Abstract In winter, lakes and lagoons at high altitudes or latitudes have interesting hydrological cycles that differ from those in other seasons regions, because water surfaces are covered with ice. Hydrological balances of complex dynamic systems, to elucidate them, isotopic tracers been used as effective tools along observations precipitation, evaporation, inflows, outflows. Here, understand processes during freezing periods the brackish Saroma‐ko Lagoon, Hokkaido, northern Japan, we...
This study investigated the changes in sea ice temperature, microalgae species distribution, shape changes, and photosynthetic activity observed first-year that forms winter Saroma-ko Lagoon, Hokkaido, Japan. Temperatures at bottom of remained constant -1.7°C, near freezing point, while they varied between -6 -1°C with diel fluctuations surface layer. Carefully collected algal samples showed high quantum yield acclimation to light intensities individual layers; this indicates responds...
