2024 NRW Skomer MCZ Benthic Survey

  • English
  • wel
  • All

Grab sampling surveys are conducted within the Skomer Marine Conservation Zone approximately every 3-4 years since 1993.


Since 2009 twelve sites have been re-visited and sampled on each survey. Two samples are collected at each site for infaunal analysis, and one sample obtained for particle size analysis (PSA). The benthic samples are collected using a 0.1m2 Day Grab and sieved with a .5mm sieve. In 2024 the benthic samples were sent to Ocean Ecology Ltd. for infaunal and biomass analysis, and the PSA samples to the NRW laboratory.

Sediment samples are collected using a 0.1m2 Day Grab. Two samples are collected at each site for infaunal analysis and sieved with a 0.5mm sieve, and one additional sample is obtained for particle size analysis (PSA).


In 2024 the benthic samples were sent to Ocean Ecology Limited for infaunal abundance and biomass analysis, and the PSA samples were analysed by the NRW laboratory.
