The European Unions' Marine Strategy Framework Directive aims to limit anthropogenic influences in the marine environment. But ecosystems are characterized by high variability, and it is not trivial define its natural state. Here, we use physical environment as a basis for classification, determines conditions which organisms must operate survive thrive locally. We present delineation of North Sea into five distinct regimes, based on multidecadal stratification characteristics. Results 51...
Goldman, McCarthy & Peavey (1979b) argued that growth rates of phyto-plankton in apparently oligotrophic ocean waters may near maximal. Their hypothesis was succinctly restated by Goldman (1980): ‘…the chemical composition phytoplankton is extremely variable under exacting laboratory conditions nutrient limitation and approaches the ‘Redfield’ proportions (C:N:P 106:16:1) when neither nitrogen nor phosphorus limiting so maximal are attained. In marine surface particular matter often...
Abstract Tett, P., Carreira, C., Mills, D. K., van Leeuwen, S., Foden, J., Bresnan, E., and Gowen, R. J. 2008. Use of a Phytoplankton Community Index to assess the health coastal waters. – ICES Journal Marine Science, 65: 1475–1482. Monitoring marine-ecosystem status requires indicators community structure function. As structural indicator, we propose (PCI) based on abundance “life-forms” such as “pelagic diatoms” or “medium-sized autotrophic dinoflagellates”. To calculate PCI, data showing...
From work on nutrient limited algal growth an equation was derived relating chlorophyll:carbon ratio ( ccr ) to cell quota Q ). urn:x-wiley:00243590:media:lno19752040587:lno19752040587-math-0001 where r/µ ′ max is a constant representing the of specific respiration rate maximum rate, k q (apparent) subsistence quota, and third —the value Chl:C when Q/k = µ /r . This hypothesis investigated using data from spring phytoplankton increase in Loch Creran 1973. The measured as P:C atomic ratio,...
Abstract. Recent dinoflagellate cysts were collected from Scottish west coast sealoch sediments and germinated to establish cyst-theca relationships. Fourteen different Protoperidinium species have been studied using the scanning electron microscope. New relationships are described for subinerme, P. thorianum ?P. hangoei.The archeopyle of excentricum cyst is first time. The archeopyles pentagonum (Trinovantedinium capitatum) leonis (Quinquecuspis concretum) previously as representing loss...
Coastal shallow lagoons are considered to be highly important systems, which have specific biogeochemical cycles and characteristics. The assessment of sediment-water interfaces is essential understand nutrient dynamics evaluate the vulnerability eutrophication, especially in regions restricted water exchange (RRE), such as Ria Formosa, natural conditions for accumulation nutrients. Water samples were collected during years 2006 2007-08 nutrients, chlorophyll a dissolved oxygen. Sediment...
