The Importance of Marine Scientists
Water is the planet's most vital resource, and marine scientists are essential to understanding and protecting the vast and complex ecosystems that exist within our oceans and waterways. Their expertise spans various disciplines, including biology, chemistry, geology, and physics, enabling them to study everything from the smallest microorganisms to large marine mammals.
Marine scientists conduct research on everything from ocean currents to rising sea levels, ocean acidification, marine biodiversity, to changing marine life patterns, and the effects of pollution, climate change, and human activity on marine environments.
Given the oceans' role in regulating global climate, producing oxygen, and providing sustenance for billions of people, the importance of marine science is immense. Despite their significance, much of the ocean remains unexplored, with scientists estimating that over 80% is still unmapped and unobserved. This knowledge gap poses challenges in understanding the full impact of environmental changes and in devising strategies to protect marine ecosystems.
Career Paths in Marine Science
Marine science offers diverse career paths, each focusing on different aspects of ocean ecosystems. These fields allow scientists to specialize in particular areas of study, contributing to a more comprehensive understanding of the marine environment. Among the most prominent fields are the four main branches of oceanography and marine biology.
Biological Oceanography: Studies relationships between marine organisms and their environment, focusing on how biological processes are influenced by factors like currents, temperature, and light.
Chemical Oceanography: Investigates the chemical makeup of seawater and the processes controlling it, including the movement of elements like carbon and nitrogen. Key to understanding ocean acidification and the carbon cycle.
Geological Oceanography: Explores ocean floor structures, such as ridges and trenches, and the processes shaping them. This field also examines sediment deposits to uncover Earth's geological history.
Physical Oceanography: Examines the ocean's physical properties - temperature, salinity, waves, and currents - focusing on their impact on climate, weather patterns, and marine life movement.
Marine biologists differ somewhat from biological oceanographers, as they study animals, plants, and microorganisms that inhabit the ocean, with a particular emphasis on understanding their life cycles, feeding habits, and interactions with other species. Unlike biological oceanographers, marine biologists are primarily concerned with the organisms themselves rather than the broader environmental context.
Tools and Technologies of Marine Science
Ocean study can be quite complex and varied, requiring many different types of data to paint an accurate picture of these environments. Because of this, marine science relies on a variety of specialized tools to collect data, analyze samples, and conduct experiments in challenging ocean environments.

These tools are used in both coastal and deep-sea environments, contributing to marine research and conservation efforts.
Moorings
Moorings are structures used in marine science to secure instruments and sensors at specific locations in the ocean. They consist of anchors, chains, and buoys that keep the instruments in place, allowing for the continuous collection of data over extended periods. Moorings can support various sensors, such as those measuring temperature, salinity, and currents, and can also facilitate the transmission and reception of acoustic signals. This capability enables real-time communication with deployed instruments, enhancing the ability to monitor and analyze marine environments.
Profilers
Profilers are specialized instruments used to measure and collect data on various environmental parameters as they descend and ascend through the water column. Typically deployed from a ship, profilers can be programmed to reach specific depths or descend all the way to the seafloor. During their descent and ascent, they gather data on variables such as temperature, salinity, and pressure, providing a comprehensive vertical profile of the water column. This data is key for understanding oceanographic conditions, tracking changes over time, and informing models of ocean circulation and climate.
Acoustic Technologies
Acoustic technologies are vital for mapping and monitoring underwater environments. They include:
Acoustic Doppler Current Profilers (ADCPs): Measure water currents by analyzing Doppler shifts in reflected sound waves, offering real-time data on ocean flows.
Sonar: Maps the seafloor by emitting sound waves and recording their reflections, providing detailed images and topographic maps for navigation and geological studies.
These technologies improve our understanding of marine dynamics and support a broad range of oceanographic research.
Remotely Operated Vehicles
ROVs are unmanned underwater robots controlled from the surface, equipped with cameras, sensors, and manipulative arms. They are crucial for deep-sea exploration, enabling access to extreme depths and facilitating:
Species and Habitat Monitoring: Observing and documenting marine life and ecosystems.
Sampling and Water Quality Analysis: Collecting samples and analyzing water properties.
Seafloor Mapping: Creating detailed maps of underwater topography.

The institute is thrilled with their decision, finding the ROV to be an effective tool in engaging the public and enhancing the educational experience on the tours.
As noted by McGuire, “this is such a great way for our guests to see below the surface. I like to call it ‘virtual snorkeling.’ We get people in the water, in the virtual sense, and it streams footage live to all of the screens. It’s so cool to see the looks on everybody’s faces when they see this underwater habitat right in front of them.”
Hands-On Learning and Engagement
The boat tours are designed to engage diverse groups, including young students and community members. They were initiated to help the public appreciate the importance of local marine habitats and the research conducted on them. McGuire explained, “Our experience is truly one-of-a-kind. Not only do we get up-close and personal with the animals and habitats in the lagoon, but our guests get to learn about the research we are doing right here in our own backyard!” This approach allows participants to connect with the underwater environment in a tangible way.The tours include hands-on educational experiences. Students and community members can use scientific tools such as secchi discs, handle live specimens like jellyfish, and observe various equipment in action, including collection nets and moorings. The interactive elements are designed to spark curiosity and inspire future interest in marine science and STEM careers. As McGuire reflected, “It’s amazing when you get young kids on the tour. They get so excited about what they’re seeing, and I love getting the chance to teach them all about it. That’s something they’re going to remember forever.”
Fostering Environmental Stewardship
The impact of the tours extends beyond just education. By creating environmental stewards, the program encourages participants to advocate for and protect marine ecosystems.
“The investment in educating all these people on the lagoon and creating environmental stewards to go out in their community and really care about the environment that they’re in” highlights the broader goal of fostering community engagement and conservation.
A notable educational moment from the tours involved the ROV spotting a lionfish, an invasive species. As described by McGuire, “my favorite thing that I saw with the ROV was a lionfish in our channel. We saw it three days in a row which was really cool, but it was such an important thing to talk about because it’s an invasive species. The problem is they eat everything, but nothing eats them, so they can wreak havoc on these environments. It was a really great teaching moment.”
Samantha McGuire explains concepts and sights seen along the way, many from the underwater video output of the ROV, on the immersive boat tour.
