Scientist Research


Andre W. Visser is a Professor of Physical Oceanography in Denmark, at the Technical University of Denmark. I chose this scientist because I have always been interested in marine biology and I had never heard of biomixing( the action  of swimming organisms in mixing the worlds oceans) and it caught my eye.

The journal I read was debating biomixing the oceans with small organism. It is contemplating if small organisms are exerting enough energy to make up for the heat they are putting off. The article also posses the question that if the small amount of mechanical energy can substantially mix the water. It tells that biomixing is controlled by "the scale at which turbulent kinetic energy is imparted to the flow", "equivalent to the rate of work done",and "a measure of the stratification of the water column" and how each of these factor into the equation. The article concludes in saying that small organism do not have great enough efficiency to sufficiently mix the oceans.

I have many questions about the article including: What made you want to research biomixing? What type of tests have you done on this? Is there a substantial difference between different small organisms? Have you tested this with larger organisms? and finally Do you think that it would be harder to get larger organisms to swim at a consistent rate?
