This fish-zapping robot is hunting invasive lionfish in coral reefs

Despite advancements in technology in most sectors of life leading to an increase to access of information about practically anything, little is still known about the ocean and its behavioral patterns. Liquid Robotics – a Silicon Valley-based company – is trying to change that. Engineers here have created the "Wave Glider," which essentially acts as a router within the ocean powered by wave energy and solar panels. This invention can transmit data on tectonic activity that has the potential to predict tsunamis.

New DNA testing technology is showing promise as a faster, cheaper way to determine if a shark fin came from a protected species, an important task to curbing the illicit shark fin trade across the world. While experts warn that the technology won't act as a deterrent to the practice, it will help authorities better track and determine if shipments are suspect.

In Jamaica, locally-led coral nurseries are working to restore the coral reef that have been lost to natural and manmade disasters. These organizations have small coral gardens where they can grow free of danger and when they’re big enough, are transported to a reef. With coral and fish being so codependent in the underwater ecosystem, the regrowth of coral has meant an increase of fish and fishing for the country, which many people rely on for their livelihood.

In Londonderry, New Hampshire, the Carriage Shack Farm hire out goats to eat unwanted plants like poison ivy or bittersweet. Contrary to humans, they aren’t harmed by the plant and actually enjoy eating it. Prior to being hired, the farm trains the goats so that their appetites and stomachs aren’t adversely affected.

For years, a rancher in Southern Oregon has been trying to keep a local pack of wolves from killing his livestock, and after many rounds of trial and error and collaborative efforts, a high-tech fence may be the solution. Although the fence isn't cheap, many came forward to help make this a possibility and show their support for a project that united people that historically have stood politically opposed.

In Arizona, the use of drones as farming technology is gaining traction. While still in the early stages, drones have shown to help with field mapping and data collection on things like crop conditions, water quality, and infestations. In an area that has been experiencing a 2-decade drought, these drones are able to help identify more precisely the water needed for soil.

Local Ocean Conservation is in Watamu, Kenya has made approximately 21,000 turtle rescues and "treated more than 650 turtles in its rehabilitation center and clinic" since it's inception in 1997. The group responds to fishermen who have accidentally caught turtles in their nets and then remunerates the fishermen for their "time, effort, and phone calls." This incentive-based relationship combined with a ban on the international tortoiseshell trade has helped decrease the poaching of turles, and the group has now expanded their efforts to include more initiatives to protect the endangered species.

Radar, lidar, and sensors guide the world’s first autonomous tram across Potsdam. While not yet commercially viable, the tram is an advancement in driverless technology. It can respond to road hazards faster than a human and runs on energy from wind and solar.

Beavers and the dams they build have been found to be tools against climate change as the planet’s temperature continues to rise. Dams slow water down and allow it to seep into the Earth, providing groundwater for humans, and also cools down both water and air temperatures. Beaver dams also create wetland ecosystems that are practically resistant to wildfires.

The Ecosphere Restoration Institute received $5 million from the Florida State Legislature to restore the declining seagrasses on 100 acres of the coast. The organization partnered with experts who have permits to harvest the seeds, grow them in a nursery, and replant them in shallow areas. The project will also help prevent manatee deaths, as the animal depends on seagrass as a food source.
