Wood, leaves, algal clumps and other particulate organic matter (POM) enter the Great Lakes from streams that flow into it. I'm curious how important these inputs might be to lake carbon budgets. Has anyone quantified stream POM inputs or modeled this? I'm especially interested in Lake Superior.
First of all, I measured the DOM from stream to lake ecosystem, but not the POM. Of course, they play important role in organic matter bugdet in lakes. You can read my paper from the reference (Mostofa KMG, Yoshioka T, Konohira E, Tanoue E, Hayakawa K, Takahashi M (2005b) Three-dimensional fluorescence as a tool for investigating the dynamics of dissolved organic matter in the Lake Biwa watershed Limnology 6: 101-115).
POM play an important, specifically depending on the contents of different organic matters (wood, leaves, algae, etc) and subsequent decomposition in lake bed and surface. For example, alage can release DOM more quickly, but wood may release decompose for weeks to months in lake bed. This should be considered clearly. You can also read book "Photobiogeochemistry of Organic Matter: Principles and Practices in Water Environments" that publsihed by Springer in 2013.
