Case (pointed out by Brendan): MCZ:Mala:316997, a marine snail collected:

country=Brazil
locality=off Para
decimalLatitude=3.1416666667
decimalLongitude=-48.1166666667

Comes back with correction of decimalLatitude WAS: 3.1416666667; CHANGED TO: -3.1416666667 (putting it near a Para found on land in Brazil by Geolocate).

Curation comment is:

found 8 possible georeferences with Geolocate engine:GLC:4.94|U:1.01374|eng:1.0 | PARA score:34 -11.560717 -43.278065 km:15862 | PARA score:34 -1.437281 -48.470614 km:5089 | PARA score:34 -12.466667 -38.683333 km:13815 | PARA score:34 -7.016667 -38.733333 km:6827 | PARA score:34 -19.86137 -44.605931 km:25415 | PARA score:34 -7.8413 -36.37457 km:12123 | PARA score:34 -4.0 -53.0 km:9076 | PARA score:34 -22.994722 -47.9375 km:29062 | sign changed coordinates are on the Earth's surface. | Coordinates are inside country (BRAZIL). | Transposed/sign changed coordinates are near (within georeference error radius 20.0 km) georeference of locality from the Geolocate service.

We flag this as needing correction because the coordinate (correctly) doesn't fall inside Brazil.

We aren't processing continent/ocean or the other marine related DarwinCore terms in the input.
