Trichromatic colour vision, characterized by three retinal photopigments tuned to peak
wavelengths of∼ 430 nm,∼ 535 nm and∼ 562 nm (refs,), has evolved convergently in …

Phytoplankton size structure is acknowledged as a fundamental property determining
energy flow through 'microbial'or 'herbivore'pathways. The balance between these two …

Vertical exchange between deep, nutrient‐rich and nutrient‐depleted surface waters
controls the physical supply of nutrients into the euphotic zone in the oligotrophic waters of …

Two food web models, a single‐species and a multispecies formulation, are incorporated
into a three‐dimensional eddy‐resolving model of an unstable frontal jet to investigate the …

Estimating vertical velocity in the oceanic upper layers is a key issue for understanding
ocean dynamics and the transport of biogeochemical elements. This paper aims to identify …

This paper presents a detailed diagnostic analysis of hydrographic and current meter data
from three, rapidly repeated, fine-scale surveys of the Almeria–Oran front. Instability of the …

Using data from high-resolution surveys of the Iceland-Færœs Front, the authors have
calculated synoptic maps of the geostrophic velocity, vorticity, and potential vorticity on …

Previous observational and modelling studies of open ocean frontal regions have found
large vertical velocities associated with instabilities on the frontal jet. A combined …

Estimation of vertical velocity is a key issue for understanding ocean physics and transport of
biogeochemical tracers. We examine the accuracy of estimating vertical velocity in fronts …

The results of high‐resolution biogeochemical measurements in the upper 200 m of the
Ross Sea, Antarctica, obtained during the AESOPS (US JGOFS) program using the Lamont …
