Lake Malawi

Apr 12 Plan is to look for new Places to collect ornamental fishes. These can be collected from 0 to arround 40 meters by hooka-system. Additional info: Lake Malawi is the most southern of the African Great Rift Lakes. It is shared by the countries of Malawi on the western and southeastern shores, Mozambique on the central eastern shore, and Tanzania along the northeastern shore and at the extreme northwest. It is the third-largest lake in Africa (31,000 km²; 603 km long × 87 km wide), and the tenth-largest in the world. Its surface is around 474 meters (1555 feet) above mean sea level; its maximum depth is some 704 meters (2310 feet), making it the world's fourth-deepest lake.

Westward Bound-Springfield To San Francisco Liveaboard Experience

Apr 12 Prepare a vehicle for a road trip to San Francisco with completed OPENROV #236 and Scuba Gear to create new adventures and join in on the fun. Will be living on a sailboat in the Sausalito Bay during the month of May! Will be conducting experiments on sonic communication via ROV. Hope to visit HQ and see the latest. No one has made such a journey since Clark Griswold.

Return to Fayetteville Green Lake

Apr 2 I'm planning to continue my research of meromictic lakes with a group from the State University of New York College of Environmental Science and Forestry. We will map the bottom of Fayetteville Green Lake using side-scan sonar and I will be bringing two OpenROVs to explore the nooks and cranies of this tiny little gem. Meromictic lakes are very small and surprisingly deep, preventing seasonal mixing of the layered water. The top layer functions normally, but the bottom is an oxygen depleted environment in which few organisms can survive. This is a rare but naturally occurring phenomenon.

The Lost Dakota

Apr 2 September 11 1945. A RAAF Dakota C-47 takes off from Milne bay airstrip. 19 men are on board. It is pouring down. 20 min later the plane is never heard from again. December 2011. A group of 4 Explorers from Australia, Norway and Denmark took the challenge and located parts of the wreck in the bays mucky & croc infested waters. Due to time and equipment, we never finalized the search. We want to go back, find the remaing parts and do a documentary of the wreck and the families left behind.

Exploration of the Steamer Tahoe Shipwreck

SS Tahoe Shipwreck, Mar 30-Apr 9 In 1940, the 52m long "Steamer Tahoe" was skuttled in Lake Tahoe, Nevada in 150m of water. Hardly anyone as seen the steamship since. We intend to use OpenROV submarines to record video of the sunken ship and examine her condition.

Jardines de la Reina

Cayo Caballeros, Cuba, Apr 16 The 'Garden's of the Queen' is an archipelago of small islands, mangrove lagoons, and a coral reef 50 miles south of mainland Cuba. In May I plan to take an OpenROV with me and examine the deeper coral structures which are unreachable by scuba. There was an american submersible expedition which surveyed the reef in 1997. A comparison study will give us an idea for how the reef has changed over the recent decade. Fun Stuff! Oh, and it's legal.

Return to the Molly Rose

Tree Island (or Sandy Island), Mar 27 Over the marinas stony breakwater, we could see her upper hull and breathed a short lived sigh of relief. We saw, on closer inspection, she was more on the rocks than behind them and had a large hole in her hull. It has now been 2 years since we sunk her, in the bay off Tree Island, our favourite destination. Time to take a look.

Tulum Cave Diving

Feb 8-Feb 12 With no particular plans, I am going to bring a new v2.6 OpenROV to Tulum, Mexico- a place riddled with countless underwater 'cenotes' (underwater caves) that have been largely unexplored.

Sea Star Search in Monterey

Monterey Bay, Feb 6-Feb 13 Up and down the west coast, sea stars are disappearing. The phenomenon has been called sea star wasting syndrome, and we still don't know a lot about it. We're going to participate in the citizen science project to help record the condition od sea stars in Monterey Bay.

Sea of Cortez

San Francisco, Nov 8-Mar 4 Almost 75 years ago, John Steinbeck, Ed “Doc” Ricketts and a group of others took a trip down the California coast, around Baja, and into the Sea of Cortez. We're going back. And we're bringing all our new DIY/maker tools to put to the test.

Recent Observations

Why send an ROV instead of a human? Answer #1 Teeth During my reconnaissance mission to Cuba this week, I picked out a few key places to test the ROV when it's ready in May. Among the dive sites I've chosen are some deep coral canyons which are below diver depth. However, depth is not the only reason to use an ROV. Potential danger could also be a deciding factor in when to deploy a bot, in this case, could an ROV be a better choice when interacting with wildlife? Other ideas on when to choose an ROV over a human?

All my trips are based at a collectingstation in Chipoka where we sail out from to the different Places. Plan is to use Fisfinder/Plotter to find reefs and then deploy OpenROV to explore , this saves a lot of time compared to going in with scuba. Following equipment must be small, handy and have low power consumption: Fishfinder/plotter combo OpenROV (Of cause!) My own stand-alone DIY logger (In development): Water values: Ph, ORP,Conductivity, temperature. Above water: wind speed and direction, Rain, Light in Lux and RGB colours, Pressure (mbar), temperature and humidity. A camera is taking pictures of the lake for comparison to data on it's own SD. All measurements are marked by time taken from a RTC Solar-charger as backup for uC (6A LiPO) Data stored on uSD Some kind of solar charger as most collecting trips easily are 5 days at remote Places without electricity and just sleeping in a tent on the Beach.
