The invention relates to a container assembly comprising a container for depuration of mollusks and a drain canal unit. The assembly provides a closed circulation of water via a circulation route that has an entry portion between the floor of the container and the drain canal unit, a circulation channel between the corner of the container and a drain canal unit, and a drain canal within the drain canal unit. Also provided is a drain canal unit for use in stackable containers that provides circulation of water within a container assembly.

A variable buoyancy platform including a support frame with a platform floor mounted to a top thereof. A plurality of bottom variable buoyancy tanks are disposed below the support frame and mounted thereto. Each bottom variable buoyancy tank includes an opening disposed in a bottom portion thereof and an air conduit port disposed in a top portion thereof. At least two side variable buoyancy tanks are disposed at opposite sides of the support frame and pivotally movable mounted thereto. Each side variable buoyancy tank includes an opening disposed in a bottom portion thereof and an air conduit port disposed in a top portion thereof. A bottom air conduit system is connected to the air conduit port of each bottom variable buoyancy tank. The bottom air conduit system is adapted for controllably providing air to each bottom variable buoyancy tank and for controllably releasing air from each bottom variable buoyancy tank. A side air conduit system is connected to the air conduit port of each side variable buoyancy tank. The side air conduit system is adapted for controllably providing air to each side variable buoyancy tank and for controllably releasing air from each side variable buoyancy tank.

Disclosed are a marine ecological engineering construction method, an asphalt cement-based coating, and a preparation method thereof. The asphalt cement-based coating can make discarded concrete have the capacity of inducing the settlement of sessile organisms, achieve the purpose of using discarded concrete to construct ecological engineering, and has the characteristics of discarded object recycling and marine ecological restoration.

Methods, systems, and computer-readable media that implement a mobile filtration system that provides sustainable, on-demand water filtration while supporting the growth and maintenance of organisms. The method includes determining an environmental parameter associated with a volume of water, determining, based on the determined environmental parameter, a control parameter for an autonomous submersible structure that includes a platform on which marine life grows, and generating, based on determining the control parameter, an instruction for the autonomous submersible structure.
