Un-mixing the Ocean: Double Diffusion and Turbulence in Polar Oceans
… and observations of double-diffusion in polar settings. Double diffusion refers to processes occurring due to the difference in molecular diffusivities between two components that both contribute to the density. Specifically, these processes occur in the ocean due to the much slower …

High-Resolution In Situ Oxygen-Argon Studies of Surface Biological and Physical Processes in the Polar Oceans
… and autonomous O2 measurements in the global oceans.</p>

Air-Sea CO2 Exchange and Carbon Dynamics in Foxe Basin: Findings from a 2023 Oceanographic Survey
… This process is particularly important in polar oceans, where sea-ice formation releases brine to the water column below and can create dense waters that sink and sequester dissolved carbon into deep waters. Foxe Basin, an inland sea north of Hudson Bay between Baffin Island and Melville …

Hemmung der Eisrekristallisation in wässrigen Lösungen durch Antigefrierglykopeptide
… (AFGP), which are present in some fish of the polar oceans. Therefore, within the present work several substances were investigated that inhibit the ice growth similar to AFP and AFGP. The efficiency of this growth inhibition was determined using a special form of Ostwald ripening, namely, the …

The convective desalination of sea ice
… processes affecting the growth of sea ice in the polar oceans in order to improve climate models. Newly formed sea ice contains a significant amount of salt as liquid brine in the interstices of an ice matrix. My focus is on one of the processes by which the salt content of sea ice decreases, …

The meridional and seasonal variability of the carbonate system in the Southeast Atlantic sector of the Southern Ocean: SCALE 2019 Experiment
… pH and carbonate data, distant areas like polar oceans remain seasonally undersampled. Consequently, there may be a significant gap in our understanding of biological implications of future ocean acidification (OA). This study seeks to examine the seawater state conditions of the carbonate …

Early life-history ecology of Arctic benthic invertebrates
… laboratory for studying change. In addition, the polar oceans are a severe, cold habitat with extreme seasonality in light and food availability. Thus, directly studying the organisms in this region rather than extrapolating based on patterns at lower latitudes is imperative. My primary objective …

Body Size In Antarctic And Temperate Sea Spiders: The Role Of Temperature And Oxygen
… or tropical regions, a phenomenon known as polar gigantism. While there are many potential explanations for why these animals reach such large sizes, the hypothesis that has received the most attention is the oxygen-temperature hypothesis (OTH). This hypothesis posits that polar gigantism …

Physiological and metabolic characteristics of polar diatoms: insights into cold adaptation and potential for biotechnology
The polar regions represent two of the most extreme environments on Earth, with sub-zero temperatures, sustained light in the summer and complete darkness in the winter. Marine diatoms are prevalent in the polar oceans, significantly contributing to primary productivity and ecosystem functioning. …

Southern Ocean Centennial Oscillations in the CMIP6 Ensemble
… such as the strength of the Antarctic Circumpolar Current, meridional overturning circulations, and deep ocean heat content, even in the presence of steady climate forcing. This thesis explores the dynamics behind these oscillations, how these vary across different climate models, and how …
