Have you ever seen these Titanic exploration videos? How breathtaking they are! When watching this passenger liner underwater, you can easily imagine how stunning it looked before being submerged by ocean waters. Would we have a chance to see it without modern technologies? Probably no. 

While you might not read lots of marine science news, the field has gone far. The real miracles take place here with the help of tech advancements. 

Let’s take a look at some of the greatest marine science technologies! 

Frontiers in Marine Science

Frontiers in Marine Science

As we’ve learned, 97% of the world’s water is the ocean, but a surprising fact is that about 80% of it has never been explored or mapped. What’s wrong? 

For many centuries, humanity didn’t have the proper means to explore the ocean. But these “dark” ages have passed. Today’s technologies allow us to know more and more about marine life. Step by step, we’re getting closer to discovering the mysterious depth of waters. 

Know more about marine life

Here is the list of go-to techs:

  • GIS Mapping

GIS or geographic information systems help marine scientists to create a virtual ocean map within a computer. With the GIS system’s help, marine scientists can view and process spatial information on a digital platform. Thus, geographical information is captured, stored, and displayed easily. Just one click and images of underwater flora and fauna appear on your screen.

  • HFR (High-Frequency Radars)

Among marine biology current events, the creation of HFR is an important step in the world of science. This technology allows measuring the speed and direction of ocean currents near the coast at once. It embraces the surface up to 200 km. A signal is sent to the sea by a particular transmitter, and then the seawater surface returns this signal back but with useful data. 

Why is it important? The answer is simple: HFR helps detect objects floating on the sea surface, critical for searching and rescuing missions and exploring and studying environmental conditions.

  • Seaglider

One of the frontiers in marine science is the seaglider. What’s that? Let’s find out!

Seaglider is an underwater vehicle that measures oceanographic parameters. There are electrically driven propellers that marine scientists can use for exploring aquatic life. However, they are still overwhelmed by the glider, which produces only a small effect on flotage to move forward.

This marine science technology can cover thousands of miles and go to depths up to 1000 meters down. Moving through the water in a saw-tooth manner, the seaglider collects oceanographic data essential for research, such as water temperature and salinity, with sensors’ help.

Animal Telemetry

Animal telemetry takes an important place among advances in marine biology. Briefly, it’s a tagging system. Involving animals to carry electronic tags, animal telemetry gives us such an amazing opportunity to observe how these animals interact with the ocean and each other.

With this knowledge, exploring and understanding the underwater life and investigating the problem of climate change and environmental pollution becomes easier. Since 1990, animal telemetry has enabled us to collect information from the most unreachable areas in the ocean, where most of the traditional methods simply don’t work.

Drifters

Using this marine science technology, global ocean current, temperature, wind, ocean color, pressure, salinity, and effects on the environment can be easily studied. 

Drifters are usually equipped with GPS and a transmitter in order to track their location and receive the data in real-time. When marine scientists put this device on the water surface, it starts sending data to the satellite and later receiving stations. Once the data are in the hands of scientists, it can be processed.

Underwater Hydrophone

If you think there is no noise underwater, you’re so wrong. A myriad of sounds can be heard underwater, but acoustic transmitting in the water environment is much lower. Therefore, one of the most go-to frontiers in marine science is an underwater hydrophone. 

This is a small device (about 35 cm) that detects underwater noise. Producing a small electrical current and being exposed to underwater sounds, hydrophone amplifies and records these signals.

SONAR

With SONAR or Sound Navigation and Ranging, marine scientists find and identify objects in the water. Using sound waves, which happen to be more effective than electromagnetic waves, it’s possible to detect any object (if the sound is reflected to the receiver) and measure water depth at almost any location. Besides, SONAR can easily detect signals produced by ships, submarines, or marine animals. Thus, this technology is highly valuable in naval operations.
