Corrections are then made for the lost noble gas in the water, using precisely measured mass and volume. The method uses 6-liter stainless steel flasks with Nupro valves for improved leak-tightness. This extraction technique made it possible to measure neon as well as the heavier noble-gas isotopes, all from the same sample, providing a constraint on \"excess air\" using the neon. Field campaigns sampling groundwater were conducted in Oregon and Arizona. Data from these campaigns are deposited here.\n\ncdm_data_type = Other\nVARIABLES:\nState_ID (unitless)\nLocation (unitless)\nSite (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nElevation_m (meters (m))\nElevation_ft (feet (ft))\nPressure_atm (atmosphere (atm))\nMid_screen_depth_ft (feet (ft))\nScreen_length_ft (feet (ft))\nDepth_to_water_ft (feet (ft))\nSampling_date (unitless)\nNG_method (unitless)\nHe (cubic centimeters per gram (cc/g))\nHe_err (cubic centimeters per gram (cc/g))\nNe (cubic centimeters per gram (cc/g))\nNe_err (cubic centimeters per gram (cc/g))\nAr (cubic centimeters per gram (cc/g))\nAr_err (cubic centimeters per gram (cc/g))\nKr (cubic centimeters per gram (cc/g))\n...

See \"Related Datasets\" section for alkalinity data. Discrete samples were collected at intervals of salinity along each estuary. An underway measurements system was also operated during each transect. Discrete samples were analyzed via a number of methods described below. Underway measurements were collected using the procedures described in Hunt et al. (2013).\n\nOrganic alkalinity is a poorly understood component of the estuarine and coastal ocean acid-base system. This lack of understanding makes assessment of ocean acidification vulnerability and inorganic carbon dynamics more difficult. However, the methods used to quantify organic alkalinity and its effects on the acid-base system are not standardized. In this work we examined several approaches for the measurement of organic alkalinity, and their application to inorganic carbon dynamics.\n\ncdm_data_type = Other\nVARIABLES:\nyear (unitless)\nmonth (unitless)\nday (unitless)\nhour (unitless)\nminute (unitless)\nsecond (unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nJulian_Day (unitless)\nsecDay (sssss)\nlat (degrees_north)\nlongitude (degrees_east)\nheading (degrees)\nspeed (meters per second (m/s))\nWt (degreesC)\ncond (millimho per centimeter (mmho/cm))\n...
