Vertical transport at curved ocean fronts
Ocean fronts are boundaries that separate distinct water masses and span a broad range of spatial scales, from basin-scale (103 km) western boundary currents such as the Gulf Stream and Kuroshio, to mesoscale (102 km) eddies and submesoscale (10 km) filaments. At mesoscale and submesoscale fronts, …

Ocean fronts formed at sea ice boundaries
… sea ice forms a buoyancy source for the upper ocean which creates a strong density gradient in both horizontal and vertical directions. If, in particular, the ocean density front is formed in the Bering sea during winter, the frontal dynamics are influenced by local shelf/slope processes. …

The evolution of ocean fronts in the presence of mixed layer turbulence
Fronts, or regions with large horizontal density gradients, are common and important features of the upper ocean. On sufficiently large scales, the hydrostatic pressure gradient associated with the horizontal density gradient is often nearly balanced by a geostrophic (or thermal wind) …

Machine Learning Models for On-Orbit Detection of Temperature and Chlorophyll Ocean Fronts
Small-scale ocean fronts play a significant role in absorbing the excess heat and CO2 generated by climate change, yet their dynamics are not well understood. Existing in-situ and remote sensing measurements of the ocean are of inadequate spatial and temporal coverage to globally map small-scale …

Statistical modelling and variability of the subtropical front, New Zealand
Ocean fronts are narrow zones of intense dynamic activity that play an important role in global ocean-atmosphere interactions. Of particular significance is the circumglobal frontal system of the Southern Ocean where intermediate water masses are formed, heat, salt, nutrients and momentum are …

Climate change impact on ecosystems of Prince Edward Islands: role of oceanic mesoscale processes
… respond to a changing climate in the Southern Ocean. Recent studies have proposed that climate changes reported at the islands may correspond in time to a southward shift of the ACC and in particular of the SAF. This southward migration in the geographic position of major ocean fronts is likely …

Characteristics of Nitrogen- and Iron-Limited Growth in the Diatom Phaeodactylum tricornutum, and in Natural Phytoplankton Populations.
… Phaeodactylum tricomutum), and in the open ocean (e.g. Jellicoe Channel and the Subtropical Convergence Zone, New Zealand). Although the characteristics of ammonium uptake have been extensively studied in marine phytoplankton, comparatively little information exists on rates of assimilation. …

The foraging ecology of the short-tailed shearwater puffinus tenuirostris.
… with elevated chlorophyll a associated with ocean fronts, where search effort was increased. How adults allocated time and energy during the entire chick-rearing period was investigated via the simultaneous assessment of adult attendance, adult mass change, the rate of energy delivery to …
