Ryan,

I like what you're doing w/ your container. Just bit concerned on robustness but I think your raft will be the help. Look forward in your raft design. Nice work!

Mark got really good suggestions.

Hi Ryan, It looks like you are handling the water challenges of your project very well. Will your raft be tethered in position so that the solar panel remains tilted towards the sun? If so, how will your tether accommodate the waves and tides? Mark makes some really good points with respect to the seals being in jeopardy if the down pipes can move. If you put rigid porous planes between the pipes you will lock the pipes into place and not create too much drag.

If you are having trouble with sealing the upper pipe, you could add a u section so that any water would have to travel upwards before entering.

This would ensure that wind blown water is not resting against your seal.

I'd be inclined to add something tying the colour sensor and disolved oxygen pipes together to stop the wave action working at the seal.

The last thing you need is water inside and damaging your electronics.

I presume you will be adding some bouyancy inside as the last precaution.[View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-755dbb8c-4a1b-43bc-a2c1-d995efa1e46a/contentimage_5F00_2516.png:16:16]

Is the upward pipe designed to keep water from entering the box? Good work! It would be interesting to see in action.
