Global Bathymetry Map

BrianR at Clastic Detritus brought my attention to a new wonderful bathymetric map of the globe. Despite his questionable loyalty to volcanoes, Brian knows a good map when he sees one and I agree that this one is indeed beautiful. GEBCO (General Bathymetric Chart of the Oceans) is an initiative joining the Intergovernmental Oceanographic Commission and International Hydrographic Organization. You can get the high res version of the above here.

Craig McClain is the Executive Director of the Lousiana University Marine Consortium. He has conducted deep-sea research for 20 years and published over 50 papers in the area. He has participated in and led dozens of oceanographic expeditions taken him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses on how energy drives the biology of marine invertebrates from individuals to ecosystems, specifically, seeking to uncover how organisms are adapted to different levels of carbon availability, i.e. food, and how this determines the kinds and number of species in different parts of the oceans. Additionally, Craig is obsessed with the size of things. Sometimes this translated into actually scientific research. Craig’s research has been featured on National Public Radio, Discovery Channel, Fox News, National Geographic and ABC News. In addition to his scientific research, Craig also advocates the need for scientists to connect with the public and is the founder and chief editor of the acclaimed Deep-Sea News (http://deepseanews.com/), a popular ocean-themed blog that has won numerous awards. His writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web.

  1. This is a great looking map, even at this resolution. Brian, did you print the map from GEBCO or procure one? I am wondering how large I could print the 32.5 mb jpeg image.

  2. My Photoshop opens the download image 50″ wide at 150 dpi. If its worth a look at that resolution, it could print on a local plotter.

  3. Peter … I plotted the 32MB version from their site on a 36″ wide paper … it looks pretty good. I should’ve put it on the best quality or futzed w/ the colors a bit … the blues didn’t come out as nice as they looked on the screen.
