National Marine Biological Analytical Quality Control Scheme
(NMBAQC)
The
Marine Environment Monitoring Group (MEMG),
formally known as the Marine Pollution Monitoring Management Group
(MPMMG) up until 1st June 2003, has been tackling the problem of
variability in methods and the quality standards achieved under
different parts of the National Marine Monitoring Programme (NMMP),
through the establishment of three quality control schemes covering
chemical, biological and ecotoxicology issues. These schemes
develop and monitor quality assurance and quality control
procedures for participating laboratories to provide comparable and
reliable data to the NMMP.
JNCC and the conservation agencies (CCW, EHS, SNH, English
Nature) participate in the National Marine Biological Analytical
Quality Control Scheme (
NMBAQC) with JNCC
representing the UK conservation agencies (CCW, EHS, SNH, English
Nature) on the NMBAQC steering committee.
The NMBAQC Scheme was established to monitor marine biological
data quality standards for benthic faunal studies. A series
of exercises is undertaken throughout the year where participating
laboratories receive samples for analysis from the scheme at
approximately three-monthly intervals. Samples distributed include
grab samples for macro benthic analysis, sets of fauna for
identification (Ring Test) and sediment samples for particle size
analysis. Laboratories also submit samples from their own
activities for re-examination (Own Samples) and also from their own
work for re-examination (Laboratory Reference).
To date the NMBAQC has focused on the identification of
infaunal species. However, due to the increasing requirement to
monitor marine habitats and species through the
EC
Habitats Directive and the
EU Water Framework Directive, there is a growing
need to establish similar quality control standards for epibiota
identification. With JNCC's past experience in epibiota field
recording and its current role in establishing
Common
Standards for Monitoring marine Special Areas of Conservation
(SAC's), the NMBAQC asked JNCC to take the lead with a pilot study
in 2001 to assess the level of interest in developing standards for
epibiota recording. This was done in the form of a ring test which
would help gain an understanding of the current ability of field
surveyors to identify epibiota. Since the pilot study and with the
NMBAQC's support, JNCC has developed a number of
web-based photographic ring tests for
epibiota species.
