Particulate Matters Flux and Standing Stocks of Ice Algae and Phytoplankton in Ice Covered Lagoon Notoro-ko

摘要

Lagoon Notoro-ko is open to the Okhotsk Sea and freeze during the winter. We conducted a winter investigation into the temporal changes of particulate matters flux and chlorophyll a in sea ice and water column during the ice-covered period from February 13 to April 5, 2012. We speculated that the majority of particulate matter flux during the sea ice growth phase originated from the phytoplankton in the water column. During the transition period the majority of the sinking particulate matter was considered to be ice algae, and during the sea ice melting period, ice algae and phytoplankton contributed to an increase of sinking particulate matter.
