4.2 Publication distribution on a yearly basis
Figure 2 shows the yearly distribution of articles from all the
accessed databases from 2000 to 2021. The figure shows that the peak
number of articles (7) was published in 2006. Four (4) articles followed
this in 2007. In 2004, 2013 and 2018, two (2) articles each were
published. In 2000, 2001, 2002, 2003 and 2019, only a single article
each was published regarding geophysical studies in the Bosumtwi Impact
Crater. No articles were published in 2005, 2008, 2009, 2010, 2011,
2012, 2014, 2015, 2016, 2017 and 2020. The cluster of articles from 2006
and 2007 is due to the multidisciplinary International Continental
Drilling Program (ICDP), a project that took place in 2004. The project
involved unravelling the 3D building blocks of the impact crater,
delineating key lithological units, imaging fault patterns, and defining
key alteration zones (Koeberl et al., 2005 ).
