Abstract

Using vertical profiles of temperature and in vivo fluorescence sampled between Tanhoy and Listvyanka, we show that temperature and fluorescence fluctuations exhibit specific levels of internal structuration that are independent of the overall vertical structure of the water column, which suggest a previously untapped small-scale biophysical coupling.
