How does the sea change over time?

Various game messages in Sunless Sea allude to the fact that the sea might change as days pass. How does it change, exactly?
Best Answer
It doesn't.
The only thing that changes is "Something Awaits You" which can cause random effects at various ports. Also, some ports have stories which progress as time passes.
But it's not like something "changes" in the sense you mean. Islands don't move. New stories don't appear out of nowhere. It's just flavour text.
There are a couple of things which trigger after you've spent a year at Zee, but they're not big events, mostly just related to a couple of officers, and nothing that will affect the game in any significant way.

How has the sea level changed over the years?
When averaged over all of the world's oceans, absolute sea level has risen at an average rate of 0.06 inches per year from 1880 to 2013 (see Figure 1). Since 1993, however, average sea level has risen at a rate of 0.12 to 0.14 inches per year\u2014roughly twice as fast as the long-term trend.How is the sea changing?
As Earth warms, NASA has observed that sea levels are rising. Water expands as it gets warmer. So, warm water takes up more room in our oceans, and this leads to higher sea levels. Another reason that oceans are rising is due to melting ice on land.Why has sea level changed over time?
Sea level rise is caused primarily by two factors related to global warming: the added water from melting ice sheets and glaciers and the expansion of seawater as it warms. The first graph tracks the change in sea level since 1993 as observed by satellites.What causes the water in the sea to change?
Seasonal changes An important cause of intra-annual sea level change is the annual warming/cooling cycle \u2013 in each hemisphere the oceans warm and expand in summer, and cool and contract in the winter. Thus the sea levels in each hemisphere are higher in summer and early autumn, and lower in winter and early spring.GEO-Wednesday: Earth’s History of Changing Sea Level

Answer 2
There are some options on some islands that only become visible once your "Another Day: Time, the Healer" property is large enough. For instance (minor spoiler):
Answer 3
When you visit port with a something awaits you at port token (that you get by basically driving around) you get options you would not have otherwise
