Measurements of zinc, oxygen, and pH, from sphalerite and ZnS oxidation in seawater
Sorbed-water (H2O-) corrected chemistry for ferromanganese crust samples from the western equatorial Pacific Ocean
Bathymetry of the Republic of the Marshall Islands and vicinity
The bathymetric map of the Republic of the Marshall Islands and vicinity is bounded by a window of latitude 3 to 17 degrees North, longitude 153 to 175 degrees East. The map was compiled from surveys conducted by the USGS, Korean Ocean Research and Development Institute, and published gridded data. In addition to national jurisdictions, island and atoll coastlines are indicated on the map.
