Fig. 2. Metal mass fractions in North
Sea (N. Sea) sediments in and around
OWFs of the German Bight for (A) Cd,
(B) Pb, (C) Zn, (D) Ga and (E) In. The
samples are grouped according to the
official designation of the site devel-
opment plan for the German North Sea
and Baltic Sea by the BSH (2023).
Reference values are given as UCC ?
crustal abundance (Rudnick and Gao,
2003); N. Sea* ? mass fraction range
of North Sea sediments between 2010
and 2020 (Klein et al., 2022a), N. Sea
? mass fraction range of North Sea
sediments between 2008 and 2011
(BSH, 2016) and BSH BC ? BSH back-
ground value (BSH, 2016). *The
following elemental mass fractions are
within Fig. 2 as outliers, but covered by
the labels of the whiskers: Pb: Area-N6,
04/21, 7.5 105 ?g kg 1; Zn: Area N-
6, 04/21, 1.4 105 ?g kg 1; Ga: Area
N-4, 04/21, 2.0 10 ?g kg 1 and In:
Area N-3, 04/18, 9.7 102 ?g kg 1.
