Trojan horses in the marine realm: characterizing protistan parasite ecology in coastal waters
… subunit ribosomal RNA molecular signatures have highlighted the fact that parasites belonging to the marine alveolate order Syndiniales are both abundant and ubiquitous in coastal and open ocean environments, suggesting a major role for this taxon in marine food webs. Two coastal sites, Saanich …

Advances in measurements of particle cycling and fluxes in the ocean
… and fluxes in this region are not due to undersampling by traps. To assess regional variability of particle export, surface and water-column measurements of 234Th were combined for the first time to measure fluxes on ~20 km scales. Attempts to relate surface properties to particle export were …

Advances in measurements of particle cycling and fluxes in the ocean
… and fluxes in this region are not due to undersampling by traps. To assess regional variability of particle export, surface and water-column measurements of ²³⁴Th were combined for the first time to measure fluxes on ~20 km scales. Attempts to relate surface properties to particle export were …

Fine-scale ecological dynamics of closely related marine microbes
… dynamics at bulk scales and with low genetic resolution. Thus, little is known about the effects of finer structure. In this thesis, I show that characterizing the dynamics of environmental microbes with finer spatiotemporal and genetic resolution reveals otherwise concealed dynamics. I use …

Late Quaternary fire histories in the eastern Mediterranean region from lake sedimentary micro-charcoals
… was developed and applied alongside a contiguous high resolution sampling strategy. Using this approach, fire activity was reconstructed based on cores from each of the sites and these data were compared with existing multi-proxy data (stable oxygen isotopes, pollen and archaeological data). …

Quantifying spatial and temporal scales of phytoplankton variability in the Sub-Antarctic Ocean using a high-resolution glider dataset
… Ocean have a distinct seasonal cycle, which is highly variable in both space and time. The seasonal and spatial distribution of chlorophyll can be attributed to the complex nature of the physical and biogeochemical factors controlling phytoplankton production. Studies show that high-resolution …

Microfaunal investigation of the Early Toarcian (Lower Jurassic) extinction event in N.W. Europe
… period of mass extinction of the marine fauna. High resolution sampling and study of the microfaunast hrough sequencesin N. W. Europe confirm that benthic foraminiferal. faunas were similarly affected by an early Toarcianfalciferum Zone event. Samples were analysed from Pliensbachian - Toarcian …

Exploring the Spatial Distribution of Marine Nitrogen Fixation Through Statistical Modeling, High-Resolution Observations and Molecular Level Characterization
… of approaches including statistical modeling, high-resolution field measurements, and gene sequencing to characterize the biogeography of marine diazotrophy.</p><p>The first approach was to model marine N2 fixation and diazotrophs using machine learning methods. To that end, I conducted …

Gelatinous zooplankton dynamics in Bantry Bay and the development of a harmful jellyfish forecast for the salmon aquaculture industry
… Muggiaea atlantica, which has been implicated in high mortality events of farmed salmon, and investigate the ecology of gelatinous zooplankton in detail. A literature review was carried out to determine the scope and applications of modelling jellyfish. The models identified could be broadly …
