Full details will be presented and discussed elsewhere once all data are analysed. Ammonia excretion rates increased proportionally with dry body weight of the zooplankters (2-107ng NH_4-N ind^<-1> h^<-1>). Ammonia accounted for 60% of DIN in the water column. DIN was 23-45 times more concentrated in pore water than in overlying water, promoting effluxes. Preliminary estimates of ammonium flux across the sediment/water interface through demersal zooplankton excretion, using the present rate-data and published population density estimates, suggest a mean rate of 46μM NH_4 m^2 h^<-1>. This represents approximately 1% and 24% of the ammonia stock in the lower water column and upper substrate respectively. Values exceed those determined for meiofauna, and are approximately 30% of those estimated for heterotrophs in the water column.","subitem_description_type":"Abstract"}]},"item_4_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"高知大学海洋生物教育研究センター","subitem_publisher_language":"ja"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03879763","subitem_source_identifier_type":"ISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10778872","subitem_source_identifier_type":"NCID"}]},"item_4_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Bishop, W.
