IA2017 – Contaminant concentrations are decreasing, but concerns remain
7th August 2017 by Marine Scotland Communications
OSPAR countries have made significant efforts to reduce discharges, emissions, and losses of contaminants to both air and water. The effect of these efforts is clearly visible in reduced inputs to the Greater North Sea. The observed decreases in contaminant release from land-based sources and the offshore oil and gas industry show the continued progress…

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…

IA2017 – The network of OSPAR Marine Protected Areas is expanding
3rd July 2017 by Marine Scotland Communications
Considerable progress has been made in developing OSPAR’s Marine Protected Area (MPA) network. Since the last OSPAR Quality Status Report (QSR 2010), a further 289 MPAs have been added to the network, bringing the total number to 448. MPAs now cover 5.9% of the OSPAR Maritime Area compared with a total coverage of only 1.1%…

OSPAR’s IA2017 – What is it?
30th June 2017 by Marine Scotland Communications
The OSPAR Intermediate Assessment 2017 (or IA2017K) is an assessment of the marine environment of the North-East Atlantic and its current status. It’s not the first time they’ve done this – its previous holistic assessment, the QSR 2010, was a culmination of ten years of joint assessment and monitoring by OSPAR Contracting Parties and seven years on, with…
