gmt xyz2grd Data.csv -Guput.nc -I0.0089/0.0089 -R12.7/15.2988/3/6.5066 -D+x"Long[degree]"+y"Lat[degree]"+z"Bouguer_Anomalies[mGal]" -JU33N/12c

Hello @TFJospin. Welcome to the forum!

gmt surface needs a data table (not a grid). So, you could use the file Data.csv in your second command directly.

gmt surface Data.csv -R12.7/15.2988/3/6.5066 -I0.0089/0.0089 -Ghawaii_grd.nc -T0 -C0.1 -Vi
