Biological effects of contaminants: Quantification of δ-aminolevulinic acid dehydratase (ALA-D) activity in fish blood.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2004)
This document describes a colorimetric method to quantify the enzyme δ-aminolevulinic acid
dehydratase (ALA-D) in fish blood. ALA-D is an enzyme in the heme synthesis pathway. The
activity of the enzyme is inhibited by ...
Biological effects of contaminants: Radioimmunoassay (RIA) and enzyme-linked immunosorbent assay (ELISA) techniques for the measurement of marine fish vitellogenins.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2002)
This document describes immunochemical methods to quantify the egg-yolk precursor protein vitellogenin in fish plasma. Vitellogenin is normally produced by the liver of mature female fish in response to 17β-oestradiol (E2) ...
Biological effects of contaminants: measurement of scope for growth in mussels.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2006)
Scope for growth (SFG) is a method of assessing the whole-animal physiological response to
sublethal stress induced by pollutants. It has been applied widely in small- and large-scale
pollution monitoring programmes in ...
Soft-bottom macrofauna: collection, treatment, and quality assurance of samples.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2009)
These recommendations are intended to standardize the methods for benthos surveys used by different scientists to increase the comparability of results for different areas.
The results of ICES/HELCOM Quality Assurance ...
Chlorophyll a: Determination by spectroscopic methods.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2001)
Chlorophyll a is the principal pigment in plants. As a biomass indicator of aquatic microalgae which support food webs in the sea, it is probably the most frequently measured biochemical parameter in oceanography.
This ...
Biological effects of contaminants: Corophium sp. sediment bioassay and toxicity test.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2001)
The method described here is a whole-sediment reworker bioassay using burrowing amphipods. This method description covers the use of Corophium spp., as this is the genus most commonly used in Europe, but the procedure can ...
Biological effects of contaminants: Sediment bioassay using the polychaete Arenicola marina.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2001)
The method described here is a whole-sediment reworker bioassay using the polychaete Arenicola marina, a direct deposit feeder that is widely distributed in European coastal waters and on the east coast of North America. ...
Biological monitoring: General guidelines for quality assurance.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2004)
These guidelines have been prepared by the ICES/OSPAR Steering Group on Quality Assurance of Biological Measurements in the Northeast Atlantic (SGQAE), as part of its role to encourage the production of biological data of ...
ICES Guidelines for XBT data. (Compiled January 2000; revised August 2001; April 2006)
(International Council for the Exploration of the Sea (ICES), Copehagen, Denmark, 2006)
The Expendable Bathythermograph (XBT) has been used by oceanographers for many years to
obtain information on the temperature structure of the ocean to depths of up to
1500 meters. The
XBT probe is typically launched ...
ICES Guidelines for CTD data. (Compiled March 2000; revised August 2001; June 2006)
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2006)
CTD (conductivity, temperature and depth) instruments were introduced to the
oceanography
community in the late 1960's. Since then, the electronic measurement of
conduct
ivity,
temperature and pressure provided by ...
