Calcifying phytoplankton standing stocks in the North Pacific from the R/V Kilo Moana cruise KM1712


This dataset compiles the CaCO3 standing stocks of living coccolithophores (mg/m³), of detached coccoliths (mg/m³) and the integrated CaCO3 standing stocks of coccolithophores (mg/m²). The samples were collected in the North Pacific between Hawaii and the Gulf of Alaska during the R/V Kilo Moana cruise KM1712 in August 2017, with rosette Niskin bottles equiped with CTD (Sea-Bird SBE 9) at different depths throughout the photic zone including the deep chlorophyll maximum. To estimate the CaCO3 contribution by coccolithophore assemblages in each sample, we carried out the transformation of coccospheres in number of coccoliths, following the estimates by Yang and Wei (2003), and then we adopted the coccolith mass estimates by Young and Ziveri (2000). The coccolith mass of Noëlaerhabdaceae also took into account the estimates by Beuvier et al. (2019) considering different mass for E. huxleyi calcification degree.

Jess F. Adkins and William M. Berelson were chief scientists of the Kilo Moana cruise KM1712. Patrizia Ziveri and William R. Gray designed the sampling strategy. Alessandro Incarbona and Michaël Grelaud estimated the coccolithophores and coccoliths CaCO3 standing stocks.
