in agreement with the results reported by Ittekot et al. [29] and Liebezeit [30] and
indicate that the carbohydrates in the sampled POM are more résistant to microbial dégradation.
In contrast, total protein concentrations decreased significantly with depth. At
stations 23 and 25, total proteins in the aphotic layer were about 10 times lower
