Spatial distribution of total international otter and beam trawling fishing
effort, for all ICES rectangles (0.5 degree latitude by 1 degree longitude) of
the North Sea, covering a 31-year time span from 1985 to 2015. The dataset was
largely reconstructed using compiled effort data from 7 fishing effort
time-series and completed by estimations of missing data. Lat and Long
coordinates in the data represent the centre of each ICES rectangle.

For the 31-year period from 1985 to 2015, we collated or estimated data on
total (demersal) otter and beam trawling effort per year for the North Sea,
defined as ICES Sub-area IV. Specifically, the effort was quantified as number
of hours fishing in a year per ICES rectangle. For each year we compiled data
on trawling effort by vessels landing in Belgium, Denmark, England, France,
Germany, the Netherlands, Norway, Scotland and Sweden, which are the most
significant contributors to trawling effort in the region. Where data for a
particular country and year was missing it was estimated, based on the spatial
distribution of trawling effort by that same country in other periods, and on
the average percentage contribution of the trawling effort by that country to
the total. For each year and ICES rectangle the dataset specifies "Compiled"
and "Estimated" effort, and additionally provides a "Reconstructed" effort
which is the sum of the two. Sources for compiled effort data include the
STECF (Scientific, Technical and Economic Committee for Fisheries), the
MAFCONS Project (Managing Fisheries to Conserve Groundfish and Benthic
Invertebrate Species Diversity), datasets from scientific publications, and
national databases for England, Scotland and Denmark. Following feedback on
manuscript “Couce, E., Schratzberger, M., and Engelhard, G. H.: Reconstructing
three decades of total international trawling effort in the North Sea, Earth
Syst. Sci. Data Discuss, `https://doi.org/10.5194/essd-2019-90`_, in
review, 2019”, the dataset has been updated to include an estimation of errors
for the reconstructed total trawling. Additionally the method for estimating
missing data has been refined, leading to small variations throughout the
period, and beam trawling data for the period 1997-2002 has suffered
significant changes, as German trawling data is now estimated due to shrimp
trawling activity being missing in the MAFCONS dataset for Germany that was
used in the previous version.
