OSPAR Science Agenda Knowledge Gap Portal
Welcome to the OSPAR Science Agenda knowledge gap portal. The page showcases important scientific questions and evidence needs identified by OSPAR to help protect and sustainably manage the North-East Atlantic. Use the filters and search options below to explore knowledge gaps by topic, category, region, and status, or browse visually to discover areas where new research, data, or collaborations are needed. The aim is to make it easy for anyone - scientists, funders, and policy makers to understand the current priorities, access key details, and get involved in helping to close these important gaps for a healthier ocean future.

Accuracy of estimates of trawling effort
ID Number: BB21.03b
Knowledge gap description: Pressures: Trawling effort may have been overestimated in some areas where vessel speeds were reduced during manoeuvres not linked to commercial bottom fishing (such as entering/exiting ports or during adverse weather conditions), but were erroneously are attributed to trawling.

Information on Benthic species abundance
ID Number: BB21.04a
Knowledge gap description: Biological samples: Benthic species abundance information was not available for some units, limiting assessment of the total area using BH1 as an empirical indicator. So, in the units without species monitoring data, the BH1 is applied by extrapolating the information from the pressure-state curves of the North Iberian Atlantic unit to these units, which reduces the confidence of the assessment in these units.

Sentinels of seabed: monitoring of benthic species in the Gulf of Biscay and South Iberian Atlantic
ID Number: BB21.04b
Knowledge gap description: Biological samples: Increasing monitoring of benthic species (for biomass and abundance) in the common Indicator Assessment units, specifically in the Gulf of Biscay and South Iberian Atlantic, would improve the confidence and accuracy of BH1. The creation of standardised Benthic Monitoring Programmes would help increase data coverage.

Sentinels of seabed: residual environmental variability and abundance of sentinel species.
ID Number: BB21.05c
Knowledge gap description: Environmental variables can affect the proportional abundance of sentinel species. The variability of main environmental variables (sediment and depth) is limited within most of the MSFD broad habitats, but it will be useful if BH1 assessment method explore to account for residual environmental variability by including more factors in the analysis. This may increase the model's accuracy, improving the prediction models.

Climate Change: predictions of future trends for the condition of deep-sea sponge aggregations
ID Number: TBC
Knowledge gap description: Climate Change: The predictions of future trends (2020-2030) for the condition of deep-sea sponge aggregations are challenging. Future environmental conditions in the OSPAR Maritime Area may contribute to deterioration in the condition of deep-sea sponge aggregations. However, further research is needed to advance scientific knowledge on this front.
