Title of dataset | Time-series physical and chemical transports through the Rockall Trough (2014-2018) |
Narrative summary of dataset | Monthly-averaged transport time-series: volume, temperature, salt, nitrate, phosphate, silicate, dissolved inorganic carbon and total alkalinity. |
Summary of processing methodology | * Moored time-series (temperature, salinity, and pressure) calibrated using standard cal-dip protocol. * Section CTD data were calibrated using bottle samples. * Water samples were analysed for dissolved inorganic nutrients, dissolved inorganic carbon and total alkalinity. * Multiple linear regression equations were derived using data from the AR30-04 cruise in July 2018 (R/V Armstrong, 1st-30th July 2018). These link dissolved inorganic nutrients / dissolved inorganic carbon / total alkalinity and temperature, salinity and pressure. * Multiple linear regression equations were applied to calibrated moored time-series to calculate derived time-series of dissolved inorganic nutrients, dissolved inorganic carbon and total alkalinity. * Time-series were low-pass filtered to remove tidal oscillations, interpolated onto 12-hourly time-steps, and a regular pressure grid. * Volume transports were calculated from moored CTD and current meter records. * Nutrient and carbon transports were calculate by multiplying volume transports by derived moored nutrient and carbon fields. * Temperature transports were calculated by multiplying volume transports, by interpolated moored temperature fields, and by potential density, and specific heat of seawater. * Salt transports were calculated by multiplying volume transports by interpolated moored salinity fields. |
