Table 2. Holocene tephra layers in marine sediments on the Iceland shelf. Bold tephra layers are absolutely
dated tephra layers or tephra markers. Shaded tephra layers are tephra layers identified in more than one core
on the shelf. – Gjóskulög í sjávarseti á landgrunni Íslands. Feitletruð gjóskulög eru aldursákvörðuð, svokölluð
gjóskuleiðarlög. Skyggðum gjóskulögum hefur verið lýst í fleiri en einum kjarna á landgrunninu.
