The palaeoceanographic history of the Celtic Sea since the last deglaciation and its potential for blue carbon storage
Shelf seas account for around 15-30 % of ocean productivity ; as such , shelf-sea sediments are potentially major stores of carbon . Shelf-sea hydrography and productivity is dominated by seasonal stratification ; however , stratification evolved with sea-level over the Holocene epoch on the UK shelf , and thus carbon stores will have changed over this time . This project investigates a core collected from the Celtic Sea , JC106-052PC , a 7.5m long marine sediment core recovered at a waterdepth of 116 m from the Celtic Sea as part of the BRITICE project . Preliminary multiproxy data from this expanded archive points to changing environmental conditions and productivity , potentially reflecting the evolution of seasonal stratification in the Celtic Sea over the Holocene . Work currently focuses on increasing the resolution and extent of the benthic foraminifera record . This study aims to increase our understanding of the shelf-sea dynamics and productivity of the Celtic Sea over the last deglacial to Holocene period . By elucidating the response of the Celtic Sea to changing sea level and oceanographic conditions , and its capacity to act as a carbon store , we can better understand the role of other shelf environments , potentially benefiting global studies of palaeoclimate and future climate change .
