Description

Inventory of fluid and filter samples collected for carbon composition and isotope analysis during R/V Atlantis cruise AT39-01 at North Pond IODP CORK observatories U1382A and U1383C.

Methods & Sampling

Detailed methodology for fluid recovery described in (Meyer et al., 2016).

All fluids transferred from sampling bags by peristaltic pump through Masterflex Bio-Pharm silicone tubing and PFA or PVDF fittings. All tubing and fittings precleaned with in 10% HCl and rinsed with MilliQ water.

Whole water samples transferred to pre-combusted amber glass bottles and sealed with PFTE-line lids and stored frozen at -80°C.

Samples meant for DIC and alkalinity measurements sampled according to NOSAMS protocol (http://www.whoi.edu/fileserver.do?id=75006&pt=2&p=75096). Poisoned samples stored at room temperature in the dark.

Samples meant for DOC analysis were filtered through pre-combusted 47 mm Sterlitech GF75 filters into pre-combusted amber glass bottles sealed with PFTE-lined lids. Sampled stored at ‑40°C until analysis.

Filters collected at the seafloor by the Mobile Pumping System (MPS) described in (Cowen et al., 2012).

Fluids filtered sequentially through 5 µm nylon woven mesh (Spectrum Labs), Whatman GF/F and Sterlitech GF75 and stored frozen at -80°C wrapped in pre-combusted aluminum foil.
