Abstract:

This dataset presents bulk organic geochemical data (TOC, d13C) obtained by EA-IRMS analysis on samples from a sediment trap deployed 20 meters above seabed in the submarine Baker River delta in the Baker-Martinez Fjord system, Chilean Patagonia (44-48⁰S). The samples were collected between January 2017 and January 2019 using a sequential sediment trap holding 24 bottles of 500 ml which were rotating every 15 days.
