What are Ocean and Earth Sciences?
Ocean and Earth Science is a broad field that studies the entire Earth system, including the land, oceans, atmosphere, and the Earth’s interior, and how they interact. It encompasses various disciplines such as geology, geophysics, environmental geoscience, oceanography, and marine biology. While elements of these topics might be covered in school subjects like geography, physics, chemistry, and biology, they are not always explicitly labelled as Earth or Ocean Science. Earth Science specifically focuses on areas like past climate change, geohazards (earthquakes and volcanoes), sustainable resource use, plate tectonics, fossils, and applying scientific principles to engineering, pollution remediation, and carbon capture. Ocean Science is distinct but closely connected, focusing on the processes within the oceans and their impact on climate and marine life. This includes oceanography (studying currents, climate patterns, sea level change, ocean chemistry, and pollution) and marine biology (focusing on the physiology, ecology, and genetics of marine organisms from the deepest oceans to coastal areas, including coral reefs, fisheries, and plankton).
What sparked Professor Lisa McNeill’s interest in this field?
Professor Lisa McNeill initially studied natural sciences as an undergraduate without a specific plan to go into geology. However, she had a childhood interest in natural history, collecting things like fossils, feathers, and butterflies, and was interested in various science disciplines. Studying geology as part of her degree captured her interest due to the opportunity to understand the planet, the appeal of working outdoors and participating in field trips, and the way it combined her interest in the environment with various science disciplines. This led her to specialise in geology, and she notes that many students drawn to Ocean and Earth Science have had similar long-standing interests from childhood.
What are some traditional career paths in Ocean and Earth Sciences?
Traditionally, careers in Earth Science (specifically geology) have included roles in the oil and gas and mineral sectors. However, the field offers much more. Other traditional areas include engineering geology, hydrogeology (the geology of water systems), geotechnical surveying (using physics to image below ground), environmental consultancy, cartography and hydrographic surveying (mapping land and seafloor), assessing and mitigating geological hazards (including roles in observatories, insurance companies, and government agencies), research, working with water companies, construction companies, and in museums. Traditional areas in Ocean Science have included environmental consultancy, meteorology and climate modelling, conservation (biodiversity, charities), working in fisheries or ecology, surveying, government agencies and labs, and aquaculture.
What are some emerging and high-impact career opportunities in Ocean and Earth Sciences?
Beyond traditional roles, the field is seeing increasing opportunities, particularly driven by environmental challenges. High-impact careers include environmental consultancy focusing on pollution remediation, sustainably identifying and extracting mineral resources needed for technology (like mobile phones, electric cars, and solar panels), assessing and reducing the impact of sea level rise and coastal erosion, marine conservation and addressing pollution in the oceans, and exploring the potential of marine organisms and their chemistry for medicine and pharmaceuticals. Additionally, due to the large data sets and complex technologies used, graduates in these fields are increasingly finding roles as data scientists and even in the finance sector, leveraging their quantitative and scientific skills.
What are the main challenges in Ocean and Earth Sciences, and how are they being addressed?
Professor McNeill primarily views the current situation as one of opportunity rather than challenge, focusing on how the field can help address the environmental challenges facing the planet. However, she does highlight one practical challenge: the need for students to maintain interest and knowledge across various science disciplines. Studying Ocean and Earth Science often requires a broad understanding of physics, chemistry, and biology. Encouraging and supporting children to maintain their studies and skills in a range of sciences can be a challenge, especially when they have diverse interests. Having said that, most university programmes in these disciplines will provide introductory modules covering the basic sciences to ensure all students are at the level required by the end of the first year.
The field is addressing global environmental challenges by focusing on sustainable resource use, understanding and mitigating climate change impacts, and developing solutions for pollution and coastal erosion.
How will technology, including AI and robotics, transform the future of Ocean and Earth Sciences?
Technology is already significantly impacting Ocean and Earth Sciences and its role is expected to grow. Robotics are used for exploring the ocean, with autonomous vehicles collecting detailed data from the seafloor and gliders gathering vast amounts of ocean data. Research vessels are likely to become increasingly automated in the future. Satellites are also crucial for data collection across the Earth’s surface and interior. These technologies generate massive and complex data sets. Artificial intelligence (AI) is becoming increasingly important for interpreting these large data sets in both research and industry, helping to extract answers and insights.
Students at the university level are already learning and using these tools. The increasing need for skills in programming and handling large data sets will be a major driver of change in the field.
What essential skills should students develop to prepare for careers in Ocean and Earth Sciences?
Beyond a broad interest in science, several key skills are important. Curiosity about the world and the environment is fundamental and should be encouraged. Developing strong skills and interests across different science disciplines (physics, chemistry, biology) is beneficial. Gaining a head start in computing skills, including maths and coding, is very useful as the field relies heavily on data analysis and technology. Reading about the subject in various forms, such as news, social media, blogs, TV, and science magazines, helps to illustrate the applications and importance of these fields. Any opportunities for work experience are also valuable.
What resources and activities are available to spark interest and learn more about Ocean and Earth Sciences?
There are various resources and activities available to engage with Ocean and Earth Sciences. Looking for websites and links that provide information about the subjects and related resources is a good starting point. Attending festivals of science, open days at universities and institutions focusing on Earth science or marine science can be inspiring. These events often cover engaging topics like fossils, dinosaurs, volcanoes, and marine life. Examples include events like British Science Week in the UK, which offers activities for all ages. Visiting museums, especially natural history and science museums, provides opportunities to see collections and learn about current projects. While online resources are helpful, experiencing and seeing things in person at local opportunities like science festivals and museums can be a key way to spark interest and passion for the subject.
