|Title of dataset||Time-series physical and chemical transports through the Rockall Trough|
|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, pressure and dissolved oxygen) calibrated using standard cal-dip protocol, or in the case of dissolved oxygen using nearby post-deployment and pre-deployment CTD profiles.
- Section CTD and oxygen sensor 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 linking dissolved inorganic nutrients / dissolved inorganic carbon / total alkalinity and temperature, salinity, pressure and dissolved oxygen.
- 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.|
