested in science? I got interested in geology at a young age growing up in Colorado Springs where I was naturally curious about strange rock formations, such as the vertical sedimentary rocks in the Garden of the Gods. I decided to attend Western Colorado University, a small school in Gunnison, Colorado. In the Western geology program, I was exposed to the incredible rock formations and was fascinated by the stories they told about Earth’s past. I also became interested in mathematics and ended up getting a double major in geology and math. After graduation, I wanted to combine geology and math which led me into geophysics and PhD studies at UT Austin. At UT, I was fortunate to participate in several marine field expeditions that got me very excited about sea-going research and all the amazing tectonic processes happening in the Earth’s oceans. What I love most about my work is the feeling of exploration and discovery and contributing to our knowledge about some of the remote areas of our planet. 

How did you learn about scientific ocean drilling? I first came across scientific ocean drilling in graduate school where I was learning about the history of Plate Tectonic theory. I was amazed at how much we could learn by sampling rocks in the oceans where we cannot easily “see” them like rocks on land. I am very grateful to participate in a scientific ocean drilling expedition and contribute to the legacy of the program. 

How does your work contribute to the betterment of society in general? My research helps us better understand aspects of plate tectonics that we still have outstanding questions: How do continents break apart and form new oceans? How do subduction zones initiate and terminate? Why do some faults break in large earthquakes and others release energy slowly? I am passionate about sharing the joy of geosciences with the public. General knowledge of the geosciences is important for many pressing problems in society: climate change, energy industry, life on earth, and hazards such as earthquakes, volcanoes, and tsunamis. Nearly 40% of the global population lives within 100 km of the coastline where there are many geologic processes that can affect their lives. I hope that my research on geologic hazards at tectonic plate boundaries will help strengthen our societal resilience to these events and better understand the risks and threats to various communities.

Hanging out on folded rocks in Crete, Greece. This outcrop is famous for its beautiful Chevron-style of folds evident in the deformed “zig-zagging” rock layers. The angled fold limbs made for a perfect spot to relax after spending time looking at the rocks in detail.

 What advice do you have for prospective scientists? Anyone can do science! I had a non-traditional background into science and was a bad student in high-school. At that time, I would never have thought I would be capable of getting degrees in geology and mathematics and doing science for a living! It turns out that success in academia is really about good mentorship and finding what you are passionate about. Just because you were not good at something does not mean it will always be that way. I am fortunate to have had a lot of amazing mentors and teachers along my journey that were patient, supportive, and gave me unwavering encouragement. Don’t fear the failures (which are inevitable), but instead stay determined and follow your dreams.

How did you get into science? I’m a first generation student who grew up in rural East Tennessee and unfortunately didn’t have a great science education heading into college. I didn’t know science was something I liked and could be good at until college and graduate school was never on my radar. I found geology through my love of rock climbing, and luckily had a professor offer to let me tag along on some field work, which kickstarted my research career. That same professor later encouraged me to apply to grad school and helped me through the process.

How did you learn about scientific ocean drilling? My advisor sailed on Expedition 396, and I’ve been working on samples from that expedition for the past two years.

What is your role on the ship? I study lavas that come from the Earth’s mantle to see what they can tell us about what the mantle is made of since we can’t directly sample the mantle or go see it.

Do you use proxy data in your research? Using the geochemistry of basalts (the type of lava typically erupted on the ocean floor) to deduce what the mantle is made of is a type of proxy work, but it’s quite tricky. There’s still so much we don’t know! I’ve developed numerical models to help constrain the possible chemical make-up of mantle source rocks based on the composition of lavas erupted at the surface.

How does your work contribute to the understanding of our Earth? Continental rifting is a primary tectonic process and major shaper of the Earth, yet it’s still not fully understood. My research tells us about what the Earth’s mantle is doing throughout the rifting process and if/how the mantle conditions control the type of rifts produced.

How are you training the next generation of scientists? My university has a great program called the Undergraduate Mentor Development Program which allows graduate students to be certified mentors for undergraduates interested in doing research. I completed the program my first semester as a Ph.D. student and have been mentoring the same undergraduate student since my second semester. It’s so rewarding to see how excited she gets about science and it’s been great to see her grow as a scientist.

Do you conduct scientific outreach? I spent last semester in a local high school working with geology and biology classes to help bring my science to them, but also to observe and learn from their teachers how to best communicate science to teenagers.

What are your hobbies and interests outside of science? I enjoy reading and outdoor recreation, especially climbing and skiing.

Is there anything else about yourself you would like to share? I do it all for my dog and two cats.

What advice do you have for prospective scientists? Science is for everyone! Scientists are often portrayed in the media as stuffy old dudes that take themselves way too seriously, but we’re just normal people with a lot of curiosity about the world around us.

Fake it until you make it is a big one for me. Imposter syndrome is real, and sometimes it helps just to keep in mind that a lot of people feel like they’re faking it when from the outside they’re obviously crushing it.
