Still another profile of ocean cartographer Marie Tharp, this time from the BBC World Service’s Witness program: it’s a nine-minute audio clip called “Mapping the Ocean’s Secrets.” [Osher]

On the WMS Facebook group, Bert Johnson had this to say about this latest profile: “Hers is a standout story, but I wish some of these journalists who keep running these would spend some time and effort discussing some of the other women—known and unknown—who made contributions and helped open the doors of cartography to women.”
