Sampling scale sensitivities in surface ocean pCO2 reconstructions in the Southern Ocean by Djeutchouang, Laique Merlin

“…The Southern Ocean plays a pre-eminent role in the global carbon-climate system. Model studies show that since the start of the preindustrial era, the region has absorbed about 75% of excess heat and 50% of the oceanic uptake and storage (42±5 PgC) of anthropogenic CO2 emissions. …”

The geochemistry, mineralogy and igneous petrology of some fracture zone basalts from the southern Mid-Atlantic Ridge by Van Heerden, Leon

“…The compositional variation in a suite of oceanic basalts dredged from a fracture zone transecting the Mid-Atlantic Ridge at 54°S is quantitatively evaluated in terms of fractional crystallization and crystal accumulation models. Bulk rock chemistry and petrography are used to classify the samples into four distinct groups; an evolved sparsely plagioclase phyric suite (Group A), a less evolved sparsely plagioclase phyric suite (Group B), an olivine phyric suite (Group C) and a highly plagioclase phyric suite (Group D). …”

Radio observations as a tool to study shock interactions and mass ejections in novae by Nyamai, Mumbua

“…This work highlights the importance of obtaining well sampled radio light curves of novae which give more insight into the physical processes that follow nova explosions, which may have been overlooked before due to sparsely sampled radio light curves. Resolved radio images of novae are also crucial in determining the morphology of the ejecta hence provide clues on the approach to modelling radio emission from novae. …”

Predicting household poverty with machine learning methods: the case of Malawi by Chinyama, Francis

“…Therefore, this study looked at whether machinelearning models can be used on existing survey data to predict poor and non-poor households, and whether these models can predict poverty using a smaller number of features than those collected in integrated household surveys. …”

Turbulence in the sea ice impacted Southern Ocean and its implications for primary production and carbon export by Nunes, Da Costa Isabelle

“…Secondly, the challenges associated with making observations in or near sea ice and in the harsh and remote conditions of the Southern Ocean means that the region is sparsely sampled, and as such, the parameterizations of the small scale and turbulent terms in global climate models are validated based only on a few in situ samples. …”
