Depth, salinity, temperature, and pH collected from CTD profiler equipped with a pH sensor and Niskin bottles from two stations in the northern end of Hood Canal in Puget Sound, Washington during the day and night from 2012-04-09 to 2012-06-16 (NCEI Accession 0259306)

This dataset contains the discrete bottle (CTD profile) data of the pH environment experienced by Euphausia pacifica eggs and larvae at two station the northern end of Hood Canal in Puget Sound, Washington. The southwest station, P14, is deeper (180 m) than the northeastern station, P15 (130 m). Samples were collected during the day and night on 9−10 April and 15−16 June 2012. Physical and chemical data were collected using a CTD profiler equipped with a pH sensor (SBE 18, Sea-Bird Electronics) and Niskin bottles. This design was chosen to sample during the spawning season of E. pacifica (approximately February to July) in an area where low pH waters occur.
