Acadia National Park - Floating Classroom: Good Data

The video tutorial explores the dynamics of a water column, focusing on temperature and dissolved oxygen levels from the surface to the bottom. It discusses the seasonal changes affecting these parameters, leading to stratification into layers: epilimnion, metalimnion, and hypolimnion. The tutorial explains how density differences create barriers to mixing, affecting oxygen distribution. It also highlights the role of sunlight and plankton in influencing oxygen levels, emphasizing the importance of understanding these factors for assessing lake health and productivity.

How does sunlight influence the distribution of dissolved oxygen in the upper layers of a lake?

What role do phytoplankton play in the oxygen dynamics of a lake ecosystem?
