Table 1 Matrix documenting how different environmental variables and processes may potentially increase or decrease rates of Si(OH)4 utilization over the analysed interval at ODP Site 1098A.
From: Temporal controls on silicic acid utilisation along the West Antarctic Peninsula
Environmental variable | ↑ Si(OH) 4 utilization | ↓ Si(OH) 4 utilization |
|---|---|---|
↑ Sea ice (↑ F. curta) | ↑ Spring stratification ▸ ↑ productivity | ↑ Brine ▸ ↑ UCDW/nutrient onto shelf |
↑ Solar irradiance | ↑ Summer stratification ▸ ↑ productivity | — |
↑ SWW | — | ↑ UCDW/nutrient onto shelf |
↑ Glacial discharge (↓ δ18Odiatom) | ↑ Spring stratification ▸ ↑ productivity | ↑ nutrients (glacial flour) and/or ↑ autumn and winters sea-ice formation ▸ ↑ UCDW/nutrients onto shelf |
