Deep Sea More Accessible Now Thanks to New Low Cost Device

deep sea

MIT researchers have developed a prototype of a low-cost device to explore the deep sea that they have named the Maca Niue. They have also sent advanced prototypes to scientists in 11 countries, who have adapted the device to fit their needs and made recommendations for further development. Currently, seven countries are testing advanced prototypes of the Maca Niue, including Portugal and Montserrat, as well as Hawaii and Louisiana in the United States.

OpenCTD sensor

OpenCTD was developed by Andrew Thaler, a visiting scientist at the Virginia Institute of Marine Science, in conjunction with Kersey Sturdivant. While developing this device, Thaler and his team encountered difficulties with conductivity measurements. To overcome this problem, the team sourced a conductivity circuit from Atlas Scientific. The circuit only costs $50, and makes the project much easier to use.

The OpenCTD project aims to make CTD sensors more affordable for citizen scientists. The goal is to create a sensor that is smaller than a commercial CTD. The OpenCTD project’s development has already come a long way, and now it is in a state where a normal person can build one. While this sensor isn’t a replacement for commercial devices, it could be an alternative for citizen scientists to collect data about the deep sea for free.

CTD sensors measure a variety of parameters, including temperature, conductivity, and depth. CTD measurements allow oceanographers to map the interior of the ocean by comparing the physical properties of the water column at different depths. They also help them understand the structure of the water column, as well as detect anomalies. These measurements allow scientists to make better decisions about exploration.

Maca Niue data collector

The Maca Niue data collector is a tiny, battery-powered device that can take measurements up to 1,500 meters deep. It has sensors that will allow scientists to determine the temperature, salinity, and depth of a specific area, allowing them to monitor the deep ocean in unprecedented detail. The device can also help scientists discover new species and new habitats. Additionally, it can help communities gather baseline data and monitor the health of a particular habitat.

Until now, deep sea exploration has been reserved for the wealthy. It has been accessed by fossil fuel companies and select scientists from wealthy countries. However, the vast majority of the deep ocean remains unexplored. The natural wonders of the deep sea remain poorly understood and vulnerable to exploitation. Many scientists and conservationists have called for the democratization of deep sea research. Now, a low-cost data collector may make deep sea exploration accessible to everyone.

Humanoid underwater robots

A new generation of humanoid underwater robots could make the deep sea accessible to everyone. Unlike traditional human divers, robots can remain underwater for a long time and collect samples. They can also sense objects hundreds of feet below and adjust their grip strength accordingly. They can also explore dangerous and remote parts of the ocean.

The Aquanaut is an uncrewed robotic submarine that is designed to perform a variety of jobs. Offshore oil and gas production requires a vast amount of underwater equipment and support structures. Meanwhile, offshore wind power is one of the fastest growing industries. By 2030, there could be 25,000 offshore wind turbines in operation. Each of these will need regular maintenance and servicing.

The OceanOneK robot was developed by computer scientists at Stanford University. It is capable of diving to 1,000 meters. The robot is fitted with sensors and algorithms to navigate and identify delicate objects. Its body contains special foam and glass micro-spheres to enhance buoyancy.

This robot is designed to reach dangerous environments and archeologically significant wrecks. It can also help humans distance themselves from these dangerous environments. With this, the robot can assist in disaster recovery and disaster prevention.

Imaging technology

Imaging technology may be able to make the deep sea accessible to everyone. Researchers at the Woods Hole Oceanographic Institution (WHOI) are developing advanced medical imaging tools to examine the internal organs of mollusks – a diverse group of invertebrate sea creatures. These techniques, such as computed tomography (CT) scans, provide a non-destructive way to look inside an organism. Previously, scientists had to use invasive methods to view these organs.

Underwater hyperspectral imaging (UHI) is a technique that uses a high-resolution imaging system to map ocean areas. It is an extension of hyperspectral imaging technology used in air conditions. This method allows users to see details of the seabed at high resolution, without the need for expensive or large telescopes. It is also useful for examining changes in food sources, monitoring seabed composition, and assessing coastal ecosystems. While further research is needed to fully exploit the potential of this imaging technology, it can already be used as an automated classification tool.

The first UHI system was invented by Johnsen, a Norwegian researcher. This device was mounted on a cart that could be towed to the seafloor. Underwater divers would position the UHI on a track and observe objects in shallow water using halogen lamps. Subsequently, researchers at NTNU and Ecotone AS have developed a series of underwater hyperspectral imagers, a type of camera that is capable of reaching wavelengths of 2.2 nm between 380 and 750 nm. The grating in the system is used to disperse the light and provide a detailed image.

Power systems

Power systems could be an essential tool for exploration of the deep sea. They can be used to power remote sea sensors, autonomous underwater vehicles and other devices that need to operate at extreme depths. The technology could also facilitate long-range oil prospecting. In addition, it can prospect ocean-floor monitoring systems and marine-research devices.

If you are interested in a career in power systems engineering, you should know that it is challenging but also highly rewarding. The job can be financially rewarding, as well. According to PayScale, a position in this field can pay between $60,722 and $103,832 per year.
