Distribution and abundance of european hake merluccius merluccius (l.), eggs and larvae in the north east atlantic waters in 1995 and 1998 in relation to hydrographic conditions
(Oxford University Press (OUP), 2004-04-30)Plankton samples from surveys in 1995 and 1998 were analysed in order to study the spatial distribution of hake (Merluccius merluccius) eggs and larvae. The cruises covered an extensive area from the south of the Bay of ... -
Fundamentals of in situ digital camera methodology for water quality monitoring of coast and ocean
(MDPI AG, 2009-07-22)Conventional digital cameras, the Nikon Coolpix885 (R) and the SeaLife ECOshot (R), were used as in situ optical instruments for water quality monitoring. Measured response spectra showed that these digital cameras are ... -
Is chlorophyll-athe best surrogate for organic matter enrichment in submicron primary marine aerosol?
(Wiley-Blackwell, 2013-05-27)Initial efforts toward developing a combined organic-inorganic sea spray source function parameterization for large-scale models made use of chlorophyll-a (Chl-a) and wind speed as input parameters to combine oceanic biology ... -
Molecular fingerprinting of lacustrian cyanobacterial communities: regional patterns in summer diversity
(Oxford University Press (OUP), 2013-07-17)The assessment of lacustrian water quality is necessary to comply with environmental regulations. At the regional scale, difficulties reside in the selection of representative lakes. Given the risks towards water quality ... -
Photochemical impact on ozone fluxes in coastal waters
(Hindawi Limited, 2012-01-01)Ozone fluxes, derived from gradient measurements in Northeast Atlantic coastal waters, were observed to depend on both tide height and solar radiation. Peak ozone fluxes of -0.26 +/- 0.04 mu g m(-2) s(-1) occurred during ... -
Pigment signatures reveal temporal and regional differences in taxonomic phytoplankton composition off the west coast of ireland
(Oxford University Press (OUP), 2001-08-01)The composition of phytoplankton assemblages in April, 1998 in Galway Bay and during a summer phytoplankton bloom occurring southwest of Ireland in August, 1998, was characterized by pigments measured by high-performance ... -
Scale and the plankton dynamics of the Irish Shelf and adjacent offshore waters
(2012-01-26)The patchy distribution of planktonic organisms has been known for over 100 years and ever since then attempts have been made to model this variability over a hierarchy of scales. Forcing mechanisms that act on plankton ...
