Diagnosis of physical and biological controls on phytoplankton distribution in the Gulf of Maine-Georges Bank region
… the effect of the circulation field on the distribution of phytoplankton, and the relative importance of physical circulation and biological sources by using a data assimilation approach. The model results reveal seasonal and geographic variations of phytoplankton concentration, which …

Variación anual de la abundancia de bacterias y de la contribución del nano y picofitoplancton a la producción fitoplanctónica total en el Golfo de Cádiz
Chlorophyll and phytoplankton distribution and concentration were studied during 2014 and 2015 in the Gulf of Cádiz. The highest chlorophyll concentrations are found at coastal stations in spring during both years. Pico and nanophytoplankton are the main contributor to total chlorophyll, with …

Estimating the spatial and temporal variability of primary production from a combination of in situ and remote sensing data a southern Benguela case study
… data containing subsurface temperature and phytoplankton distribution profiles. Each profile is associated in time and space with satellite remotely-sensed wind, sea surface temperature and surface chlorophyll a data. The bottom depth, season and location of each profile are also recorded. …

Utilising Chlorophyll Fluorescence to Assess the Variability of Phytoplankton Biomass and Productivity in the North-West European Shelf Seas
Marine primary productivity by phytoplankton drives the conversion of CO2 into organic carbon, thus supporting key marine ecosystem services such as biogeochemical nutrient cycles and fisheries. Therefore, the ability to accurately quantify and predict the environmental influences that govern this …

Quantifying spatial and temporal scales of phytoplankton variability in the Sub-Antarctic Ocean using a high-resolution glider dataset
Phytoplankton in the Sub-Antarctic Southern 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 …

Environmental drivers and advective transport of harmful phytoplankton in North West European shelf seas
Harmful phytoplankton occur naturally in British waters. However, little is known about the environmental drivers that lead to the formation and advection of harmful algae blooms (HABs). To minimise adverse effects of HABs it is necessary to improve our understanding of links between advection, …

Qualitative and quantitative analyses of Lake Baikal's surface-waters using ocean colour satellite data (SeaWiFS)
One of the most difficult issues when dealing with optical water remote-sensing is its acceptance as a useful application for environmental research. This problem is, on the one hand, concerned with the optical complexity and variability of the investigated natural media, and therefore the question …
