Observational data and model output for sediment nutrient cycling at Patagonian fjords

Hong Chin Ng, Jon R. Hawkings, Jemma L. Wadham, Katharine R. Hendry, Tim M. Conway, Sebastien Bertrand, Matthias Sieber, Brent A. Summers, Felipe S. Freitas, James P.J. Ward, Helena V. Pryer & Sandra Arndt
Glacier meltwater supplies a significant amount of silicon (Si) and iron (Fe) sourced from weathered bedrock to downstream ecosystems. However, the extent to which these essential nutrients reach the ocean is regulated by the nature of the benthic cycling of dissolved Si and Fe within fjord systems, given the rapid deposition of reactive particulate fractions at fjord heads. The dataset is used to examine the benthic cycling of the two nutrients at Patagonian fjord heads...

Fields and parameters related to the flow of ice in the Antarctic Ice Sheet recovered using inverse methods and satellite data

Robert Arthern, Rosie Williams, Richard Hindmarsh & Hamish Pritchard
We can learn about the flow of ice in Antarctica by evaluating the key parameters that control the flow speed. These parameters include the basal drag coefficient and the ice viscosity. They can be estimated by adjusting their values so that model velocities at the upper surface agree with satellite observations. This dataset was produced using inverse methods to obtain the parameter values. In this approach a cost function that describes the mismatch between model...

Electron Diffusion by Magnetosonic Waves in the Earth's Radiation Belts

Jin-Mann Wong
We conduct a global survey of magnetosonic waves and compute the associated bounce and drift averaged diffusion coefficients, taking into account co-located measurements of fpe/fce, to assess the role of magnetosonic waves in radiation belt dynamics, where fpe is the plasma frequency and fce is the electron gyrofrequency.. The average magnetosonic wave intensities increase with increasing geomagnetic activity and decreasing relative frequency with the majority of the wave power in the range fcp < f...

UCL CPOM CryoSat2 derived Dynamic Ocean Topography 2011-2021

Harold Heorton
The ocean surface height is constantly varying under the effects of gravity, density and the Earth's rotation. Information on the Ocean surface elevation in polar regions is available from the CryoSat2 Radar instrument. We compare ocean surface elevation to a static geoid product (GOCO03s) to give the part of the ocean surface elevation accountable due to surface currents, the Dynamic Ocean Topography (DOT). This measurement is smoothed over 100 km and gives monthly surface currents....
