# from cruise AT39-01 on R/V Atlantis 2017 expedition to North Pond
# PI: Peter Girguis (Harvard)
# Co-PI: Sunita R. Shah Walter (Harvard)
# Version: 12 January 2018
# Sampling Notes:
# DIC samples collected, poisoned and sealed according to NOSAMS & WOCE protocol.
# DOC samples filtered through pre-combusted Sterlitech GF75 filters & frozen at -80C in pre-combusted amber glass bottles sealed with PTFE-lined lids.
# Whole fluids were sampled directly into pre-combusted amber glass bottles and frozen at -80C.
# Filters collected by fluid filtration on the seafloor by the MPS system, pumped sequentially through the 5 um nylon net, GF/F and GF75 filters.
