Aurora Expeditions' review of the vessel:

In addition to excursions for hiking and honing wildlife photography skills, there’s plenty to do onboard the Sylvia Earle, which features state-of-the-art perks like an ocean-view sauna, a quiet library for reading up on Antarctic history, and stately lounge and deck areas for taking in the views. Thanks to the ship's revolutionary bow design, seasickness is also likely to be less of an issue.
