Title: PH measured in situ over depth in the kelp forest (36° 37.3’ N, 121° 54.1’ W) recorded in July 2018 (NCEI Accession 0278151)
Abstract: This dataset contains chemical data collected on Mooring - Hopkins Marine Stations during deployment KELP from 2018-07-11 to 2018-07-20. These data include pH. The instruments used to collect these data include pH Sensor. These data were collected by Kerry J. Nickols of California State University Northridge, Yuichiro Takeshita of Monterey Bay Aquarium Research Institute, David Mucciarone, Heidi Hirsh, Robert B. Dunbar, and Stephen G. Monismith of Stanford University, and Sarah Traiger of United States Geological Survey as part of the "Collaborative Research: RUI: Building a mechanistic understanding of water column chemistry alteration by kelp forests: emerging contributions of foundation species (Kelp forest biogeochemistry)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-10-16.

Supplementary information: Acquisition Description:
Continuous flow pumping experiments were conducted inside the kelp forest from a vessel within 15-m of the kelp mooring to obtain high temporal and vertical resolution biogeochemical data. Two experiments were conducted (July 11-13 and July 18-20, 2018) that overlapped with the kelp mooring pH timeseries data.

Seawater was pumped from five depths spanning the water column using five sections of equal-length polypropylene tubing (3/8” ID, 1/2” OD) deployed over the side of a moored vessel. The depths presented here include the surface (valve #5), 6 mab (2-5 mbs, valve #3), and 1 mab (7-10 mbs, valve #1). A custom auto sampling manifold introduced water from each of the 5 tubes to a continuous flow system at 5-minute intervals, allowing the full suite of depths to be sampled every 25 minutes for the duration of each experiment (similar to Koweek et al., 2015a; Koweek et al., 2015b; Teneva et al., 2013). Seawater was drawn into the continuous flow system from each depth by a peristaltic pump operating at 2L/min. The continuous flow system included a DuraFET pH sensor measuring pH at 20 samples per min .
