Is there any library that gathers marine species vocalizations?
There are some resources available, but often hampered by the sheer size of these acoustic datasets which makes it difficult to keep them online. http://www.mobysound.org/ has some examples. Also ...

Why does sound from ships propagate better in deep water than in shallow water?
What you're seeing there is an effect of the ocean thermocline. The speed of sound changes rapidly in the upper few hundred meters of the ocean from a combination of temperature and pressure changes (...

Are there conventions for describing the visual representation of sounds on a spectrogram (i.e. names for shape patterns)?
I would look a bit in the bird world for this. There are many visual based ways of describing sounds. Bill Evans' Old Bird is a great example, as his classification of night flight calls includes ...

The fuzzy noise near 0Hz indicates instrument noise to me at first glance. I'd zoom in much further on that to see if there is a strong fundamental frequency.
