Responsible Collection

[Humu-out-of-Water]

Hi!

I'm a diver and a high school teacher who who is working on an Oceans class. (It's not an official "science" class). I plan to collect samples of of ocean water when I'm there as was considering collecting other samples... I need input please:

1. I want to be responsible in what I collect (I won't be collecting fish any whole specimins or killing anything). What IS acceptable?

2. Is it ok to collect a kelp leaf?

3. How should I collect water at depth? Plastic bag?

Any other FRIENDLY input would be helpful. While I've consulted with our schools science teacher, I myself am NOT a science teacher. I teach special ed.

What I plan to do with these things depends on what I collect. For example we will compare sea water from depth and from the surface.

Thanks!

A small plankton net would give you plenty of microscope critters for your students to observe.

I do a lot of CTD casts. These are instruments that are lowered and record conductivity/temperature to get salinity, depth, disolved oxygen, turbidity and flourometer readings to get chlorophyll. We take water samples at various depths with the instrument. PM me if you would like copies of some casts.
