Abstract

These data include the sediment petrographic analysis for Amazon Delta and Sierra Leone Rise Sediments. These data were collected on multiple cruises in throughout the Atlantic; specifically, in the Amazon Delta (EN-480; July 2010) and Sierra Leone Rise (EN-481; August 2010). Sediments were collected using multi-corer and kept frozen until analysis. Sediments were analyzed quantitatively via microscopy by Dr. Bertrand Ligouis at the Laboratories for Applied Organic Petrology at the University o...

Sediment samples were collected via a 4-barrel multi-corer (R/V Endeavor, segmented into 1-2 cm sections, dried in a drying oven (35°C) and homogenized via mortar and pestle.

Instruments
Polished sediments were observed under a Leitz DMRX-MPVSP microscope photometer using a magnification up to 500X with reflected white light, uѵ fluorescence, plane-polarized light, and cross-polarized light.

Location: 
Amazon Delta (approximately: 4 N, 47 W; 2400-3500m); Sierra Leone Rise (approximately: 7 N, 20 W; 2800-3800m).
