The Deep Sea. It is a vast body of water that has been described as a sea of secrets, which is one of the reasons scientists have devoted so much attention to investigating its deep fauna and microfossils. Microfossils are small bits of matter once alive; they record information about the ancient past and give insight into what once grew on our planet and how it has evolved. Examples of microfossils include the shells of tiny marine snails and algae, pollen grains, and even small bones and teeth from larger animals.

To find these microfossils, scientists use a wet mount microscope to look at the surface of the sediment. This microscope looks like a small fish tank with a fish in it. In this fish, a fixed lens focuses on just one area to too many areas simply by sliding from one extreme to another. The camera inside the wet mount microscope takes a picture of what is under the lens every few minutes and records information about what it sees in 30-second intervals so it can show scientists moving things in and out of focus. Fossils, scientists use a deep-sea lander. It is a small vessel that is lowered into the water by an extensive research ship; it then sinks to the deepest depths where bottom samples can be collected without the risk of scuba diving at such remote locations. When these samples are collected, they are brought back to laboratories on land for detailed analysis.

The information collected at the deep sea is essential for scientists with little or no knowledge of biology or geography. It is hoped that this research will help them understand the existence of plants and animals in an environment that has hardly ever been explored. The most satisfying part of doing initial research at the deep sea is when you see your work formulating into something helpful to others who will use your findings in many different ways. The characteristics of the marine environment, which is a place between the continents, present a constant struggle for scientists. The first thing you have to remember is that the oceans do not only cover over 70% of our planet’s surface, but they also deposit 89% of Earth’s sediment. Due to this extreme heat and pressure, life in the deep sea is not as easy as it might seem; it can be hard work collecting data for scientists to use in their experiments, like taking pictures.

A microscope camera is a tricky tool to use on a wet mount microscope to investigate marine organisms. It is necessary to adjust the focusing knob with different levels of force that one can spread from very light to very hard. However, a microscope camera is designed for a simple task: taking a picture every few seconds and recording information about what it sees in 30-second intervals. Each time the lens is adjusted to focus closer, it needs to be changed back to its original position for accuracy. It is vital if you need clarity in your image; if you forget to make adjustments before taking your picture, the idea will blurry and not give information about what it sees. Because of this problem, scientists must learn how to deal with these intricacies during their initial research on the deep sea.

The most important thing to consider when setting up a microscope camera on a wet mount is understanding your subject. The process of collecting samples for this type of research is slow and tedious. It is essential to take pictures at the exact location repeatedly so that you can watch things grow or move around. This way, scientists can learn about the growth cycle of the marine animal they are studying. To better understand what you are seeing, it is beneficial to understand biology and geography.

Types of Microfossils

There are many different types of microfossils. Some of the most common are the following.


The kinds of animals with shells are different depending on the period you are studying. For instance, there was a period when giant corals grew in the deep sea and were incredibly abundant. They fell to the seafloor when they died, forming large deposits that became limestone rock. These formations are known as reef structures, and they can be found in parts of the tropics today. The system is similar to the reef structures located off the coast of Florida; these are living corals that protect other small marine creatures who live in the ocean near them.


Due to the fossils, they are most commonly known as planktonic foraminifera. Algae are tiny, single-celled organisms that float around in the water and help give nutrients and oxygen to other living near it. Sometimes, algae grow into larger colonies that themselves become a significant part of the ecosystem. When they die, their bodies break down into a sedimentary rock that forms a limestone called a coral reef structure. The limestone deposits’ size depends on the number of algae that died and settled at the bottom of an ocean.


An example of this is gymnosperms, which are plants without seeds or fruits. Male plants release pollen, and it helps them disperse their offspring to other plants to survive. The pollen can be collected and stored for future use.


Although radioactive, this microfossil can be collected and stored for use by scientists who wish to study the effects of radiation and how it affects the deep-sea ecosystem. Radiolaria are members of a group of invertebrate animals called Radiata. Radiata fills many different roles, including defensive, storage, filtering, and locomotion.


This tiny filtering organism is a cephalopod, a group of animals including octopi, squid, and cuttlefish. In captivity, it can grow to the size of a softball. This type of animal has been found in deep waters, from the cold waters around Antarctica to the deepest parts of the Pacific Ocean.


It is a small, bilaterally symmetrical animal with a complex, calcified skeleton and five body sections (the head and two arms, and two feet). It is often found in deep-sea abyssal plains of the Atlantic Ocean. They can be collected and stored for future use by scientists studying marine ecosystems.

There are many other examples of microfossils such as ostracods, chitinozoans, macerated rock types found on beaches or mid-ocean ridges.

Microscopic specimens are a valuable tool for scientists studying the deep sea. It is essential to understand how to set up a microscope camera on a wet mount and how to understand different types of fossils and what they mean! It is also important that scientists know that their samples are valuable and may not necessarily be disposable.
