Across Wales Bays and Banks Subtidal Soft Sediment Surveys

The aim of this data capture was to aid in the monitoring and condition assessment of subtidal soft sediment Annex I features in Wales. Subtidal benthic soft sediment repeat sampling is carried out with Special Areas of Conservation (SACs) across Wales to monitor Large Shallow Inlets and Bays, and Estuaries and Sandbank features. Some of these data are collected in conjunction with the Water Framework Directive invertebrate monitoring programme so other data from these locations or the surrounding area may be available upon request from the EA. Surveys took place in large shallow inlets and bays (Conwy Bay, Red Wharf Bay, Cardigan Bay, St Brides Bay, Carmarthen Bay) and designated subtidal sandbank features in Wales. Benthic invertebrate samples are processed by laboratories that are members of the National Marine Biological Analytical Quality Control (NMBAQC) scheme and random samples from each survey are also selected for audit by the NMBAQC contractor. Data entry into Marine Recorder database has not been validated.

Metadata Language: English

Lineage: Monitoring work is carried out at the same sample station by the Environment Agency and Briggs Marine. Sampling is carried out every three years on in a rolling cycle. Previous projects that this work builds on was carried out by CCW. Data captured: Abundance (and in some cases biomass) of benthic invertebrates (per 0.1m2) and granulometry. Supporting determinants are: National Grid References, depth of sample relative to chart datum, salinity (if survey is in an estuary) and sample depth (in grab). Digital images are also taken of each sample both in the grab and after sieving and these form part of the audit trail for each sample. All samples are collected using either a Day grab or a Long arm Van Veen grab (both 0.1m2). Benthic invertebrate samples are sieved over a 0.5 mm mesh, some samples have been split into separate 0.5 mm and 1 mm fractions in order to maintain comparability with historic data sets.

Additional Information: The data is also available through UKDMOS website; http://www.ukdmos.org/v_ukdmos_edios/result.asp
