| Resumo |
Water samples were collected from pre-dawn CTD casts at 5 depths corresponding to 55%, 20%, 7%, 5% and 1% of surface irradiance. 1 litre water samples wrapped with optical filters to replicate light levels. Spiked with 200 µL of 13C labelled sodium bicarbonate. After 24 hourse filtered through ashed 25mm GF/F (Whatman) filters, rinsed with HCl solution (1-2%) and stored at -20oC. On shore encapsulated in tin capsules and analysed for 13C isotopic enrichment. Carbon uptake rates calculated using the equations of Fernandez et al. (2005). |
