Hello my friends, my colleagues, my bretheren, mis amigos, my fellow scientists.

Tomorrow is the day we conduct our experiment. As a result, I thought it necessary to do a bit more research, and to make another update to our records. Also, a proposal for a chemical analysis would also be useful (if not necessary!) at this point.

So, firstly I'd like to extend a gracious thank you to Mr. Marine for his extremely informative post. As a general extension of his thinking, I'd propose (as we were discussing earlier today) that we should indeed focus not only on bull kelp, but on different kinds of seaweed in general. Perhaps, as according to his post, the different "coloured" seaweed in relation to the bullkelp (i.e. compare the bullkelp to two other kinds of seaweed and find the points of comparison/contrast).

The next obvious question is what our experiment should entail. Well, according to my research, bullkelp can grow to be anywhere from 30m-80m long -- from the kelp floating in the bay, I find it hard to believe that this is the case around Pedder Bay! Nevertheless, the kelp we have generally are attached to rocks at the bottom of the bay. The types of seaweed that Mr. Marine has told us about (and I hope that at least a few of the species are local to our bay) share the same characteristic, as both bull kelp and seaweed are an important part of the underwater forest. Therefore, I would propose an experiment that compares the amount of force required to separate a bullkelp from a surface it has attached to to that of seaweed. If this is not viable (i.e. we cannot study the aquatic animals when they are still attached to something), perhaps an investigation into how much force can be applied in equal but opposite directions on the marine animal before it is torn in half (as Mr. Marine said, this can vary greatly between species).

Then, the bullkelp is topped (as has been previously mentioned by both Mr. Marine and Alex) with a pneumatocyst (that is, a large bulbous sphere on one extreme of the bullkelp). Inside of this bulbous sphere is carbon monoxide gas. Evidently, it is used for buoyancy so that the blades can reach towards the surface of the water for photosynthesis. I would therefore propose a second experiment we can conduct as another point of comparison between why the bullkelp has such a large pneumatocyst whereas the seaweed does not, yet they both photosynthesize. Perhaps on a technical note, the amount of CO in the bullkelp, or on a more practical level, simply a research inquiry into why this might be from multiple perspectives?

As a final note to consider (and possibly a third research project or experiment), I thought it would be interesting to perhaps find a connection between the different chlorophylls the seaweed contain (as some contain red, blue or brown pigments, as Mr. Marine said) and the place in which the seaweed and bullkelp is found. Just something to think about.

So, this is the research that I've found thus far, and the experiments that would logically accompany them. I believe if we follow them tomorrow, we will be able to explore the relationship between the four sciences on a deeper scale.

Cheers, my friends!
