The effect of melting treatments on the assessment of biomass and nutrients in sea ice (Saroma-ko lagoon, Hokkaido, Japan)
Melting of sea-ice samples is an inevitable step in obtaining reliable and representative measurements for biogeochemical parameters such as inorganic nutrients and particulate matter. The impact of the sea-ice melting procedure has been previously evaluated for biological parameters such as chlorop...
