Pore-water nutrients

Abstract

This data gives the concentration of nutrients in sea water samples from the water column and from sediments (pore-water) taken in the North Sea. Includes measurements for Nitrate (NO3) Nitrite (NO2) Phosphate (P04) Silicon (Si) and Ammonia (NH4)

Lineage

Samples from the water column were collected by Niskin bottles deployed on a CTD 'rosette'. Pore-water is the sea water held in the pore-spaces of marine sediments and was sampled using a sipper system from 11 depth horizons in undisturbed sediment cores collected by a NIOZ box corer. Resulting water samples were filtered and analysed using a Skalar nutrient analyser. This data is used to determine where and how organic matter is decaying, as well as analysing sediment linkage to macronutrient cycles (N, P, Si) via nutrient fluxes or uptake across the sediment-water interface. Samples were collected in the North Sea during three cruises on RV Cefas Corystes (Cruise Codes CORY 10/2001, CORY 09/2002 and CORY 8x/2003)
