Samantha Jones is a Ph.D. Candidate in the Department of Geography at the University of Calgary studying carbon cycling in the Canadian Arctic. In addition to her scientific work, Samantha is also a poet, published writer, and workshop instructor at the Alexandra Writers' Centre Society in Calgary. Samantha recently wrote a poem suite, "Ocean Acidification" (published in Watch Your Head, March 2021) that uses visual poetry to educate and help people form a connection with ocean acidification. Samantha shares with us her creative process, scientific background, and her interests in combining science and poetry. What is your background? I am a geologist by background. I completed a BSc (Hons) in Earth Sciences at Dalhousie University and an MSc in Geology at the University of Calgary. I moved to Calgary in 2006 for an industry internship and graduate school and then remained in Alberta to work as a petroleum geoscientist. After a maternity leave, I returned to university to start my PhD in geography with a focus on climate and carbon cycling in the Canadian Arctic. My current research investigates carbon dioxide exchange in a connected lake – river – coastal ocean system in Iqaluktuuttiaq (Cambridge Bay), Nunavut. I am particularly interested in seasonal variations and high-temporal resolution cycles. Now, let’s talk poetry! I have always wanted to be an author. As a child, I was an avid reader and I always dreamed about seeing my own works on bookstore shelves. While I was working in industry, I was able to complete continuing education courses through the University of Calgary and I earned a certificate in Creative Writing. This was the beginning of carving out some serious time and space for my creative practice. A big part of my writing journey has been seeking and establishing community. I am a three-time alumna of the Iceland Writers Retreat and an alumna of the Banff Centre. In 2020 and 2021, I expanded my presence in the Canadian Literary scene by founding and facilitating the Diverse Voices Roundtable and Writing Circle for BIPOC writers at the Alexandra Writers’ Centre Society (Calgary, Alberta), where I also teach writing workshops. I regularly publish in literary magazines both online and in print, and my writing is included in three anthologies. What motivates/inspires you to combine science and poetry? I am interested in the natural world, in particular everything earth and geoscience related. Environmental themes recur in my work, as well as places that evoke these themes. My poetry often takes me back to locations that I visited during my training as a geologist and with my family on rockhounding or birding trips. I enjoy talking about scientific themes in poetry because it grants me permission to let my emotional self be present in the work, which is not typical in academic writing. This is particularly useful when writing about environmental challenges because it invites the reader into understanding through personal connection. Poetry has an ability to perform scientific processes on the page. At present, I am working on a new project that embeds scientific data into the structure of poems. There is lots of exciting work to be done in blending science and poetics. What inspired you to write about OA in particular? OA is an interesting topic to write about because it is lesser-known compared to other climate issues. I like the idea of exploring something that is invisible in a sense, but poses a substantial threat. I think OA deserves more attention and public awareness and I was confident that writing about the topic would land it in front of audiences that were previously unfamiliar with the phenomenon. Writing my recent poem “Ocean Acidification” (published in Watch Your Head) was a unique opportunity to write a piece that bridged the divide between the scientific and literary communities that I operate within. I am drawn to writing about the scientific topics I know well because although fact checking is still required, I have largely completed the research through my daily work and I am able to get the story onto the page with a relatively uninterrupted flow. What was your creative process in writing these poems? I started with the idea for the visual elements in “Ocean Acidification” and I began writing by drawing six circles, which would then become a constraint for the text. I wanted the poem to explain OA, or at least provide enough information that someone could seek out additional resources on the topic. In addition, I wanted to take the reader from the first circle, which represents both an intact system and the healthy bodies of organisms that build carbonate shells, to a diminished and disappearing version of what was once real. The progressive dismantling of the circles was a way to perform OA on the page. I also used erasure poetry techniques to progressively remove text and alter the narrative to mimic dissolution. How did you want people to interact with these poems? You can interact with the “Ocean Acidification” poem in different ways. If you are listening to a recording, you will get the narrative. If you read the poem on the page, you will get the narrative and view the text performing the OA process. You can also unfocus your eyes and get the take-home message from the overall visual elements in the piece. Is there a take-home you hope those who read your poems are left with regarding OA? I hope people are interested to learn more about OA and the challenges that it poses. I also hope that this work helps demonstrate that there are many avenues for science communication and that creative outputs and deliverables should be afforded the same value as scientific contributions. How have you found the reception of these poems to be? Have you learned anything new/interesting/unexpected from the experience? The interest by the scientific community to “Ocean Acidification” was moving. There were people all over the world and at all stages in their careers reading the work, which gave my voice a broad reach. It was cool to be able to get people from different areas of my life together in the same space through social media to enjoy the poem together. It was obvious that there is a thirst for this type of content and that continuing to produce science poetry is something that is of interest to multiple communities. What is one thing you hope scientists take away from your creative works? One of my key messages is that science and creative pursuits like poetry or art are not separate. Scientists are inherently creative and innovative and I hope to contribute to a space where people feel comfortable taking risks and engaging in creative practices. What excites you most about combining data and poetry? I love the idea of combining scientific processes and data with poetry because I think that it prompts me as the writer to interrogate data differently. When I write “data poems” I need to think carefully about how I want to visualize the data on the page through the narrative or visual elements. The product is something that could not have existed without the data and scientific knowledge or the poetic practice. The generated poem is a new entity that uses both science and art inputs equally. Anything else you’d like to say? Just that intuition is a very powerful thing. If you have a dream or an idea that you think could be unique, take some time to explore it. Wonderful surprises can grow from interdisciplinary seeds.

Early career (PhD) positions for research into ocean alkalization and CO2 uptake "Join a diverse team studying how the addition of alkalinity, produced during production of clean hydrogen fuel, can enhance the ocean’s uptake of CO2. We are recruiting a team of early career researchers (including up to 4 PhD positions) with interest in environmental chemistry (#1 and 4 in figure), aquatic biology (#2-4), and marine physics (#3) to work within a unique, multidisciplinary team. The team will investigate the efficacy and impact of adding alkalinity to coastal seawater in order to increase the ocean’s capacity for removing CO2 from the atmosphere. The research will contribute to development of Planetary Hydrogen's innovative co-production process, which aims to produce H2 as a clean fuel while decarbonizing our economy and contributing to Canada’s greenhouse gas reduction commitments under the Paris Agreement. For more details, please contact the supervisors individually or contact the entire project team at: oceans@planetaryhydrogen.com Supervisors: Douglas Wallace; Hugh MacIntyre; Ruth Musgrave; Jeff Clements; Ramon Filgueira Partners: Planetary Hydrogen L'Étang Ruisseau Bar Ltée Fisheries and Oceans Canada Project Description and Opportunities Hydroxide ion, generated as a byproduct of a novel process of hydrogen generation, can be used to increase the ocean’s ability to take up and store atmospheric CO2 in the form of dissolved bicarbonate. This alkalinity addition mimics the natural geochemical weathering reactions that have created the ocean’s massive reservoir of bicarbonate and carbonate ions, and can potentially benefit organisms that are vulnerable to ocean acidification, including commercially important shellfish. In collaboration with Planetary Hydrogen and with support of two major philanthropic foundations (Climateworks and Thistledown, we are assembling a multidisciplinary team of researchers to investigate this promising negative emission technology. The team will include 4 PhD candidates working on chemical, physical, and biological oceanography, and animal (bivalve) physiology. The doctoral candidates will work within a larger group that will include experienced postdoctoral researchers, technicians, undergraduate students, and summer interns from Dalhousie University’s Imhotep Legacy Academy. The team will have access to specialized training and research collaboration with groups in the USA and Germany. The project is led by professors at Dalhousie University, researchers at Canada’s Department of Fisheries and Oceans, as well as personnel from Planetary Hydrogen and a commercial oyster hatchery (L'Étang Ruisseau Bar Ltée). We are initially seeking PhD and/or Masters candidates in the following areas. (Note: candidates interested in postdoctoral research opportunities should also contact us). Marine chemistry: Alkalinity impacts on seawater chemistry, including field-scale studies with autonomous vehicles. Supervisor: Douglas Wallace Background in environmental chemistry and strong laboratory skills; interest in use of robotics and sensors for field measurement of chemical properties Ability to program (e.g. with Python or R) is a significant asset Biological Oceanography: Impacts of alkalinity addition on phytoplankton viability and growth. Supervisor: Hugh MacIntyre Strong quantitative skills Preferably, experience with culturing microorganisms and/or relevant analytical techniques (chlorophyll fluorescence, biochemical analyses of biomass composition) and data management Ability to program (e.g. with Python or R) is an asset. Physical Oceanography: Prediction and field validation of upper ocean turbulence and diffusivities. Supervisor: Ruth Musgrave Undergraduate degree in physics or mathematics, and an interest in interdisciplinary work; Experience with programming (Python, Matlab, R, Julia, or equivalent), numerical models, fluid mechanics and oceanography will be advantageous. Bivalve Ecophysiology: Supervisors: Jeff Clements; Ramon Filgueira; Undergraduate degree in biology with a background in marine biology, and experience designing and conducting laboratory experiments; Ability to program using R or Python, and a working knowledge of ectotherm physiology, will be considered assets. Training Environment The early career researchers will work within a highly interdisciplinary team, with both national and international collaborators from academia, industry, and government. In addition to the training provided by Dalhousie University, members of the team will participate in regular workshops offered by team-members, covering topics such as planetary carbon cycle; algal and animal physiology; marine robotics; sensor design and operation; negative emission technologies; coastal modelling; Canada’s hydrogen economy, and career-related topics including entrepreneurship and business development practices. All of these positions will require candidates to have the ability to work independently but also within a coordinated and collaborative lab group. This requires a sense of responsibility to the team as well as good communication skills. Our research group is already diverse and international, and we are committed to increasing this diversity as we recognize this strengthens the research environment and maximizes potential. We are therefore committed to a fair hiring process and employment equity practices that are consistent with Canada’s Employment Equity Act.

Fiona Beaty is a Ph.D. Candidate in the Zoology Department of the University of British Columbia studying marine ecology and conservation in the Salish Sea. She is also a National Geographic Explorer and UBC Public Scholar. Fiona shares with us her background and research interests in ocean acidification, as well as her interdisciplinary work to understand how coastal ecosystems and human communities are responding to global change. What is your background? I am a marine ecologist and conservationist. My passion is learning how marine life in the Salish Sea is responding to climate change and connecting this knowledge with policy and adaptation strategies to protect both life in and human connections to the ocean. I am a true interdisciplinarian at heart - it is very hard for me to pick just one topic to learn about! Accordingly, my research interests range from a curiosity about the mechanistic physiological and evolutionary responses of marine invertebrates to ocean warming and acidification, to a fascination with how coastal communities value and want to protect the ocean, to an obsession with using maps as a way to engage decision-makers and communities in marine spatial planning and conservation. In pursuing these research interests, I have developed skills within both the natural and social sciences, such as leading manipulative field and laboratory experiments, quantitative meta-analyses, and community-based research (e.g. interviews, survey, participatory mapping). Most recently, I am grateful to be learning about ways that I, as a settler, can co-create knowledge in partnership with the Indigenous community on whose lands and waters I reside and study – the Squamish Nation. My work history includes over five years of working with multiple non-profits that lead marine restoration and conservation work within the Salish Sea. Through this experience I have learned effective ways to connect research to marine policy and conservation outcomes and strengthened my collaborative leadership skills. What is your interest or background in OA? I first learned about ocean acidification prior to starting graduate school; however, it was not until I began studying it in detail that its ramifications for the health and well-being of marine life truly hit home. I remember realizing one day that ocean acidification to a calcifying marine invertebrate is analogous to the air around us becoming so polluted that our skin starts to dissolve. This horrifying realization changes the way that I breath and move around every time that I think about it. The analogy between the chemical alteration of air and water due to growing carbon dioxide emissions feels particularly relevant each summer when the city where I live experiences air quality warnings due to wildfires. Last year the effects of wildfire smoke compounded the existing health effects we experienced due to the coronavirus pandemic. Both wildfire smoke and the virus target our respiration systems, which means that being afflicted by one could potentially exacerbate the severity of the other – a very daunting prospect indeed. This experience was the perfect elucidation of how multiple stressors can interact with one another to alter the overall sublethal and lethal impacts to individual health. If we dive back into the ocean, we realize that many marine organisms are experiencing numerous simultaneous changes to their abiotic environment, including rising seawater acidity, rising temperatures, decreasing oxygen levels, altered salinity patterns, increased pollution, and altered light and noise levels. I wrote a piece on this analogy between wildfire smoke, COVID-19, and ocean acidification for The Narwhal this past summer (read it here). How these pressures, particularly ocean acidification and warming, interact with one another to affect marine invertebrates is the core focus of my research. Can you tell us about your past or current contributions to OA research? My ocean acidification research falls under two distinct research questions. First, I am interested in testing how evolutionary processes, such as local adaptation and plasticity, impact marine invertebrate responses to ocean warming and acidification. This research can shed light on the adaptive potential of organisms who live in areas of rapid environmental change, such as the Strait of Georgia in British Columbia. To this end, I have used laboratory and field experiments to test the response of two populations of an intertidal snail, Nucella lamellosa, to these climate-linked stressors. The results indicate that the snails who live in the Strait of Georgia, an inland sea with rapidly warming water that fluctuates drastically in acidity, have likely already exceeded their adaptive optima. This means that future environmental changes may push these populations beyond their physiological limits, compromising their fitness and local persistence. I presented this research during the Western Society of Naturalists conferences in 2018 and 2019, abstracts available here and here. My second research inquiry is compiling what we know about the overall and interactive sublethal and lethal effects of ocean warming and acidification on marine ectotherms. Specifically, I am interested in how these effects vary across taxonomic groups, such as crustaceans, fish, and corals. To answer this question, I am leading a meta-analysis of factorial laboratory experiments that test the response of marine ectotherms to these two climate-linked pressures. This research is currently in progress. I presented a poster at the Western Society of Naturalists conference in 2020, available here. What do you see as the most pressing OA issue for Canadians? Canadians need to understand that ocean acidification is an eco-equity issue: carbon dioxide emissions that dissolve into the water disproportionately affect the survival and well-being of specific marine organisms, such as shell-growing plankton and marine invertebrates. Juvenile invertebrates are particularly vulnerable to corrosive seawater, which can lead to reduced survival of culturally and economically important marine animals, such as mussels, oysters, and abalone. In turn, these lethal impacts disproportionately affect coastal communities whose food security and livelihoods depend upon a healthy ocean. For example, many Indigenous and remote communities rely on marine invertebrates for their diet, culture, and income. In addition, shellfish aquaculture facilities, which are often small family-run businesses, are facing immense challenges in maintaining and growing shellfish stocks due to ocean acidification. Overall, Canadians need to immediately mitigate carbon emissions and support adaptation strategies that protect the health and abundance of marine life, and the well-being of coastal communities. What is the one take-home about OA that you wish all Canadians knew? I wish that more Canadians knew that coastal ecosystems play a huge role in the fight against ocean acidification and climate change. In addition to providing critical habitat, seaweeds and seagrasses can create local ocean acidification sanctuaries for vulnerable marine invertebrates. They do this automatically when they photosynthesize: absorbing carbon dioxide and releasing oxygen substantially reduces seawater acidity within kelp forests and eelgrass meadows. While this buffering effect is localized and can diminish overnight when the plants switch to respiration, the daily relief it provides to marine invertebrates is critical to building ecological resilience to ocean acidification. In addition, coastal ecosystems, such as seagrasses, salt marshes, and mangroves, can store carbon in their tissues and sediments, thus contributing massively to global carbon sequestration. In fact, these coastal plants can capture and store more carbon per unit area than terrestrial forests! This is called blue carbon. Overall, marine plants play a critical role in maintaining the health and resilience of marine life in the face of ocean acidification and climate change, and need to be protected by Canada and all coastal nations. What excites you most about the current or future of OA research in Canada? I am grateful that public awareness about ocean acidification is growing. Several years ago, I feel that many people had never heard of nor understood what ocean acidification was. Now, thanks to the work of science-communication and research champions throughout the world, many more people understand that ocean acidification is directly linked with carbon emissions and is a substantial threat to marine life that requires urgent attention by policymakers. I am also excited that experimental studies about ocean acidification are becoming more rigorous. A decade ago, many ocean acidification experiments manipulated seawater by dumping acid into the water and tested unrealistic acidity levels that far exceed global projections (e.g. seawater below pH 7.0). Now, nearly all lab experiments manipulate seawater by bubbling carbon dioxide into the water (an exact simulation of ocean acidification). In addition, more data is available on local ocean acidification projections, which enables researchers to directly test how organisms will respond to ocean acidity levels that their specific region will experience within the next century. Both of these factors improve our understanding of the shifts and transformations that ocean acidification will cause to marine ecosystems throughout the world, which strengthens our ability to prioritize adaptation strategies and resources to the species and communities who are most vulnerable to climate change.
