South Carolina Waters Expedition--A Key Piece Of Grant Funded Equipment Has Arrived

Charleston is home to some of the busiest waters on the southern coast from the daily flow of massive ocean-going container ships to the hundreds of considerably smaller paddleboarders leisurely gliding in and around its estuaries and beaches. Add to this, a cruise ship will periodically slip into port with its load of vacationers hungry to soak in the city's harbor views and peninsula history. For sure, there is a lot to be experienced above water level, but silently overlooked is the abundance to be discovered and shared below its murky coastal waters, historically and ecologically.

Compared to clear water, murky water is characteristically home to an abundance of living organisms, including phytoplankton (a flora of freely floating minute organisms and a key part of oceans, seas and freshwater basin ecosystems) and zooplankton (jellyfish, crustaceans, and other ocean-wandering animals). Sediments also play a role. Along certain coasts, easily agitated finer particles like sand and silt will stay afloat for longer periods adding to the water's murkiness. On the other hand, the sediments off clearer coasts may be heavier and coarser. Instead of fine sand, these sediments are often made up of things like pieces of shells and chunks of dead coral, which are often tougher to stir up. Murky Bulls Bay of the Cape Romain National Wildlife Refuge contains the cleanest, richest waters in the world. Notably, Charleston's waters are also rich with the oozy, gooey, viscous substance locals fondly know as pluff mud.

This is the kind of environment the exploration team of the South Carolina Waters Expedition will be performing in as they explore Charleston's waters from salty coastal marshes up brackish tidal rivers for a glimpse of its sunken ships, flooded ghost towns, submerged relics, and unique marine inhabitants. To see in this type of ecosystem, the team will need some specialized equipment. This key piece of equipment to augment the team's visual capabilities has finally arrived--the OpenROV Trident.

Outfitted with a 1080p camera protected by a hardened sapphire lens, the Trident will provide the essential instrumentation for acquiring the fascinating videography the exploration team plans on sharing with its interested parties and followers. Specifically optimized for underwater filming, its great low-light performance and a wide viewing angle supported by advanced color correction algorithms will further allow the exploration team to observe Charleston's diverse aquatic life and collection of hidden underwater treasures in all its murky colors--ideal for exploring its nutrient rich estuaries and tidal rivers.

The Trident can be extended to include custom sensors or modules as add-ons which can be bolted to the payload area and interface with the main vehicle via WiFi. A phone or tablet can be used to control the drone and stream live HD video.

It will take some practice sessions to master Trident's highly tuned electronic speed controller with its rugged brushless motors capable of reaching speeds of up to 2 m/s for a quick descent as far as 300 feet or glide silently at slow speeds to carefully observe the murky and mysterious underwater environment it will be traversing.

Enjoy the expedition team's first video of team leader Dave Eslinger unboxing and showcasing some of the Trident's features, and stay tuned for upcoming videos of practice sessions as the team familiarizes themselves with its advanced autopilot features and fine tunes their operating skills.
