DOI: 10.1002/2016jc012162
Abstract: Understanding the physical and biogeochemical processes that control CO2 and dissolved oxygen (DO) dynamics in the Arctic Ocean (AO) is crucial for predicting future air-sea CO2 fluxes and ocean acidification. Past studies have primarily been… read more here.

DOI: 10.1002/2017jc012978
Abstract: Wave attenuation from two field experiments in the ice-covered Southern Ocean is examined. Instead of monotonically increasing with shorter waves, the measured apparent attenuation rate peaks at an intermediate wave period. This ‘rollover' phenomenon has… read more here.

DOI: 10.1002/lno.11723
Abstract: Documenting anaerobic microbial metabolisms in hypersaline perennially ice‐covered lakes in Antarctica further refines the environmental limits to life and may reveal rare biogeochemical mechanisms and/or novel microbial catalysts of elemental cycling. We assessed rates of… read more here.
