TABLE 4.

Photosynthetic carbon allocation in phytoplankton under different sea ice conditions.

	Ice-free and intermediate regions	Ice-heavy regions
LMWM (low-molecular-weight metabolites) (%)	11.0 (16.8)	26.0 (14.4)
Lipids (%)	24.3 (21.7)	41.5 (14.7)
Polysaccharides (%)	26.7 (20.2)	10.1 (8.5)
Proteins (%)	37.9 (22.5)	22.4 (15.0)

The experimental stations were divided into two regions: ice-free and intermediate regions and ice-heavy regions, following Yun et al. (2012). Ice-free (<10% ice coverage) and intermediate regions (30–60% ice coverage) (n = 13) (a) and ice-heavy regions (>80% ice coverage) (n = 5) (b). Mean values are given (standard deviation in parentheses).
