Schmidt Ocean Institute Collaborates with Latitude Engineering

We know more about the universe than we do about the oceans. As such, it is no surprise that researchers are looking for new ways to understand the ocean. Of particular interest is the sea surface microlayer (SML) which is identified as the top 1 millimeter of the ocean surface.  

Removing the mystery

The SML is where all gas exchange between the atmosphere and the ocean occurs. However, the processes that control carbon dioxide transport and transformation in oceans remain largely unknown. To better understand the overall health of the ocean, scientists need to model the transfer of gases between the atmosphere and the ocean. Such a model would allow for the creation of regional and global budgets of carbon, nutrients and pollutants. When waves break on the surface of the ocean, mixing occurs. This allows gas from the atmosphere to enter the water and water from the ocean to enter the atmosphere. Scientists know a lot about mixing at wind speeds between 6 and 30 knots. However, there is still much to discover at lower speeds.  

Flat water working conditions

The SML is an oily film which is more prevalent when the water is calm. In flat water conditions it is fair to suspect that the micro-layer suppresses waves and decreases mixing. This is why the science team on the R/V Falkor journeyed to the flat water conditions found off the coast of Darwin, Australia. One reason so little is known about the SML is that the mere presence of the boat disturbs the microlayer, making it nearly impossible to get accurate, untainted data. Studying this microlayer entails a few challenges. Research vessels must travel far out into the ocean to find flat water conditions. And, once there, the research equipment must operate away from the boat to get undisturbed Microlayer data. So, how does a researcher collect ample undisturbed SML data and not blow the budget? Enter Latitude and the HQ-60's real-world-tested VTOL capabilities.  

HQ-60 hybrid VTOL

Based on previous work with NOAA and the R/V Oscar Elton Sette off the coast of Hawaii, the Latitude team was up to the task. The unique design of the HQ-60 enables vertical take off and landing. Thus, the small footprint of the R/V Falkor was not an issue. Furthermore, HQ-60 operators programmed the vehicle to perform a specific flight pattern at various elevations. This program ensured that the vehicle could replicate the pattern as often as needed. The HQ-60's maximum payload capacity of 20 lbs. put the researcher’s skills to the test. However, three years of effort culminated in a custom design which fit into the HQ-60’s payload bay.  

Payload choice

Researchers selected Hyperspectral cameras to record varying colors of the water in high wavelength resolution. By correlating ocean colors with the chemical and biological composition of the samples, the team linked oceanic processes with the color spectrum of seawater. With this information, researchers can use satellite imagery to calibrate ocean color and connect them to specific biochemical processes. The HQ-60, can map vast ocean areas with no disturbance. Plus, the HQ-60 performed these operations at very little cost and at unprecedented speed, rate and efficiency.  

The operation

The team prepped the HQ-60 and, using its VTOL systems, launched from a 40 foot by 40 foot area. Once it autonomously transitioned to forward flight, the aircraft remained near the ship as system functionality Upon completion of the system check, the aircraft traveled up to 6 miles away to take readings of the SML over undisturbed water. Typically, data collection operations lasted 3 hours. Once completed, the aircraft traveled back to the ship, completed a final systems check and landed on the deck of the Falkor. The unique design of the HQ-60 --  with its compact size, payload capacity and flight endurance -- makes it a reliable solution for a variety of missions.

Multi-Rotor or Single-Rotor: Which choice for your next project?

Although multi-rotor drones get most of the attention in the UAV world today, they’re not the only option for a flight project. But why would someone choose a multi-rotor over a single-rotor...or vice versa? Read on to learn the differences between the two, as well as their strengths and weaknesses. A key difference between the two, not surprisingly, is the number of rotors each offers. A multi-rotor aerial vehicle has several rotors that keep it airborne. In contrast, a single-rotor vehicle has one rotor plus a tail rotor to control its heading.  

Multi-Rotor

A multi-rotor is a good choice for operators who need to get a camera in the air for a short period of time. Multi-rotor drones are best for aerial photography and aerial cinematography. One of the advantages a multi-rotor is its high-degree of control over position and framing for aerial shots. However, a downside is speed and endurance limitations. Multi-rotor's high-level of stabilization comes with a constant need for fast and high-precision throttle changes. As such, Rules of aerodynamics dictate that the larger a rotor blade, the slower it spins, resulting in more efficiency. As such, a quad-copter is more efficient than an octo-copter but less efficient than a single-rotor. Flight time isn’t due to battery, but rather weight. There are options to help increase flight duration and payload capacity. A brushless motor for a heavy-lift electric multi-rotor is the best option for longer flight time and zero-vibration operations. If an operators wants the drone to stay airborne longer with a more substantial camera attached, a brushless motor for heavy-lift electric multi-rotor is your best option for longer flight time and zero-vibration operation.  

Single-Rotor

A single-rotor helicopter or other airborne tech project offers greater efficiency than a multi-rotor. Currently, single-rotor vehicles fill a small niche in the drone world. Single-rotors offer certain advantages. Remember the rules of aerodynamics? A single-rotor helicopter allows for longer blades to enable slower spinning and therefore expend less energy. Some applications require extended hovering, heavy payloads and/or long endurance. In these instances, a single-rotor may be the right option. However, single-rotor helis also have disadvantages. One knock is that they have significantly more vibration than a multi-rotor UAV. The larger blades also pose more danger. If a single-rotor UAV loses its overhead blade, the aircraft doesn't feature the fail safe of additional propellers. Whether flying a multi-rotor or a single-rotor, quality parts and components are vital for safety and performance.

Reforestation at Industrial Scale Possible Via Drone?

A former NASA engineer is harnessing the potential of drone technology for a very ambitious project. The project? Ecosystem restoration. More precisely, scaling reforestation projects to a size previously unimaginable. The goal? Plant 1 billion trees every year...via drone. Lauren Fletcher spent 20 years at NASA as an engineer before founding BioCarbon Engineering. The startup's entire focus is reforestation. More precisely, reforestation via the use of drones. BioCarbon Engineering plans to combat deforestation and restore global forests with a unique solution. Their platform takes the best data available and enables local specialists to restore their landscapes both quickly and affordably.  

Industrial-scale Combating Clear-Cutting, 1 Billion Trees at a Time

Advancements in technology facilitated the large-scale harvesting of forests. Now, in a process known as clear cutting, acres of forests are harvested in a single day. Each year, it is estimated that clear-cutting is responsible for the disappearance of 26 billion trees around the world. Reforesting such vast areas is a challenge. The end result? Trees are cut down much quicker than they are replaced. Industrial-scale deforestation around the world is threatening to upset the ecosystem’s balance. To combat the danger, reforestation projects continue to gain prominence. Through various initiatives, many countries are actively working to replace trees. Traditionally, reforestation is done by hand. On average, a single individual can plant 3000 seeds or saplings in a day. This method is labor intensive and time consuming which makes closing the gap on deforestation frustratingly slow. BioCarbon Engineering believes technology holds the answer. Drone technology can speed up and improve the process of replanting trees. They hope to improve the replanting rate to a projected 36,000 plants per day...or 1 billion trees in a year. Because terrains can vary, using drones to plant trees and regenerate forests is not meant to replace the human element, but complement it.  

Reforestation via Drone?

BioCarbon's plan? Modify consumer drones so they can plant seeds and tree saplings. But that's just the start. What follows is a simple, yet clever way of using the drones to improve the speed and efficiency of replanting efforts. First, drones fly over a potential site, take photographs and conduct an aerial surveys. The team then creates a 3D aerial map and a "seeding" plan suitable for the terrain. The team developed specialized pods which contain germinated seeds packed in a nutrient-rich substance. These bio-degradable pods sustain and protect the young plant until it can take root. The pods load into a pressurized canister aboard the drone and fire into the ground. Drones fly a path that is roughly 3-6 feet above the ground. The number of drones in operation depends on the size of the site. BioCarbon estimates that just two drone pilots operating multiple UAVs can plant up to 36,000 saplings a day. If successful, the company’s approach would significantly improve global reforestation efforts.  

Replacing Tree Losses on a Massive Scale

Today, some of the highest rates of deforestation occur in Latin America, Brazil, Malaysia, and the Philippines. Additionally, parts of Africa face the same issue. This may explain why Fletcher and BioCarbon are targeting projects in South Africa and the Amazon jungle first. In addition to improving reforestation efforts, drones can also access areas that are inaccessible to humans. Plus, BioCarbon believes this technology can help improve the overall health of local ecosystems. For example, pods can help spread various fungi and micro-organisms that improve soil quality as well as diversify the species of trees replanted in the forest. The efforts of BioCarbon is another example of drone use for humanitarian purposes. The company’s goals align with the UN’s plan to restore up to 300 billion trees by the year 2030. And, tree planting drones may just bring that goal within reach.
