gauge_p

latitude in degrees: -90 to 90, standard: 0

atmospheric pressure in bar, standard: 1 atm (at sea level)

PUBLIC function: calculates the gauge pressure (total pressure minus atmospheric pressure) from the depth (in m) and the latitude (in degrees: -90 to 90) and the atmospheric pressure (in bar)

AquaEnv is an integrated development toolbox for aquatic
        chemical model generation focused on (ocean) acidification and
        CO2 air-water exchange. It contains all elements necessary to
        model the pH, the related CO2 air-water exchange, as well as
        aquatic acid-base chemistry in general for an arbitrary marine,
        estuarine or freshwater system. Also chemical batches can be
        modelled. Next to the routines necessary to calculate desired
        information, AquaEnv also contains a suite of tools to
        visualize this information. Furthermore, AquaEnv can not only
        be used to build dynamic models of aquatic systems, but it can
        also serve as a simple desktop tool for the experimental
        aquatic chemist to generate and visualize all possible derived
        information from a set of measurements with one single easy to
        use R function. Additionally, the sensitivity of the system to
        variations in the input variables can be visualized. The
        corresponding publication in Aquatic Geochemistry can be found
