“…In contrast, Kr and Xe are more soluble with a strong solubility dependence on temperature (Wood and Caputi, 1966;Weiss and Kyser, 1978), and thus Kr and Xe respond primarily to diffusive gas exchange.…”

“…The diffusivities differ by a factor of five with helium being the most diffusive (Jähne et al, 1987). The solubilities differ by a factor of ten, with xenon being the most soluble (Wood and Caputi, 1966;Weiss, 1971;Weiss and Kyser, 1978;Hamme and Emerson, 2004b). Additionally, the solubilities of the heavier noble gases have a stronger dependence on temperature.…”

“…The solubilities vary by an order of magnitude, with Xe being the most soluble and having the strongest temperature dependence. Solubility values for He are from a modified version of Weiss (1971), Ne and Ar solubilities are from Hamme and Emerson (2004b), Kr solubility is from Weiss and Kyser (1978) and Xe solubility is from Wood and Caputi (1966). In previous seawater studies, Ar has been used in conjunction with O 2 to estimate biological production (Craig and Hayward, 1987;Spitzer and Jenkins, 1989).…”

“…Positive (negative) saturation anomalies reflect that the gas is supersaturated (undersaturated), and the magnitude of the saturation anomalies corresponds to the magnitude of the departure from equilibrium. The solubilities of many of the noble gases were determined by Weiss in the 1970s (Weiss, 1970(Weiss, , 1971Weiss and Kyser, 1978 Weiss and Kyser (1978) and for Xe, the solubility value determined by Wood and Caputi (1966). We propagated the uncertainty in solubility determination throughout all the calculations.…”

The five noble gases (helium, neon, argon, krypton, and xenon) are biologically and chemically inert, making them ideal oceanographic tracers. Additionally, the noble gases have a wide range of solubilities and molecular diffusivities, and thus respond differently to physical forcing. Tritium, an isotope of hydrogen, is useful in tandem with its daughter helium-3 as a tracer for water mass ages. In this thesis, a fourteen month time-series of the five noble gases, helium-3 and tritium was measured at the Bermuda Atlantic Time-series Study (BATS) site. The time-series of five noble gases was used to develop a parameterization of air-sea gas exchange for oligotrophic waters and wind speeds between 0 and 13 m s −1 that explicitly includes bubble processes and that constrains diffusive gas exchange to ± 6% and complete and partial air injection processes to ± 15%. Additionally, the parameterization is based on weeks to seasonal time scales, matching the time scales of many relevant biogeochemical cycles. The time-series of helium isotopes, tritium, argon, and oxygen was used to constrain upper ocean biological production. Specifically, the helium flux gauge technique was used to estimate new production, apparent oxygen utilization rates were used to quantify export production, and euphotic zone seasonal cycles of oxygen and argon were used to determine net community production. The concurrent use of these three methods allows examination of the relationship between the types of production and begins to address a number of apparent inconsistencies in the elemental budgets of carbon, oxygen, and nitrogen.

Estimating the recharge properties of the deep ocean using noble gases and helium isotopes

et al. 2016

The distribution of noble gases and helium isotopes in the dense shelf waters of Antarctica reflects the boundary conditions near the ocean surface: air‐sea exchange, sea ice formation, and subsurface ice melt. We use a nonlinear least squares solution to determine the value of the recharge temperature and salinity, as well as the excess air injection and glacial meltwater content throughout the water column and in the precursor to Antarctic Bottom Water. The noble gas‐derived recharge temperature and salinity in the Weddell Gyre are −1.95°C and 34.95 psu near 5500 m; these cold, salty recharge values are a result of surface cooling as well as brine rejection during sea ice formation in Antarctic polynyas. In comparison, the global value for deep water recharge temperature is −0.44°C at 5500 m, which is 1.5°C warmer than the southern hemisphere deep water recharge temperature, reflecting a distinct contribution from the north Atlantic. The contrast between northern and southern hemisphere recharge properties highlights the impact of sea ice formation on setting the gas properties in southern sourced deep water. Below 1000 m, glacial meltwater averages 3.5‰ by volume and represents greater than 50% of the excess neon and argon found in the water column. These results indicate glacial melt has a nonnegligible impact on the atmospheric gas content of Antarctic Bottom Water.
