    • Multiple stressor effects of ocean acidification and hypoxia on behavior, physiology, and gene expression of temperate reef fishes

    Metadata Updated: May 24, 2025

    The Trinidad Head Line (THL) is a transect of stations extending due west from Trinidad Head (41° 3.5¿ N) The THL was initially established in late 2006 to provide ship-based observations of hydrographic structure and the planktonic ecosystem in coastal waters off northern California. Since 2008, sampling has been conducted approximately monthly. Sampling is conducted at up to six stations along the transect, three of which are over the shelf and three over the upper slope. Data collected include hydrographic casts at each station, which measure temperature, salinity, and a suite of ancillary parameters. Physical samples collected include water samples for asssay of nutrient and chlorophyll concentrations, and net tows for zooplankton.

    Lineage Samples are collected at sea and returned to the laboratory. Hydrographic data from vertical casts are processed following practices developed by instrument manufacturer (SeaBird Electronics) to produce data at 1 m vertical resolution. Zooplankton samples are processed under magnification by researchers to enumerate target taxa by species, and where appropriate, life history stage, sex, and size.
