Summary

This dataset consists of measurements of underway meteorology, navigation and sea surface hydrography as well as underway discrete salinity samples. A comprehensive survey of the Tropical Atlantic was undertaken between June and August 2017. Data were collected on RRS James Cook cruise JC150. Navigation data were collected using an Applanix POSMV system and meteorology and sea surface hydrography were collected using the NMF Surfmet system. Both systems were run through the duration of the cruise, excepting times for cleaning, entering and leaving port, and while alongside. 65 salinity samples were taken from the non-toxic underway supply. The non-toxic, pumped seawater supply intake was located 5.5 m below the sea surface. Sample analysis was completed using a Guildline ‘Autosal’ salinometer. This cruise formed the field component of NERC Discovery Science project "Zinc, Iron and Phosphorus co-Limitation in the Ocean (ZIPLOc)". The data were collected in order to determine the prevalence of zinc and iron limitation of APA in the phosphate deplete subtropical North Atlantic Ocean; to quantify the impact of zinc-phosphorous and iron phosphorous co-limitation on biological activity, specifically phytoplankton growth, primary production and nitrogen fixation; and to quantify the significance of zonc-phosphorous and iron-phosphorous co-limitation in driving phytoplankton productivity over basin scales and multi-decadal time scales. The Discovery Science project was composed of Standard Grant reference NE/N001079/1 as the lead grant with child grant NE/N001125/1. The lead grant runs from 02 January 2017 to 03 February 2017 and the child grant runs from 01 February 2017 to 31 July 2019. Dr Claire Mahaffey of University of Liverpool, Earth, Ocean and Ecological Sciences was the principal investigator of the lead grant of this project. Prof Maeve C. Lohan of University of Southampton, School of Ocean and Earth Science was the principal investigator of the child grant. The underway discrete salinity samples data and the underway navigation, meteorology and sea surface hydrography data have been received by BODC as raw files from the RRS James Cook, processed and quality controlled using in-house BODC procedures and are will be made available online in the near future.
