IA2017 – Radioactive discharges from the nuclear sector have decreased
31st July 2017 by Marine Scotland Communications
OSPAR collects data on authorised discharges and environmental activity concentrations for several radionuclides. For the purpose of evaluation, OSPAR distinguishes those radionuclides that emit alpha radiation (total alpha activity) and those that emit beta radiation (total beta activity). Discharges from fuel reprocessing plants are much reduced but remain the dominant source of discharges from the…

IA2017 – Fish communities show signs of recovery in some areas
24th July 2017 by Marine Scotland Communications
Fish communities form a major element of marine biodiversity and are a key feature in marine foodwebs. Fisheries can thus have a major impact on marine biodiversity. The last OSPAR Quality Status Report (QSR 2010) highlighted, among other issues, that depletion of key predator and prey species and disruption of the marine foodweb were worrying…

IA2017 – Benthic habitats affected by bottom fisheries
17th July 2017 by Marine Scotland Communications
OSPAR is committed to protecting and conserving ecosystems and biodiversity through the management of human activities and is guided by an ecosystem-based approach. Benthic habitats play a key role in marine ecosystems because marine species rely directly or indirectly on the seafloor to feed, hide, rest or reproduce. The last OSPAR Quality Status Report (QSR…

IA2017 – Marine birds in trouble
10th July 2017 by Marine Scotland Communications
Marine birds are valuable indicators of ecosystem condition. OSPAR assesses the abundance and breeding success of marine birds. In the Norwegian Arctic, the Greater North Sea and the Celtic Seas, there has been a considerable (>20%) drop in abundance compared to the levels observed 25 years ago, for more than a quarter of the marine…

Keeping an eye on the coastline with SCObs
23rd January 2017 by Marine Scotland Communications
Scientists in Marine Scotland, along with a small group of voluntary citizen-scientists, have been monitoring the physics, chemistry and biology at multiple sites in Scotland’s coastal waters since 1997. The sites monitored, shown on the left, include Millport, Mallaig, Loch Maddy, Loch Ewe, Scapa, Fair Isle, Scalloway, Cromarty, East Coast and Stonehaven. Consistent ecological time series of data…
