Shimada (USGS field activity 2018-663-FA). CTD (Conductivity Temperature Depth) data were also collected at each depth that a Niskin-bottle sample was collected and are presented along with the water sample data. This data release supersedes version 2.0, published in September 2021 at https://doi.org/10.5066/P99DIQZ5. Versioning details are documented in the accompanying VersionHistory_P99MJ096.txt file. Purpose: These data were collected as part of the on-going Expanding Pacific Research and Exploration of Submerged Systems (EXPRESS) project, a multi-year, multi-institution cooperative research campaign in deep sea areas of California, Oregon, and Washington, including the continental shelf and slope. EXPRESS data and information are intended to guide wise use of living marine resources and habitats, inform ocean energy and mineral resource decisions, and improve offshore hazard assessments. The ultimate goal of EXPRESS is to develop comprehensive digital elevation models, habitat maps, and geologic maps, which are needed to address important issues associated with marine spatial planning, ecosystem assessments, geohazards, and the impact on sensitive ecosystems of offshore infrastructure development. This particular NOAA cruise focused on deep-sea corals, sponges, and associated habitats.

Simultaneous conductivity, salinity, and depth (CTD) data were collected with a SeaBird SBE-9 CTD profiler at each Niskin bottle sample depth. The latitude and longitude were updated in v2.0 to correct values from v1.0. Process_Date: 20181108 Process_Step: Process_Description: Seawater samples were analyzed by several different labs (see Sources) for different variables. Data from all seawater lab analyses were combined into a single document. Calcite and aragonite saturation states were calculated using an Excel Workbook Macro translation of the original CO2SYS program (Lewis and Wallace, 1998; Pierrot and others, 2006). -9999 cell value indicates no data (for example, where water was not sampled, or a water sample was not analyzed for a particular variable).

For the revision, an attribute column header in the water-column environmental variable data file (SH-18-12_BTL_CTD_v.2.0_data.csv) was revised to accurately report ammonium not ammonia. No data values were changed, nor were any changes made in the accompanying CTD data (SH-18-12_raw_CTD.zip). Metadata files for both data files were revised to reflect the new doi number, URLs, download links, and PIDs.
