Learning about these areas helps Scouts understand how the ocean connects to many parts of our world.

Why Learning About the Oceans is Important

The Oceanography merit badge helps Scouts learn why oceans are essential to the Earth. Here are some reasons why studying the oceans matters:

• Oceans cover 70% of the Earth: Most of our planet is ocean, so understanding it is vital.
• Oceans drive weather and climate: They influence storms, rain patterns, and global temperatures.
• Oceans provide food: Fish and other seafood are a major food source for millions of people.
• Oceans produce oxygen: Phytoplankton, tiny plants in the ocean, create much of the oxygen we breathe.
• Oceans support transportation: Ships use the ocean for trade and travel.
• Oceans store carbon: This helps reduce the impact of climate change by absorbing carbon dioxide from the atmosphere.
• Oceans hold energy resources: Wind, waves, and tides can produce renewable energy.
• Oceans are home to unique ecosystems: Coral reefs, deep-sea trenches, and other habitats are rich in life.
• Oceans provide medicine: Some marine organisms are used to make new drugs.
• Oceans connect the world: They link continents and cultures, supporting trade and communication.

By learning about the ocean through the Oceanography merit badge, Scouts gain knowledge that helps them appreciate this vital part of the Earth and take steps to protect it.

Understanding Seawater and the Ocean’s Role in Our Planet

When earning the Oceanography merit badge, you’ll learn about important properties of seawater and how they affect the ocean and the Earth. Physical oceanographers study these properties to understand the ocean’s behavior and its impact on the planet.

Key Properties of Seawater

• Salinity: This is the amount of salt dissolved in seawater. It is measured in parts per thousand (ppt). The salinity of ocean water averages about 35 ppt. Physical oceanographers measure salinity using special tools like a salinometer or by testing the water’s ability to conduct electricity.
• Temperature: This is how hot or cold the seawater is. Ocean temperatures can vary depending on location, depth, and time of year. Scientists use instruments like thermometers or CTDs (conductivity, temperature, and depth devices) to measure temperature at different depths.
• Density: This is how heavy seawater is for its size. The density of seawater depends on its salinity and temperature. Colder, saltier water is denser and tends to sink. Physical oceanographers measure density by calculating it from salinity and temperature readings.

These properties affect how water moves and supports life in the ocean.

Ocean Circulation and Currents

Ocean circulation refers to the movement of water through the world’s oceans. There are two main types of currents:

• Surface currents: These are caused by wind and move the top layer of water. The Gulf Stream is an example of a strong surface current.
• Deep currents: These are driven by differences in water density. Dense, cold water sinks and pushes warmer water upward in a process called thermohaline circulation.

These currents work together to form a global system called the ocean conveyor belt, which helps move heat, nutrients, and oxygen around the planet.

Oceans and Weather

The ocean plays a big role in weather and climate. It stores heat from the sun and releases it slowly, which helps regulate temperatures. Warm ocean water can fuel hurricanes and storms, while cold currents can cool nearby areas. The ocean also creates global wind patterns and helps bring rain to coastal regions.

By studying these systems as part of the Oceanography merit badge, Scouts can see how the ocean shapes life on Earth and learn why it is so important to care for it.

Understanding Ocean Waves and Their Effects

As you work on the Oceanography merit badge, you’ll learn about ocean waves and how they move through the water. Waves are caused by wind, earthquakes, or the gravitational pull of the moon and sun. They are made up of crests (the high points) and troughs (the low points). The distance between two crests is called the wavelength, and the height from the crest to the trough is the wave height.

Types of Waves and Their Differences

• Storm Surge: This is a rise in sea level caused by strong winds and low pressure during a storm, like a hurricane. It can flood coastal areas but is not a typical wave.
• Tsunami: These are large waves caused by underwater earthquakes, landslides, or volcanic eruptions. They can travel across oceans at high speeds and cause major damage when they reach land.
• Tidal Wave: This term is often misused to describe tsunamis, but it actually refers to the movement of water caused by tides, which are created by the gravitational pull of the moon and sun.
• Tidal Bore: A tidal bore happens when a high tide moves up a river or narrow bay against the current, forming a wall of water.

Understanding these types of waves is important for safety and for appreciating how the ocean works.

Sea, Swell, and Surf

• Sea: This refers to the choppy, short waves created by local winds. These waves are often irregular.
• Swell: These are smooth, long waves that travel far from where they were created. They are more uniform than sea waves.
• Surf: This is what happens when waves reach the shore. The waves break and roll onto the beach, creating the surf zone.

How Breakers Are Formed

A breaker is a wave that collapses as it reaches shallow water near the shore. When the bottom of the wave slows down due to friction with the seafloor, the top of the wave moves faster, causing it to curl and crash. Breakers are what you see when waves “break” at the beach, creating white foam.

The Oceanography merit badge helps Scouts understand these natural forces and how they shape the world’s coastlines and marine environments. This knowledge can also help Scouts stay safe when they visit the ocean.

Exploring the Ocean’s Underwater Topography

When earning the Oceanography merit badge, Scouts learn about the underwater features of the ocean floor. These features include the continental shelf, continental slope, and abyssal plain. Each plays an important role in the structure of the ocean and supports marine life.

Key Features of the Ocean Floor

• Continental Shelf: This is the shallow, gently sloping area of the ocean floor near the coast. It is rich in marine life because sunlight reaches the bottom, allowing plants to grow. Most fishing takes place here.
• Continental Slope: This is the steep drop-off that begins at the edge of the continental shelf. It leads down to deeper parts of the ocean. The slope marks the boundary between the continents and the deep ocean floor.
• Abyssal Plain: This is the flat, deep part of the ocean floor. It is covered with mud, sand, and the remains of tiny organisms. The abyssal plain is one of the most remote and least explored areas on Earth.

Understanding these features helps Scouts see how the ocean floor varies and why different parts of the ocean have different ecosystems.

Below is a simple cross-section diagram of these features:

Coastline        Ocean Surface  
    |__________                <- Continental Shelf  
               \               <- Continental Slope  
                \___________   <- Abyssal Plain  

By studying these underwater features as part of the Oceanography merit badge, Scouts gain a better understanding of how the ocean supports life and shapes our planet.

The Chemistry of Seawater

As you work on the Oceanography merit badge, you’ll learn about the salts, gases, and nutrients in seawater. These chemical components support marine life and affect how the ocean works. Understanding seawater chemistry helps scientists study marine ecosystems and protect the ocean.

Main Salts, Gases, and Nutrients

• Salts:
  • The main salt in seawater is sodium chloride, which is table salt.
  • Other salts include magnesium, calcium, potassium, and sulfate.
  • These salts make seawater salty and help marine organisms build shells and skeletons.
• Gases:
  • Oxygen: Vital for marine animals to breathe.
  • Carbon dioxide: Used by plants for photosynthesis.
  • Nitrogen: Important for the growth of plants and algae.
• Nutrients:
  • Nitrates and phosphates: Help plants grow.
  • Silicates: Used by tiny organisms called diatoms to build their shells.

Important Properties of Water

• Density: Water is denser when it is colder or saltier. This affects how ocean currents move.
• High Heat Capacity: Water can hold a lot of heat, which helps regulate the Earth’s temperature.
• Universal Solvent: Water dissolves many substances, including salts and gases. This makes seawater a mix of various chemicals.

How Plants and Animals Affect Seawater

• Plants like algae and phytoplankton release oxygen into the water during photosynthesis.
• Animals use oxygen and release carbon dioxide when they breathe.
• When marine organisms die, their remains sink and release nutrients, which support new life in the ocean.

Evaporation and Precipitation

• Evaporation: When water evaporates from the ocean, it leaves the salts behind. This makes the water saltier. Areas like the tropics, where it is hot and dry, have higher salinity.
• Precipitation: Rain and rivers add fresh water to the ocean, which reduces salinity. This happens in places with a lot of rain or near melting ice.

The Oceanography merit badge teaches Scouts how these processes work together to maintain the delicate balance of the ocean. This knowledge helps Scouts understand why the ocean is so important to life on Earth.

Life in the Ocean and the Role of Seawater

As you explore the Oceanography merit badge, you’ll learn that seawater has unique properties that make it an ideal home for marine life. It provides dissolved oxygen for animals, nutrients for plants, and stable temperatures that help organisms survive. These properties create the foundation for life in the ocean.

Biologically Important Properties of Seawater

• Dissolved Oxygen: Marine animals need oxygen to breathe. Waves and currents help mix oxygen into seawater.
• Nutrients: Elements like nitrogen, phosphorus, and iron in seawater support plant growth, especially phytoplankton.
• Light Penetration: Sunlight can reach the upper layers of the ocean, allowing plants and algae to perform photosynthesis.
• Temperature Stability: Water changes temperature slowly, helping to keep ocean ecosystems stable.

Ocean Life Groups: Benthos, Nekton, and Plankton

• Benthos:
  • These are organisms that live on or near the ocean floor.
  • Examples: Crabs, clams, starfish, and seaweed.
  • Importance: Many benthic organisms are scavengers, helping to clean up the ocean floor.
• Nekton:
  • These are animals that swim freely in the water.
  • Examples: Fish, dolphins, squid, and sharks.
  • Importance: Nekton are key predators and prey in the food chain.
• Plankton:
  • These are tiny organisms that float or drift in the water.
  • Examples: Phytoplankton (plants like algae) and zooplankton (animals like tiny shrimp).
  • Importance: Plankton form the base of the ocean food chain.

The Importance of Phytoplankton

Phytoplankton are microscopic plants that live near the ocean’s surface. They use sunlight to produce energy through photosynthesis. This process releases oxygen, making phytoplankton a major source of the oxygen we breathe.

Phytoplankton are also the foundation of the oceanic food chain. Small animals like zooplankton eat them, and larger animals like fish and whales eat the zooplankton. Without phytoplankton, the entire marine food web would collapse.

Learning about the properties of seawater and the roles of benthos, nekton, and plankton in the ecosystem is a key part of earning the Oceanography merit badge. This knowledge helps Scouts understand how life in the ocean is interconnected.

Collecting and Studying Plankton

As part of the Oceanography merit badge, you may collect plankton using a homemade plankton net. This activity helps you see some of the tiny organisms that form the foundation of the ocean’s food chain. It’s a hands-on way to learn how scientists study life in the ocean.

Making and Using a Plankton Net

A plankton net is a cone-shaped net designed to catch small organisms floating in the water. To make one, you’ll need fine mesh fabric (like nylon), a hoop for the opening (a coat hanger works), and a container to collect the sample. Attach the fabric to the hoop, then secure a small bottle or jar to the narrow end to catch the plankton.

Tow the net in the water for about 20 minutes. You can do this by:

• Pulling it from a dock.
• Wading with it in a stream or near the shore.
• Holding it in a strong current.
• Towing it from a rowboat.

Once you have your sample, transfer it carefully to a clear container for observation.

Examining and Identifying Plankton

To study your sample, use a microscope or a magnifying glass. You’ll likely find two main types of plankton:

• Phytoplankton: These are tiny plant-like organisms that perform photosynthesis. Common examples include:
  • Diatoms: Single-celled algae with glass-like walls.
  • Dinoflagellates: Microscopic plants that can glow in the dark.
• Zooplankton: These are tiny animals or animal-like organisms. Common examples include:
  • Copepods: Small crustaceans that swim with jerky movements.
  • Larvae: Baby fish, crabs, or other marine animals that start life as plankton.

Why Plankton Matter

Plankton are the foundation of the oceanic food chain. Phytoplankton produce oxygen and serve as food for zooplankton. Zooplankton, in turn, feed larger animals like fish and whales. By studying plankton as part of the Oceanography merit badge, you can see how even the smallest organisms are vital to life in the ocean.

This activity also teaches you how scientists gather and analyze samples to learn about ocean ecosystems. It’s a fun and educational way to explore marine life up close.

Modeling the Growth of a Volcanic Island and Coral Reefs

The Oceanography merit badge includes learning about how coral reefs form around volcanic islands. One way to understand this process is by creating models that show the stages of reef growth and the development of an atoll. You’ll also learn about the Darwinian theory of coral reef formation, which explains how this natural process occurs.

Making the Models

You can use materials like clay or plaster for the island and wood or small plastic pieces for the reef. Create three models to show the stages of reef growth:

• Fringing Reef: The first stage. Coral grows directly along the edges of a volcanic island. The reef hugs the shore, and there is little or no lagoon (shallow water between the reef and the island).
• Barrier Reef: Over time, the island begins to sink or erode, and the coral continues to grow upward. A lagoon forms between the island and the reef. The reef becomes a barrier around the island.
• Atoll: In the final stage, the volcanic island sinks completely below the surface. The coral reef remains, forming a ring-shaped atoll around a central lagoon.

These models show how reefs change over time as the land beneath them moves and sinks.

Darwinian Theory of Coral Reef Formation

Charles Darwin was the first to propose a scientific explanation for how atolls form. His theory states that coral reefs grow upward as volcanic islands slowly sink over millions of years. The coral keeps building toward the surface, staying in the shallow water where it can get sunlight.

The stages of reef formation—fringing reef, barrier reef, and atoll—happen because the coral grows while the island sinks. Darwin’s theory has been supported by modern studies of coral reefs and volcanic islands.

Importance of Coral Reefs

Coral reefs are important ecosystems that support a wide variety of marine life. They protect coastlines from waves and storms, provide food and shelter for fish, and are valuable to humans for fishing and tourism.

By making these models and studying coral reefs as part of the Oceanography merit badge, Scouts learn how natural processes shape the ocean environment and why coral reefs need to be protected.

Measuring Water Temperature, Turbidity, and Weather Conditions

The Oceanography merit badge includes activities to help you understand how water temperature and clarity are affected by weather and environmental conditions. Measuring water temperature at different depths, checking turbidity, and recording weather observations gives you insight into how the atmosphere and water interact.

How to Measure Water Temperature

To measure water temperature:

• Use a thermometer to record the temperature at the surface, midwater, and bottom. Tie the thermometer to a rope and lower it into the water to the desired depth.
• If you don’t know the depth, tie a rock to the rope and mark it with measurements (in feet or meters). Lower it until it touches the bottom and note the depth.
• Repeat this process four times daily for five days to observe changes.

Making and Using a Secchi Disk

A Secchi disk is a simple tool used to measure turbidity, or how clear the water is. To make one:

• Use a round disk (like a plastic or metal lid) about 8 inches wide. Paint it with alternating black and white quadrants.
• Attach it to a rope marked with depth measurements.
• Lower the disk into the water until it disappears. Measure the depth at which it vanishes. This is the turbidity level.

Observing Air and Water Conditions

Each time you take measurements, also record:

• Air temperature: Use a thermometer to measure the temperature above the water.
• Cloud cover: Note if the sky is clear, partly cloudy, or overcast.
• Water roughness: Observe if the water is calm, slightly wavy, or rough.

Graphing and Analyzing Your Data

After collecting your data, create graphs to compare:

• Water temperature at different depths: Plot time of day on the x-axis and temperature on the y-axis for surface, midwater, and bottom readings.
• Turbidity: Show how it changes over time.
• Air temperature vs. water temperature: Compare how air temperature affects water temperature.

Water temperature often changes with air temperature, especially at the surface. When the air is warmer, the surface temperature rises. However, deeper water remains more stable because sunlight and air do not directly heat it.

By completing these observations for the Oceanography merit badge, you’ll gain a deeper understanding of how water and air interact and how scientists study aquatic environments. This hands-on activity helps you see how weather, sunlight, and sediment affect bodies of water.

Modeling Sediment Movement Along the Coast

As part of the Oceanography merit badge, you’ll study how waves, tides, and currents move sand and sediment along the shore. Creating a model helps you understand coastal features and how they change over time due to natural forces like littoral currents and wave action.

Understanding Coastal Processes

• Littoral Currents: These are currents that run parallel to the shore, caused by waves hitting the beach at an angle. They move sand and sediment along the coast, a process called longshore drift.
• Tidal Movement: The rise and fall of the tide shift sediment between deeper water and the shore. High tides deposit sediment further up the beach, while low tides expose more of the shore.
• Wave Action: Waves carry sand toward the shore and remove it, shaping the coastline. Storms can speed up this process.

Key Coastal Features to Include

Your model should show these formations:

• High and Low Waterlines: The highest and lowest points that water reaches during tides.
• Low-Tide Terrace: A flat area exposed at low tide, located below the berm.
• Berm: A ridge of sand or pebbles above the high tide line, built up by waves.
• Coastal Cliffs: Steep rocky areas formed by wave erosion.
• Offshore Bars: Ridges of sand built up by waves, located in shallow water beyond the low tide line.

Offshore bars can change over time. Strong waves pile sand to form the bars, but storms or shifting currents can break them down.

How to Make the Model

1. Use materials like sand, clay, and rocks to create a cross-section of a shoreline in a box or tray.
2. Label the key features: high and low waterlines, low-tide terrace, berm, and coastal cliffs.
3. Show the effects of littoral currents and wave action by dragging a stick or ruler across the sand at an angle to simulate sediment movement.
4. Build a small offshore bar and demonstrate how it might change by pushing waves (water) against it with your hand.

Studying sediment movement helps scientists understand how coastlines change and how to protect them. Beaches erode naturally over time, but human activities like building seawalls or dredging can speed up these changes. By creating this model as part of the Oceanography merit badge, you’ll learn how the ocean shapes the land and why it’s important to protect coastal environments.

Building a Wave Generator and Observing Coastal Effects

The Oceanography merit badge includes hands-on activities to learn about how waves move and how structures like groins, jetties, and breakwaters change wave patterns. A simple wave generator lets you see how waves reflect, refract, and interact with obstacles.

Making a Wave Generator

You can make a wave generator using a shallow tray or clear aquarium, water, and a paddle:

1. Fill the tray with water to a depth of a few inches.
2. Use a flat object like a ruler or piece of wood to gently move the water back and forth to create waves.
3. Practice creating consistent waves to observe their behavior.

Reflection and Refraction

• Reflection: When a wave hits a solid surface, like a wall, it bounces back. To see this, place a small flat object like a board at one end of the tray and send waves toward it. Watch how they bounce back in the opposite direction.
• Refraction: Waves bend when they pass from shallow to deeper water or around an obstacle. Place a sloped object like a piece of plastic in the tray to mimic a seafloor that gradually becomes deeper. Watch how the waves bend as they move across the slope.

Effects of Groins, Jetties, and Breakwaters

Place small objects like blocks or rocks in the tray to represent coastal structures:

• Groins: These are barriers built perpendicular to the shore to prevent sand from washing away. In your model, place a groin and observe how it blocks waves and changes their direction.
• Jetties: Similar to groins, jetties are placed at the mouths of rivers or harbors. They protect the channel from waves and sand. Add two blocks to simulate a jetty and watch how waves are redirected.
• Breakwaters: These are structures built parallel to the shore to calm the waves before they reach the beach. Place a breakwater in the tray and notice how the water behind it becomes calmer.

Waves are powerful forces that shape coastlines. Structures like groins, jetties, and breakwaters are designed to protect beaches and harbors, but they can also disrupt natural sand movement, causing erosion in some areas while building up sand in others.

By using a wave generator and studying these effects for the Oceanography merit badge, you’ll better understand how waves behave and how human structures interact with natural forces. This knowledge helps Scouts appreciate the balance needed to manage and protect coastal environments.

Using Satellite Images to Study Oceanography

As part of the Oceanography merit badge, tracking satellite images is a great way to learn about changes in the ocean and coastal environments over time. Satellite images show large-scale features like ocean currents, temperature changes, and weather patterns. By monitoring these images for three weeks, you can observe how the ocean and atmosphere interact.

To track satellite images, choose a website that provides up-to-date satellite data. Some good options include:

• NOAA’s CoastWatch: Offers ocean and coastal satellite imagery.
• NASA’s Earth Observing System Data: Provides global satellite images of the Earth.
• Earth.Nullschool.net: Displays live ocean currents and wind patterns.
• Google Earth: Allows you to explore historical and current satellite images.

Look for a specific feature to monitor, like ocean surface temperatures, algae blooms, or weather systems, and record your observations regularly.

What to Observe

• Sea Surface Temperature: Satellites show heat levels at the ocean’s surface. Changes can indicate currents, like the Gulf Stream, or seasonal differences.
• Cloud Cover and Weather: Watch how storms form over the ocean and move toward land.
• Chlorophyll Levels: High chlorophyll often indicates phytoplankton blooms, which are important for the food chain but can also signal pollution.
• Coastal Erosion: Look at changes in shorelines to see the effects of waves, tides, and human activity.

Analyzing the Images

Create a journal to record what you see. Take notes on patterns or changes in the area you are monitoring. You can also take screenshots to compare images week by week.

After three weeks, summarize your findings:

• Did you notice any changes in temperature, currents, or other features?
• How did weather patterns or storms affect the area?
• Were there any signs of human impact, like runoff or sediment in coastal waters?

Satellites provide a bird’s-eye view of the ocean, showing large-scale processes that are impossible to see from the ground. By analyzing these images for the Oceanography merit badge, Scouts can learn how the ocean changes over time and how it affects the planet. This activity also introduces Scouts to tools used by oceanographers to study and protect the Earth’s oceans.

Exploring Oceanography Through Books

For the Oceanography merit badge, reading a book about oceanography is a great way to deepen your knowledge about the ocean. A good book can explain how the ocean works, its role in Earth’s systems, and the challenges it faces. Below are some recommended books.

• “The Ocean Book” by Frank Sherwin: A beginner-friendly guide to ocean science and marine life.
• “Exploring the Deep: The Titanic Expeditions” by James Cameron: A mix of science and adventure.
• “Tracking Trash: Flotsam, Jetsam, and the Science of Ocean Motion” by Loree Griffin Burns: A look at how ocean currents move debris and why it matters.

Completing the Visit Requirement for the Oceanography Merit Badge

To fulfill this requirement, visit an oceanographic research ship, marine laboratory, oceanographic institute, or marine aquarium. Choose a location where you can learn about marine science, ocean ecosystems, or the technology used to study the ocean. Plan your visit in advance and find out if there are tours, exhibits, or staff available to answer questions.

During your visit, focus on how scientists study the ocean. Look for exhibits or demonstrations about marine life, water quality, and ocean systems. Pay attention to how they monitor important properties like temperature, salinity, and turbidity. If visiting a marine aquarium, observe the variety of species and how their habitats are recreated.

Take notes about what you see and learn. Ask questions about challenges the ocean faces, like pollution, climate change, or overfishing. These observations will help you prepare your report and understand how your visit connects to the concepts covered in the Oceanography merit badge.

After your visit, reflect on how the experience deepened your understanding of oceanography and the importance of protecting the ocean.

Marine scientists use a variety of methods to explore the water, the ocean floor, and the life within it. Each technique provides valuable data to help us understand the ocean’s role on Earth.

Methods for Studying the Ocean

• Satellites: Satellites orbit the Earth and collect data about the ocean’s surface. They measure sea surface temperature, currents, and even the height of waves. This helps scientists study large-scale processes like ocean circulation and weather patterns.
• Research Ships: Specially equipped ships allow scientists to conduct experiments and collect samples at sea. They use tools like nets to capture marine life, water samplers to study chemical properties, and sonar to map the seafloor.
• Submersibles: These are underwater vehicles that can dive deep into the ocean. Submersibles help scientists explore places humans can’t easily go, such as deep-sea trenches. They are used to study unique environments like hydrothermal vents.
• Remotely Operated Vehicles (ROVs): ROVs are robotic submarines controlled from the surface. They are equipped with cameras and tools to collect samples. ROVs are commonly used to explore shipwrecks, coral reefs, and deep-sea habitats.
• Sonar Technology: Sonar uses sound waves to map the ocean floor. Scientists send out sound signals and measure how long it takes for the echoes to return. This method helps them create detailed maps of underwater mountains, valleys, and trenches.
• SCUBA Diving: Scientists use SCUBA (Self-Contained Underwater Breathing Apparatus) to observe marine life and collect samples in shallow water. This hands-on method is especially useful for studying coral reefs and kelp forests.
• Plankton Nets and Water Samplers: To study small organisms and water properties, scientists use plankton nets to collect microscopic plants and animals and water samplers to examine temperature, salinity, and nutrient levels.
• Ocean Observatories: These are fixed stations on the seafloor or in the water that collect long-term data. Sensors on these observatories measure currents, temperature, and chemical changes in the ocean over time.

Each of these methods helps marine scientists answer important questions about the ocean, like how it supports life, how it changes over time, and how humans are impacting it. By learning about these tools and techniques, Scouts working on the Oceanography merit badge gain insight into how science is used to explore and protect the ocean.
