Description

Methods & Sampling

Dataset acquisition description

A system with a Geotech in-line acrylic filter holder (142mm diameter) connected to a flowmeter was attached to the Underway water flow on R/V Atlantis and particulates were collected for approximately one hour. The filtration system was arranged to split the water flow between two filter holders/flowmeters to achieve dual sampling from the same water mass. One side contained a combusted Glass Fiber FIlter (GFF) and the other side fractionated the sample with a 51um pore size Nitex mesh and a 0.2um pore size Supor (PES) filter. The Nitex and Supor filters were cleaned with 5% for 4 hours and neutrilized to pH6 before use. Samples were collected at station and while on transit (between stations).

A Geotech in-line acrylic filter holder 142mm diameter was used along with a flowmeter for this dataset.

Data Processing Description

Dataset Processing Description

All geographic locations presented here were taken from the ship's R2R elog. The volume filtered was calculated from the difference between end and start flow meter readings.
