Information about the sources of our designs:

  NatureBrella LLC produces umbrellas designed on nature- or science-inspired themes. Our first two products are umbrellas featuring circum-polar seafloor maps. The Arctic Ocean umbrella is based upon the International Bathymetric Chart of the Arctic Ocean; the Antarctica umbrella is based upon an ETOP02 map provided by NOAA/NGDC.  

Our Arctic Ocean and Antarctica
umbrella designs are derived from actual seafloor maps.

The Arctic Ocean

design was adapted from the International Bathymetric Chart of the Arctic Ocean (IBCAO), a project involving scientists from institutions in eleven countries, who have collaborated to produce the most definitive map of Arctic Ocean Bathymetry.
For more information about IBCAO, see www.ibcao.org.

   
Artic Map
Antactica Map
The Antarctic Ocean

design was adapted from a South-Pole-Centric orthogonal projection of the Southern Hemisphere obtained from NOAA/NGDC.
The bathymetry portrayed is Smith & Sandwell's predicted bathymetry from satellite altimetry, terrestrial areas are overlain with satellite mosaic images.
