An equation is derived to express the sensitivity of daily, watercolumn production by phytoplankton in the ocean to variations in irradiance at the sea surface. Assuming no spectral effects, and a vertically uniform chlorophyll profile, the sensitivi

A round-robin comparison on in-water bio-optical algorithms. In: Remote Sensing of Environment. Vol. 162 (2015) 271-294. (DOI: 10.1016/j.rse.2013.09.016)
Satellite-derived remote-sensing reflectance (Rrs) can be used for mapping biogeochemically relevant variables, such as the chlorophyll concentration and the Inherent Optical Properties (IOPs) of the water, at global scale for use in climate-change s

Phytoplankton phenology and primary production were examined in the Iceland–Faroe region through synthesis of all available data, both in situ and remotely sensed. In the Arctic water, the early onset of stratification in spring gave rise to the ra

Remote sensing offers many advantages in the development of ecosystem indicators for the pelagic zone of the ocean. Particularly suitable in this context are the indicators arising from time series that can be constructed from remotely sensed data. F

Remote sensing provides our only window into the phytoplankton community on synoptic scales, permitting the construction of spatially distributed time series of biomass indexed as chlorophyll concentration. Data from the SeaWiFS mission have accumula

The Remote Sensing Unit (RSU) at the Bedford Institute of Oceanography (BIO) has been monitoring the North Atlantic using ocean colour products for decades. Optical sensors used include CZCS, POLDER, SeaWiFS, MODIS/Aqua and MERIS. The monitoring area

REMOTE SENSING OF ENVIRONMENT. 112(8)
A protocol is developed for calculation of phytoplankton production from remotely-sensed data in the operational mode. The key element is an objective assignment, on a pixel-by-pixel basis, of the parameters required to implement a primary production

Aging and senescence are fundamental biological processes. Their importance is not diminished by the lack of theoretical understanding. Ability to recover from small perturbations (stability) and the size of perturbations from which an organism can r

The interior stability of an isothermal shock is studied as an initial value problem for inviscid one- and two-dimensional perturbations and as an initial-boundary value problem for viscous one-dimensional perturbations. The initial steady velocity p
