The biggest threat to the future of mankind and other living organisms is the climate change. The ocean is the great climate regulator on the planet, therefore, is essential to monitor the ocean to predict where and when the changes will occur as well as their intensity, in order to minimize the damage. The South Atlantic and Tropical are very little monitored and many ocean phenomena that happens in these regions affect the climate worldwide.

 

Submarine Research Station Powered by Oceanic Currents

The LabTecMar is developing the world’s first Submarine Research Station (SRS) that will use the energy of the tides or oceanic currents to generate their own electricity, operating during years without maintenance. The data and images stored in these stations may be collected by autonomous vehicles, acoustic systems, laser or satellite through an antenna-winch system. Our goal is to install various of  these stations in the South and Tropical Atlantic, creating a long-term monitoring system. The energy will be generated by a VAOCT (Vertical Axis Ocean Current Turbine).

 

Columnar Buoy System

 

A new type of monitoring buoy is also being developed. It is a columnar buoy that can monitor the entire water column. This buoy can be used, for example, for monitoring the artificial reefs.

 

South Atlantic Underwater Vehicles Explorers — SAUVE

 

 

Several vehicles, with different approaches, should be created within the SAUVE project. The first vehicle of this series will be a hybrid model that move autonomously (AUV) or remotely controlled (ROV). In autonomous mode, it will be guided by isobaths (which are lines of equal depth parallel to the coast) with the aid of sonar and electronic compass.

 

OOCEANAT – Oceanic Observatory and Interaction with the Atmosphere

The idea of ​​ocean observatories (OOI) is to create extensive monitoring networks on the seabed, allowing to monitor in real time  chemical, physical, geological and biological phenomena that occur in these environments. Led by the United States, which considers it the greatest advance in marine research over the past 50 years, is also being adopted by other countries.

 

The LabTecMar has a project to create an ocean observatory in Brazil, based on an innovative system called MBNAS (Multibuoys Network Array System) or simply Multibuoys. This system is based on a long distance wireless communication network over the sea. This technology will use various buoys lined up of the coast towards offshore  and others scattered in a bay. All buoys will have measuring instruments and cameras controlled by a computer and will communicate with each other and with a shore station control, forming a monitoring network with high speed in real-time.

 

One of the buoys may be 100 m in length, forming a very stable structure, important for certain types of research. The energy to power the equipments will be obtained by Vertical Axis Wind Turbines (VAWT), which have low maintenance. The batteries are housed in the bottom of the buoys where the temperature is low, allowing them to last 10 years or more.

AUV Docking Station OCCUR Powered

 

 

This docking station, to recharge and communication, is powered by the oceanic currents (OCCUR). A OCT (Oceanic Currents Turbine) will generate electric energy to recharge the batteries of autonomous vehicles  (AUV) through an electromagnetic charger system. This innovation will allow a AUV to explore a particular place, for example, in deep ocean for long-term.
