Drivers of short-term variability in phytoplankton production in an embayment of the southern Benguela upwelling system: an observational and modelling study by Burger, Jessica

“…In addition to supporting 40-50% of total SBUS productivity, SHB often experiences harmful algal blooms (HABs) and hypoxic conditions that are difficult to predict given the high sub-seasonal variability that characterises this region. To better understand this variability, net primary production (NPP), nitrate and ammonium uptake, and phytoplankton community composition were measured for ten days during the upwelling season at an anchor station in SHB. …”

An observational study to assess coagulation abnormalities in patients with elevated levels of urea and/or creatinine secondary to renal failure, presenting for renal biopsy – chal... by Rodrigues, Jacques

“…Conclusion TEG® and ROTEM® provides a global assessment of coagulation and might be helpful in assessing coagulation defects in patients with elevated levels of urea and/or creatinine presenting for a renal biopsy, with possible extension to the surgical patient with abnormal renal function presenting for a surgical procedure to assess their risk of bleeding, especially in those who are being considered for a regional or neuraxial technique - as this could be an unacceptable risk in this population sub-group .…”

Simulating the Characteristics and Influences of the Botswana High over Southern Africa using the Model for Prediction Across Scales (MPAS) by Maoyi, Molulaqhooa Linda

“…Given this, the results of this thesis suggest that the Botswana High might be a conduit pipe through which ENSO signals influence DM1 over the region. Investigation into the impact of ENSO on the Botswana High reveals that the absence of ENSO forcing reduces the amplitude of the Botswana High variability, but the signal of the variability remains. …”

Surface and sub-surface hydrographic variability at the Prince Edward Islands: perspectives from the high resolution GLORYS model by Soares, Bianca

“…Additionally, GLORYS was also able to simulate all five water masses, known to occur within the PEI region, throughout time. When GLORYS was compared to single point in situ SST time series data, a seasonal bias was observed with GLORYS overestimating SST in late summer (January to March) and underestimating SST for the remainder of the year (May to December). …”
