- Improve symbology for "Regional climate models/RACMO model output/Annual mean
wind vectors 1958-2019 (5km)" by removing color mapping to magnitude
values. This was causing conflicts with other layers' color maps.
- Renamed "Geophysics/Heat flux/Heat flow (Colgan et al.)/Flow from multiple
observations (55km)" to "Gridded heat flow (55km)"

We compile and analyze all available geothermal heat flow measurements
collected in and around Greenland into a new database of 419 sites and
generate an accompanying spatial map. This database includes 290 sites
previously reported by the International Heat Flow Commission (IHFC), for
which we now standardize measurement and metadata quality. This database
also includes 129 new sites, which have not been previously reported by the
IHFC. These new sites consist of 88 offshore measurements and 41 onshore
measurements, of which 24 are subglacial. We employ machine learning to
synthesize these in situ measurements into a gridded geothermal heat flow
model that is consistent across both continental and marine areas in and
around Greenland. This model has a native horizontal resolution of 55 km. In
comparison to five existing Greenland geothermal heat flow models, our model
has the lowest mean geothermal heat flow for Greenland onshore areas. Our
modeled heat flow in central North Greenland is highly sensitive to whether
the NGRIP (North GReenland Ice core Project) elevated heat flow anomaly is
included in the training dataset. Our model's most distinctive spatial
feature is pronounced low geothermal heat flow (< 40 mW m−2) across the
North Atlantic Craton of southern Greenland. Crucially, our model does not
show an area of elevated heat flow that might be interpreted as remnant from
the Icelandic plume track. Finally, we discuss the substantial influence of
paleoclimatic and other corrections on geothermal heat flow measurements in
Greenland. The in situ measurement database and gridded heat flow model, as
well as other supporting materials, are freely available from the GEUS
Dataverse (https://doi.org/10.22008/FK2/F9P03L; Colgan and Wansing, 2021).
