A few things to note about life at sea:
"Marine biologists are almost entirely free of any of those silly restrictions that blight the professional landscape of our fellow proletarians. This is because no one really cares about what we do or what we say. You want to come to work dressed in scabrous khaki shorts and a torn black Sandman shirt? Fine. You want to grow a scruffy beard, get a tattoo of a gooseneck barnacle on your arm or burp at inopportune moments? No problem, just do good work."
