I found out last week there is such as thing as iceberg watching as a job. There is a funded, shadowy collective, paid to monitor the world's icebergs for anything about to cause a Titanic-esque shipping catastrophe etc.
I don't know how many catastrophes they've averted, but that's sort of the point, if they do their job, we shouldn't know they exist.
It's like the unsung heroes in agency world. Production, traffic, operations. In media world, there's Ad Ops and sometimes the corner of the insight team that does nothing but TGI runs, Touchpoints Google Trends.
Like the cycling soigneurs, or the aforementioned iceberg watchers, without these folks things would just crumble, but you only appreciate them when they're no longer there, or notice them when things go wrong.
