Answer to coral survival in deepwater

Did you know that corals need sunlight to survive. Corals are actually animals, with tiny, tentacle-like arms that they use to capture their food from the water and sweep into their mouths. Most corals also contain algae called zooxanthellae (pronounced zo-UH-zan-thuh-lay), which are plant-like organisms that need sunlight for photosynthesis to produce its own food / energy. The “animal” corals and “plant” algae each benefit from their symbiotic relationship, even at depths of 30m to 150m, where sunlight is scarce.

In deepwater environments, researchers from Curtin University have found that reef-building corals survive by kicking into ‘photosynthesis overdrive’ to enhance their ability to gain energy from sunlight and by upping their intake of microorganisms.

Blue Trail Engineering’s ASV is travelling from California to Hawaii

Our partner Blue Trail Engineering launched an oceangoing ASV from Avila Beach CA on February 8, 2025. Destination: Hawaii. 

The vessel uses all Blue Trail Engineering components: MTR-2000 thruster, servo SER-2020 rudder, and all Cobalt cables and connectors. 

“If the boat makes it to Hawaii, it will demonstrate the reliability of our products.  If it doesn’t make it to Hawaii, we’ll blame it on sharks or pirates.”
