Deployment - Considerations for frame design and deployment include: -Environmental (currents, flow variability, depth, bottom hardness, etc) -Deployment methods (divers, from shore, deep water, ROV) -Artifacts (flow obstructions, vibrations) |

Standard Frame - Peter Berg’s design Peter Berg’s frame (shown top right) was used at Eawag (bottom right). Peter’s drawings were changed to SI and slightly modified by Lorenzo Rovelli (PhD Student). Frame is designed to be light, and easily deployed by hand in relatively slow current speeds. Allows resolution of fluxes from all directions, however flux artifacts caused by flow past legs is still unknown. Hand drawn plans |

IFM - GEOMAR using ROV deployment The frame on the right is designed for deploying the EC by ROV in the extreme North Sea environment. Water body is tidally influenced, with currents ranging from 0 to 1 m/s. Concerns include vibration (either by frame, parts, or deployment ropes and buoys), as well as movement of the lander frame. Frame features include changeable feet... |
