Microbial biodiversity in the southern Indian Ocean and Southern Ocean
… to perform basin wide physical and chemical oceanographic assessments in tandem with microbiological screening with the majority of studies only looking at a single component of the microbial community. In this study the full microbial diversity, from viruses to protists, was characterised …

Ocean model diagnosis of variability in the South Indian Ocean
… (SST) variability in the South Indian Ocean may significantly influence weather and climate patterns in the southern African region. SST, in tum, can be influenced by variability in ocean fluxes, observations of which are limited in the South Indian Ocean and it is necessary to augment them …

The Strangelove Ocean
… and its far-reaching consequences. “Strangelove ocean” is a scientific term used to refer to the post-Permian extinction landscape—a desolate ocean in which over 95% of marine species perished. The only species that survived lurked deep under the decay and debris, evolving and resurfacing …

Ocean of Objects
… ending up in landfills. The installation work, Ocean of Objects, arranges mundane objects in a different context within a diorama. The United States is in an age of consumerism where our relationship to the objects we buy defines the way we conceptualize our relationship to the physical …

Cloud effects on ocean mixed layer in the northeast Pacific Ocean.
… to examine the effects of clouds on the ocean mixed layer, both short-term and seasonal. It utilized data collected at Ocean Station Papa in the northeast Pacific. Two numerical modeling simulations were performed (i.e., with variable cloud and with variable precipitation). The results …

Sampling scale sensitivities in surface ocean pCO2 reconstructions in the Southern Ocean
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. However, due to …

Upper ocean variability and tropical cyclones in the South West Indian Ocean
… (BLT). Similar to cyclones in other tropical ocean basins, tropical cyclones in the South West Indian Ocean also cause significant social and economic damage in southeastern Africa and Madagascar. To forecast TC intensity more accurately, monitoring upper ocean conditions in the South Indian …

Ocean bottom seismic scattering
Seismic studies of the oceanic crust, both experimental and theoretical, often assume a flat seafloor and laterally homogeneous crust. This is done regardless of the appearance in seismic data of obvious effects due to scattering from lateral heterogeneities both on and in the seafloor. Detailed …

Data-driven Ocean Modelling
… and assessing data-driven models of the ocean. Specifically we develop data-driven emulators of an idealised configuration of a physics-based ocean simulator, MITgcm. While work focuses on idealised cases, these simplified configurations nevertheless capture important aspects of the …

Models for ocean waves
Ocean waves represent an important design factor in many coastal engineering applications. Although extreme wave height is usually considered the single most important of these factors there are other important aspects that require consideration. These include the probability distribution of wave …

Mixing by ocean eddies
… as heat and potential vorticity laterally in the ocean. While this transport plays an important role in the climate system, especially in the Southern Ocean, we lack a, comprehensive understanding of what sets mixing rates. This thesis seeks to advance this understanding through three related …

Scale closure in upper ocean optical properties : from single particles to ocean color
… of chlorophyll concentration from satellite ocean color are an indicator of phytoplankton primary productivity, with implications for foodweb structure, fisheries, and the global carbon cycle. Current models describing the relationship between optical properties and chlorophyll do not account …

The refractive effects of laser propagation through the ocean and within the ocean
This thesis investigates the effect of the ocean water attenuation on a laser beam fired upward inside the ocean. The laser beam spreading due to scattering is approximated. The method used is a computer Monte Carlo simulation. Angular spreading of light caused by refraction at the sea surface is …

Ice - ocean - atmosphere interactions in the Southern Ocean and implications for phytoplankton phenology
… advance and retreat of sea ice in the Southern Ocean is recognised as one of the largest seasonal events on Earth. Such considerable physical changes have profound effects on the vertical structure of the water column, and hence controls the availability of both light and nutrients to …

The structure of the upper ocean, atmosphere and heat fluxes - Tropical Indian Ocean
Sea surface temperatures in the tropical Indian Ocean have been shown to be inversely related to South African summer rainfall, making advanced predictions of this rainfall practicable. Such predictability has enormous potential economic benefits. However, these predictions have been purely …
