What Do Marine Biologists Do?

Here are top 25 things that marine biologists on their day-to-day lives.

1. Studying Diverse Sea Creatures

Marine biologists dive into the ocean to learn about lots of sea life. They look at big animals like whales and small ones like plankton. But there is so much more.

Some marine biologists are keenly interested in special fish or coral types. Others like to find out about weird creatures that live deep down on the ocean floor. For example, George Brown Goode made a name for himself by collecting different fish species.

This work helps us understand how each creature fits into the big picture of life underwater.

2. Exploring the World of Plankton

Marine biologists dive deep to study the tiny world of plankton. These small water-dwelling creatures may seem simple, but they hold big secrets about our oceans. You can see many of them in places like the Barents Sea, where they come together in large groups called blooms.

Studying these blooms tells us more about our marine ecosystems’ health and movement. This shows that even the smallest life forms have a big role to play in our world under the waves!

3. Observing Majestic Whales

Not many sights match a whale breaching the ocean’s surface. Seeing this is part of a marine biologist’s work. Whales are big sea animals, reaching over 100 feet in size. Marine biologists spend time studying these large beings.

They watch how whales live and interact with each other. Some whales stay together in groups for long periods, showing social behaviors. These scientists want to understand why they do this.

What sound does a whale make? They sing complex songs that wow people who hear them! It is another area marine biologists study about whales.

Then there are questions about how these giant creatures see us humans. We still don’t know if whales see humans as only black and white or in color, too!

4. Choosing Specialized Fields

Marine biologists dive into detailed areas of marine life. They pick a specialized field.

They study one part of the ocean world.
Some become experts in phycology, the study of seaweed and algae.
Others might choose ichthyology and learn all about fish.
The strange world of squids and octopuses pulls in some. They become experts in invertebrate zoology.
Studying whales, Seals, and dolphins is called marine mammalogy.
Fishery biology is another choice for them. It’s good if you want to help manage our fish stocks.
There’s marine ecology for those who love to see how everything fits together.
Special fields give these scientists powerful tools to help sea life.
Each field allows them to explore how specific plants or animals live.
These experts find new facts about sea creatures every day.

5. Diverse Methods of Ocean Exploration

They use high-frequency radars. This helps them map the ocean floor.
Sea gliders glide through the water. They collect data about the ocean.
Animal telemetry tracks marine animals. This tells us where the animals go and why.
Marine biologists also deploy buoy systems at sea, collecting data about tides, currents, and weather changes.
They even use submersibles. These are special vehicles that can dive very deep into the ocean.
Some marine biologists like to get up close; they scuba dive to observe or collect marine samples.
Others use drones or satellites for large-scale monitoring and mapping of marine environments.

6. Deciphering Celestial Effects on Tides

Marine biologists find out why tides move. They look at the moon and stars to see how they pull on the seas. The pull of gravity from these bodies makes sea levels rise and fall. This is called a tide.

Even volcanoes can be tied to tides, scientists say! Marine biologists use what they learn from natural patterns to help them study sea life better.

7. Diving into Water Chemistry

As a marine biologist, you dive deep into water chemistry. You study the mix of salt and other things in the ocean. This helps you know how sea plants and animals survive. Changes in water chemistry can hurt or help marine life forms.

With this knowledge, You devise ways to aid them when needed. Scuba diving lets you take samples from different ocean depths for testing. All of these tasks make your work day fun! Each dive brings new findings about the secret life under the waves.

8. Understanding Marine Interactions

Marine biologists dive deep to figure out how sea life gets along. They examine all connections between water plants, fish, and marine animals. This part of marine biology is called biological oceanography.

Aristotle once studied the same things! He helped shape our view of interacting marine species. Marine biologists today still gather samples from the sea for study in labs, just like he did in ancient times.

This research helps them learn all about the underwater world and helps us understand it, too!

9. Unearthing Ocean Floor Geology

Marine biologists dig deep into the ocean’s bedrock. They use special tools to uncover mysteries beneath the surface. This includes looking at sea bed rocks, soil, and sand layers.

It needs a lot of careful work! Studying what’s under the water tells us about times past. Unseen fossils or stones may tell tales from thousands of years ago! Many marine scientists give all their time to this study area.

More research helps us learn more about our planet’s history. Marine biologists aim to better understand how we can best protect our oceans now and in the future.
